PC-QUASAR is a water quality and flow model for river networks. It is designed for river regulatory authorities and water/sewerage utility companies to help manage river water quality. The software is no longer supported by CEH but is available to be downloaded at no charge**.
PC-QUASAR can provide distributions of flow and quality at key sites. This allows river regulators to set effluent consent levels 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. This information can then assess proposed changes in the river's use, flow or quality.
It can model the following determinands:
- river flow
- E. coli
- biochemical oxygen demand (BOD)
- dissolved oxygen (DO)
- conservative pollutant or tracer
The PC-QUASAR software is available to download free of charge. It is unsupported apart from the manual provided.
** PC-QUASAR is a 16-bit application that will not run under Windows 7 or later versions. While it may be possible to run PC-QUASAR using a Windows XP emulator or on a virtual PC, CEH offers no recommendation, guidance or support for this.
PC-QUASAR's functionality is similar to the VAX package QUASAR.
