In the past, rock slope stability analysis were performed either graphically or using a hand-held calculator, but nowadays there are variety of slope stability analysis which can be used according to the field condition and potential failure mode. In 2-D analysis, effect of convex and concave walls are neglected, however concave slopes are believed to be more stable than straight walls due to t...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
برای محافظت از جنگل ها و مراتع در مقابل خطر آتش سوزی یکی از اولین استراتژی های که مورد توجه قرار می گیرد، تعیین مناطق مستعد وقوع آتش سوزی است. تعیین میزان خطر آتش بخشی از مدل سازی در فرایند آتش سوزی محسوب می شود؛ که بیشتر جنبه های مدیریتی و کنترلی را در بر می گیرد. در تحقیق حاضر با توجه به آتش سوزی های گزارش شده در طی سال های 89-86 در اراضی طبیعی استان چهارمحال و بختیاری مهمترین عوامل تاثیر گذا...
