A Water Resources Engineering eBook has been posted as a series of PDF files by the Indian Institute of Technology (IIT) at Kharagpur. This is one in a series as part of an effort known as the National Programme on Technology Enhanced Learning (NPTel).
"The main objective of NPTEL program is to enhance the quality of engineering education in the country by developing curriculum based video and web courses. This is being carried out by seven IITs and IISc Bangalore as a collaborative project. In the first phase of the project, supplementary content for 129 web courses in engineering/science and humanities have been developed. Each course contains materials that can be covered in depth in 40 or more lecture hours. In addition, 110 courses have been developed in video format, with each course comprising of approximately 40 or more one-hour lectures. In the next phase other premier institutions are also likely to participate in content creation."
