Q4
There are many catchment properties which influence runoff and each may be
present to a large or small degree. Identify FIVE (5) major catchment
characteristics and their effects on runoff.
(a)
Rating curve is a graph drawn connecting the water level elevation of a river
channel at a certain cross-section with the corresponding discharge at the section
which represents the results of a river discharge measurement. One of the
measurements may be made is by velocity-area methods. Demonstrate this
measurement method to obtain an estimated reading for the streamflow.
(b)
3
Sketch and compute streamflow for the measurement data given in TABLE
Q4(c) using mean-section method. Given that the river width is 12.5 m
