Water Quality Simulation Model
Journal of the Sanitary Engineering Division, 1971A model for simulation of stream hydrology, water uses, and water quality is described. The model was developed to generate weekly (48 time intervals per yr) streamflow and water quality data based upon inputs of stream gage records, reservoir regulation, water uses, wastewater discharges, and other essential parametric data.

The water use locus of a river basin is its stream system. Streams are sources of water supply and, at the same time, they function as sinks for used water. Two categories of used water of interest are: (1) point source discharges of treated waste water, i.e., from municipalities and industries, and (2) non-point source flows, i.e., from irrigated ...

, 2001 This report serves as a guide to the utility and relevance of water quality prediction modeling. It draws upon examples from recent World Bank water resources and wastewater management projects. The goal of the guide is to provide a broad-based understanding of the water quality prediction process and to evaluate the relative merits and cost ...

Abstract Water-quality modelling is a very active research area and there are two distinct trends towards: (1) parallel algorithms to handle larger and larger problems; (2) adaptations of algorithms to be run on personal computers. Since this is a complicated subject all that is attempted here is a broad outline of current methods plus ...

Applications of water quality models are a required part of many local and regional decisions. The location of major industrial facilities must make use of water quality analyses. Under the Clean Water Act of 1977 (for a review of its provisions see Environmental Law Reporter, 8 ELR 10010, January, 1978), and its National Pollutant Discharge ...

After discussing some of the basic aspects of the structure of river water quality models, the dynamic equations governing the evolution of the relevant biochemical phenomena are presented. Necessarily, many important river pollution problems as well as the numerical aspects of model integration or parameter estimation are dealt with very briefly, or ...

Predictions of water quality involve the modelling both of physical processes, which underlie the transport and diffusion of all constituents, and of the sources, sinks, partitioning and interactive processes individual to those constituents.

Modeling watershed water quality
1995In recent years, a risk-based management approach to water quality protection is gaining increased popularity. This approach relies upon the identification and targeting of worst case problems as those needing initial emphasis. One of the currently available engineering tools that is believed to satisfy the greatest needs and provide the best ...
