The river is the consequential landscape ? forming element as it is rinsing and transporting the weakest rocks, scraping the bed and accumulating the sediment. During these processes in the river, diverse ecosystems are forming in various areas that provide habitats for a wide range of plant and animal species. In almost every river there is occurring a natural process as erosion. River erosion assessment should be considered in river management and included in management measures, as erosion can be determining fa...

Nitrous oxide N2O is one of the major contributors to global warming and ozone depletion in the stratosphere. Management of agricultural soils is the largest source of N2O emissions in agricultural sector, therefore simultaneous and accurate measurement of N2O concentration is necessary. Nitrous oxide emission is formed within nitrification and denitrification processes in agricultural soils. The agricultural sector is one of the largest sources of greenhouse gas emissions in Latvia as it accounted for 24.6 % of t...

As a result of increasing concentrations of total nitrogen and total phosphorus, surface water chemical pollution and eutrophication is a problem of raising concern worldwide. Chemical quality of surface water gives an impression about different geochemical, geological, hydrological and biological processes, as well as intensity of anthropogenic load in river catchment area. The total length of Svete River is 123 kilometres, of which 75 kilometres are in the territory of Latvia. Main part of river?s drainage basin...
