dc.description.abstract The suitability of the Rational Equation for the derivation of steam/lows for small ungauged watersheds is studied. A Unit Hydrograph can be derived using the peak discharge obtained from the Rational Equation and using unit depth of rainfall in calculating the Rainfall Intensity. Possible alternatives for selection of sub catchments. selection of a guideline to determine the Runoff Coefficients and the Time of Concentration were taken into account. A significant variation of the results was observed with the selected alternatives In order to select a better alternative comparison of generated streamflows with the observed values is required. en_US
