ABSTRACT
Based on the water balance studies it is possible to obtain data for the assessment of volume/discharge of source water, further acting in groundwater circulation in the recharge area of the landslide, and its distribution in time. Depending on the climatic conditions, the value of evapotranspiration ranges from zero values up to the whole volume of monthly precipitation totals and in extreme periods also the soil moisture (water stored in soil cover) is evaporated. Based on the analyses of discharge, we can observe that the water taking part in the deep circulation underground has a possibility of flow concentration. Discharging surface waters and subsurface waters are not capable of flow concentration and the discharge is of aerial character. Based on the capability of groundwater flow concentration with the rock mass we can optimise the type of drainage element and its placement in the process of landslide remediation.
