Both our fresh and salt-water resources have been affected by the development of our growing population and demands. The ability to transfer water across many of these man-made barriers using culverts, in a manner that resembles that of the natural environment, is the driving force behind the development of this report. Culverts would be one of the most common types of structures that transfer water across roads, barriers and obstacles that are not part of the natural environment. This report outlines a methodology developed for the Department of Fisheries and Oceans, using some of the latest technology, software and information available, to determine culvert design characteristics necessary to transfer a peak amount of water that may impact an existing or future structure. The methodology walks through a step-by-step process, acquiring the necessary data to determine the proper culvert design, without having to leave the confines and comfort of the office. The report then outlines the use of the acquired data in determining the design of a culvert system. This developed methodology was finally used in a case study, to verify its effectiveness and to determine the specific requirements for a culvert system at the site-specific location. The result of the developed methodology was a time efficient and a cost effective method in determining necessary culvert design parameters using readily available technology, software and information. The developed methodology was executed to verify a proposed culvert design from the Department of Transportation to the Department of Fisheries and Oceans. The results of this verification, confirmed that the developed methodology was a very powerful tool.
