drought is transient phenomenon , slow , repetitive and integral part of the climate of each region. drought begins with a substantial reduction in precipitation over the long-term average rainfall and over time, reduced soil moisture and surface and ground water resources will continue to decrease. this phenomenon is the most important in bakhtegan basin because of its importance in strategic ...

rivers and runoff have always been of interest to human beings. in order to make use of the proper water resources, human societies, industrial and agricultural centers, etc. have usually been established near rivers. as the time goes on, these societies developed, and therefore water resources were extracted more and more. consequently, conditions of water quality of the rivers experienced rap...
the goal of this research is the determining of planting date and providing agricultural calendar for corn in kermanshah province using climatic elements of temperature and rain fall. so, at first, long term climatic statistics are collected from 2001 to 2011 and then considered to temperature and rain fall parameters like absolute maximum and minimum in region during growth period, planti...
All over the world, farming communities need to adapt a changing climate. At same time, they are confronted by necessity increase food availability for growing population, but also ensure sustainable use of natural resources. In this process, agriculture is not just fiend responsible an in greenhouse gas emissions, nor victim rising temperatures and extreme weather events. Agriculture ally clim...
The scalar flux–gradient relationships of temperature (φT ) and specific humidity (φq ) under unstable conditions are investigated using eddy-covariance measurements of air– sea turbulent fluxes and vertical profiles of temperature and specific humidity collected from a marine meteorological platform. The gradients of temperature and specific humidity are obtained frommeasurements at five heigh...
In a climate change scenario, successful modeling of the relationships between plant-soil-meteorology is crucial for a sustainable agricultural production, especially for perennial crops. Grapevines (Vitis vinifera L. cv Chardonnay) located in eight experimental plots (Burgundy, France) along a hillslope were monitored weekly for 3 years for leaf water potentials, both at predawn (Ψpd) and at m...
