<br />xl <br /> <br />---- <br /> <br />SUMMARY <br /> <br />The primary objective of developing a flood proofing manual was to provide local flood plain <br />administrators and professionals in governments and private business with procedures and <br />design techniques to mitigate losses from flood. The manual illustrates examples of Colorado <br />floodproofing measures, means for evaluating flood risks, procedures for designing a low risk <br />flood structure, classifications of building materials, and the economics of implementing <br />flood proofing measures, A chapter summary of the manual is as follows, <br /> <br />Chapter I - Introduction: <br /> <br />This chapter introduces the concept of floodproofing. It differentiates between flood control <br />measures and defines the various classifications for flood proofing measures and flood proofed <br />structures. Floodproofing measures are classified as permanent, contingent, or emergency. <br />These classifications are based on the degree of action required to implement the measure <br />and when the flood proofing measure is implemented in relation to the time of flooding, <br /> <br />Chapter /I - Glossary: <br /> <br />This chapter explains all the flood. related terminology used in the manual and flood plain <br />management. <br /> <br />Chapter III - Physiographic Considerations: <br /> <br />This chapter discusses the physiographic characteristics that should be evaluated when <br />development in the flood plain is considered. The various characteristics include channel <br />cross section and slope, vegetation, soil characteristics, erosion, and sedimentation and deb. <br />ris. The discussion relates to how these characteristics affect flooding characteristics, such as <br />velocity and depth. <br /> <br />Chapter IV - Examples of Floodproofing: <br /> <br />This chapter presents pictoral examples of floodproofing practices which have been <br />implemented by Colorado communities. <br /> <br />Chapter V - Natural and Inherent Methods: <br /> <br />This chapter addresses natural and inherent flood proofing measures that exist in flood <br />plains. Floodproofing features include use of island development, natural building materials, <br />existing streets, and embankments. These types of features create areas that are more feas. <br />ible for floodproofing development by reducing velocities and depths or completely <br />eliminating flooding, <br /> <br />Chapter VI - Water Loadings: <br />This chapter analyzes the various types of loadings (forces) that are present during flood. <br />The specific water loadings and forces considered are hydrostatic, hydrodynamic, impact, ero. <br />sion forces, and embankment stability. For each force a discussion of general consideration, <br />application, and methodology is presented. The methodology gives the appropriate equations <br />required to estimate the magnitude of the forces involved. <br /> <br />Chapter VI/ - Design Criteria: <br /> <br />This chapter presents criteria and general guidelines fm general flood proofing measures, <br />elevated structures, levees, and floodwalls. This chapter addresses dimensions of the fill for <br />elevated structures on fill and general guidelines for structures elevated on posts, piers, m <br />piles. GE,neral guidelines are provided for anchming and waterproofing structures that will be <br />submerged to some degree during flooding. A general discussion of types of levees and <br />floodwalls is also given. <br />
