Why perform Hydrologic and Hydraulic Analysis?
Whether designing bridges or culverts, stabilizing stream channels or conducting flood studies, the information collected from Hydrologic and Hydraulic analysis is important to the design. This information helps the engineering staff at Jason Dismukes, LLC; determine what materials to use for the project, as well as, the engineered design best suited to achieve the project goals. These studies are critical in determining peak flow rates through hydraulic structures like, culverts, bridges, and spillways on dams. They also allow us to approximate the water surface levels associated with peak flows and the potential for flooding, up and down stream, of such structures.
How do we create hydrologic and hydraulic models?
Helpful tools for gathering data are, the FIRM (Flood Insurance Rate Mapping), maps. These are created by FEMA and show flood risk zones and their boundaries or may show floodways and BFE (Base Flood Elevations). These maps, and the studies conducted to produce them, are useful to approximate the degree of flood risk in certain areas. Often the “100-year-flood”, which is defined as a statistical event that has a 1% chance of occurring each year by FEMA, is used as a means of estimating the chance of a flood in a specific area. At Jason Dismukes, LLC we use the latest software programs and methods, developed by the US Army Corps of Engineers and other Government agencies, to create the hydrologic and hydraulic models. A compilation of data is used to build these models. They include, but are not limited to; soil types, land use, land slope, topography and watershed area.
