The book provides comprehensive information on possible applications of remote sensing data for hydrological monitoring and modeling as well as for water management decisions. It is intended to provide methods to support the readers in solving their own problems in hydrology and water management. Mathematical theory is provided only as far as it is necessary for understanding the underlying principles. The book is especially timely because of new programs and sensors that are or will be realized. ESA, NASA, NASDA as well as the Indian Space Agency and the Brazilian Space Agency have recently launched satellites or developed plans for new sensor systems that will be especially pertinent to hydrology and water management as are the new large-scale groundbased weather radar systems. New techniques will be presented whose structures will differ from conventional hydrological models due to the nature of remotely sensed data.
