Factors affecting

river discharge Factors affecting river discharge The storm hydrograph shows variations in a river's discharge over a short period of time, usually during and immediately following a rainstorm. River discharge is the volume of water passing through a point in the river and is measured in cubic metres per second (cumecs). The starting and finishing level shows the base flow of the river. As storm water enters the drainage basin the discharge rises, shown by the rising limb, to reach a peak. This indicates the highest flow in the channel. The receding limb shows the fall in discharge back to the base
level. The time delay between maximum rainfall amount
and the peak discharge is the lag time
