A combined statistical approach for evaluation of the effects of land use, agricultural and urban activities on stream water chemistry in small tile-drained catchments of south Bohemia, Czech Republic
Original language description
This work evaluates the changes of nitrate-nitrogen (NO3-N), ammonium-nitrogen (NH4-N), Total Phosphorus (P) and Chemical Oxygen Demand (COD) concentrations in stream waters as related to the land use/land cover (LULC) alterations within eight small (5?39 km2) tile drained catchments in the southern part of the Czech Republic in the period 1993?2010, when massive grassing of arable land took place. The robust tools of seasonal Mann-Kendall trend test and LOcally WEighted Scatterplot Smoothing (LOWESS) methods were employed to reveal trends of the monitored parameters with adjustment to hydrology. Using principal component analysis (PCA) and multiple regressions, statistically significant factors with highest impacts on the assessed water quality parameters were identified. Beside indicators of LULC changes in the catchments and their various zones, information of built tile drainage systems were used along with factors reflecting point pollution sources such as the population number, s
