The application of information and communications technologies in order to address the crucial problems of the efficient use of water falls under the domain of hydroinformatics. It uses techniques such as artificial neural networks, support vector machines and genetic programming. It primarily integrates the concepts of hydraulics, hydrology and environmental engineering. Hydroinformatics lays emphasis on the social nature of the problems related to water management and associated decision-making processes. The social processes by which technologies are brought into use are also analyzed in this domain. This book covers in detail some existent theories and innovative concepts revolving around hydroinformatics. Different approaches, evaluations, methodologies and advanced studies have been included herein. The extensive content of this book provides the readers with a thorough understanding of the subject.
