lack of fire behavior studies and the immediate needs posed by the extent of the fire problem in forests of iran require that extensive studies be conducted to develop models to predict fire behavior in the region.in this study, farsite fire area simulator was applied to simulate spread and behavior of two real fires that had occurred in northern forests of iran during 2010 summer and fall seas...

Saffron is an important crop in social and economical aspects in Khorassan Province (Northeast of Iran). In this research we tried to evaluate trends of saffron yield in recent years and to study the relationship between saffron yield and the climate change. A regression analysis was used to predict saffron yield based on 20 years of yield data in Birjand, Ghaen and Ferdows cities. Climatologic...

Part of the charge to the WRF Research Applications Board (RAB) is to “review trends and emerging science and technologies and to identify and prioritize those elements representing the greatest opportunities for advancing the capabilities of the WRF modeling system for use by the research community.” In response to this directive, the RAB has solicited input from the research community and pre...

We evaluate the impact of climate change on stream flow in the Upper Mississippi River Basin (UMRB) by using a regional climate model (RCM) coupled with a hydrologic model, the Soil and Water Assessment Tool (SWAT). The SWAT model was calibrated and validated against measured stream flow data using observed weather data and inputs from the Environmental Protection Agency’s BASINS (Better Assess...

The objective of this paper is to provide an overview of the HybridMaize software (www.hybridmaize.unl.edu, verified 28 Feb. 2006), with emphasis on its practical applications based on our own experience and feedback from users. The Hybrid-Maize model is a computer program that simulates the growth and yield of a corn crop (Zea mays L.) under nonlimiting or water-limited (rainfed or irrigated) ...
