CONCLUSIONS

I

1. The relations of width, depth, and velocity to discharge
at a station can be expressed as simple functions.

I

2. The rates of increase in a downstream direction in width,
depth, and velocity for streams in Kansas are similar
to those found for other streams in the Midwest, although
the rate is slightly higher and the rate for velocity is
slightly lower in Kansas.

I

3. Along a single stream and for a constant frequency of
discharge, the relations of width, depth, and velocity
to discharge can be expressed as simple functio~.
However, there is considerable scatter of points about
the relation 1 ines.

I

I

4. Statewide general ization permits the prediction of width,
depth, and velocity for specified frequencies of discharge
and for the average discharge at ungaged locations.
Individual predictions are subject to considerable
uncertainty.

5. Information on bed grain size did not improve the state-
wide general izations.

6. Reaeration coefficients can be estimated from the
equation k2 = 3.3v/dl .33, using estimates of v and d
from the hydraul ie-geometry equations.

7. The equations wil I provide useful information in planning
for certain water activities.
