EVALUATION OF FLOOD RISK FACTORS IN THE DESIGN OF HIGHWAY STREAM CROSSINGS. VOLUME I. EXPERIMENTAL DETERMINATION OF CHANNEL RESISTANCE FOR LARGE SCALE ROUGHNESS
The overall objective of the study is to develop an engineering systems analysis method to enhance the decision-making process in the design of highway stream crossings. This method applies economic risk techniques as well as standard hydraulic and hydrologic factors in the design of bridge waterways. Volume I presents the results of experiments to determine channel resistance coefficients from artificial roughness elements representative of heavily vegetated flood plains. These coefficients are used to define the roughness field for use in bridge backwater experiments and calculations reported in Volumes 2 and 3.
