Throughout the book, the text emphasises problem-solving in which students are encouraged to apply their conceptual understanding in order to solve practical problems.
This book is primarily intended for the undergraduate students of civil engineering and agricultural engineering.
The book introduces the engineering hydrology of arid and semi-arid regions, covering meteorological processes and hydrology. The author discusses precipitation and precipitation losses, catchment characteristics, and runoff estimation methods. He also examines streamflow measurements and hydrographs, flood routing, and groundwater hydrology, including the basic equations of groundwater flow and analytic solutions describing flow aquifers, pumping tests, and salt water intrusion. Building on this foundation, the book then delineates sediment yield in watersheds and streams and the design of hydraulic structures for protection and management of water resources systems. It includes case studies, conversion tables, and modeling software.
During the last two decades, research efforts and networking have enhanced the state of knowledge about arid and semi-arid areas, especially watershed and catchment systems. Pulling this information together into a comprehensive resource, this book provides a better understanding of wadi hydrology, capacity-building processes, water education and training, and institutional development. This understanding can then be used to select the appropriate tools to support water management and optimize the sustainable use of water resources.

Proprietary and open source software (OSS) licensing represent the two extreme ends of the spectrum that could be used to build the business model of a software product. Given the changed face of the software product industry, successful software product vendors are innovating their business models by adopting a variety of combinations of these unilateral and new business models. However, these innovations also pose a number of challenges. The book examines these challenges in the context of several software product case studies in which companies successfully (or in some cases, less successfully) met these challenges and changed their business models.
Focusing on the major issues related to business models in the software product industry, the book is targeted for a variety of readers: software entrepreneurs/start-ups, software product industry professionals, academics and students. Though the industry and technologies are changing rapidly, the issues addressed here are fundamental and will remain important ones for the foreseeable future.
