Opis:
The experience of flooding from 2010 in the Commune of Spytkowice showed a dire need to define the factors behind the floods repeating every year in the region and to propose the best solutions for eliminating or limiting damage in the risk area. On account of the catchment’s location in mountainous area, the main intention was to propose actions that would mainly increase the catchment retention capacity in the upper reach of the Skawa river and its tributary, Pożoga. By slowing down the flow, these actions may considerably contribute to the protection of the most flood-sensitive areas located in the lower part of the catchment. Two solutions have been proposed based on the idea of building dry water reservoirs and providing the possibility to resettle inhabitants from the flooded area. The choice of the best solution for the Commune of Spytkowice depends on the topography of the valleys of rivers Skawa and Pożoga, as well as the financial situation concerning the project.

Opis:
In Polish hydrology and water management the term characteristic flow exists denoting a specific value of flow at the given cross-section of a river calculated as the long-term minimum, mean, median or maximum calculated using the annual minimum, mean, median or maximum flow taken for each year from a series of (usually) daily flows. Some of these characteristic flows are used to define the low-flow (o drought) periods while the another criterion: a percentage flow Qp taken from the long-term flow duration curve is also widely used. In the paper the study on the frequency structure the empirical exceedance probability of a given characteristic flow made for some low and average characteristic flows (SNQ, WNQ, NSQ and SSQ) is presented. The results show that the exceedance probability of a given characteristic flow is variable, and the amount of this variability may be large, as is the case of WNQ and NSQ. So assigning a characteristic flow to a single FDC quantile value Qp (as can be find in the literature) cannot be justified. Correlation analysis made for the pairs (P. , characteristic flow), ( P., catchment area) and (P. , gauging station elevation) revealed some significant correlations. Only for SNQ is not correlated at all; correlation for other characteristic flows is statistically significant for at least one of the cases. The highest correlations (greater than 0.4 in absolute values) were found for the pairs ( P, gauging station elevation) for NSQ and, for SSQ, ( P, SSQ) and ( P, catchment area).
