The aim of this study was to provide the first account of fish and macroinvertebrate communities in a heavily degraded river basin in the Czech Republic. Fish and macrozoobenthos were surveyed at 18 s...
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 reservoi...
Irrigation with treated wastewater is essential for increasing crop production in arid and semi arid regions. Field experiments were conducted on rainfed clayey soil to investigate the impact of water...
The ecological status of many surface waters in the Czech Republic is poor, mainly due to still relatively high discharges of N substances especially from agriculture. High nitrate values in the strea...
This contribution arises from a broader research assignment dealing with the changes in soil properties and characteristics which have occurred following the artificial drainage of some agricultural s...
The changes in water quality caused by grassing of arable land followed by the reduction in the use of fertilisers after 1989 are demonstrated on an example of two tile-drained subcatchments in spring...
A review of the land use/water quality interface of the Great Lakes system, and the monitoring programs in place. The paper reviews the weakness in the system and suggests opportunities for improvemen...
Impervious surfaces have for many years been recognized as an indicator of the intensity of the urban environment and, with the advent of urban sprawl, they have become a key issue in habitat health. ...
