New Tools for Economic Evaluation of Channel Deepening Projectsby David F. Bastian, Inst for Water Resources, Ft., Belvoir, VA, USA,
Abstract: The Institute for Water Resources has developed a data base to facilitate economic evaluation of channel deepening projects. After extensive research, data elements were selected from various federal agencies, industry and publications. These were integrated to provide a data base which allows analysis down to a ship movement level, complete with ship and voyage characteristics including vessel draft and commodities laden and unladen with their corresponding weights and values. The data base was tailored to personal computer (PC) usage through dBase III software. This allows for ease in data sorting and merging while allowing for conversion to Lotus 1-2-3 spread sheet displays and statistical analysis. By adapting the data to the PC the project manager has greater flexibility and control. The data base has been successfully used in economic evaluation to show existing traffic and statistics on tide riding and underkeel clearance.
