Time of Redistribution

The effect of storage is to redistribute the hydrograph by shifting the centroid of the inflow hydrograph to the position of centroid of the outflow hydrograph. The time by which it is shifted is called Time of Redistribution.

• This is the time between the centroid of the outflow and inflow.
  -Time of flood movement = Time of redistribution + Time of translation
• The process of redistribution modifies the shape of the hydrograph.
• The process of translation changes the position of the hydrograph.
