abstract the goal of this survey is to prepare the dry land wheat atlas for zanjan province, according to the climate data. so we can recognize which areas are susceptible and to understand climate capabilities and limitations for dry land wheat. for reaching this purpose first raining and temperature datas of the research region were gathered and analyzed. at the first stage, proper according ...

Modeling potential evapotranspiration (ET0) is an important issue for water resources planning and management projects involving droughts flood hazards. Evapotranspiration, one of the main components hydrological cycle, highly effective in drought monitoring. This study investigates efficiency two machine-learning methods, random vector functional link (RVFL) relevance machine (RVM), improved w...

To address devastating land desertification and soil erosion and to improve human well-being, central government in China has implemented a number of ecological restoration programs. It is essential to rigorously monitor the dynamic of vegetation activity and evaluate the effectiveness of these programs, not only to provide scientific support for ecosystem monitoring in arid and semi-arid regio...

Identification of climatic indices are vital in essence of their ability to characterize different climatic events. We focus on discovery of climatic indices important for Indian summer monsoon from climatic parameters surface pressure and zonal wind velocity. We use climatic network based community detection approach for discovery of climatic indices. New indices depict better correlation with...
