Abstract

This study presents changes in water conditions in the Lublin agglomeration, especiallyas regards discharges from the Bystrzyca and other rivers. Areas covered with impermeable materials,such as asphalt and concrete, have caused changes in directions of surface runoff and an intensifi cationof this process, with effects on the discharges of rivers. The regime of fl ooding is the consequence ofnatural and anthropogenic conditions. Spring and summer fl oods in Lublin and at water gauges belowthe city are mainly caused by surface runoff from the urban area. During periods of snowmelt periods ortorrential rain, water fl ows rapidly through the system of stormwater drainage, and then into the rivers.

Keywords: anthropopressure, river discharges, fl oods
