Rate Calculation on Weir-Opening Crests and Embankments of Drowned Polders
Examined: Rate calculation on crests of weir-openings of drowned polders at arrangement of weir-openings at upper, lower transverse and middle part of longitudinal embankment. Stated: Dependences for approximate calculation of dynamics of levels in drowned polder and rates at weir-opening crest during flood. Proposals are given regarding the procedure of structural design of drowned polder, resistant to washout during flood.
