Mousetrap: modelling of water quality processes and the interaction of sediments and pollutants in sewers

Abstract

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.

The sources, impact and management of car park runoff pollution: A review

“…This has led to the development of deterministic algorithms based on sediment transport theory (Price and Mance, 1978;Sonnen, 1980) and their incorporation into models such as MOSQITO (Payne et al, 1990), MouseTrap (Garsdal et al, 1995) and HydroWorks(TM) (David and Matos, 2002), where surface solids are removed by a combination of raindrop impact and overland flow. The removal potentials of other pollutants are then estimated as a fraction of the sediment mass discharged through the application of "potency factors".…”

Modelling, Simulation and Control of Urban Wastewater Systems

“…The model developed, called MOUSETRAP, simulates the parameters DO, BOD, COD (as dissolved and sediment-attached parts), ammonia, nitrogen, phosphorus, non-uniform sediments, three types of bacteria and user-specified metals. More details on MOUSETRAP are described by Mark et al (1993Mark et al ( , 1996Mark et al ( , 1998, Crabtree et al (1994bCrabtree et al ( , 1995, Gustafsson et al (1994), Appelgren et al (1995), Garsdal et al (1995). According to Appelgren and Hemebring (1994), their application of MOUSETRAP for the Rya catchment in Goteborg was the first attempt to use a deterministic modelling approach of sediment transport on real catchment data.…”

Prioritizing Subwatersheds for Stormwater Pollution to Wachusett Reservoir

“…Stormwater modeling is also important for developing effective stormwater management strategies in target watersheds. Previous studies have employed stormwater modeling to assess and predict stormwater pollution (Sartor and Boyd, 1972;Shaw, 1994;Garsdal et al, 1995;Wong et al, 1997;Chiew and McMahon 1999;Beven and Freer, 2001;Ackerman and Schiff, 2003;Doherty and Johnston, 2003;Kanso et al, 2003;Park and Stenstrom, 2007;Park et al, 2009). Because urbanization increases runoff volume and degrades water quality, many studies have focused on modeling urbanized areas by applying an overland process (i.e., buildup and wash-off module) and sewer processes (Sartor and Boyd, 1972;Garsdal et al, 1995;Shaw, 1994;Kanso et al;Obropta and Kardos, 2007).…”
