Opis:
The aim of this study was to analyze the dynamics of groundwater level and water reserves changes in the active layer of the soil in the area of compensation activities. The study area covered the range of functioning culverts during the growing season in year of 2012. This paper for the first time presents a real area impact of hydraulic structures which is the surface of the flood footprint that arise as a result of water overflow into the polder from Warta river by culverts. According to the calculation the maximum coverage area of the building is less than 230 ha. It is not so much considering the fact that the whole area of the polder has almost 1200 hectares. Nevertheless, considering the fact of the importance of leading restoration activities in the Central Valley Warta the constant monitoring and verifications of changes are required. At this work relations between underwater level and water supply were presented. For that purpose a statistical relation between above mentioned parameters was determined. Using a simple regression equation the relationship between ground water and water reserves was showed. In addition, the changes of groundwater level and soil moisture of polder Zagorow were assessed against the monthly precipitation and average air temperatures by their own weather station. The results were compared with data from multiple years of 1981–2011 with a weather station in Slupca. On the basis of measurement average daily values of meteorological elements indicate reference evapotranspiration by using method of Penman-Monteith. Climatic water balance was calculated as the difference between the percentage of monthly precipitation P and the sum of the monthly reference evapotranspiration ETo. In addition, the study also monitored the level of water changes on the Warta river. Modeling studies conducted, in most cases gave satisfactory results. In most of the analyzed cases, the coefficient of determination was very high which means that the resulting regression equation significantly explains how the water reserves to groundwater level dependent. Best results are obtained at positions 1, 2 and 9, where more than 90% variation in the regression equation Y explained. Only in sections 4 and 5 shows the model inadequately describes the relationship test. In case of further analysis it is necessary to extend the model to a further independent variables. In this work, we can see that for some positions a major impact on the level of water reserves are influenced by the meteorological and hydrological conditions.

Opis:
The paper presents an assessment of changes in water resources in the areas of two polders – Nielęgowo and Zagórów – located in the Wielkopolska region. Changes in water relations of the surveyed valley areas were analyzed on the basis of the position of groundwater table and water supplies in the top layer of soil. Detailed analysis of the results of measurements carried out in two in terms of wet, dry, and growing seasons of 2008 and 2012 showed a difference of stocks in the upper layers of soil moisture of valley areas. Changes of water backup and groundwater levels were associated with the course and distribution of precipitation in the analyzed periods of vegetation. In Zagórów polder the amount of precipitation in the winter half-year, preceding the analyzed vegetation period of 2012, has also affected the size of the water supply and the state of groundwater. Positions located in the upper parts of Zagórów polder were characterized by the greatest amplitude of fluctuations in water table levels. However, in the positions located in the lowest points, the amplitude of the fluctuations in water level amounted to 0.9 m on average. There were also differences in the stocks of water in the upper layers of soil. The largest reserves of water were found in the lowest-lying parts of the polder, where the maximum water supplies ranged from 305 mm to 364 mm. On the basis of statistical analysis, the purpose of which was to determine the relationship between the supply of water in the top layer of soil and groundwater conditions in valley areas found that from 81% to 90% of the total variability in the water supply was dependent on the level of fluctuations in the groundwater table.
