PC-QUASAR
PC-QUASAR is a water quality and flow model for river networks. It is designed to be used by river regulatory authorities and water/sewerage utility companies to help manage river water quality. The software is now available to be downloaded at no charge, as it is no longer supported by CEH (see below).
PC-QUASAR can provide distributions of flow and quality at key sites, allowing river regulators to set effluent consent levels designed to meet river quality objectives. PC-QUASAR can also provide river flow and water quality estimates at each reach boundary over a period of time, allowing proposed changes in the river's use, flow or quality to be assessed.
The following determinands can be modelled:
- river flow
- pH
- nitrate
- temperature
- E.coli
- biochemical oxygen demand
- dissolved oxygen
- conservative pollutant or tracer
PC-QUASAR software leaflet was published with the software. It is available here in the Adobe Acrobat Portable Document Format. (Note that the Institute of Hydrology is now part of CEH.)
The PC-QUASAR software is available here to download. It is free of charge and unsupported, apart from the manual provided.
PC-QUASAR's functionality is similar to the VAX package QUASAR.
