They are looking into something similar in the UK to manage floodwaters, so that instead of funneling water fast and out, which massively increases erosion and sometimes overwhelms bridges down stream, you work out where you can let the water hang around in times of flood and make agreements with farmers to have flash flood basins.
- jdlshore 12y agoPortland Oregon does something similar on a much smaller scale. To prevent the sewage system from being overwhelmed in periods of heavy rain, they've installed "swales" and stormwater planters [1] that redirect the water into the ground. I've walked around in the rain and the difference is remarkable--typical curb drains would be overflowing with water, while the drains near the swales and planters would be dry.
