A practical approach to river water quality modeling

Water Quality Modeling (WQM) is an integral part of watershed management in Malaysia as well as many other countries in the world. They are employed for various purposes, such as impact assessment due to development, river rehabilitation studies as well as non-point source pollution characterization...

This book does not aim to discuss the underlying mathematical formulations of QUAL2E nor QUAL2K, as the respective developers have developed sufficient user manuals, which deal with these aspects.
