Case Study 4: Effectiveness of pollution control measures under scenarios of future climate and land cover change at the catchment scale.
Despite the uncertainty in future climate and land use, large-scale measures put in place today to improve water quality are likely to remain effective in the future in northeast Scotland. Dynamic models can provide useful indications of the likely lag time between...

INCA-N (Integrated Catchments Model - Nitrogen dynamics)
INCA-N operates at a daily time step, tracking the stores and fluxes of water, nitrate and ammonium in both the land and in-stream phases of a river catchment. The model is spatially ‘semi-distributed’: the water course is split into reaches with associated sub-catchments....

Case Study 5: Uncertainty in ecological responses to water quality control measures at the river basin scale.
QUESTOR modelling shows that all the mitigation methods applied can reduce the amount of Chlorophyll-a predicted to occur in the river. The extent of the reduction is different depending on the data used to drive the QUESTOR model. The effect of increasing the shading...
