<br />input data, whether these data be supplied'by the user or provided as <br />default "most probable" values by the model. To produce the most reliable <br />results, the user should endeavor to obtain the best estimates of the <br />various input parameters that time and resources allow. Secondly, because <br />the model assumes normal, steady flow at the peak, the backwater effects <br />created by downstream channel constrictions such as bridge embankments or <br />dams cannot be accounted for and the model will predict peak depths upstream <br />of the constriction that may be substantially lower than those actually <br />encountered, while peak depths downstream of the constriction may be over <br />predicted. Finally, because the "slowing down" of the floodwave caused by <br />temporary off-channel dead storage is not accounted for by the model, the <br />predicted time to peak at a certain point may be somewhat shorter than the <br />actual time to peak. Recognizing these limitations and exercising good <br />engineering judgement, the SMPDBK model user may obtain useful dam break <br />flood inundation information with relatively small expense of time and <br />computing resources. <br /> <br />. <br /> <br />V.
