Determining the Runoff and Detention Coefficients Using Hydrological Reduction Values

Mahdi Nurbakhsh

Volume 8, Issue 31 , November 2009, , Pages 50-52

Abstract
  In a simple definition, the runoff coefficient is the percentage of the water falling through precipitation that flows over the surface. This coefficient depends in each basin on the level of interception, infiltration and evapotranspiration. Runoff is a result of the difference between the rate of precipitation ...  Read More

Prediction of Natural Occurrences With High Range of Variability

Mahdi Nourbakhsh

Volume 8, Issue 29 , May 1999, , Pages 53-57

Abstract
  Time is one of the major factors in natural events whose accurate prediction has always been considered by human. Sudden and unexpected occurrence of some of such events, especially those with great range of changes, have brought humans many problems. Today, it is tried to predict the return period of ...  Read More

Estimating Potential Evaporation Using Multi-Variable Regression

Mahdi Nourbakhsh

Volume 6, Issue 24 , February 1997, , Pages 53-56

Abstract
  Evaporation is change of liquid water into vapor. In hydrological cycle, evaporation is a complex phenomenon whose estimation requires great deal of calculations. In this study, it has been tried to present a simple method for calculating potential evaporation, and to calculate evaporation from water ...  Read More
