Biography

Main competence on runoff, erosion and nutrient transport from agricultural land to water bodies - processes, pollution levels and mitigation measures. I contribute to developing tools and models used for e.g. evaluating needs for and efficiency of measures (Agricat 2, AGRITIL) and as a basis for e.g. subsidies (erosion risk map), and I have used these in many projects.

Abstract

This report describes the development of models to calculate losses of soil particles, phosphorus, nitrogen and organic carbon from agricultural land to first order streams. The results from the models serve as input data to the TEOTIL model which estimates the net losses from agriculture and all other sources. The agricultural models (AGRITIL) were calibrated for catchments in the Agricultural Environmental monitoring programme and are limited by the availability of data for different regions in Norway.
