In the distribution network analysis, a step-by-step algorithm based on flow and pressure equations is used. In this method, solving energy and continuity equations in each repetition is used to analyze the branch and loop networks in separate network segments. In this way, numerically, the network was maintained by one-way pressure regulating valves with an independent function. The present work examines the baseline reclamation and development model in the District Metering Area's "DMA" and in Independent Districts and the separate sections of the network that are separated from the permanent boundaries of the network while analyzing the flow and pressure parameters. The results of this work show that the intelligence of the facility will ensure the realization of the objectives of the model of reclamation and development.

The purpose of this research is to extract changes of shore line in Bushehr Province using satellite imagery processing. In this study, land use maps produced by +ETM and OLI Landsat sensor images by Maximum Likelihood method in 2006 and 2016, has been classified in 5 classes: Vegetation, water, man-made, pastureland and bay. According to given Kappa coefficient and overall accuracy, the results of this monitoring showed process of coastal changes during the 10-year period has been most affected by the construction of offshore structures and the largest amount of coastal morphology has been the forefront of this complication at the edges of the breakwaters to the sea.

Landslides are one of the geomorphological hazards responsible for considerable damages as direct and indirect expenses in different regions every year. They play a major role in the destruction of human installations, human casualties, destruction of pastures and forests, and sedimentation in watersheds. This study aims at evaluating a Promethean model and entropy in landslide zonation of Lahijan city and identifying the impact of all the six factors in landslide and landslide hazard map using the Promethean model and entropy. It then provides scientific solutions for better management of the region against landslide hazard. The region landslides were initially identified using the visual interpretation of different maps and data. Through examining the landslides in the region, the sixfactors of lithology, distance to fault (DFT), topography, slope, slope direction, and land use were identified as the effective factors in a landslide occurrence. With respect to the characteristics obtained from the landslides in the region, the layers were weighted and classified based on experts opinions and the Promethean matrix and entropy weight were formed for them.
