FIELD: hydraulic structures, particularly shore opened self-acted appurtenant spillaway structures adapted for flood water discharge. ^ SUBSTANCE: spillaway structure comprises head discharge part, water offtake channel and end part for mating pools. End part is provided with outlets arranged in side walls transversely to coarse valley. The last in flow direction outlet has triangular cross-section. Common front of water outlets is determined from provision of estimated flow distribution over slope with velocity preventing washing-away vegetative cover from valley slope. ^ EFFECT: increased reliability of protection against flood water, decreased damage of hydraulic structures and environment, reduced cost of hydraulic structure erection due to expending money only for performing earthworks. ^ 2 dwg |
