Mathematical description of water flow quantity for microhydroelectric station

A simple flow-concentration modelling method for integrating water quality and water quantity in rivers

As part of the determination of the ecological Reserve for rivers in South Africa (National Water Act, 1998), flow requirements are assessed for maintenance low flow, drought low flow and flood conditions. Since water quantity and water quality are often closely linked, it is necessary to ensure that in setting the recommended flow regime, the appropriate water quality will be attained. This pa...

Kinetics of passive transport in water/membrane/water system. A mathematical description.

Passive transport across the lipid region of the membrane is considered to be one of the main mechanisms by which many solutes, especially xenobiotics, enter the cell (Stein 1981). Although the problem of mathematical description of the process has been intensively treated, it continues to be a subject of controversy. Some approaches do not take into account the solute accumulation in the membr...

A Meta-model for Water Quantity and Water Quality

The management of water resources requires simulation models for different time horizons and spatial scales as well as different types of information systems as GIS or Water Information Systems. Mathematical models integrate former experiences and theoretical knowledge about a system with actual information gained by natural processes and man-induced activities. Because of the great variety and...
