EVALUATION OF FLOOD RISK FACTORS IN THE DESIGN OF HIGHWAY STREAM CROSSINGS. VOLUME IV. ECONOMIC RISK ANALYSIS FOR DESIGN OF BRIDGE WATERWAYS

An engineering systems analysis technique has been developed to facilitate the economic risk analysis for highway stream crossings. The technique is based on a probabilistic approach, incorporating hydrologic, hydraulic and economic factors in the engineering analysis of ridge waterways. It relates the initial construction costs, flood-related damage and damage to properties from backwater to crossing design and flood frequency. The method of risk analysis is implemented by a model in the form of a computer program using FORTRAN program language. The other volumes of this study are: (I) Experimental Determination of Channel Resistance for Large Scale Roughness; (II) Analysis of Bridge Backwater Experiments; (III) Finite Element Model for Bridge Backwater Computation; (V) Data Report for Spur Dike Experiments. /FHWA/
