• Abstract:
  A significant part of the cost of most highway projects is attributable to drainage facilities, such as bridges, highway culverts, storm drains, and water quality and quantity control structures. Design of these facilities involves a hydrologic analysis to determine the design discharge, and a hydraulic analysis of the conveyance capacity of the facility. Although most hydrologic and hydraulic calculation procedures are available in computer programs, the use of which has significantly reduced the mathematical effort involved, a substantial effort is still necessary to establish and manipulate the data required for input into those programs. In this research project, a geographic information system (GIS) for assisting in the design of highway drainage facilities has been developed. This GIS reduces the analysis time and improves the analysis accuracy by integrating digital spatial data describing the watershed with standard hydrologic and hydraulic computer packages. The focus has been on two main topics: (1) determining flood peak discharges and hydrographs, and (2) floodplain mapping.
