An example of regulation of karst aquifer

One of the successful for artificial regulation of karst aquifer projects has been developed for regional water supply for the towns in the region of Timok (eastern part of Serbia). The investigations included the test of long-standing pumping from the siphon channel of Mrljis spring, during which almost twice as large yield was obtained compared to the natural regime of discharge (from 165 to 320 1/s). The water regulation project includes, water abstraction from large springs, the construction of vertical wells up to 100 m deep at three most favourable localities, about 500 m in diameter from the main spring. A hydrodynamic model of karst aquifer has been used as one of the bases for the forecasting of the conditions and possibilities for ground water recovery in this area.
