WebV = K * i. (where V is the velocity of the groundwater flow, K is the hydraulic conductivity, and i is the hydraulic gradient). We can apply this equation to the scenario in Figure 14.5. If we assume that the permeability is 0.00001 m/s we get: V = 0.00001 * 0.08 = 0.0000008 m/s. That is equivalent to 0.000048 m/min, 0.0029 m/hour or 0.069 m/day. WebAdditional input puts the river into storm flow. This input comes from infiltration, throughflow and run-off. If the discharge breaches the channel capacity a stage called bankfull is reached. Falling Limb - Following peak discharge the cumecs of water in the river decreases. Name the key features of a storm hydrograph.
