This book covers the various ways in which rivers discharge water and sediment load, which is characteristic of the current situation caused by both human activity and the natural riverine environment. The knowledge of river inclinations and flow patterns points to more river ecosystem management and current multifaceted conditions. Technology advancements in river watershed studies have demonstrated the difference between natural river systems and human-influenced hydrological environments and surface processes. Lastly, the relationship between river systems and modern activity is impacted by climate change which is also discussed in this volume. This edited book is organized into four parts, each discussing a different aspect of modern river science for watershed management, including GIS and hydrogeological applications, rainfall-runoff modeling that is up to date, hydrological processes, artificial intelligence, and GIS. Moreover, it provides a wealth of information about watershed management, particularly for researchers and experts in the hydrogeological field. It covers advanced applications of river morphometric dynamics conditions, flood risk assessment, sediment load discharge, and their flux measurements, as well as field-oriented aspects of the river environment and GIS. The book can be used to update current river science studies and to expand scientific understanding for projects related to studies. The edited book is primarily intended for postgraduate students, researchers, and experts and practitioners in the fields of hydrology, field hydrogeology (water resource exploration), dam studies, and groundwater potential investigation. It is also intended for young researchers, scholars, and practitioners working in the field of water resource exploration.
