Prevention of flood from a water channel

Abstract

Preventing a flood by lowering the water level of the water channel in the flood prone zone by methods consisting of pushing large quantities of water downstream and partially blocking the inflow of water at various strategic locations.

1 . A method of preventing a flood in a water channel, comprising:
 a means of pushing downstream, substantially large quantities of water of said channel at its downstream location,   whereby, due to said pushing, the water level in said channel will be sufficiently lowered.   
   
   
       2 . The means of  claim 1  comprising a suitable floating vessel having a plurality of substantially large paddles to push water,
 whereby, by holding said vessel in a substantially stationary position in relation to said channel's water flow, substantially large quantities of water can be pushed from upstream to downstream.   
   
   
       3 . A method of preventing a flood in a water channel, comprising:
 a means of temporarily slowing down the addition of water into said channel at an upstream location,   whereby due to said slowing down, water level in said channel will be sufficiently lowered.   
   
   
       4 . The means of  claim 3  comprising a suitable floating vessel having a large paddle which may be immersed into the water in a direction perpendicular to the direction of said water's flow and held stationary,
 whereby, by holding said vessel in a substantially stationary position in relation to said channel's water, substantially large quantities of water can be slowed from flowing upstream to downstream.
