In this study, a mathematical modeling tool that can not only estimate the water quality in terms of diffuse nutrient emissions but also can track the individual impacts of each pressure (such as the boundary conditions, point sources on different locations and emissions of diffuse nutrient that reach the system at different locations and from different land use practices) is developed. The tool is based on the analytical solution of mass balance equations, so when applying the tool solutions are obtained as mathematical functions that can represent any sub-result separately from the others rather than table solutions that only give the total impact of all impacted discharges providing a spatial differentiation within the system only. The modelling tool developed and described in this study can be used to assess the eutrophication at any location in a river basin that consists of many flowing and standing waterbodies without losing the information related to each individual impact of different pressures.
