Climate change could potentially alter the hydrologic cycle processes, such as precipitation, which affect surface runoff, temperature and relative humidity and are closely related to evaporation and streamflow in water bodies and evapotranspiration from plants. An ensemble of data composed of a baseline (base climatology) of the 19611990 model and climate projections were run (from 2025 to 205...

Water resources provided by alpine glaciers are an important pillar for people living in the arid regions in the west of China. In this study, the HBV (Hydrologiska Byrans Vattenavdelning) light model was applied to simulate glacier mass balance and runoff in the Koxkar River Basin (KRB) on the south slope of Mt. Tumur, western Tianshan Mts.. Daily temperature and precipitation were calculated ...

abstract recent global warming has led to a change in the global hydrological cycle and an increase in extreme events such as flood and drought at the global and continental scales. however, at the regional scale, the magnitude of warming and the resulting changes in water resources are different from one region to another. unlike air temperature whose increase is evident throughout the world, ...

recent studies in scientific education as well as foreign and second language instruction suggest that thinking has rarely been an integral part of education and training in classroom. some scholars decried the lack of emphasis on thinking in the institutes and schools. they noted that memorization and drills were rewarded,while inquiry, reflection, and consideration of alternatives were frowne...

Understanding the variations of streamflow of rivers is an important prerequisite for designing hydraulic structures as well as managing surface water resources in basins. An overview of the impact of climate change on the streamflow in the Hablehroud River, the main river of a semi-arid basin in north-central Iran, is provided. Using the LARS-WG statistical downscaling model, the outputs of Ha...

although precipitation is the most important factor which effects rangeland production, but there is little information on the relationship between production and the interactions of climatic factors and specially drought indices. .in this research, the relation between production and climatic factors of rainfall, temperature, evapo- transpiration, and as well as drought indices of standardized...

abstract pragmatics is the study of communicative action in its sociocultural context. communicative action includes not only using speech acts (such as apologizing, complaining, complimenting, and requesting), but also engaging in different types of discourse and participating in speech events of varying length and complexity. the present study aimed to investigate the assessment of pragm...

within the climate change debate and its probable impacts on water resources systems, design and operation of management plans based on the assumption of stationary hydrology may cause serious challenge to accurately predict future supplies. therefore this case study is trying to assess trend in hydroclimatic variables of karkheh rivers upstream by applying modified mann-kendall trend test on l...

abstract: since sugar consumption is directly related to diabetes and other illnesses such as obesity, the issue that will most heavily dominate the health food market is blood sugar management and low glycemic foods. using calcium chloride and gums such as sodium alginate and low ester pectin as thikener and a high-potency sweetener aspartame we were able to reduce sugar content of sour cherry...

We used remotely sensed weekly snow water equivalent (SWE) and snow cover extent (SCE) data to investigate streamflow response to seasonal snowcover change over the Yukon watershed. We quantified the seasonal cycles and variations of snowcover (both SWE and SCE) and river streamflow, and identified a clear correspondence of river discharge to seasonal snowcover change. We also examined and comp...
