Investigation of drought event has a great importance in the natural resources and water resources management and planning. In this research, the effect of the climate change on drought characteristics in Khoy station was investigated using the HadCM3 model under B2 scenario. The statistical downscaling was executed using SDSM 4.2.9 and observed daily precipitation, observed predictors and...

Due to the competition for water resources, increasing efforts are done in order to use more efficiently irrigation water in agriculture. The purpose of this paper is to find out daily soil water content (SWC) dynamics during depletion cycles in order to emphasize its pattern and compare daylight vs. night (dark) and morning vs. afternoon SWC dynamics in an irrigated peach (Prunus persica [L.] ...

Groundwater depletion in the face of growth is a well-known problem, particularly in those areas that have grown to become dependent on a declining resource. This research comprises a broad synthesis of existing water resources data, to understand the long-term implications of continued growth in water demand on groundwater dominant water resources, and to develop a tool for sustainable water m...

The problems and present methods for the calculation of monthly and annual effective infiltration coefficients in Dinaric karst catchments which cover areas smaller than 200 km are discussed. An example is given of the catchment of the Gradole karst spring, which covers 114 km. The climate on the catchment is North Mediterranean, with average annual rainfall of 986 mm, average air temperature o...

In this paper, an organization having two grades in which depletion of manpower occurs at every decision epoch is considered. Using univariate max policy of recruitment, based on shock model approach mathematical model is constructed. It is assumed that the system has constant combined threshold and the inter-decision times are exchangeable and constantly correlated exponential random variable....

How does technological change affect the depletion of non-renewable natural resources? We argue that to answer this question it is necessary to account for the interaction between skill-biased technological change, population dynamics and their effects on natural resource use. Skill-biased technolgical change leads in a non-malthusian world to a decline in the long-run growth rate of the popula...

investigation of drought event has a great importance in the natural resources management and planning water resources management. in this research, the effect of the climate change on drought characteristics in northwest of iran was investigated using the hadcm3 model under a2 scenario. the statistical downscaling was executed using sdsm 4.2.9 and observed daily precipitation, observed predict...
