Being the management system in order to manage ground-water level

摘要

PROBLEM TO BE SOLVED: To provide a control system of ground water and a control method of the ground water by which an amount of pumped water, an amount of recharged water, and a level of the ground water around a pumping well and a recharging well are automatically controlled, while the running cost is kept low.;SOLUTION: The control system 1 of the ground water comprises: a pumping means 5 for pumping up the ground water from the pumping well 3; a water level gauge 7 within a range of influence on the side of the pumping well; a water level gauge 9 out of the range of influence on the side of the pumping well for detecting the ground water level in a natural condition of the natural ground; a water conveying means 13 for conveying the ground water pumped up by the pumping means 5 to the recharging well 11; a recharging means 15 for recharging the ground water to the recharge well 11; a water level gauge 17 within the range of influence on the side of the recharging well; a water level gauge 19 out of the range of influence on the side of the recharging well for detecting the ground water level in the natural condition of the natural ground; and a control device 21 for controlling the pumping means 5, the recharging means 15 and the water conveying means 13 so that the amount of water pumped up from the pumping well 3 becomes the necessary minimum limit, and the amount of recharged water of the pumped ground water becomes maximum.;COPYRIGHT: (C)2007,JPO&INPIT
