i am working on a project that models the water quality of a river/stream. kindly suggest some softwares or models for modeling the whole stretch of the river.
Dear Lakshmikanthan,
Use delft3D for water quality modelling. It is one of the best software for modelling water quality in rivers, lakes, estuaries areas, canals,...
You can also use QUAL2E or QUAL2EU.
The Enhanced Stream Water Quality Model (QUAL2E) is a steady-state model for conventional pollutants in branching streams and well mixed lakes. It can be operated either as a steady-state or dynamic model. The model is intended for use as a water quality planning tool.
The model can be used to study the impact of waste loads on instream water quality. It can also be used to identify the magnitude and quality characteristics of non-point waste loads as part of a field sampling program. The user can:
- Model effects of diurnal variations in meteorological data on water quality, primarily dissolved oxygen and temperature.
- Examine diurnal dissolved oxygen variation caused by algae growth and respiration.

Dear Lakshmikanthan,
Prof. Bachir ACHOUR has already mentioned the softwares for river/stream water quality modeling ( delft3D, QUAL2E or QUAL2EU ).
You can read the attached paper on the development of river water quality models. It is useful to understand the topic.
Best wishes
Dear Jiu,
It's good that you have provided the link. But not much discussions on the topic. Thanks
Dr. Harvey Jobson developed the Branched Lagrangian Transport Model, BLTM ( https://water.usgs.gov/software/BLTM/ ). It can simulate one dimensional branched streams under transient conditions and avoids most numerical dispersion. We used BLTM to model DO for the purpose of developing TMDLs. Some familiarity with FORTRAN may be needed to run or adapt the model. You might find it to be a useful alternative depending on your goals and constraints. Here is a link to a conference paper on our application: Conference Paper Lagrangian Water Quality Modeling and TMDL Development in Lo...
Dr. Michael Waldon,
Branched Lagrangian Transport Model, BLTM - Yes, it may be an alternative way. Thanks and regards
Dear Lakshmikanthan,
i suggest you to use qual2kw, mike11 and mike 21

You can check out DESCAR.
M also giving you a link of WASP where you can explore few modelling

Furthermore EPA models, MIKE hydro River, MIKE eco lab, and MIKE 21, etc powered by DHI are friendly and powerful entonces for modelling Walter quality
I would suggest SWAT ( The Soil & Water Assessment Tool ) developed at TEXAS A&M UNIVERSITY if you're working on a watershed.
The Soil & Water Assessment Tool is a small watershed to river basin-scale model used to simulate the quality and quantity of surface and ground water and predict the environmental impact of land use, land management practices, and climate change. SWAT is widely used in assessing soil erosion prevention and control, non-point source pollution control and regional management in watersheds.
I know your question has been around for a long time, but I would still like to contribute. I used the QUAL2E model in my master's study, developed in the Amazon, and had excellent results. Today QUAL2K is also widely used. I suggest you research it.
Six main public domain water quality models which are presently available for Rivers and streams are being captured in this article. These main models could produce important results if they are used in the correct manner, because they are different in terms of assumptions, strength and weaknesses, processes they represent, modeling capability and data input requirements. The Model review discussed includes, water quality analysis simulation program (WASP7), simulation catchment (SIMCAT), quality simulation along Rivers (QUASAR), and the temporal overall model for catchment (TOMCAT), QUAL2KW, QUAL2EU. The models are described individually according to a consistent set of criteria-conceptualization, model capability, model strengths, limitations, input data and how it utilized. The outcome showed that TOMCAT and SIMCAT are important in ASSESSING effect of point sources in a very simple way. The QUAL2KW, unlike the QUAL2EU where macrophytes play a major interaction, it can convert algal death to carbonaceous Biochemical Oxygen Demand (CBOD), thereby making it more suitable. In addition to the extensive requirement of data, it is expensive and time consuming to set up these complex models such as QUASAR and WASP7. Therefore, one model cannot be used for all the required functionalities. Choosing a model would depend on a specific application, financial cost and time availability. This article may be of help in choosing a suitable model for a specific water quality problem.
