Wheat is one of the most important strategic agricultural products which is crucial in providing food for the people of our country. The aim of this study was to assess the performance of AquaCrop plant simulation model, as one of the newest models, in determining the yield and planting date of rainfed and irrigated wheat in Kermanshah province. For this purpose, the rainfed and irrigated wheat yield was simulated by AquaCrop model using daily climatic data of five synoptic stations, including precipitation, maximum and minimum temperatures, potential evapotranspiration, wind speed and sunshine hours in a 22-year (1992-2013) period, as well as other environmental information. Among the dates entered to the model, the date that had the highest yield was selected as the best planting date. The results showed that from the point of view of yield, Ravansar and Sarpole-Zahab plains are more susceptible for planting rainfed and irrigated wheat, respectively. Wheat yield showed great sensitivity to changes in planting date. Planting dates in the stations were proposed from October 10 to November 20 for rainfed wheat, and from October 10 to November 10 for irrigated wheat, that match well with the actual dates of planting in the region. In general, AquaCrop model well simulated the different stages of growth and yield of rainfed and irrigated wheat according to the climatologic conditions of Kermanshah Province, and therefore could be an important tool to evaluate the potential wheat yield in the province and other regions with similar climates.

Suitable climate is a natural resource and economic wealth for tourism. It also can be considered as an element which provides some attractions for tourists and thereby can increase the number of tourists and satisfaction. All climate elements are involved in the health, comfort, entertainment and tourist attraction, but some elements such as temperature, relative humidity, sunshine and wind are more important which were studied in this article to indicate the effect of thermal comfort in Tourism attraction in the cities of the Sabalan hillside, which due to their geographical position can be considered as a valuable potential for the development of tourism. This research was a descriptive – analytic one and data collection was done through a library method. In this study, the data and climatic data were collected during the period of 1981-2010 to study the tourism potentials in the Sabalan region. Tourism climate index TCI (Mieczkowski) was used to analyze the data, this index shows climate Tourism for each month of the year in the form of numerical and descriptive index. The results showed that the months of June, July, August and September due to providing best welfare conditions for tourism were the ideal ones. The months of January, February, March, April, November and December had low importance and were in acceptable level but were not so good for tourists. The months of May and October had average conditions for tourism activities. Overall, the best months of the year, June and September and worst months were December, January and February for tourism activities in the cities of the Sabalan hillside.
