Study on natural processes related to water as well as knowledge about runoff and hydrological conditions is necessary for improvement of water management in Iran. Since most of watersheds in Iran are ungauged, so using hydrologic models to simulate the runoff is inevitable. In this study, continuous distributed hydrologic model WetSpa was used to simulate Zoshk watershed runoff. Three basic ma...

over the past decades a number of approaches have been applied for forecasting mortality. in 1992, a new method for long-run forecast of the level and age pattern of mortality was published by lee and carter. this method was welcomed by many authors so it was extended through a wider class of generalized, parametric and nonlinear model. this model represents one of the most influential recent d...
