PROCESS PREVENTING FLOODING OF ARABLE LAND BY FLOODWATER OF MOUNTAIN RIVER Russian patent published in 2004 - IPC

FIELD: hydraulic power engineering, amelioration. SUBSTANCE: invention is aimed at generation of electricity and prevention of destructive effect of floodwater in season of long showers in mountains. Process includes communication of water inlet with watertight pressure tunnel and arrangement of cascade of derivative hydraulic power stations with growing efficiency in direction of flow. Water is taken from water storage formed across mountain river by construction of dam at lower boundary of fall of intensive precipitation. Pressure tunnel communicates directly with shore boundary of sea or lake with the help of derivative pressure conduit controlling flow rate of water with the use of water locks or by transfer of hydraulic units to mode of electric pump to pump over water through another pipeline to arable lands for irrigation. EFFECT: removal of problem of unpredictable, emergency situation in lower part of river course, provision for growth of cultures with longer vegetation period. 1 dwg
