Since the set of natural and human factors contributed to the damages caused by the landslide, this phenomenon is known as the limiting factor in land development policies. One of the most important solution to reduce the damages caused by landslides, is to avoide these areas. For this it is essential to provide high accuracy maps of landslide hazard zoning by an available and suitable method. Thus in this study GIS (Geographic Information System) was utilized to determine the high risk areas and evaluate the impact of various factors. At first the influenced factors were selected by field and other reserchers studies then the layers were prepared on GIS ( by the use of ArcGIS 10.2). These layers are lithology, slope, aspect, land use, road networks, distance to fault, elevation and drainage watershed in Emamzade Ebrahim watershed in west of Guilan province, Iran. In step 1, standardization of the layers was done using Fuzzy logic. Step 2, analyze hierarchi prossess (AHP) was used to pair-wise comparison of these factors and the weight of each factor, which represents the degree of their influence had been calculated and finally landslide hazard zonation map was prepared with different sensitivities. Slope by the weight of 0/308 and lithology 0/231 had highest impact and should be more emphasis and considere on basin development planning managers and policy makers. Also 39% of the basin area has low sensitivity and 2% has very high sensitivity to the risk of the occurrence of landslide hazard. Manuscript profile -

To accomplish this study first by using of field investigation the activities which leads to risk in construction of Caspian port water front were identified and in order to extract the significant risks the specialists questioner (Delphi) was used. Finally among the identified risks, 10 environmental risks were chosen for prioritizing.After identifying the risks, indicators such as probability, severity of risk and the sensibility of the environment were selected as prioritizing criteria. AHP method and ECPRO 2000 software, for determining the risk probability, for determination the severity of risk scores and the reference texts for determining the values of sensitivity were applied. After determining the indicators, the TOPSIS software was used to risk prioritizing. The results of prioritizing studied risk showed that the highest risk is related to increased turbidity, deformation of substrate and water pollution are with weights 0.938, 0.898 and 0.662 respectively.

Therefore, knowledge of their changes plays an essential role in management of these areas. Remote sensing is one of the most advanced and effective technology for monitoring environmental changes and resource management. The purpose of this research is to detect the land use /cover changes in Bojagh National Park in Guilan province during 2000-2017. For this purpose, the images of ETM+ sensor from the landsat 7 were taken in the year 2000 and the images of OLI sensor from the landsat 8 were taken in the year 2017. After applying the necessary preprocessing on the images, the training points were selected for each user class in sufficient number and with appropriate processing then, the land use / cover map was produced using the supervised classification method with maximum likelihood algorithm. Using the Overall accuracy test and Kappa coefficients, accuracy of the produced maps was determined. The results of the study indicated that the areas of the sea, grassland and the areas of the waterbody parts has decreased and the areas of the agricultural, marshland, man-made, woody and bare lands users show an increase during the study period.

4 - Cheese whey recycling, the right approach to prevent environmental damage

Whey is a water-soluble part of milk that is obtained by adding acid, heating, and coagulating the cheese. This yellow liquid contains a lot of lactose and mineral compounds such as calcium and phosphorus, which is important to achieve in order to use as a food source and prevent environmental pollution. Since the wastewaters of the dairy industry have the highest levels of contamination, if the untreated wastewaters of this industry are discharged, serious environmental problems will be inevitable. On the other hand, a reduction in existing reserves and environmental problems followed by increasing use of fossil fuels has prompted researchers to produce new sources of renewable energy, and it can be said that new biological technologies, such as the use of whey as a way to produce biofuels, reduces the environmental problems of dischrging this kind of wastewaters into nature. Today, using biological technology, these compounds can be used to produce biofuels such as hydrogen, methane, and ethanol. So far, various methods and tests have been performed to produce these fuel sources and in this study, the effective strategies for recycling whey and preventing environmental damages are investigated.

In this research, a more accurate algorithm was determined by comparing the classification accuracy of two artificial neural network and support vector machine algorithms, and it was used to examine the process of the land use changes. The present study was performed in Boujagh National Park, in the Guilan Province, during the years 2000 to 2017, using satellite imagery ETM and OLI of Landsat 7 and 8. The results of the research revealed that the support vector machine algorithm with overall accuracy and Kappa coefficient of 86.42 and 0.83 respectively for the year 2000 and, 90.65 and 0.88 for the year 2017, classified the satellite images more precisely, in comparison with the artificial neural network algorithm with overall accuracy and Kappa coefficient of 83.71 and 0.80 respectively for the year 2000 and overall accuracy and Kappa coefficient of 89.25 and 0.87 for the year 2017. Therefore, the land use maps of the support vector machine algorithm were used to determine the land use changes. The study of land use change by this method concluded that the areas of the waterbody, sea, grassland and agriculture have decreased and marshland, woody and bare lands classes showed an increase during the study period.
