Thermal and snowy conditions in Zagożdżonka River catchment during hydrological years 2003–2013 and winter floods are presented in paper. The meteorological and hydrological data, such as maximum, minimum, mean diurnal air temperatures, daily snow cover depth, and water discharge, collected at Czarna station (WULS-SGGW) have been used. Meteorological conditions were analyzed using indexes proposed by Paczos. Temperate cold and extraordinarily low snowy winters has dominated in Zagożdżonka catchment in presented period of time. Winter floods as a result of snowmelt have been observed almost each year, except 2008 when winter was mild and extremely low snowy. The relation between winter severity index (WOz) and winter snowiness index (WSn) has been estimated, as well as the relation between winter snowiness index and maximum discharge (Qmax).

The paper presents the measurement results of bedload sediment transport during the flood flows observed in the Zagożdżonka River. The point for measuring the bedload transport, equipped with sediment catcher, devices for continuous measurements, and automated data recording, was localized above the Czarna gauge station in catchment studied by the Department of Hydraulic Engineering and Environmental Restoration, Warsaw University of Life Sciences – SGGW. The results of bedload transport measurements during one of the flood flow waves were compared to those calculated by using the Bagnold’s formula. To determine the critical bed-shear stress, the Author’s formula resulting from laboratory experiments, was used. Calculated variability of bedload transport rate during analyzed flood flow wave apparently differed from that directly measured. Nevertheless, mass of bedload achieved from calculations was lower by 6% than that from measurements, which can be considered as good result consistence.

The aim of the study was determination of number and species composition of entomopathogenic fungi for two river catchments: Zwolenka and Zagozdzonka. Both are left side tributaries of the Vistula River and have different geological structure. The area is dominated by mosaic of extensive agriculture and forests. Three species of entomopathogenic fungi were found: Beauveria bassiana, Metarhizium anisopliae, Isaria fumoso-rosea. The dominant species in both catchment basins was I. fumosorosea. Infections caused by other factors were also noted (48% by entomopathogenic nematodes of the family Steinernematidae, remaining 19% by mites, saprophytic fungi, non-fruiting mycelia and other unidentified factors).

In this paper, two rural catchment- the Zagożdżonka catchment in Poland and the Skuterud catchment in Aas, Akershus county in Norway are compared. In addition to the general description, more in particular information, runoff, NO3 load, P-PO4 load, total phosphorus and total nitrogen concentrations in streams are compared. The data compared are from 1993 to 1995 in Zagożdżonka catchment and from 1994- 1996 from Skuterud catchment. The average concentration of N-NO3 in Zagożdżonka River in the period was 0.85 mg•1-1 and the mean concentration of P-PO4 was 0.13 mg•l-1. In the stream in Skuterud catchment the average concentration of N-NO3 was 4.95 mg•1-1 and the mean concentration of P-PO4 was 0.04 mg•l-1. For both catchments the same data were also compared for the 2008. In Skuterud catchment the highest concentration of nutrients occurred in November, March and April, which was connected to the higher runoff from agricultural areas during the snowmelt period. In Zagożdżonka catchment the highest concentration of nutrients was noted in March, April and in summer time, which was connected to periods with high amounts of precipitation. Comparison of the two rural catchments showed many differences in applied measurement methods for water sampling, water measurement, discharge measurement, runoff amounts and management practices, which had an effect on results of monitoring program. The compared data can be useful to predict the development of future environmental conditions for example water quality. It can also be useful for predict how nutrient runoff will be in future. What is more the different conditions for runoff in Skuterud and Zagożdżonka then different measures are needed.

Rolnicza zlewnia rzeki Zagożdżonki położona jest na Nizinie Mazowieckiej, należącej do tych regionów kraju, w których najczęściej występują susze. Celem pracy jest analiza niżówek rzeki Zagożdzonki w profilu Płachy Stare w latach 1963–2007. Materiał wyjściowy do analiz stanowiły wyznaczone parametry niżówek w profilu. W celu określania okresów niżówkowych na hydrogramach dobowych przepływów zastosowano metodę polegającą na wyznaczaniu niżówek za pomocą poziomów odcięcia – SNQ i Q90%. Najdłuższa i najsurowsza pod względem deficytu odpływu była niżówka w 1964 roku. W rozpatrywanym okresie nie zaobserwowano niżówek zimowych. W ostatnich latach badanego wielolecia niżówki występują co rok, jednak ich rozmiary i intensywność nie osiągają takiego poziomu jak w wypadku niżówek z lat ubiegłych.
