Unrelated to survival these are fantastic fun on beaches. We found one and started digging to make a pool, then a wiggly run to the beach to create a river. Blocking and changing it was great with the kids. Then we found more, so we channeled things to join them together. Then more, and more. By the end we'd joined maybe 10 or more points together over 30+m wide, kids and adults from a bunch of families all with spades rapidly redigging various channels. TBH I think I enjoyed it more than the kids. I even finally managed to make an oxbow lake - a result underappreciated by my four year old.
