“…Forests are the predominant land use within most catchments, comprised mainly of spruce or a mixture of spruce, pine and broadleaf forest stands 27,29 , while meadows used for grazing and hay production are also prevalent. Intensive meadows can constitute as sources of eutrophication 30 , however, liquid fertilization of grasslands has been decreased or discontinued within parts of this region 31,32 . As with many other border regions within the Palearctic, this sparsely populated area has experienced a gradual recession in farming due to barren soils unsuitable for agricultural intensification 33 .…”

Land use is a predominant threat to the ecological integrity of streams and rivers. Understanding land use-water quality interactions is essential for the development and prioritization of management strategies and, thus, the improvement of water quality. Weighting schemes for land use have recently been employed as methods to advance the predictive power of empirical models, however, their performance has seldom been explored for various water quality parameters. In this work, multiple landscape composition metrics were applied within headwater catchments of Central Europe to investigate how weighting land use with certain combinations of spatial and topographic variables, while implementing alternate distance measures and functions, can influence predictions of water quality. The predictive ability of metrics was evaluated for eleven water quality parameters using linear regression. Results indicate that stream proximity, measured with Euclidean distance, in combination with slope or log-transformed flow accumulation were dominant factors affecting the concentrations of pH, total phosphorus, nitrite and orthophosphate phosphorus, whereas the unweighted land use composition was the most effective predictor of calcium, electrical conductivity, nitrates and total suspended solids. Therefore, both metrics are recommended when examining land use-water quality relationships in small, submontane catchments and should be applied according to individual water quality parameter.

Dumbrovský M., Sobotková V., Šarapatka B., Váchalová R., Pavelková Chmelová R., Váchal J. (2015): Long-term improvement in surface water quality after land consolidation in a drinking water reservoir catchment. Soil & Water Res., 10: 49-55.The aim was to explore how soil and water conservation measures, applied in the process of land consolidation, affected nutrient concentrations in surface waters of the Hubenov drinking water reservoir in the Českomoravská vrchovina Upland. A significant part of the catchment serves as a protection zone for the reservoir. The protection measures, such as restrictions on the maximum amount of manure and N and P fertilizers, were applied in the case study area according to recommendations of a land consolidation project. The Hubenov reservoir water resources were monitored for twenty years in order to collect water quality data on nitrate nitrogen (N-NO 3 -), total phosphorus (P tot ), and total suspended solids. The results of monitoring indicate a linear trend of decrease in N-NO 3 -and P tot concentrations following the soil and water conservation measures applied.
