METHOD FOR PREVENTING FLOODING OF TERRITORIES DURING LARGE-SCALE AND LOCAL FLOODING ON RIVER DRAINAGE AREAS AND SYSTEM FOR ITS IMPLEMENTATION

摘要

1. A way to prevent flooding of territories during large-scale and local floods on the river catchment area, which consists in laying channels from the water bodies located in the flood zone to drain excess water into water bodies located below and outside the flood zone, for which purpose in areas the catchment areas of rivers, pre-identify areas susceptible to flooding during floods, create artificial and / or use natural reservoirs to receive excess water, designate places for laying out canals and they carry out calculations of their parameters, characterized in that the level mark of the bottom of each outlet channel at the place of excess water discharge from the reservoir is performed at or slightly above the normal level of the surface of the water in the reservoir, corresponding to the average value of the stable level observed over many years, the bottom along the length of each branch channel is performed with a slope i in the direction of the downstream reservoir. 2. The method according to claim 1, characterized in that the number of outlet channels and their width b are taken from the calculation of the maximum possible volume of excess water discharged from water bodies, subject to the minimum depth h min of channels. The method according to claim 2, characterized in that at least one channel for draining excess water from the river and / or river channel and / or from the lake and / or reservoir to the downstream river bed and / or to the lake and / or reservoir, and / or at sea. 4. The method according to claim 3, characterized in that along the length of the outlet channel perform a rectilinear or curved shape. System to prevent flooding of territories during large-scale and locale
