چکیده
شناخت رفتاری رودخانه و انجام فعالیتهای سازگار با طبیعت آن و اقدامات مهندسی مناسب همواره دغدغه مهندسین درگیر در این رشته بوده است. هدف اصلی این مقاله ارائه طرح جامع ساماندهی رودخانه کشف رود مشهد حد فاصل تصفیه خانه پرکندآباد تا تصفیه خانه اولنگ بدلیل اهمیت بسزای این رودخانه در این بازه می باشد. جهت افزایش صحت و دقت داده ها در انجام مطالعات از تکنولوژی GIS و نرم افزارهای رقومی بهره گرفته شده است، بطوریکه پارامترهای فیزیوگرافیک با استفاده از لایه های رقومی با دقت 250000: 1 در نرم‌افزارهای ArcGIS و ArcView مورد تجزیه و تحلیل و برآورد قرار گرفت. در حد فاصل تصفیه خانه پرکند آباد تا انتهای محدوده مطالعاتی به دلیل مساعد بودن جمیع شرایط جهت کشاورزی و برداشت محصولات جالیزی، زمینهای اطراف رودخانه از ارزش ویژه ای برخوردار هستند و به همین دلیل پیشروی های آشکاری به بستر و حریم رودخانه مشهود است. بر اساس نتایج بدست آمده ارتفاع دیوار سپری در بالادست 1.75RS و برابر با 5/3 متر و ارتفاع دیوار سپری پایین دست 2RS و برابر با 4 متر بدست آمده است. با توجه به ملاحظات سازه ای در افزایش لنگرهای انتهایی حوضچه آرامش با افزایش عمق سپری، ارتفاع سپری بتنی 5/1 در نظر گرفته شده است و دیوار سپری سنگ و ملاتی به ارتفاع 5/2 متر در انتهای سپری بتنی طراحی گردید. نتایج نشان داد که بیشترین مقدار سرعت جریان در دبی 25 ساله در رودخانه کشف رود برابر 6/2 متر در ثانیه می باشد. در طول رودخانه کشف رود براساس ارتفاع تراس های شکل گرفته در حاشیه رودخانه و مطالعات فرسایش صورت گرفته در رودخانه 4 کلاس فرسایشی تشخیص داده شد. مناطقی از رودخانه که آثار فرسایش کناری رودخانه ای در آن محل بیش از 50 درصد می باشد به عنوان مناطق مناسب جهت اجرای ژئوتکستایل پیشنهاد گردید.

Abstract
Understanding the river behavior and the activities compatible with their nature and suitable engineering activities are always the main concerns in agricultural sciences. The main purpose of this paper is the presentation of comprehensive plan for organizing and betterment in Kashafrud RiverbetweenParkand-abad wastewater treatment and Olang wastewater treatment due to the value of this river in this location. So, by using the GIS technology and digits software the physiographic parameters are analyzed in Arc-view and Arc-Gis in 1:250000 scale. The distance between Parkand-abad wastewater treatment to the end of the studied area because of the best condition in all aspect for farming and potager’s products the agricultural land is valuable, so there are clear human activities in riparian which is critical. Based on the result of the anchored wall in upstream is 1.75RS and equal to 3.5 m and the anchored wall in downstream is 2RS and equal to 4 m. In order to the structural consideration in the increase of stilling basin in distal anchors with increasing the depth of them are considered 1.5 in height and stoned anchored wall is designed 2.5 m. the results are shown that the maximum amount of 25 years discharge in Kashafrud River is 2.6m/s. Across the river based on terraces in riparian and the erosional river studies in this river, four classes are determined. The area of river which erosion bank more than 50 percent is suggested the best site for implementation of geotextile.
