excessive withdrawal of groundwater and reduced rainfall in recent years have caused the drawdown of groundwater table. therefore, it is necessary to manage it for preventing its damage. the present study was carried out to investigate the effect of increasing the irrigation efficiency on groundwater fluctuation on ajab-shir plain aquifer. the aquifer was simulated by using visual modflow 3.1 s...

The relationship between topography, land use, and topsoil moisture storage is investigated for a small catchment with undulating deep loess hilslopes in the south of the Netherlands. For a period of 10 months, soil moisture profiles have been measured weekly at 15 locations throughout the catchment. A Generalized Additive Model was employed to find relationships between the various factors inf...

[Purpose] This research was designed to find out how the so-called "dynamic balance" is affected by doing different types of warm up exercises. In particular, the research is focused on the difference in the effect on dynamic Balance of warming up in water versus on the ground. [Subjects and Methods] Twenty healthy adults were the subjects of this study, with 10 people assigned each to two grou...

in tunisia, kalâat el andalous irrigated district is one of the most affected areas by salinization. the objective of this study was to predict the root zone salinity (over 10 years) in this area using the saltmod simulation model for subsurface drainage system. saltmod is based on water balance, salt balance model, and seasonal agronomic aspects. in the pilot area, irrigated vegetables crops s...

introduction water quality refers to the chemical, physical and biological characteristics of water. it is a measure of the condition of water relative to the requirements of one or more biotic species and or to any human need or purpose. it is most frequently used by reference to a set of standards against which compliance can be assessed. the most common standards used to assess water quality...
