Hydroinformatics is a subfield of informatics that focuses on the use of information and communication technologies (ICTs) to address the major issues related to the effective and equitable use of water for a variety of purposes. Hydrodynamics is a branch of physics, which is engaged in the study of the motion of fluids as well as the forces acting on the solid bodies submerged in fluids. Hydraulics refers to a type of technology that involves the utilization of liquids and their mechanical properties. It is an applied science based on chemistry, engineering, and other sciences. Concepts from the fields of environmental engineering, hydraulics, and hydrology along with other disciplines are integrated into hydroinformatics. This book unravels the recent studies in the fields of hydraulics, hydrodynamics, and hydroinformatics. It will serve as a valuable source of reference for graduate and post graduate students. It strives to provide a fair idea about this discipline and to help develop a better understanding of the latest advances within this field.
