put in a drainage ditch, french type drain make sure it's well maintained cleared , you never know when the biblical type weather will occur I live in Spain and it comes when it comes

exactly what happened to me, I learned and now I have dug drainage and , outlets from my field that feeds into the local free water rights system and then into the ramble; when the worst flood happen my veg and Polly tunnels were underwater for about a week. you also have to be careful where you plant some trees olives like water but if they are fully matured , young ones will rot at the roots,, fruits like apricot and young peach trees, also mango if the trees are too young they do not like standing in too much water, we lost our mango but the sugar fruit survived. soft. but brassicas like lettuce died instantly cabbage, greens and peppers survived

Exactly you no now where the waters goes plan round it , ,like you said you just started so not much lost

my advice is after water is down a bit clean all those water drain ditches near your greenhouse where the canes are must be clogged with debris and overgrown canes, near ibc same situation if those drain ditches are not maintained before rain arrives it will flood your land, all the best

Thats likely a blessing in disguise. They seem bad at first but all birth is painful and chaotic. All that water will raise depleted ground water levels, recharge underground wells, and stimulate the actions of soil microbes which will bring enhanced fertility in the coming season .

In Portugal we have a saying "ou 8 ou 80, foda-se"

Sorry to see all your hard work crumbling in front of your eyes ,farming is very challenging especially in extreme weather but you have the right attitude to deal with any potential problem, I think a good plan to manage the water is a must,a pond to save all that rain water would be the way forward whatever the rain fall damages would be used to regrow later ,good luck thanks for sharing.

If you still want to stay there you could grow fruit trees that won't be as badly affected by rains.

Scary.

Possibly there were incidents prior than your experience, that the flat areas were previously flooded?

Sorry for all your bad experience but try to keep away from flood or dried out river bed areas. If you research, you may find out it is not the first time this happend.

Best luck friends.. wishing you quick recovery.

Want to be clear here. What I'm about to say IS NOT criticism. More like a set of constructive observations.
This on (seems) like a catastrophe. It's actually an amazing opportunity to assess natural water flows across the farm's topography and the effectiveness or lack thereof of your land/H20 management systems. It means that you can now best assess (where) to place all of the necessary water management features appropriate to the farm's topography. It (means) that you'll be able to collect & store a huge amount of H2O, (greatly) minimising the serious amount of soil erosion you've experienced during this flood event.

At a quick glance you have minimal number of swales & none of them either sufficiently deep enough nor very long & seem rather piecemeal in design. They need to be deep enough to hold significant amounts of H20 (&) spread out over a much wider distance across the farm on contour & in particularly dry situations, it can be particularly useful to (deeply) rip the bottom of the swales using either a pick axe or if possible, mechanical digging equipment, to allow more H2O sequestration than would normally be the case with in most swales. Also I noticed that you didn't install any 'swivel pipes' in the berm walls to allow for excess H20 to drain away into another part of your water management system. A swivel pipe is a plastic plumbing pipe that has an 'elbow joint' with the upward portion pointing upward (above) the top of the berm. When building swales, bury the swivel pipes (at the bottom) of the berms. When swaps are full, you simply swivel them from an upright position down to a side on one to allow drainage, returning to an upright position when sufficient excess H20 has drained away. Geoff Lawton amply demonstrates this in his YouTube channel videos.

I've not seen all of your other videos so please forgive me if I'm overlooking something here, but I couldn't see any evidence of dams at (different) levels on the property. It REALLY helps with major flood events if you can install a (series) of dams of reasonable size/s ranging from near the top of the property & then every so often moving downwards until at the lowest point, you put in as large a dam as possible as the size of the property will allow. In each dam, it's crucial to include adequate 'spillways', again to prevent blowouts as seems to have happened to some of your swales/berm walls.
Your driveway & trackways have (not) been designed with the correct camber. Camber design/inclusion is important as it helps to direct water off of the surfaces into drainage systems, preventing erosion, flooding & general impassibility – in your case, bogginess. The access tracks & driveway need to be regraded so that H20 naturally runs off at a slight slope (&) into drainage swales that empty into deeper swales & or a dam system.
You (may) if possible/practicable, find it useful to relocate the access tracks so that they (mainly) run along on contour instead of simply going by the shortest route – in your case – downwards, which means you created an artificial dry creek bed or wadi until it rains and – well – you've seen the results.

Climate change IS going make these more extreme flood events happen more frequently. As such, depending on how well you know & get on with your neighbours, & where the area's property boundaries are, I actually think it would be an excellent idea to see if a cohesive cross boundary swale & berm + dam water management could be created to the benefit of all of the local community, both in drought & flood. For example: once one property has captured & stored the maximum amount of H20 possible, swales & dams designed to do so, could then be allowed to flow into/onto the neighbouring property in coordination with the relevant neighbours. Additionally, how much tree cover is there both on your farm, the neighbouring properties & local authority land? Trees once established, really help to sequester H20 & if planted in the (bottom) of swales, will both establish more quickly & require less maintenance in hot arid climates. A coordinated tree planting scheme of the (right) species in the (right) places can reduce flood event impacts & there may be grant schemes to assist with funding.
Hope @ least (some) of these suggestions will be useful. All the best.
P.S. Just a quick afterthought. If you're not already familiar with Geoff Lawton & the Australian Permaculture Institute & the Geoff Lawton YouTube channel, I'd heartily recommend taking a look. Also it's well worth taking a gander at the Institute's website. They run online & in-person courses & advise governments, NGO's & individuals worldwide. The Australian government have worked with Geoff and his wife Nadia, instigating permaculture design into the Australian school curriculum.
There's also a series of videos about the Al Baydha Project in Saudi Arabia. Some of the techniques used there would also be applicable such as 'check dams' to slow the rate of flow.

