Determination of theoretical flood waves, commonly known as hypothetical waves, is still a difficult problem to be solved. Most frequently hydrological modelling is used for this purpose. However, there are no methods for verifying the obtained calculation results. The assumption applied, that daily precipitation with a defined height difference probability triggers off a theoretical wave with the same probability of excess, was verified in four upland basins whose river mouths are located within Kraków metropolitan area. It was proved that in order to meet the assumption made, it is necessary for the precipitation duration, with defined height difference probability, to last 48 hours, because for daily precipitation the volume of calculated theoretical flood wave is too small. During the calculations, the hydrological model was used, as was the formula for flood wave volume determination for the area of Upper Vistula River, as developed by the main author of the publication. The relative error of the reduced volumes in relation to the volumes calculated with the Kraków method for theoretical flood waves, was lower than 30% in any case. Therefore, it can be acknowledged that the suggested method may be used for determining theoretical flood waves in any cross-section for the non-gauged catchment with a surface not exceeding 400 km².

The Dobczyce Reservoir is one of the new man-made lakes located at the Raba River in the Carpath-ian Mountains. The drainage basin is underlain by flysch with a high proportion of sandstone. The river is characterized by great variability of runoff. The mean annual discharge is about 12 m3·s-1. The dam began to function in 1986 and about 2.1 m3·s-1 of fresh water has been withdrawn from the reservoir to Cracow. The model was calculated for estimating Raba River discharge down the reservoir. Analysis of the river discharge before and after the dam construction has shown that one of the most important effects of the Dobczyce Reservoir is a change of the Raba River runoff: mean minimum and maximum monthly dis-charges increased and mean monthly discharge decreased.

The paper treats on hydrological distributed model adaptation for a catchment with significant contribution of wetland. The WetSpa model was applied to analyzing the effects of topography, soil type, and land use cover on the runoff characteristics for upper Biebrza catchment. The derivation of parameter maps and analysis of the daily runoff as reaction of the catchment on rainfall was performed. The semi-automated calibration of the model was executed using PEST module. Then, the assessment of that crucial processes was done by calculating errors of mathematical models performance as well as hydrograph comparison. Error values, have shown that the model efficiency was estimated to be good for high flows, but unsatisfactory for low flows. This initial modeling approach gives possibility to ask question about limitation and needs of wetland catchment for rainfall-runoff modeling.

W pracy przedstawiono wyniki obliczeń wielkości spływu powierzchniowego z wykorzystaniem jednowymiarowych modeli infiltracji Green-Ampta, Diskina-Nazimowa oraz metodą NRCS-CN. W celu weryfikacji poprawności zastosowanych metod obliczeniowych wyniki obliczeń porównano z pomiarami spływu powierzchniowego z dwóch zdarzeń opadowych zarejestrowanych na jednym z poletek doświadczalnych Stacji Naukowo--Badawczej Instytutu Geografii i Przestrzennego Zagospodarowania Polskiej Akademii Nauk w Szymbarku k. Gorlic (Beskid Niski). Wyniki obliczeń wykazały, że model Green-Ampta dał najbardziej zbliżone wyniki obliczeń do danych pomiarowych. Nieco gorsze wyniki obliczeń uzyskano z modelu Diskina-Nazimowa, przy czym model ten dał wyniki porównywalne do danych pomiarowych w przypadku drugiego zdarzenia opadowego charakteryzującego się znaczną intensywnością, a zaniżał wyraźnie wielkość spływu w przypadku pierwszego zdarzenia opadowego. Natomiast wyniki obliczeń otrzymane z modelu NRCS-CN wykazały znaczną rozbieżność w stosunku do wyników pomiarów, co wskazuje, że model ten wymaga kalibracji uwzględniającej warunki klimatyczne naszego kraju.
