The Effects of Physical Factors on the Storm Hydrograph The Storm Hydrograph refers to graphs that show how a drainage basin responds to a period of rainfall. Storm hydrographs are very important in predicting the flood risk and in making the necessary precautions to avoid damage to property and loss of life. Physical factors are the biotic factors which affect organisms and their surroundings‚ their surroundings in this case being the drainage basin and therefore the storm hydrograph is affected
