ABSTRACT
The paper presents the results of the estimation of the runoff formation during floods events in the upper Bóbr River basin, including its left-sided tributary the Kwisa River. The analysis was carried out on the basis of historical maximum freshets recorded at 15 gauging stations located on the streams and rivers in the investigated area in multiyear 1970–2004. For all standardized freshets the basic parameters were determined: reduced maximum discharge, duration times and volumes for wave phases, rising and falling and for total wave. On the basis of these parameters the regional relationships of maximum outflow were determined for the Bóbr River basin. The obtained results are satisfactory, most of the relationships proved strong correlations, confirmed by high values of determination coefficients. Determined regional relations between the waves’ parameters give a view on the course of flood events and the maximum outflow formation in the basin and can be useful in engineering issues in the studied region.
