Latvia University of Life Sciences and Technologies has been responsible for implementation of the Agricultural Runoff Monitoring Programme in Latvia since 1995 until present. Water quality and quantity monitoring activities are carried out continuously in the catchment areas with high share of agricultural land at multiple spatial scales including groundwater (20 wells), experimental plots (1...

Maintenance and renovation of the drainage network is carried out to ensure the functionality of the drainage system – to preserve high-quality forest stands, as well as provide safe access to forest resources. Nevertheless, the water quality of related waterbodies may be affected because of erosion during drainage network maintenance (DNM) operations. Therefore, water protection structures...

16. Year-to-year meteorological variability is amplified in the hydrological response of the peat soils (16)

Soil water regime along with nutrient supply is controlling the forest type and its productivity. Generally, increased water supply leads to prolonged periods of soil water logging and poor soil aeration that in turn inhibit successful development of most temperate tree species.

In this study we configurated a Hydrus-1D soil water model for each of three specific wet forest plots in...

Short talks (5min)

Monitoring activities are essential to access long-term patterns in the quantity and quality of the agricultural runoff. The monitoring data on runoff in the Berze, Mellupite, and Vienziemite monitoring sites, were obtained within the Agricultural Runoff Monitoring Programme, which is determined by The Environmental Protection Strategy and carried out by the Department of Environmental...
