Water Quality Model

The existing tools to carry out an IWRM may include hydraulic and hydrological models, water quality models as well as knowledge bases containing the necessary knowledge for the optimal management of water resources. Besides, these tools...

His 40+ publications have dealt with biogeochemical processes that control the alkalinity of surface waters, the geochemisty of dilute seepage lakes, sediment chemistry, the interpretation of water-quality trends, regional analysis of water quality, modeling lake eutrophication, lake management, reservoir water quality, and nonpoint source pollution. He recently joined the faculty of the Department of Civil Engineering at Arizona State University.

Ohio River Division perform a variety of computer assisted tasks in assessing water quality and providing input to water management decisions. These include developing and running sophisticated water quality models evaluating water quality data and operating an automated water quality laboratory. 

In the lab, future expansion plans include the use of optical scanners for reading sample labels, operation of robots to relieve some of the manual operations and an artificial intelligence system to track quality control. In other areas, there will be an increase in the number of real time monitors, not necessarily because real time data is needed, but the cost can be small compared to sending out a field team. There will be some applications of direct monitoring by satellites such as LANDSAT D. Both of these will be incorporated into water quality models which will allow more intelligent choices of where to send a field team to collect samples for detailed analysis.

From a water quality point of view, the basic relationship between waste load input and the resulting response is given by a mathematical model of the water system. The development and applications of such a water quality model in the specific context of a WLA involve a variety of considerations, including the specifications of parameters and model conditions. 

Thomann and Mueller, Principles of Surface Water Quality Modeling and Control, Harper Collins, 1987, provides other approaches in solving this type of problem. 

Thomann and Mueller Principles of Surface Water Quality Modelling and Control, Harper Row, 1987) have provided simple, easy-to-use equations that can be employed to describe the concentrations of species in different bodies of water for (a large number of) various conditions. For the case of a steady continuous discharge of a pollutant species into a lake or reservoir undergoing an irreversible first-order reaction, they have shown that the concentration of the pollutant can be described by the following equation... 

Thomann and Mueller s work Principles of Surface Water Quality Modelling and Control, Harper Row, 1987) is an exceptionally informative and well-written text/reference book that is presented in a clear, concise manner. A significant amount of information is provided for describing the fate of pollutant species in oceans, rivers, lakes, etc.
