Abstract
Given the resource limitations and the upward trend of development, if this movement is not accompanied by proper management and planning, it can create problems. Because any development requires the exploitation and use of natural resources. Therefore, it can have direct or indirect effects on nature. Optimal use of soil and water resources and ways to predict and reduce their problems have always been the objectives of correct and principled agricultural development in order to obtain the highest returns from the minimum resources. Water use optimum management has been the subject of much discussion in many expert circles in the past few decades, in all of which, emphasis has been placed on monitoring and evaluation as the keys to success. Many irrigation and drainage networks operate on the basis of supply and demand management and usually deliver water regardless of the actual water requirement. In irrigation and drainage networks, due to the scattering of farms, the size of the land, the variety of cultivation and the distance between the place of extraction and the point of delivery, management of utility and maintenance is not possible without taking the interactions of the above factors into account. Moreover, in irrigation networks, descriptive data is produced daily on a massive scale that requires organizing, analyzing and deciding, which are very difficult with traditional methods and requires the use of the new systems such as GIS and remote sensing. The purpose of this paper is to investigate the geographic information system and remote sensing and their application in irrigation and drainage networks management.
