The knowledge on the spatial distribution of soil available water capacity at a regional or national extent is essential, as soil water capacity is a component of the water and energy balances in the terrestrial ecosystem. It controls the evapotranspiration rate, and has a major impact on climate. This paper demonstrates a protocol for mapping soil available water capacity in South Korea at a f...

In the context of agricultural nitrogen excesses in northwestern France, pyrite-bearing weathered schist aquifers represent important hydrological compartments due to their capacity to eliminate nitrate (NO3-). Under oxygen-free conditions, nitrate is reduced simultaneously with the oxidation of pyrite leading to the release of sulfate (SO4/2-). The aim of the present study is to identify the h...

decline in postharvest losses of kiwifruit depended to maintain of quality characteristics during storage and transportation. storage losses caused serious economic losses in kiwifruit. this study was conducted to inhibition of pathogen infection and increasing fruit quality of kiwifruit. hayward kiwifruits inoculated by b.cinerea conidia through pore wounds which formed by removal of the pedic...

The hydrogeological system of an ecologically sensitive alpine floodplain in the Valle di Blenio, Switzerland, was investigated using hydrochemical and 3H-3He dating methods. Water samples from six wells and from different surface locations were analyzed. The analysis of the concentrations of major ions in conjunction with age determination by the 3H-3He-method allowed the main hydrological pro...

In the 1970s, the word ‘‘hydroschizophrenia’’ was used to describe the attitude of decision makers, who played down the role of ground water relative to surface water resources. More than 30 years later, this situation has not changed. Take as an example the Ministerial Declaration signed by more than 100 ‘‘Water Ministers’’ at the Third World Water Forum (Kyoto, March 2003) in which ground wat...

In arid regions, human activities like agriculture and industry often require large ground water extractions. Under these circumstances, appropriate ground water management policies are essential for preventing aquifer overdraft, and thereby protecting critical ecologic and economic objectives. Identification of such policies requires accurate simulation capability of the ground water system in...
