EUROHARP-NUTRENT - Nutrient retention calculation tool

The retention of nutrients in different water body types such as streams, rivers, lakes, reservoirs and riparian wetlands is important as physical, chemical and biological processes either permanently remove nitrate through denitrification or store organic N and phosphorus for shorter or longer periods, thus delaying transport in the river basins. When analysing nutrient pressures against observed nutrient exports from river basins, knowledge on the current importance of nutrient retention is demanded (from the downloadable EUROHARP Retention Handbook).
