        Conservation of surface water and groundwater resources needs to be applied appropriate strategies and policies in this context that more understanding of farmers' behavior is vital. Therefore, in present study used of positive mathematical programming (PMP) and production function with constant elasticity of substitution (CES) approach to investigate farmers' behavior in surface water and groundwater usage and determination the appropriate policy programming to conservation of Qazvin plain water resources. The investigated strategies include increasing the price of irrigation water and reducing the availability water resources that each under the various scenarios was investigated. The required data in this study are related to year 2011-2012 that by referring to the relevant departments in Qazvin province was collected. The results showed that each two investigated approaches in this study leads to saving irrigation water, but the changes mean of gross margin by applying the availability water reducing policy and increasing the price of irrigation water policy 15.94 and 27.61 percent decrease respectively. The economic irrigation water productivity also in condition of above policy implementation changes of 0.435 to 0.331 and 0.434 to 0.230 the thousands of cubic meters respectively. Therefore, the reducing water availability policy according to the less reduction of the gross margin resulting from cropping pattern and more economic water productivity was proposed to conservation of Qazvin plain surface water and groundwater resources.

        In the present study first the agricultural production functions was estimated based on three techniques of  full irrigation and deficit irrigation 5 and 10 percent in order to presentation of the practical solution to conservation of surface and underground water resources in Qazvin plain. The optimal amounts of cropping pattern were determined in Qazvin province by a non-linear programming model. Then, the effects of deficit irrigation was investigated on cropping pattern, water used and farmer’s gross marginal simultaneously with reduced available water under scenarios 10, 20, 30 and 40 percent. To estimating of the agricultural production functions was used Ordinary Least Squares method and Eviews software. The non-linear programming model was solved in GAMS software. The results of estimated production functions showed that deficit irrigation 5 percent creates a slight decrease in products yield. But, deficit irrigation 10 percent has the negative effect on yield of most products. The results of non-linear programming model showed although use of deficit irrigation 5 percent simultaneously with reduced available water policy creates the slight decrease in farmer’s gross marginal but this technique helps to maintain and sustainability of surface and underground water resources of Qazvin plain strongly.

        Nowadays, constructive activities such as dam construction, villages and cities development and etc. are some of the main human factors in destroying many of archaeological sites. By the same token, during road construction in Buin Zahra- Sagz Abad, transit axis widening project in Qazvin province, southern parts of Maya tepe which have been located in road boundary would be destroyed. Therefore, urgent excavation of mentioned site was implanted in fall 1389 by an archaeological expert of cultural heritage organization of Qazvin city. Maya tepe is located in 5/5 km of the west of Buin Zahra City and in northern side of Buin Zahra- Sagz Abad axis and is an important site due to its particular location which is near to prehistoric sites of Qazvin plain such as Charbone, Zagheh, Ghabrestan and Sagz Abad. During the excavation in 10 trenches 2×2 meters and with preliminary researches about obtained results specially ceramic typology, within a semi-permanent settlement pattern, this site has a culture from late Neolithic I and early late Neolithic II (end of the first half of the sixth millennium BC), whose similar cultures in Qazvin plain have been identified in Charbone and Ebrahim Abad sites. In this paper, findings and results of an urgent excavation are presented and ultimately a comparative chronology of Maya Tepe is presented. Manuscript profile

        Ever since man succeeded in discovering metal and realized its value, this industry has always played an important role in the course of human life, and man has tried to solve many of his problems by using it as much as possible. Due to the importance of this industry and its progress and development, the period of metal use has been divided into three shorter stages of copper, bronze and iron. The environmental conditions for the emergence of metallurgy and metal industries in the semi-arid plains of the Iranian plateau have been very suitable, because in these areas there are various and abundant minerals that are still exploited. The proximity of these mineral resources to ancient sites has provided a good base for the extraction and production of metals in the ancient period. One of the important areas of Iran, which is very important in this field and studies have been done in this field so far, is the Qazvin Plain, which we will examine in this article.

