Dynamics of Stream Water Quality during Snowmelt and Rainfall - Runoff Events in a Small Agricultural Catchment

Popis výsledku v původním jazyce

This paper uses a set of hydrological and hydrochemical variables to explain concentration?discharge loops and hysteresis of N , NH4 and total suspended solids in a brook dewatering a small upland agricultural catchment in the Czech Republic. Our study is based on data collected by a continuous monitoring approach provided by an automatic ISCOsampler both fromsnow thawing and rainfall ? runoff events. Methods of correlation, regression and principal component analysis (PCA) were employed to reveal possible relationships among the variables. For NO3 and NH4 , we found several types of concentration?discharge loops due to the loop rotation direction and also the loop curvature shape, in mutual combinations, no matter which type of a hydrological event itwas related to. PCA indicated that NO3 loops correlated mostly with the length of a rising hydrograph limb and with the slope of the initial phase of a falling hydrograph limb, 5-day amount of precipitation and runoff coefficient.
