Features of natural groundwater resource formation in Brest hydrogeological basin

The article presents a new methodological approach to assess the natural resources of groundwater in poorly drained river basins. Its implementation is demonstrated through the watersheds of the Lesnaya and Mukhavets rivers, which occupy a significant portion of Brest hydrogeological basin. To evaluate the structure of the balance of natural groundwater resources, a numerical geofiltering model for the watersheds of the Lesnaya and Mukhavets rivers was developed. The model was created using the licensed software of ModTech by Geolink LLC. The calibration process involved the obtaining of the specified amount of groundwater discharge into the rivers and reconciling the modeled and actual groundwater pressures during the summer-autumn low water period. Satisfactory calibration results were achieved after the segmenting of the modeled water inflow into the computational blocks of the model, dividing the groundwater discharge into the rivers and evapotranspiration.

It was established that in the long-term perspective, the area of modeled watersheds, concerning the process of water exchange between the land surface and the depression surface of groundwater, can be divided into approximately equal parts: 1) territory with a positive value of groundwater infiltration recharge; 2) territory where, in the long-term perspective, groundwater discharge in the form of evapotranspiration predominates.

A quantitative assessment was provided for the components of the balance of groundwater, interstitial, and surface waters in the watersheds of the Lesnaya and Mukhavets rivers, taking into account the intra-annual variations in the intensity of infiltration recharge: the total long-term average value of groundwater recharge is 92.4 mm/year; the long-term average value of groundwater discharge into the rivers is 44.1; the total long-term average value of groundwater discharge through evapotranspiration is 48.3; and the long-term average intensity of water exchange between the groundwater and interstitial aquifer horizons is 14.2 mm/year.
