Statistical Modelling of Drought Indicators and Evaporation/Transpiration and Their Impact on Determining the Erosion Ability of Winds in Iraq

Abstract

Geographical studies are concerned with analyzing and interpreting its most important phenomena, especially those related to climate, which in one way or another affect the provision of harsh environmental conditions such as drought, desertification, and others, as well as being one of its prominent manifestations. As these studies are interested in one way or another in determining the mechanism of action in life, as they are interested in determining the various human activities, and in this research, the researchers were interested in adopting (10) Iraqi climatic stations to find and calculate the values of the phenomena referred to from drought, evaporation/transpiration, wind erosion and the strength of wind pressure in Iraq, using an applied quantitative-statistical method to determine the monthly and annual ranges of wind erosion for the period (1986-2018), and by applying the correlation, regression and determination coefficients. As well as cartographic representation using Excel techniques and geographic information systems (GIS).
