Assimilative Capacity Calculations
a) Slope
From the USGS topographic maps the stream surface slope was estimated to be //.0 feet/mile.
b) Velocity
Mean velocity and depth were estimated from USGS stream gauging data for the 7/10 low flow condi-
tions as:
depth
velocity = p,,T �y
c) Reaeration Coefficient K2
The value of K? was estimated by the method devel.oped by E. C. Tsivoglou and is given by the fol-
lowing equation:
K2 (290C) = 0.96 dh/dx V
Where dh/dx = water surface slope (feet/mile)
V = mean river velocity (fps)
K2 (base e @ 290C)
d) Deoxyygenation Coefficient K1
In the absence of adequate stream BOD data, k1 was assumed to be 0.35 per day at 200C. This value
is corrected for temperature and bed activity by the following equation:
K1 (290C) = 1.51 {k1 + d (n)1
Where k1 = assumed bottle deoxygenation rate, (per day)
v = mean stream velocity (fps)
d = mean stream depth (feet)
n = coefficient of bed activity
K1 (base e @ 290C) _ % 5
e) Groundwater runoff under 7/10 low flow conditions was estimated to be �4/-,w:

Predicted stream values were obtained using
the above hydrologic conditions
