One-minute rain rate data over a 10-year period-of-record at each of 41 locations in the contiguous U.S., and for a 6 1/2-year period-of-record at 1 location in Puerto Rico, were extracted from original weighing raingage recordings. The data were analyzed to determine monthly, seasonal, and annual rain-rate frequencies, durations, and probabilities at locations representing a large variety of climatic rainfall regimes. These analyses are particularly useful for estimating EHF (Extremely High Frequency) communication outages due to the increasing effects of attenuation caused by rain at frequencies above 10 GHz. An attenuation model was used to estimate the effects of rain attenuation at all 42 locations. Analyses of the 1-min rain rates, and outage estimates for various frequencies and propagation-path elevation angles are presented.

The technological advances of recent years include the emergence of new remote sensing and geographic information systems that are invaluable for the study of wetlands, agricultural land, and land use change. Students, hydrologists, and environmental engineers are searching for a comprehensive hydrogeologic overview that supplements information on hydrologic processes with data on these new information technology tools. Environmental Hydrology, Second Edition builds upon the foundation of the bestselling first edition by providing a qualitative understanding of hydrologic processes while introducing new methods for quantifying hydrologic parameters and processes. Written by authors with extensive multidisciplinary experience, the text first discusses the components of the hydrologic cycle, then follows with chapters on precipitation, stream processes, human impacts, new information system applications, and numerous other methods and strategies. By updating this thorough text with the newest analytical tools and measurement methodologies in the field, the authors provide an ideal reference for students and professionals in environmental science, hydrology, soil science, geology, ecological engineering, and countless other environmental fields.