        Tepe Sagzabad is one of the most important Prehistoric Sites in Qazvin Plain. Based on the long time Department of Archaeology, University of Tehran excavation, Tepe Sagzabad Known as a best sample of Iron and Late Bronze Age site in Qazvin Plain. Some new evidence of late 4th Millennium BC Cultures is Known Late Chalcolithic Period in Central Plateau, Has been identified in Tepe Sagzabad. Research-based Training Excavation [Practical method of excavating projects] was carried out in the fall of 2008 by the Department of Archaeology, Tehran University, intending to study the layers of the late chalcolithic discovered in 2007. In this season three trenches (6, 7 and 8) were dug. At last, the evidence of the late chalcolithic was only found in trench 6. Unfortunately, the expedition couldn’t find any complete structural [architectural] remains due to illegal digging, but a considerable number of pottery sherds typical of this period, were found. This article will only focus on the typology, classification and various types of the late chalcolithic pottery. Manuscript profile

        Trying excavation of department of Archaeology of university of Tehran in Qazvin plain at Tape Sagzabad carried out in autumn 2009 and two small Trenches (7&8) with stratigraphic aims at south part of the site were excavated. Unfortunately, cultural layers of Tape Sagzabad have been badly damaged, due to illegal excavation, but the south part of the site seemed to be safer from the destruction. The cultural layers of this part especially in Trench 7 presented logical and regularly cultural sequence. In this Trench the evidence of historical period, Iron Age and late Bronze Age was found, but because of the small excavated area of excavation (just 2×2 m. dimension) we could not find any structure. However, the pottery evidence of the Trenches provided the possible offers of relative chronology of this part of the site. The thickness of the cultural layers of this part, especially in Tranche 7, presents a large extent of the site in the south part showing the necessity of determination excavation for the Tape Sagzabad. This paper focused on typology, classification, presentation and comparison of the different kinds of the potteries comming from of those two stratigraphic Trenches and we will try to present the relative chronology of south part of Tape Sagzabad.  Manuscript profile

        Identifying acceptable drinking water sources depend on the methods which always incorporate the correct and logical choices. One of these methods is combination of Analytical Hierarchy Process (AHP) and Geographic Information System (GIS), which is one of the appropriate assessment tools for groundwater management. The main objective of this study is to evaluate groundwater quality for drinking purposes in Qazvin plain. In order to build the groundwater quality map of this area, water quality parameters of 17 wells including total dissolved solids, hardness, sodium, chloride and sulfate during 2013 was measured. At the first step, the zoning map parameters were drawn by Interpolation method, Inverse Distance Weighted (IDW), then classifications of maps were prepared based on Schoeller method. Afterwards the weights of the parameters were determined with the help of AHP. In the final stage, groundwater quality map of the study area was created by multiplying their combined weights to related zones. The results showed that about 83 percent of the area water quality is good and acceptable and about 17 percent is inappropriate. It could be concluded that most of the water in the study area in the Qazvin plain has good quality while central and eastern parts have more drinkable water sources. Manuscript profile

        Groundwater is the most important source for various uses, including drinking and farming requirements. In Qazvin plain region the existence of these resources such as springs are very important for livelihood and consumption of the region’s population. In this study, fifteen springs were sampled in 2013. The aim of this study was to evaluate water quality of springs in the north region of Qazvin plain for drinking and agricultural purposes. For this purpose, for classification of water quality for drinking water, the Water Quality Index (WQI) method and for agricultural water usages, Wilcox classification, sodium percentage and RSC was used. The results indicated that among springs evaluated, based on the WQI method, about 93 percent of them were categorized in good and excellent range and about 7 percent in poor range. Based on Wilcox classification, about 80 percent of samples were categorized in the range of low salt level suitable for agriculture (C2S1), and 20 percent were categorized as salty and should only be used when necessary(C3S1). The classification based on the percentage of sodium, showed that about 80 percent of the samples examined were in excellent, good and acceptable conditions and 20 percent were in uncertain status. Similarly, according to RSC rankings, about 93 percent had acceptable quality, and 7 percent had poor quality. In general, according to the results of classification of this study area, springs were suitable and favorable for drinking and farming purposes and a few need further monitoring and investigation.

        Groundwater has become the most important natural resource in recent years due to lack of rainfall and less surface water. In this Study, the effect of geological and agricultural activities on groundwater resource area in north of Qazvin Plain has been studied. For this research to study the qualitative parameters, 17 wells were sampled in 2013. Initially for estimation of the impact of geology on groundwater samples, water type and saturation index (SI) of various minerals were studied, then the impact of human factors on groundwater resources in the North of Qazvin plain was investigated by using linear regression analysis. Results showed that the amount of dissolved minerals from the west to the east of the study area is on the rise. Ions of sodium, bicarbonate and sulfate are dominant ions, mostly as a result of the dissolution of halite, gypsum and carbonate which entered the groundwater. Linear regression analysis showed that high correlation of nitrate, sulfate, chloride, potassium, and total dissolved solids (TDS) reflects the impact of agricultural activities on groundwater. Nitrate concentration was found to be much higher than WHO 2011 standards (50 ppm) in western (335 ppm) and eastern (103 ppm) parts of study area as a result of agricultural activities.
