Flood profiles of the Pithlachascotee River, west-central Florida
Data defining the magnitude and frequency of flooding are provided for a nontidal 16-mile reach of the Pithlachascotee River in Florida. These data include areal flood-frequency relations and flood heights for the 2-, 2.33-, 5-, 10-, 25-, 50- , 100-, 200-, and 500-year recurrence intervals. Flood profiles are provided for the 2.33-, 5-, 10-, 100-, and 500-year recurrence intervals. Study results indicate that flood discharges in the study area are highly variable and are one-third to one-half of regional estimates. Differences between study area and regional estimates are due to large quantities of flood-water drainage to the regional aquifer system in the upper basin, a large karst area of about 138 square miles. Graded roads and bridges located at three sites along the upper study reach will be inundated by various frequency floods. Flood inundation maps can be prepared from flood data presented in this report.
