Book Description
During ten years serving with the USDA Soil Conservation Service (SCS), now known as the Natural Resources Conservation Service (NRCS), I became amazed at how millions of dollars in contract monies were spent based on simplistic hydrologic models. As project engineer in western Kansas, I was responsible for building flood control dams (authorized under Public Law 566) in the Wet Walnut River watershed. This watershed is within the Arkansas-Red River basin, as is the Illinois River basin referred to extensively in this book. After building nearly 18 of these structures, I became Assistant State Engineer in Michigan and, for a short time, State Engineer for NRCS. Again, we based our entire design and construction program on simplified relationships variously referred to as the SCS method. I recall announcing that I was going to pursue a doctoral degree and develop a new hydrologic model. One of my agency's chief engineers remarked, "Oh no, not another model!" Since then, I hope that I have not built just another model but have significantly advanced the state of hydrologic modeling for both researchers and practitioners. Using distributed hydrologic techniques described in this book, I also hope one day to forecast the response of the dams I built.

Book Description
Most computer models used in the flood risk analysis of rivers have inadequate functions in its spatial analytical capabilities and without sediment transport simulation capacity or suitable equations to represents correctly in-situ hydraulic processes. As a result, this book presents the well defined methods on sediment transport modeling using GIS. Step by step guide given for developing a new total bed material load equation and embedding the equation in the SEDFlood model. The tight coupling procedures which gives a user friendly, menu-driven GUI for ArcView GIS and SEDFlood integration and enables two and three-dimensional (2D & 3D) digital floodplain delineation was developed and demonstrated based on worked examples. The importance of hydraulic field measurements and the techniques for hydraulic results validation were shown. It is evident that GIS can be uitlised successfully for floodplain analysis and its integration with hydraulic model is not only feasible but also mutually beneficial for both GIS users and hydraulic modelers. This book is best utilised by hydrological and hydraulic modelers and GIS specialist who worked on floodrisk analysis

Book Description
Floodplain maps serve as the basis for determining whether homes or buildings require flood insurance under the National Flood Insurance Program run by the Federal Emergency Management Agency (FEMA). Approximately $650 billion in insured assets are now covered under the program. FEMA is modernizing floodplain maps to better serve the program. However, concerns have been raised as to the adequacy of the base map information available to support floodplain map modernization. Elevation Data for Floodplain Mapping shows that there is sufficient two-dimensional base map imagery to meet FEMA's flood map modernization goals, but that the three-dimensional base elevation data that are needed to determine whether a building should have flood insurance are not adequate. This book makes recommendations for a new national digital elevation data collection program to redress the inadequacy. Policy makers; property insurance professionals; federal, local, and state governments; and others concerned with natural disaster prevention and preparedness will find this book of interest.

Book Description
The threat of flooding is a serious concern to local governments. During a flood event, it is critical to have accurate estimates of where the flood is. Hydrologic models can serve as valuable tools in urban planning, especially in environmental planning. The Geographic Information System (GIS) technology has been used for storing, analyzing, and visualizing spatial information. By linking GIS, computerized hydrologic model, and expert knowledge into a spatial decision support tool, this project is to assess flood hazard for different land-use scenarios for a range of rainfall events in the Mill Creek Watershed. This study investigated the effect of urbanization and agricultural development on runoff. By comparing land use in 1980 and 1992, runoff was calculated and flood areas were delineated using the runoff curve number method. The comparison study showed that both urbanization and agricultural development result in an increase in surface storm water runoff and greater flood area.

Book Description
A two-dimensional horizontal finite element numerical model (RMA-2) was applied to a 15 mile (24 km) river channel-floodplain reach in West Germany. Previous applications of such models have been restricted to much smaller scales. The results indicate that finite element schemes may successfully estimate river stage in large scale floodplain applications. Computed stage hydrographs compared well with observed data using loss coefficients within expected ranges. Two-dimensional flow models have been applied to certain classes of river channel problems. Applications have included detailed analyses of flow patterns near structures such as bridges and floodplains. In all these problems the scale of interest has been small, e.g. reaches of river a few river widths long. Many estuary studies have been done that were of large scale; some of these utilized a hybrid (numerical plus physical) modeling technique. In a review of the application of finite element methods to river channels, Samuels reported that the river channel was resolved separately from the floodplain in only two studies. Missing in previous work is attention to large scale floodplain modeling. The work reported in this paper focuses on the feasibility and accuracy of applying a two-dimensional flow model to a large floodplain. Traditional floodplain studies have used semi-empirical flow routing with steady, one-dimensional computation of water surface elevations to define inundated areas. Keywords: Army Corps of Engines.
