Surface Flow Routing using Kinematic Wave and Time – Area Methods for Upstream Watershed of the Bustan Dam in Golestan Province, Iran

This study aims to evaluate two methods of surface water routing including kinematic wave and time-area in upstream of the Bustan dam. To this end, first considering the features and application prerequisites of both methods and describing the hydraulic and hydrologic conditions within the Tamer watershed, algorithms and scripts of kinematic wave and time-area methods were developed. Then the s...

evaluation of base flow separation methods based on recession analysis

hydrograph analysis is a complex problem in a variety of water resources investigations and its estimate is critical in the assessment of low flow characteristics of river for use in water supply, water management and pollution assessment. the paper describes different methods of base flow separation based recession analysis from daily river flow records and distinguishes the most suitable meth...

the effect of traffic density on the accident externality from driving the case study of tehran

در این پژوهش به بررسی اثر افزایش ترافیک بر روی تعداد تصادفات پرداخته شده است. به این منظور 30 تقاطع در شهر تهران بطور تصادفی انتخاب گردید و تعداد تصادفات ماهیانه در این تقاطعات در طول سالهای 89-90 از سازمان کنترل ترافیک شهر تهران استخراج گردید و با استفاده از مدل داده های تابلویی و نرم افزار eviews مدل خطی و درجه دوم تخمین زده شد و در نهایت این نتیجه حاصل شد که تقاطعات پر ترافیک تر تعداد تصادفا...
