OVERFLOW DAMS ON SMOLL CHANNELS OF IRRIGATION SYSTEMS
The article has data on potential designs of overflow structures made of soil rather than concrete. The most reliable and cheap ones are dykes made of sandbags. This viewpoint is substantiated by the operation of peatland irrigation systems, constructed in the Moscow region in 2011 — 2012. The construction of overflow sandbag dykes must have slope/riverbed protection structures to withstand their erosion by open and filtration flows of the downstream. Designs of overflow dykes having their downstream sides protected by geosynthetic coats, which are patented by other hydraulic engineers, have proven unreliable.