Interesting video!

Wow #Prayers 🙏 Hmmm seems So-called Climate change agenda 🤔 in Portugal from drought to endless raining back to back, for real & Many Countries around the Globe!🙃

So sorry for the destruction of your hard work!!! The way you reacted to all that chaos shows that youre a strong person. Im sure youll rise above it!

Channel the water a little – directed away.. hope you recover

I'm kinda curious if you’ve checked a topographic map before you’ve planned where to locate your poly tunnel? AFAIK, hikers who prepare for the night know where not to build their tents, even more important if not done only temporary…

Save collect divert as much water as you can because you are going to need it in the dry spell. Water will find away. Dig ditches drainage channels. Just do what you can slowly bringing the water under control. Good luck. You might have to consider that the tunnel is in the wrong place.

First thing i'd check in with the neighbours to see how they fared and if this is a normal rain event for this time of year…
Unfortunately with water flowing like that I'm not sure a pond will work.. it will just get washed away…
Pushing water away from your property using the hill itself is worth a try… swale type drains towards the low side of the property on a slow angle so it doesn't eat away the hill..
BUT if this is a once in 10 year kind of thing… just go with it.. put some extra protection around your tunnel so it doesn't take the force of the water directly.. and accept the loss every now and again…

You keep going over the same things. It's done. Try and move on. I'd be more interested in the solution now. A whole video of much of the same damage etc is boring. Move everything to higher ground and dig more gullies to take excess water away. Hope the next video shows progress.

You absolutely need to shift out of the water course. At least you now know where not to build. I would let the gardens that are left remain until you re-establish things.

hi. just came through similar situation in Aus. 3 years worst drought on record followed by wettest year on record. check out Geoff Lawton, he has great ideas about permaculture in areas of intense rain and drought. good luck.

Where is this farm?

Oh my, the weather wasn't much better down south in Lagos. Lots of flooding and land washed away.

Sorry to see your well has flooded. Hope you have access to another water source?

Move the growing area up hill.

Uff fires a few months ago, now floods. Its like Australia there right now!
Also I'd run out RIGHT NOW while you still can and mark the water levels!!! then you can stake them and mark the flood lines. They have them on the roads up in Queensland and Northern NSW. Then you can work around these flood marks. I did a permaculture course at the Zaytuna farm years ago and he's got amazing flood mitigation on the property. Might be worth doing an earthworks course as well if you need a bit more knowledge on how to implement it.

da ist Portugal für bekannt viel Überschwemmungen ,viel Unwetter

Yeah, water is always going to move down to a stream or valley floor. I was raised on a high country sheep farm in New Zealand, unfortunately this happens from time to time. Definitely move your garden to a high point. You could use that area for some sort of crop that is harvested before autumn.

stop whining like a new yorker! Mother nature has taught you some valuable lessons, so you will learn quicker if you stop talking and do something about it

🙏

My wife and I are on the road and only saw the flooding on the news while in Funchal. Our home is in Faro. I hope we are Ok when we get back Home. Best of luck to you and your family.

If I can help in anyway, give me a shout. I have a good few years experience in civil engineering and flood management. Happy to advice.

Are you new to area? Does the land flood regularly? Did long time locals know this and you didn't? I have relatives who moved to an area and they were sold land that does not absorb the standing rainfall. They could have 6" of water standing for a week or more and they live with plastic bags and boots, all because they were out of towners, taken advantage of or simply didn't know better. Buyer beware! Your cute little valley could get hit again and again. I'm upset for you!!!! All that work!!! ugh. I personally wouldn't want to go through this ONCE, let alone several times a decade! I don't suppose you have farm insurance?

So sorry for what , sadly, is a preventable loss. Talking with the longtime residents might have suggested mitigations.
As others have suggested and given the forecast for the global future what you have experienced and the unbearable summer temperatures put the two experiences together and, while the water is here, draw a map, take measurements and plan how you can save the water (damming and redirecting).
Somehow the ideal situation would be to construct ponds where the heaviest concentrations of gathered rains have shown the deepest.
Renting a digger for your future ponds would be a suggestion when the water and land subsides. Terracing seems like a great idea, with swales.
Raised beds supported by flat stones needs also to be considered. Wish I was closer and able but I have signed up and will offer what help I can.
TAKE LOTS OF PHOTOS AND VIDEOS WHILE YOU CAN.
Draw potential changes you can think of. This time, once you have gotten over the initial shock, is super valuable for coming up for potential changes.

