Hydrogeological conditions in the Botevgrad Kettle

Abstract

Groundwater in the Botеvgrad Kettle (West Bulgaria) is important for the local population. Despite the information available for this area, the catchment area of this kettle is poorly studied from a hydrogeological perspective. Therefore, the objective of this current study is to assess the hydrogeological conditions based on existing information for the purpose of better water resource utilization. Using GIS and data from the Geological Map 1:100000 and Hydrogeological Map 1:200000, water types in the Botеvgrad Kettle watershed and their spatial distribution in the area have been determined. The primary focus is on the region's most water-abundant hydrogeological unit, the Quaternary aquifer. Using various GIS layers that characterize spatial changes in hydrogeological characteristics, a conceptual model for this horizon has been developed, facilitating the initiation of activities related to numerical modeling.
