Hydrodynamic characteristics of the groundwater source "Kljuc" of the city of Pozarevac

Abstract

Geological and hydrogeological research conducted in the area of groundwater source "Kljuc" of the city of Pozarevac aimed primarily for determining the groundwater's balance amd reserves. The study groundwater source is used for water supply of about 55 000 inhabitants in the Branicevo district, with a total capacity of approximately 250 l/s. As part of the applied field hydrogeological methods in the study area, by its significance the method of Step-Test pumping, can be singled out. The data from the groundwater source obtained in this way were processed by graphoanalytical method of processing experimental pumping data in transient flow regime, ie application of Theiss solution of differential flow to define hydraulic parameters of well (hydraulic losses in well and filter zone), filtration parameters of the medium and maximum allowed capacities of the well. Hydraulic losses that occur mainly indicate the aging process of wells which usually results in a decrease in their capacity.
