The hydroinformatics tools viz. simulation modeling, SCADA, remote sensing and GIS, artificial intelligence etc are now a days, generally used in the planning of water based systems. These are quite young technologies, but complex and so budding engineers could keep a safe distance from these courses. This book will serve as a single textbook having comprehensive information of all above topics in a single book. In this book, a wide and varied scope of hydroinformatics is concise in the simple language for easy understanding and remembrance of the readers. The aim of this book is to introduce the budding engineers with hydroinformatics and it's tools for planning and management of water based systems. Each chapter describes basic preliminary information about the topic. This book will be helpful to undergraduate and postgraduate engineering students in preparation of the subject and research, thus giving wider application of hydroinformatics.
