Result of numerical modelling of groundwater resource in the Shiraki catchment
Abstract
In order to assessment water resource, a numerical model of groundwater was elaborated for Shiraki area. It is consists of 3 layers. Each layer represents a porous material with different infiltration properties. The model was calibrated in transient transport mode to tritium concentration measured in boreholes and springs located in Shiraki area. Tritium was assigned as a single mobile species, not reacting with chemical elements and concentrated in water, what allowed determining the residence time of groundwater flow. The model estimated discharge and recharge zones, groundwater flow directions and velocities as well as groundwater age for Shiraki area. It is recommended to enhance the use of waters from the karstic formations as alternative drinking water sources.References
