In the present study, streamflow simulation capacities between Soil and Water Assessment Tool (SWAT) Hydrologic Engineering Centre-Hydrologic Modelling System (HEC-HMS) were compared for Huai Bang Sai (HBS) watershed in northeastern Thailand. During calibration (2007–2010) validation (2011–2014), SWAT model demonstrated a Coefficient of Determination (R2) Nash Sutcliffe Efficiency (NSE) 0.83 0....
the community dynamics of aquatic coleoptera(insecta)in one of the spring-stream habitats of bammo national park in fars province called cheshmeh-ye-ghanbari is studied as a pilot project and model for acquaintance with and furthering the biodiversity studies on fauna of iran. sixteen species-populations out of nineteen of this community were already identified for their taxonomy and for thei...
محدودیتهای ساختاری مدلهای هیدرولوژیکی و عدم دسترسی به همة پارامترهای حوضة آبخیز همچنین عدم امکان تعیین دقیق شرایط مرزی و شرایط اولیه، واسنجی مدلهای هیدرولوژیک را ایجاب میکند. با توجه به زمانبربودن واسنجی دستی، بهویژه هنگامی که دادهها کم و پارامترها فراواناند، روشهای واسنجی خودکار، مبتنی بر استفاده از روشهای جستوجوی سیستماتیک در فضای چندبعدی، با استفاده از یک تابع هدف، بسیار سودمند ا...
چکیده روش های متعددی برای برآورد رواناب حاصل از بارش در حوضه های آبریز وجود دارد. یکی از این روش ها استفاده از مدل های هیدرولوژیکی است. با استفاده از مدل های هیدرولوژیکی و شبیه سازی فرآیندهای هیدرولوژیکی می توان با صرف کمترین زمان و هزینه، رواناب و مولفه های دیگر چرخ? هیدرولوژیکی را برآورد کرد. از آنجا که در حوضه های آبریز اندازه گیری تمام کمیت های مورد نیاز برای تحلیل رواناب ممکن نیست، انتخاب...

abstract translation has become a cultural act which plays a significant role in human life. with the emergence of functional translation theories, and skopos theory in particular, translation has been considered as a purposeful, interpersonal and intercultural activity which is produced for particular recipients and directed by a specific purpose. this purpose determines the translatio...
For modeling, the concept of the system and the system boundary is necessary. The system is defined as a group of objects that in order to fulfill a specific purpose in the framework relationship or interdependence of regularly are interconnected. Systems rainfall - runoff from rainfall in the basin is started and after applying the types of losses (evaporation, infiltration, etc) it will beco...
seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
although there are studies on pragmatic assessment, to date, literature has been almost silent about native and non-native english raters’ criteria for the assessment of efl learners’ pragmatic performance. focusing on this topic, this study pursued four purposes. the first one was to find criteria for rating the speech acts of apology and refusal in l2 by native and non-native english teachers...
