Butzer and Freeman write that under normal conditions the Nile inundation reaches bankfull stage
in the southern Nile by mid-August and in the northern Nile (where the Israelites lived) 4-6 weeks later, which puts its highest level around the beginning of October.
When the water level is even with the banks, the river is at bankfull stage
where, A is cross-sectional area at bankfull stage
, R is hydraulic radius, which is a ratio of A to sum of width and twice the bankfull depth, S is an average channel slope and n is Manning's roughness coefficient.
023) at bankfull stage
was consistent with a roughness value derived from measured flow velocities at bankfull stage
(n = 0.
corresponds to the discharge at which overbank flow is incipient.
Participants will learn about stream processes related to channel formation, field assessment, techniques to identify bankfull stage
, the Rosgen classification system for natural streams, channel evolution, and restoration options for impaired streams.
