Quick turn-based geo-reference 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.

Drainage of surface runoff is one of the main problems in the Rasht city. In this study, using HEC-GeoRas in GIS environment and maps of the river, geometry of Goharrood river bed and border is obtained. Then, by using this information in the hydraulic model of HEC-RAS, hydraulic behavior of the river is simulated and then after transferring again into the GIS, river flood area is drawn. According to the land-use map of the area, flood prone areas are categorized into three zones with low, medium and high risk and finally flood prone areas according to their land-use (residential, agricultural, industrial, etc.) are identified and presented. The area under this study is a 15 km portion of the Goharrood river inside the city of Rasht. The flood maps produced by the discharge with a return period of 50 years indicated that river flooding happens only in a 500 meters region, north of the city, called Siahestalkh.

In the present study, land use changes in Babavali Basin watershed have been evaluated over a 13- years period. For this research, 2000 Landsat 7 satellite ETM + images and Landsat 8 satellite imagery have been used. After performing the required actions in the preprocessing stage, the maximum probability of the images is classified. The land use map of the region was obtained in 2000 and 2013 the validation results with ground realities and field visits indicate the total accuracy is equal to 0.89 and 0.88. The Kappa coefficient is equal 0.88 and 0.88 in the ETM + images of 2000. Therefore the Landsat 8 of 2013 was acceptable.

Quality and quantity of phytoplankton depend on the load nutritious in part on water. Therefore, the use of phytoplankton in different ecosystems, water is used to measure quality or pollution of water. The Bijar river is at Guilan province as the main rivers in Iran. In addition, as the main source of drinking water The Bijar river uses in agriculture and economy area. In this study, the impact physicochemical factors on the composition and frequency of phytoplankton in different seasons were analyzed .The results of the study of biological River Bijar, indicates the presence of 5 branches and 57 Genus the region. The frequencies of Bascillariophyta branches on other branches were dominant in all seasons. Data collected for all the parameters are normally distributed and determined by using the Kolmogorov-Smirnov test. The correlation between phytoplankton and physicochemical parameters shows the number of phytoplankton significant correlation with the parameters of temperature and PH and nitrogen. In this work, it also uses GIS software and take advantage of various colors, color zoning qualitative phytoplankton were prepared.
