Upstream Flow

Water authorities apply a diversity of models and input data to set water quality-based emission limits in discharge permits. To illustrate the consequences of model and data selection, two complete mixing models and four mixing zone models used in Germany, the United Kingdom (UK), the Netherlands and the United States of America (USA) were selected and applied to various discharges of cadmium. The maximum allowable annual cadmium load was calculated for each model and diverging input data for upstream flow, upstream concentration, effluent flow and effluent concentration. Due to model selection, differences in pollutant loads amounted to a factor 3. Harmonisation of the derivation of water quality-based emission limits is necessary to prevent widely divergent pollutant loads under comparable environmental conditions.

Modelling Of Water Quality

This paper presents a one-dimensional dynamic water-quality model suitable for long-term application to estuaries. The computation techniques used in the model are very simple, but very good results have been obtained both for theoretical test cases and from applications to estuaries when compared with prototype measurements.

Modelling Approach

A water quality model has been developed with the objective of describing the water quality processes in sewer systems. The model has the capability of simulating both dissolved and sediment attached pollutants. This paper describes the modelling approach for the water quality processes and it demonstrates a small application of the water quality model to a gravity sewer operating under aerobic conditions. The application shows that the transport of dissolved substances in sewers can be accurately described and that the water quality processes are simulated with acceptable results.
