The reason the "Flood EL" and the "Time to Flood EL" fields are blank in your DAMBRK output is because the Flooding Elevation data field (defined in the Channel Cross Section Description screen) has been left blank. This field typically represents the channel bank elevation (or, when flooding is considered to occur). If you enter a value for each cross section, then DAMBRK will compute the Time to Flood Elevation value. DAMBRK will also generate a nice graphic plot showing this result.
