| Abstract | ||
| This study investigates the applicability of the two-parameter climate elasticity of streamflow index to assess the impact of global warming on regional hydrology of Teeb river watershed, south of Iraq. The results indicate that the streamflow response to rainfall and temperature anomalies exhibits a non-linear relationship. A 50% rainfall increase in the Teeb watershed results in a 10% increase in streamflow at mean temperature, but no increase in streamflow for temperature increases of 1.5 C. A 20% rainfall decrease results in a (20-30%) decrease in streamflow at mean temperature but only 10% decrease in streamflow if the temperature increases 1.5 C.Results also indicate that the streamflow elasticity for climate changes is a useful index to assess the sensitivity of streamflow to both precipitation and temperature departure. Water resource issues in the Teeb watershed are likely to be more critical if the adopted climate changes scenarios are correct. | ||
