FUTURE CHALLENGES IN WATER QUALITY MODELLING WITH PARTICULAR REFERENCE TO OPERATIONALLY CLOSED CATCHMENTS

Abstract

As a result of the declining quality of many water sources, the use of water quality models in planning is increasing. To date applications have involved the simulation of total dissolved salts and nutrients, largely in catchments affected by urban and industrial development. Whilst such applications are certain to continue, the future problems requiring this type of analysis are likely to be far more complex. Additionally, the questions asked of modellers will become more detailed and specific.
