The book presents a comprehensive study of the percolation of water from surface runoff with a focus on the retention capacity and intensity of precipitation.Discussing the state of the art in scientific knowledge and solutions for the infiltration of water from surface runoff, the book addresses a wide variety of rainwater management issues, from precipitation, surface runoff and water infiltration, to impact on the drainage system. Although modern urban hydrology has improved the management of rainwater runoff for flood protection, public health, and environmental protection, current methods of drainage in urban areas mean that there is a continued threat to the regime of water flow and water resources. In this context, the book presents a new approach to rainwater management based on a unique fusion of hydrology, hydrogeology, urban engineering, and water management. It also includes research findings that are helpful in developing recommendations and technical guidelines for the use of infiltration systems in urban areas.
