مدل مدیریت و ارزیابی آبی (weap) برای برنامه ریزی منابع آب توسعه داده شده است. مزیت اصلی weap، در رویکرد یکپارچه در شبیه سازی سیستم های آبی و جهت گیری آن در راستای سیاست ها می باشد. این مدل در معادلات خود، مسائل مربوط به نیاز (الگوهای مصرف آب، راندمان تجهیزات، استفاده مجدد، هزینه ها و تخصیص) را هم گام با مسائل مربوط به منابع (جریان های سطحی، آب های زیرزمینی، مخازن و انتقال های آب) لحاظ کرده است....
Assessment of climate change impact on water availability in the upper Dong Nai River Basin, Vietnam
Abstract On a global scale, climate change is projected to have detrimental impacts on water availability. This situation will become more severe owing accumulated of and anthropogenic activities. study aims investigate impact availability in the upper Dong Nai River Basin using Soil Water Assessment Tool (SWAT) Evaluation Planning (WEAP) models. Future rainfall scenarios were downscaled from f...
Abstract Background The subbasin hydrologic behaviors have been altered by many natural and anthropologic factors such as climate change land development activities. Model-based assessment can be used to simulate both hydrological processes, human-induced effects, management strategies on water resources. For the Ketar subbasin, WEAP (water evaluation planning) model was developed that aimed at...
Reduction of water resources limits the ability of farmers for food production and subsistence. Nowadays the quick growth of population has been the most important factor in the decline of renewable water. In many parts of Iran, including region of interest, the major factor in water resources decline was land use change, that may cause to ecological destruction and disruption. Sustainabl...
nowadays in trade and economic issues, prediction is proposed as the most important branch of science. existence of effective variables, caused various sectors of the economic and business executives to prefer having mechanisms which can be used in their decisions. in recent years, several advances have led to various challenges in the science of forecasting. economical managers in various fi...
The Sittaung river basin (SRB) remains one of the least studied basins Myanmar in terms assessment impact climate change. As several reservoirs already exist basin, much research is needed to understand how projected change impacts rainfall, temperature, flows, domestic and agricultural demands, hydropower generation. Given limitation observed data on ground, a combination satellite-derived met...
همراه با افزایش و توسعه روز افزون شهرها سیستم های آبرسانی پیچیده تر و برداشت از منابع موجود بیشتر می شود. از این جهت مدیریت و برنامه ریزی در بهره برداری بهینه از سیستم های موجود و بالابردن راندمان استفاده از این سرمایه های ارزشمند از اهمیت بالایی برخوردار است. شهر تهران بلحاظ موقعیت سیاسی و اقتصادی بعنوان پایتخت دارای جایگاه ویژه است و به دلیل مهاجرت افراد از نقاط مختلف ایران مدتی است دچار مشکل...
attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
A gestão dos recursos hídricos na bacia hidrográfica do rio Umbeluzi é uma questão fundamental devido ao agravamento de escassez água nos centros urbanos e agricultura que pode pôr em causa os valores socioculturais, ecológicos econômicos. Torna-se ainda mais importante o fato ser internacional, cuja demanda por tem aumentando função expansão agrícola crescimento populacional. O estudo avaliou ...
