@BashStKid This is #Devon #rain #floods #fields #food there are roads narrow enough to surprise visitors partly due to the high banks, hedges etc.

Too much rain for them.

While one may stop the rain running out of the field, it forms a puddle, lake, unmanageable anaerobic mess, within the field, where crops were hoped for.

Reducing the water landing in the field, whatever one does with it, is worth thinking about, I think.

Draining Lago di Garazas, the giant puddle that I had to wade through every time I wanted to fetch something from the garbarn.

Next to the barn was a mysterious old hole with some pipes in it which looked like part of an old drainage system. Good opportunity to test that. I pumped the entire giant puddle into that and it disappeared into a downhill pipe that emptied instantly.

Nice, because the yard could do with some drainage, as you can see.

Re: A drainage problem at the new football field site

The only other drainage problem I found was that they still had this drain covered so the water was overflowing this bathroom area and down into the parking lot.

It does show a good view of the front of the stadium on a cloudy day though :-)

Re: A drainage problem at the new football field site

At least one of the drains is working.

They did a lot of work and have 3 drainage basins on the site. Eventually the water on this site will drain as part of the Alum creek watershed.

A drainage problem at the new football field site

They spent a few months moving dirt and setting up drainage for the site, and it seems like there are a few problems from the rain storm that passed through this morning.

Flow Through Granular Beds

We often rely on water draining through beds of grains, whether it’s the soil foundation beneath a building or the sand-and-gravel-filter used in water treatment. But how does water move through these tortuous porous passages? That’s what we see in this video, which places grains in a jig resembling an ant farm and lets us watch as water–and air–drain through the grains. The result is more complicated than you might imagine, with dry pockets, weak spots, and developing sinkholes. (Video and image credit: J. Choi et al.)

#UK - How #WildlifeCorridors Are Helping Animals Survive In #Urban Areas

By Sarah Whitmore / 20 May 2025

Excerpt: "How animals actually use these corridors

"Let’s take #hedgehogs. Urban hedgehog populations are declining sharply — partly because their ability to roam has been limited by garden fences, walls, and roads. A hedgehog might need to travel over a kilometre in a single night to find enough food and a mate. The Hedgehog Street campaign has shown that something as simple as a 13 cm hole in a garden fence can turn a neighbourhood into a habitat network.

"#Bats, which are legally protected in the UK, rely on uninterrupted linear features like tree rows and waterways to navigate. When gaps appear in these features — from tree removal, #LightPollution, or #development — their movement is disrupted. Creating corridors that link #roosting sites with feeding grounds can dramatically increase their chances of survival.

"#Amphibians, especially species like common toads, face seasonal danger when crossing roads to reach breeding ponds. #UnderRoadTunnels and #AmphibianFriendly #drainage routes, used in projects supported by organisations like #Froglife, have proven successful at reducing #roadkill and supporting local populations.

"#Pollinators like #bees and #butterflies also benefit immensely from corridors. Isolated #wildflower patches can’t support long-distance foraging. But when these patches are linked — even via #roadside verges or #SchoolGardens — insects can move more freely and establish healthier, more resilient populations."

Draining Topography is Hard

At first glance, draining an ocean seems simple like a simple problem: just put a drain at the lowest point. But, as shown in this Minute Physics video, the problem is harder than it sounds because drainage depends not just on a point’s elevation but also on the path that leads to the drain. Fortunately, Henry has some clever methods for figuring out which areas would drain and how. (Video and image credit: Minute Physics)

Estimating Increased Transient Water Storage With Increases In Beaver Dam Activity
--
https://doi.org/10.3390/w16111515 <-- shared paper
--
“Dam building by beaver (Castor spp.) slows water movement through montane valleys, increasing transient water storage and the diversity of residence times. In some cases, water storage created by beaver dam construction is correlated to changes in streamflow magnitude and timing. However, the total amount of additional surface and groundwater storage that beaver dams may create (and, thus, their maximum potential impact on streamflow) has not been contextualized in the water balance of larger river basins..."
