Effect of Land Use, Seasonality, and Hydrometeorological Conditions on the K Concentration-Discharge Relationship During Different Types of Floods in Carpathian Foothills Catchments (Poland).

The purpose of the study was to determine the role of land use, seasonality, and hydrometeorological conditions on the relationship between stream water potassium (K) concentration and discharge during different types of floods-short- and long-duration rainfall floods as well as snowmelt floods on frozen and thawed soils. The research was conducted in small catchments (agricultural, woodland, mixed-use) in the Carpathian Foothills (Poland). In the woodland catchment, lower K concentrations were noted for each given specific runoff value for summer rainfall floods versus snowmelt floods (seasonal effect).
