The branch of informatics which deals with the application of information and communication technologies in addressing the problems related to the use of water is referred to as hydroinformatics. It primarily focuses on the problems of equitable and efficient use of water for various purposes. One of the closely related fields of hydroinformatics is computational hydraulics. Hydroinformatics primarily focuses on the numerical simulation of water flows and related processes. It makes use of the techniques of artificial intelligence such as artificial neural networks, support vector machines, etc. Hydroinformatics is a vast field which draws on various fields such as hydrology, hydraulics and environmental engineering. It is applied in urban drainage and water supply systems. This book consists of contributions made by international experts. The topics included herein on hydroinformatics are of utmost significance and bound to provide incredible insights to readers. This book will serve as a reference to a broad spectrum of readers.
