To say that the rapid emergence of GIS has revolutionized water engineering is no exaggeration. GIS has proven to be especially useful when looking at what if scenarios and for developing complex simulation models. This volume answers the need for an authoritative resource that provides quick access to advances in GIS as they relate to various water engineering schemes. Presenting the pioneering work of leading experts in GIS and hydroinformatics, this book is for those developing GIS and Land Based Systems applications as well as for water scientists and engineers, especially those working as water network modelers.
