Abstract

Climate change and global warming have played an essential role in human history, causing many large cultures to collapse and local people to vanish. In this study, three dust detection indices retrieved from the Moderate Resolution Imaging Spectroradiometer (MODIS) products for detecting Sand-Dust Storms (SDSs) in Iraq were adapted. The Brightness Temperature Difference (BTD), Normalized Difference Dust Index (NDDI), and Middle East Dust Index (MEDI) are three metrics. A practical example of an SDS event occurring on 5 August 2008 was studied with the proposed indices to demonstrate the capability of these indices to detect the SDSs in Iraq and validate their output based on the estimated threshold analysis. Generally, all the indices offer simple means for detecting or extracting the studied SDS events according to the contaminated area, with an average detection error varying between the three indices. The polygons of the detected contaminated area were calculated for each index and compared with the whole study area, the detection error between contaminated and not contaminated pixels for the three indices images are 12.6% for NDDI, 10.7% for BTD, and 8.5% for MEDI so from these error results we can say that MEDI index is more suitable for detecting SDSs events over Iraq.

Abstract

Due to the extensive use of geographic information system (GIS) concepts, planning and design for water resources are evolving. The effects of human activity are all around us in some places, and water resources are getting harder to find. In this situation, evaluating these resources, estimating consequences, and developing plans to lessen impacts and enhance sustainability while utilizing the finest technology available are all important. While geographic information systems (GIS) offer the best tools for managing water resources and other related issues like drought and flood risk, remote sensing offers the essential data for managing these resources. Also, GIS can be integrated with many techniques like artificial intelligence models and hydrological models. This paper aims to present a comprehensive survey of the best practices and uses of GIS technologies in water resources engineering includes, water resources mapping, rainfall-runoff measurements, flood forecasting, irrigation management, water quality and drought monitoring.
