A review of modelling tools for implementation of the EU Water Framework Directive in handling diffuse water pollution
A numerical catchment-scale model capable of simulating diffuse water
pollution is necessary in sustainable environmental management for better implementation
of the EU Water Framework Directive. This paper provides critical
reviews of most popular and free models for diffuse water modelling, with detailed
sources and application potential. Based upon these reviews, further work
of selecting and testing the HSPF model was carried out, with a case study in
the Upper Bann Catchment, Northern Ireland. The calibrated and validated HSPF
model can well represent the characteristics of surface water quantity and quality.
Climate change scenario evaluation in 5 years showed that when the annual mean
temperature increase 3◦C the mean yearly total runoff volume will decrease by 11.1%
and the mean daily river flow 11.4%. If 20% crop and pasture land is converted into
forest land in the study area, the mean river concentration of nitrate, nitrite, NH4
and PO4 in 5 years will decrease by 19.4%, 33.3%, 31.3% and 31.3% respectively.
When applying filter strip method in 80% crop and pasture land in the area, the
reduction of the mean concentration of nitrate, nitrite, NH4 and PO4 in 5 years will
be 15.3%, 33.3%, 31.3%, and 5.6% respectively. This study shows that HSPF is a
suitable model in handling diffuse source water pollution, which can be introduced into the Programme of Measures in the River Basin Management Plans for better
implementation of the EUWFD
