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).

The main objective of this work was to investigate the potential of utilizing geographic information systems (GISs) in identifying hazardous pedestrian accident-prone locations. The study was performed for roads in Irbid city-Jordan for the years 2002 and 2003. Pedestrian accident data was analyzed by pedestrian characteristics, driver characteristics, accident time and location, environmental conditions, vehicle speed and characteristics, and accident severity. Pedestrian accidents were correlated to operational factors, including traffic volume, vehicle speed, pedestrian volume, street length, and access points. Hazardous locations of vehicle-pedestrian accidents were identified using a GIS query builder. Results showed that there was a high potential for GISs in studying pedestrian accidents.
