  What is Remote Sensing? So, what exactly is remote sensing ?  For the purposes of this tutorial, we will use the following definition: "Remote sensing is the science (and to some extent, art) of acquiring information about the Earth's surface without actually being in contact with it. This is done by sensing and recording reflected or emitted energy and processing, analyzing, and applying that information." In much of remote sensing, the process involves an interaction between incident radiation and the targets of interest. This is exemplified by the use of imaging systems where the following seven elements are involved. Note, however that remote sensing also involves the sensing of emitted energy and the use of non-imaging sensors.  

In this research, has tried to find out the most crucial issues and challenges in Afghanistan regarding Water Resources Management. The following issues are the most critical issues and challenges that currently influenced the country. Climate change impacts on water resources . Due to climate change, precipitation and temperatures have changed. Climate change components variation is the case of natural disasters such as floods, drought in Afghanistan.  Water Quality Due to natural hydro chemical processes, the groundwater has affected.   People awareness regarding using groundwater As the population is increasing day per day, it has a direct effect on water resources.  Lack of management 3-decade war is the reason for the lack of water resource management, development, protection, conservation, and sustainability of water in Afghanistan. This research will be useful for understanding the factors which had affected water resources in Afghanistan, and this study will be more
