Abstract

Nutrient sources and fate are investigated in the Evrotas, a temporary river in Greece. We assess field monitoring and modelling tools for the estimation of nutrient fate and transport through various diffuse pathways. The ‘total daily maximum load’ approach is used to estimate the nutrient flux status by flow class and measures are recommended and applied for each flow status. Using this approach in Evrotas basin, it was estimated that almost 60% of the river network fails to meet nitrogen criteria and 50% phosphate criteria. We recommend that existing well-documented remediation measures such as reforestation of the riparian area should be implemented to achieve load reduction in close conjunction with social needs.
