<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.
