A particular challenge in terms of calculations is a hydraulic shock, accompanied by discontinuities of the flow. This phenomenon has not been fully studied, so the works of many scientists are devoted to experimental and theoretical studies of non-stationary processes with column separation of liquid. In this work it was defined the nonlinear heterogeneous model based on Geospatial Information System (GIS). By the way the process of modeling for unsteady fluid flow at drinking water transmission pipeline was presented.

Quick turn-based georeferenced information is a new technology that has a positive impact on the performance and efficiency of facility systems including Heating, Ventilating, Air-Conditioning & Refrigeration (HVAC&R's). The technology of signal detection through remote reading system, provide the management of facility HVAC&R through the geo-reference world area network (Webbased GIS) based on geographic information system (GIS). This method as a new concept in the control science and optimize energy consumption can be an effective factor in design, maintenance, energy consumption management, and commissioning of the facilities and building industry. Also, this method provides online control of energy consumption of the facilities and building industry. So in this work, the model of control of HVAC&R in the context with GIS and Web-based GIS were investigated. The empirical results besides the regression mathematical analysis show that this model is able to predict and evaluate energy consumption.

KARKAS Mountain is the highest peak in Natanz, Kashan.On the one hand due to the diversity of geomorphologic units for example diversity of heights, tilt of hillsides, valleys, types of faults, and age of rock units, types of units, glaciers, and sediment, on the other hand, due to geomorphic processes such as tectonics, dry and hot to cold period of climate, luxuriant vegetation and some areas without vegetation, landslides, and rock debris it can be described as a place for research in geology sciences. This paper studies geomorphology of KARKAS Mountain and tries to interpret variety of forms and processes by using GIS. Due to the introduction of the gradient of the mountain, evidence and the fact that the slopes are currently active by internal earth activities (the dynamic forces), we conclude that, especially on the northern slopes of the mountains above 1700 meters high, it is very sensitive and its morphologic changes are happening very rapidly.
