Abstract

Abstract

The water gushing test in an artesian well, a simple and economical test method for confirmation of the hydrogeology parameter in the water containing layer, basically belongs to the test of constant drawdown yield. During the water gushing test in the infinite confined aquifer, the inrush of water and the random water head H in the confined aquifer decrease with the time, except the well itself, but the fall of well water s_w is kept unchangeable. The calculation of the hydrogeology parameter using the linear diagrammatized method l/Q-lg t in the constant drawdown yield test of single well, helps the authors to establish the linear diagrammatized method, s/Q-lg t method, in which one well is a main hole while the other wells can be used for watching the lowering of water.
