WATERBURY, Conn. -- Today, Haestad Press announced the publication of its comprehensive, practical guide to floodplain management, Floodplain Modeling Using HEC-RAS. Authored by U.S. Army Corps of Engineers veteran Gary Dyhouse, this new textbook is an invaluable tool for students of floodplain management and practicing modelers and managers. "With Floodplain Modeling Using HEC-RAS and the program documentation, readers should be able to address nearly any modeling problem encountered during a water surface profile analysis," said Dyhouse. "I am very proud of this book and believe that it will be an extremely valuable addition to the hydraulic library of practicing engineers and engineering students throughout the world." This 700-page textbook provides expert instruction and sound advice on completing a floodplain study, including planning the study; determining the floodway; modeling bridges, culverts, and other special features; and modeling unsteady flow. In addition, it contains one-of-a-kind, hands-on instruction for using HEC-RAS, the worldwide standard simulation tool from the U.S. Army Corps of Engineers. Together the textbook and accompanying software emphasize detailed knowledge of flood-flow behavior through a floodplain model, demonstrate the impact proposed hydraulic works will have on floodplain behavior, and assess scenarios for flood protection programs. Dr. David T. Williams, president of WEST Consultants, Inc., said, "Water resources professionals, novices to experts, will find this book extremely helpful in understanding the mechanics of applying HEC-RAS to river situations and, most importantly, in determining what techniques to use to simulate river behavior." Available for $195, Floodplain Modeling Using HEC-RAS includes Haestad Methods' HEC-Pack(TM) software. HEC-Pack for floodplain management includes four industry-standard products developed by the U.S. Army Corps of Engineers Hydrologic Engineering Center: graphical HEC-1 and HEC-HMS for hydrograph analysis, HEC-RAS for water surface profile analysis, and HEC-GIS for integrating floodplain modeling with GIS. With the bundled software, professionals can complete the problems at the end of each chapter to earn Continuing Education Units (CEUs). Key topics in this textbook include: * An easy-to-understand introduction to open channel hydraulics * Planning floodplain modeling studies with defensible time and cost estimates * Modeling bridges, culverts, and other special features * Calibrating and operating models for peak performance * Modeling floodways, including coverage of FEMA flood insurance guidelines * Developing routing information for use in hydrology programs * Designing and evaluating channel modifications * Analyzing bridge scour * Modeling unsteady flow
