Solar power plants on slopes extended by flood walls and water storage are the world’s cheapest form of flood prevention. With this new form of solar power plants we fight the flood problem where it arises. Please find attached our presentation and the film.
This rainfall-flow calculation shows a south-facing slope with a grass surface.
During heavy rainfall, a large amount of water collects here and a wide stream of water, which is only 1 cm to 5 cm high, flows downwards.
The water collects in one place and swells into a torrent, first 20 cm high and later even 1 m high, which then already has considerable destructive power. Moreover, such streams merge with other rivers and thus create real flood waves. We can effectively and economically avoid this one stream with only 5 rows of solar plants and reduce it to a small, relatively uncritical trickle.
Due to the flood protection wall and the collection basins, which we have placed centrally under the solar plants, we can retain a very large amount of water for a very long time.
The water is only used in a controlled way and when needed and cannot soak the slope and thus destabilise it. Muddying of the basins is minimal as the water is collected at regular intervals before it has gained speed and thus mud.
Farming is still possible between the rows, which are up to 50 m apart from each other. In addition, a higher yield can be expected on the remaining area due to the wind protection and better water supply.
