Analysis of Sand Dunes Accumulation using Remote Sensing and GIS
Journal Title: International Journal of Trend in Scientific Research and Development - Year 2019, Vol 4, Issue 1
Abstract
Sand dunes is one of desertification phenomenon that hinder land resources and human activities. It threaten to bury human settlement, roads, farms, water and other resources. Due to many environmental and climate conditions, there are many places around the world suffering from sand movement and mobile dune creep onto cultivated land and human settlements. Sand dunes have a fragile environment where, instability with a series of changes lead to a system not in equilibrium with its surroundings within an arid and hyper arid climates changes. These changes usually characterized by increase of evaporation and long periods of dryness, very low rainfall and vegetation. The aim of this research work is to apply remote sensing and GIS techniques to monitor and analyze sand dunes accumulation in the northern part of Sudan. Three successive satellite images acquired in different dates were used as the main source of data in this research work. A digital elevation model was also needed for topographic analysis. GIS was used to analyze output remote sensing data. Results, reflected that, sand dines accumulated during the last years and its accumulation in progress by 0.4 every year. Moreover, 50 of the study area is expected to be covered by sand dunes after less than 20 years. From topographic point of view, sand dune heights reached be 20m. These results present clear indicators of desertification that faces the study area.
