ABSTRACT: Bank full hydraulic geometry relationships relate stream channel to watershed size for specific physiographic regions. This paper presents bank and recurrence intervals the Southeastern Plain coercion flat woods subtype of Middle Atlantic Coastal ecoregion found within North Carolina's province. Cross‐sectional longitudinal survey data from gated unpaged streams were used compute dimension profile information. Power functions developed, relating drainage area discharge, cross‐sectional area, width, mean depth. Recurrence events estimated gagged using both a Log‐Pearson Type III distribution peak annual discharge partial‐duration series average daily discharge. Results methods indicate that study are below one year. Determinations by most part inconclusive (less than year), while partial duration 0.19 year average, ranging 0.11 0.31 years.
