A land use/land cover identification methodology using LANDSAT imagery has been applied to six watersheds across the U.S. The land use information is stored in a grid cell data bank and is the basis for calibration of hydrologic parameters for watershed models. Flood frequency studies have been completed on four of the watersheds with land use derived from both satellite data and conventional low altitude aerial photography. This paper discusses our experience using the LANDSAT land use classification procedure and compares hydrologic results obtained from the alternative determinations of land use. (Author).

"Hydrologic modelling of floods enables more accurate assessment of climate change impacts on flood magnitudes and frequencies. This book synthesises various modelling methodologies available to aid planning and operational decision making, with emphasis on methodologies applicable in data scarce regions, such as developing countries. Topics covered include: physical processes which transform precipitation into flood runoff, flood routing, assessment of likely changes in flood frequencies and magnitudes under climate change scenarios, and use of remote sensing, GIS and DEM technologies in modelling of floods to aid decision making. Problems included in each chapter, and supported by links to available online data sets and modelling tools accessible at www.cambridge.org/mujumdar, engage the reader with practical applications of the models"--
