“…As a result, the above-described geological and geomorphological conditions of the catchment area of individual peatlands in conjunction with selected climatic parameters (Tomczyk, Bednorz 2022) are responsible for the spatial differentiation of river runoff seasonality (Jokiel, Tomalski 2015) and are confirmed by the research of Andrzejewski et al (2018) on the role of inland runoff and surface runoff in the circulation of matter. Geomorphological research to date suggests that the postglacial circulation of matter in the study area was strongly differentiated, as it concerned subenvironments of not only fluvial (Starkel 1997;Turkowska 1997), slope (Dzieduszyńska et al 2020) and aeolian character (Goździk 1991;Manikowska 1995) but also watershed zones with locally varied post-Saalian relief (Majecka et al 2018).…”

The chemical composition of lake and mire sediments can be used as proxies of past changes in different accumulation environments. Here, I present these proxies that can be used to reconstruct the palaeoenvironment of the past 16,000 years for many mineral-biogenic series from central Poland and establish regional similarities and differences. Past geochemical studies of biogenic sediments from this region were usually carried out in the context of the genesis of: individual accumulation reservoirs, the development of the relief of river valleys and watersheds; they were also used in combination with other methods of palaeoecological research also reconstruct climatic changes in individual phases of the Late Glacial and Holocene. However, due to the complexity of matter circulation in the lithological and hypsometrical diverse transitional zone between the belts of the Polish Uplands and the Polish Lowlands, an analysis was made to determine the relationship between the conditions of biogenic sedimentation at individual sites using selected statistical analyses. In addition to its description of the geochemical variability of biogenic sediments, this analysis was supplemented by its reference to the spatial differentiation in the relationships between geochemical landscapes and the landforms of various orders. In turn, the method of lithogeochemical facies used for several profiles along the transect from the west to the east of the region made it possible to determine: the origin of water supplying the studied biogenic accumulation reservoirs, the range of individual zones of their supply and the conditions of inflow of allochthonous mineral matter.

“…In 1970, C. G. Markham proposed a tool for assessing the many-year variability of precipitation in the United States [21][22]. Markham's seasonality measures are also used in the seasonality studies of hydrological variables such as river runoff [10,[23][24][25], physicochemical properties of surface and underground water [26], fluctuations of the groundwater [27], changes in the volume of deficits in low wages [19,28], and less changes in the volume of floods [18].…”

Nowadays, under increasing climate change effects on the environment, we can observe increasing number of extreme phenomena, including meteorological and hydrological ones. One of such phenomena are floods. The objective of this article is the assessment of basic flood characteristics seasonality in the annual distribution. Analysis were performed based on time series of daily flow values recorded in the years 1951-2014 in three gauging stations located on rivers in Easter Poland, in upper Wieprz catchment. Floods were defined according to TLM algorithm and were assumed to be all cases of flow occurrence exceeding 10% read from FDC (flow duration curve) (Q 10 ). Seasonality was analysed using Markham's Seasonality Index and Period of Seasonal Concentration, analysis of autocorrelation function (ACF) as well as proposed by the author Seasonal Winter Floods Index. The distribution of floods during year indicates one flood season in year which occurs in the spring.

“…Its variability depends on the physical and geographical conditions, in particular on the climate, morphology, geological structure, land cover and the method and intensity of the catchment management [13,14]. It is assumed that the largest transport of dissolved substances occurs during freshets caused by snow melting or rainfall.…”

Abstract. The research on the quality of the water of a small watercourse was conducted in the agricultural catchment in north-eastern Poland. The water quality was analyzed in the hydrological year and in the period of increased discharge, which in these hydro-meteorological conditions occurs in the snowmelt period. Nutrients get from agricultural land to surface water during the snowmelt or precipitation period. Therefore, the chemical composition of the water of the studied watercourse was subject to intense seasonal fluctuations. The concentration of nitrates, phosphates and ammonium ions increased with discharge. The snowmelt lasted for several days. However, as research has shown, this is a critical period for the quality of surface water in the agricultural landscape. During this period, the water of a small watercourse transported about 36% of annual nitrate load, over 45% of phosphate load and as much as 66% of ammonium ions.
