2020	Sedimentological Analysis and Remote Sensing Technique of Quarries Monitoring and their Environmental Impact	Journal of Green Engineering (JGE)
Natural aggregate such as crushed stone, sand, and gravels is a pivotal side of the economic infrastructure. The present work mainly aims to study 1) the quality of gravels of Chailat quarries through fieldwork and laboratory analysis, and 2) the area, size, and direction of expansion of quarries and estimating the effect of quarries on the environment using remote sensing techniques by analyzing time-sequential changes and performing of GIS. The results of laboratory analysis showed that the composition of the gravel is made up of a high percentage of carbonates (70.82%). This type of gravel has a high building material property and perfectly matched with the composition of the Iraqi Quality Standard (IQS) for concrete gravels. The visual interpretation results of Landsat images reveal that the quarries area in 2019 has developed relative to 2001 by about 425% from 2.42km2 to 10.29 km2. Although the quarries are located in an ideal location where it is more than 25 km from the nearest residential area and about 10 km from agricultural areas, one of the main environmental hazards that may be caused by quarry operations is silt runoff and saline waters which result from the washing of materials to remove the salt and clay materials from these sediments. One of the important things that have been recommended by the current paper is the need to treat washing water, as this water will be of high concentrations of salts and result in contamination and increases the salinity of the soil and underground water.
