Water quality of many rivers in the developing countries is under serious threat of degradation and Pakistan is no exception to this. The river water may be polluted by the effluents stemming from industrial, municipal, agricultural or mining activities. The most affected rivers are those flowing through the urbanized areas and subjected to anthropogenic activities. The River Chenab traverses near the industrial cities and municipalities in the Punjab province of Pakistan. The river is largely used for constant disposal of untreated effluents in unsustainable manner. This book provides spatial and temporal trends of the river water quality based on the results of a comprehensive monitoring program. Hydrological low flow analysis is performed using long term flow time-series. The water quality indexing technique is applied for objective presentation of the data on water quality. Spatial profiles of water quality are developed with MIKE 11 model. Various scenarios are tested with the numerical model to develop strategies for water quality management. The analysis may be helpful to professionals, engineers and policy makers in environment and water resources fields.
