Integrated catchment modeling for nutrient reduction: Scenarios showing impacts, potential, and cost of measures

Article Abstract:

A hydrological-based model (HBV-NP) was applied on a catchment in the Southern part of Sweden and a careful characterization of the situation and potential for improved treatment or reduced soil leaching was analyzed. Several scenarios were modeled to find strategies to reach the Swedish environmental goals of reducing anthropogenic nitrogen load by 30% and phosphorus load by 20% that could be achieved by use of different approaches affecting different polluters and social sectors.

Parameter precision in the HBV-NP model and impacts on nitrogen scenario simulations in the Ronnea River, Southern Sweden

Article Abstract:

The HBV-NP model is a newly developed water quality model that describes the turnover and fluxes of both nitrogen and phosphorous. There was a reduction of nitrogen load into sea by 30% and simulated relative reduction of nitrogen load in the sea was relatively insensitive to choice of parameter set according to the input, sources, variations and data.

Estimating catchment nutrient flow with the HBV-NP model: Sensitivity to input data

Article Abstract:

The dynamic catchment model HBV-N was developed by adding routines for transport and is hence called HBV-NP that satisfactorily simulates nutrient dynamics in Ronnea catchment area. The results revealed that the increased sensitivity to the selection of input data on a subcatchment scale when it was compared with catchment scale.
