JPS5952009A - Increasing of water amount stored in water reservoir - Google Patents

Abstract

PURPOSE:To increase the amount of water to be stored in a water reservoir by raising the flowing water coefficient by a method in which miscellaneous trees and grass, etc., other than medium and large trees, among plants in the area surrounding a water reservoir, are removed out, and a water-proof material is laid on the ground's surface. CONSTITUTION:Of plants growing in the area A surrounding a water reservoir, miscellaneous trees, grass, etc., other than medium and large trees are removed out, and a water-proof material 2, e.g., concrete, asphalt, vinyl resin, etc., is laid on the ground's surface. Rain water which falls within the area A flows into the water reservoir B along the water-proof material 2 without permeating into the ground, whereby raising the flowing water coefficient. The amount of water to be stored in the water reservoir can thus be increased, contributing to eliminate problem of water shortage.

Description

[Detailed description of the invention] This invention relates to a method for increasing the amount of water stored in a reservoir.

In recent years, the demand for water has been increasing year by year. However, the amount of water stored in a reservoir is expressed using the following formula: Storage amount = (annual rainfall) x (basin area) x (flow coefficient), and the annual rainfall depends on slight changes in the weather. Although it increases and decreases, it is almost constant, and the basin area is also constant. Therefore, the present invention provides a method for increasing the amount of water stored in a reservoir by artificially increasing the water flow coefficient.

Hereinafter, one embodiment of the present invention will be described according to the drawings.Among the plants growing in the basin (N) facing the reservoir, medium and large standing trees (1) are left and other miscellaneous trees, grass, etc. are removed. , Waterproofing material (2) such as concrete, asphalt, or vinyl is laid on the ground surface.

If there are roads, houses, parks, etc. around the reservoir (B), drill a groove (0) on the side of these mountains and connect the pipe (D) from the groove to supply water to the reservoir. Let it flow. However, the pipe (D) should be buried underground in roads, houses, parks, etc.

In addition, if the bottom of the reservoir is filled with sediment that has flowed in with rainwater, etc. and the volume has decreased, waterproofing material may be used on the bottom and sides of the reservoir after removing this sediment. n') is a stirring device, and (F) is a valve.

According to this invention, rainwater that falls within the basin area can be collected using waterproof material (
2), the water flows into the reservoir through the waterproof material (2) without sinking into the ground, and as a result, the water flow coefficient can be increased. By installing (2), the water storage capacity can be expanded, which will be part of the solution to water shortages, and will have extremely beneficial effects.
