An impact of tectonic structures on the groundwater circulation and losses from surface accumulation in the area of the left bank of Lazići dam on the Tara MTS

Abstract

The process of water leakage determination in the area of water accumulation and left bank of the Lazići dam requires extensive application of different methods: very detailed monitoring data, tracing, structural and tectonic investigations, etc. Obtained results of water losses from the reservoir indicate a tendency for further increases. According to the applied analyses, two zones at the narrow zone of the grout curtain, characterized by different hydraulic mechanisms were detected. Additionally, the general direction of water leakage from the reservoir was detected. An important conclusion is that in such hydraulically intense conditions leakage is unstoppable, but can be partially controlled or slowed down.
