FLO-2D hydraulic information provided is from two-dimensional hydrologic and hydraulic computer models from floodplain delineation studies. Each group of information values provided applies to a square referred to as a grid element. The size of these grid elements vary from flood delineation study to flood delineation study, but are the same within the flood delineation study.
The estimated average peak discharge in cubic feet per second (cfs) crossing the grid element in the direction described below. The FLO-2D model computes discharges entering or leaving the grid element in eight directions. The user should be aware that flow might be leaving the grid element in other directions than that reported here. What is provided is the largest total peak discharge leaving the grid and the direction of that discharge.
The estimated dominant direction of the peak discharge.
The estimated average peak water surface elevation (WSEL) in feet for the grid element. The vertical datum is the North American Vertical Datum of 1988 (NAVD88). The water surface elevations provided are most representative of the center of each grid element. An engineer can estimate an elevation at a point in-between the centers of grid elements by appropriately interpolating between the elevations of grid elements surrounding the location in question. In the event that peak discharges and/or water surface elevations at a particular location seem incorrect in relation to the surrounding grid elements, the user should consult with the Flood Control District on applying the FLO-2D information in that area.
