Abstract: The paper states that groundwater utilization shoulcl be based on the assumption that their resource may be recharged and this process is controllable. The groundwater intakes should, therefore, be arranged to facilitate recharging of used aquifers. The artificial groundwater recharge (AGWR) systems usually operate in complicated conditions. For thi s reason, forecas t of their efficiency requires infiltration estimates to be obtained by the following procedures. A site for projected AGWR is chosen according to the results of the groundwater flow studies. A calculation procedure is developed with the boundary and initial conditions specified. The method is ch osen for assessmen t of groun dwater storage in the natural conclitions and those w ith the captage facilities constructed and AGWR implemented. One of the alternative assessment methods may be analytical calculation and computerized models. To obtain the infiltration es七imates, a mathematical model is developed for recharge processes, and algorithms are composed. Discussion is given of the algorithm and program for computation of infiltration reservoirs. There are two cases to be encountered in the design: with capacities and yields of the infiltration structures known, the total infiltration area and number of reservoirs are calculated; with the infiltration area and number of reservoirs known, the structure yield is determined. Analytical calculations for AGWR involving pumped wells are. presented. The calculation method for intensified groundwater withdrawal with subsequent recharge is given.