Oh wow !! I have not seen so much flooding in our region – Algarve . Would have to reconsider where to move veggies because it’s very possible that this could happen again . Wish you luck

I run a small market garden and it might look bad now, but there's always an answer to this temporary setback. I suspect that the locals would have known abut this issue, if there are any fairly close by to ask… You have to assume this will happen again )probably every year), so your growing areas should go higher up – anywhere the water's not right now. It looks like you're in some sort of temporary river or flood plain and you'll never be able to divert the water without a major construction project (although, if you have the money, building a huge concrete water tank, of the type you see all over Europe, would help in the hot season… Maybe you'll lose production this season, but you'll now be able to avoid the same problem next season, and building back will always allow you to improve what you did the first time – and it'll be much quicker to do, too. My experience has been large setbacks to start, getting progressively smaller as the seasons go by. Good luck!

I have a feeling you did not thought about the high and low points of the property. But do give a thought on water capturing Percolation systems

Hence you need to dig trenches and wells for water collection all over the property. Water capturing Percolation systems are pretty easy a typical well covered in layers of rocks and boulders and last layer being sand to filter water. Andrew milson and his YT channel you can get ideas from.

I have a farm in inland Spain. Like you have been surprised by the amount of rain falling and turning my land in one big river. Am in a valley too. What I have done is creating an artificial rio with a bulldozer. For my situation it has proved to be the solucion. Design a water structures to stop water running all over the place. Hope it might help you. Am feeling with you. Take care.

So sorry for what's happened to all your hard work. It's devastating.Ive been looking at the geo engineering in your skies. assume is happening on East coast of Australia🇦🇺. It's not mother nature anymore.
Look up Climate Viewer Jim Lee utube to understand weather modification.
Well wishes

Realtor just want to sale and make sales they don say if they know and hurts
a problem in the land .

Plow a dam to funnel water flows into big pond??

Drought then rain is why you want the water to go in the ground swales leaking wiers are going to hold water on the ground and can cause problems ponds in your area are not as wise as a raised leaking wiers made from rock Stick higher in your landscap so it stays wet for longer higher

Swales and a welk where water can flow into to.

Don't give up! As they say it's a learning curve. Now you definitely know where not to plant becuz of the natural topography! Use it to your advantage, move buildings, dig a pond/lake area into the center of your property to slow the flow and also dig trenches to direct the water away safely from your buildings! Wish I could help you rebuild. It will just be a different layout.

Just a bit of advice on flood management:
This year the rainfall in Portugal has been unprecedented (as was the scorching summer temperatures) and you won't be able to do much to avoid similar flooding in future, as global warming is bringing a lot of change to previous stable weather parterns, but you can do some preparation in the dry season for damage limitation in winter.
This may help:
> Now is the right time to observe where most of the rain water is coming from and check if there is anything blocking its passage to the nearest stream.
> Keep all streams, trenches and ditches around your land clean of vegetation and debris (done during dry season before winter)
> Don't fill in or flatten any old trenches. If you already did, open them up again, as they were there for a reason — to drain rainwater away from the land.
> You mention the rainwater was collecting on the nearby roads and ending up on your land. Check if these roads have the "valetas" / ditches open and clean. Oftentimes when roads are repaired, the contractors flaten & fill the "valetas" and then the winter comes and the rain runs right down the roads instead of being channelled by the "valetas" to streams.
> Maintenance of PUBLIC roads (even untarmacked lanes) is the responsability of the local Junta de Freguesia. Contact the the Presidente da Junta and ask if they can do anything to maintain the road "valetas" near you.
In our neck of the woods, the local Junta comes every year with heavy machinery and keeps all roads in good maintenance, even forest roads.
> Consider if constructing a strong wall would prevent the flood water entering you land, or at least divert it towards the nearrest stream.
> You ask if you should reposition your greenhouse. Difficult to say as nobody knows if floods will become an annual event. If your grenhouse is not in the lowest point of your land, it may be possible to have channels and ditches (big and small) that collect and redirect rainwater away from your greenhouse area.
From your video it looks like your property slopes towards a lower point. This is where the water gathers in a torrent and nothing will stand in its path. But without visiting the site it is difficult to see if water could be diverted from the area where the greenhouse is.
> Ask the older local residents (those that live there permanently) their opinion on how best to solve or prevent your problem. They are full of priceless old wisdom & experience. You could also ask the Presidente da Junta, if they are any good, they'll come to see the problem with the roads and advise you.
I think most expats living in Portugal live in their own expat bubble and miss out on a lot of local information because they don't mix with locals. The portuguese are very easy to speak to, just say:
"Tenho a minha terra coberta de agua / inundada. O que posso fazer para evitar isto no proximo ano?" = I have my land covered in water / flooded. What can I do to avoid this next year?"
Good luck!
That's rural life in Portugal: sometimes it's too dry, sometimes it's too hot, sometimes it's too wet… too windy… you loose all your crops in a freak storm. Sometimes you loose your roof too. But the worst are the fires.
