“…Both advective and dispersive transports are considered in the materials balance. The model uses a finite-difference solution of the mass transport and reaction equations and it specifically uses a special steady-state implementation of an implicit backward difference numerical scheme, which gives the model an unconditional stability [17]. In each compartment, the model computes the major interactions between up to 15 state variables.…”

The review discusses six major public domain water quality models currently available for rivers and streams. These major models, which differ greatly in terms of processes they represent, data inputs requirements, assumptions, modeling capability, their strengths and weaknesses, could yield useful results if appropriately selected for the desired purposes. The public domain models, which are most suitable for simulating dissolved oxygen along rivers and streams, chosen in this review are simulation catchment (SIMCAT), temporal overall model for catchments (TOM-CAT), QUAL2Kw, QUAL2EU, water quality analysis simulation program (WASP7), and quality simulation along rivers (QUASAR). Each of these models is described based on a consistent set of criteria-conceptualization, processes, input data, model capability, limitations, model strengths, and its application. The results revealed that SIMCAT and TOMCAT are over-simplistic but useful to quickly assess impact of point sources. The QUAL2Kw has provision for conversion of algal death to carbonaceous biochemical oxygen demand (CBOD) and thus more appropriate than QUAL2EU, where macrophytes play an important interaction. The extensive requirement of data in WASP7 and QUASAR is difficult to justify the time and costs required to set up these complex models. Thus, a single model could not serve all wide range of functionalities required. The choice of a model depends upon availability of time, financial cost and a specific application. This review may help to choose appropriate model for a particular water quality problem.

“…This is largely because of their inappropriate treatment of advection. Although important ad- implicit differencing in time improves stability, of course, but this does not engender any improvement in accuracy at time steps significantly larger than the stability limit of explicit schemes [Walton and Webb, 1994;Manson and Wallis, 1997].…”

“…The main issue is how to use QUAL2E, a steady-state model, to assess the impact of the CSO on the receiving water. Similar concerns have been pointed out in a recent study on the Charles River in Boston (Walton and Webb, 1994). The first simulations were run on the bacteriology.…”
