Drought as a natural but temporary imbalance of water availability is the interaction between natural environment and human life resulting in diminished water resources availability and reduced carrying capacity of the ecosystems. Drought indices are essential elements for an efficient drought monitoring system. These indices make the transforming information of climatic anomalies easier and al...
on- the-job training on of the most effective tools for managers to cope with the changing organizational environment. it grantess suitable services to customers, particularly in public service enterprises. if such training os goal oriented, planned systematically, and tailored to the employees, job content, then not only it could increase employees and organizational performance, but also it c...
Evaporation is one of the important and effective processes in water cycle that causes loss of large volumes of lake and Abbandan’s water wich its measurement has great importance in water resources planning. In this research, the amount of evaporation in six months (from April to September in 2016) from the free surface of Dazmirkande Abbandan located at Mazandaran Province has been measured b...
statistical analysis is used in hydrology where variables and processes are observed and stated in terms of numbers. the majority of hydrologic phenomena in nature, such as precipitation, runoff, evaporation, sediment transport, water quality properties, elc., are stochastic processes. however, in considering events on an annual basis, the occurence of the events may be assumed independant and ...
Enhanced production of unconventional hydrocarbons in the United States has driven interest in natural gas development globally, but simultaneously raised concerns regarding water quantity and quality impacts associated with hydrocarbon extraction. We conducted a pre-development assessment of groundwater geochemistry in the critically water-restricted Karoo Basin, South Africa. Twenty-two sprin...
let h be a separable hilbert space and let b be the set of bessel sequences in h. by using several interesting results in operator theory we study some topological properties of frames and riesz bases by constructing a banach space structure on b. the convergence of a sequence of elements in b is de_ned and we determine whether important properties of the sequence is preserved under the con...
this thesis attempts to investigate the effects of prelistening activities on enhancing iranian efl learners` listening comprehension. the present study investigated ways in which learners` background knowledge could be activated in order to enhance their l2 listening comprehension by limiting the number of possible text interpretations prior to listening. the experiments conducted in this stud...
Pakistan experiences a variety of climates ranging from a small humid patch in the north to extremely arid southern plains. Evapotranspiration is not a directly measurable element among agrometeorological parameters influencing crop growth and development. Many empirical and semi-empirical methods for estimation of crop evapotranspiration exist and are being used by individual scientists and re...
Increasing atmospheric anomalies have altered some of the extreme events such as global warming droughts, many climatic components such as precipitation, evapotranspiration, temporal and spatial distribution of precipitation, followed by dominoes of changes in freshwater resources available to communities. Human changes such as changes in the hydrological regime of rivers, changes in the qualit...
background: in this study, the chemical quality of water in some sub-basins of gamasiab river has been investigated for a long term planning of water consuming in the region . methods: the area is about 11 x10 3 km 2 , located in ramadan and kermanshah, the two western regions of iran. in this regard the results of the water samples, which were collected on the outlet of the 13 hydrometrical st...
