Role of Sediment Transport in Operation and Maintenance of Supply and Demand Based Irrigation Canals: Application to Machai Maira Branch Canals
UNESCO-IHE PhD Thesis
This work describes the role of sediment transport in the operation and maintenance of demand-based downstream controlled irrigation canals. Sediment deposition in these irrigation canals severely affects the operation of the automatic flow control system. The book also discusses sediment transport modelling in irrigation canals. A simplified 1-D mathematical model SETRIC (SEdiment TRansport in Irrigation Canals) has been improved with the inclusion of downstream control component for the downstream controlled irrigation canals. Based on field measurements and sediment transport modelling, a number of approaches have been proposed for sediment management in such irrigation canals by improvement in their design and operation. This book will be of interest to Irrigation Engineers and Managers, Hydraulic Engineers, Water Resources Engineers and Managers, Civil Engineers, and Agricultural Engineers.
Sarfraz Munir (Narowal, Pakistan, 1974), received his Bachelor and Master degrees in Agricultural Water Management from the North Western Frontier Province (now Khyber Pakhtunkhwa) Agricultural University, Peshawar, Pakistan in 1997 and 2000 respectively. He served from 1999 to 2009 in the International Water Management Institute (IWMI) in Pakistan. He has been engaged in a number of projects on performance assessment of irrigation systems in Pakistan, agricultural water management, environmental impact assessment of wastewater irrigation and the evaluation of modernized irrigation systems. His assignments included field measurements for agricultural and environmental water management like flow measurements in irrigation canals, hydraulic structures’ and downstream gauges’ calibration, longitudinal and cross-sectional surveys in irrigation canals, groundwater observations, installation of necessary equipment for surface water and groundwater observations, in situ water quality measurements, laboratory analysis of plant, soil and water quality, socio-economic surveys, hydraulic modelling, synthesis of field data and report writing. From 2006 untill 2011 he conducted his PhD study in Hydraulic Engineering-Land and Water Development Core, UNESCO-IHE, Institute for Water Education, Delft, the Netherlands.
