RISK EVALUATION OF LOW WATER-CROSSING STRUCTURES

This study investigated the conditions under which one would consider the selection of a low water crossing (LWCS) rather than a higher bridge. A public opinion survey was conducted to ascertain the opinions of decision makers from county, state, and federal agencies. The paper describes the analysis of the questionnaire with reference to the decision model, the importance of intangible factors, absolute constraints for not using LWCS, and other comments, as well as preferences for the selection of LWCS. The most important intangible factors for the selection fo LWCS were as follows: possbile damage to human life, amount of daily traffic, frequency of possible flooding, legal considerations, and the location as part of an emergency route. These and other factors are discussed.
