چکیده مقاله :
در تحقیق حاضر میزان تولید روان آب و رسوب حاصل از بارندگی ایجاد شده از دستگاه باران ساز (با شدت 52 میلیمتر در ساعت و با دوره بازگشت 20 ساله) در حوزه آبخیز لاویج مورد بررسی قرار گرفته است. بدین منظور پس از تهیه نقشه های طبقات شیب، لیتولوژی، ژئومرفولوژی و کاربری اراضی- نقشه واحدهای کاری بدست آمد و در هر واحد کاری به تعداد3 نمونه خاک و سه نمونه از روان آبو رسوب بدست آمد و تجزیه تحلیل های آزمایشگاهی انجام شد. نتایج نشان داد که حداکثر مقدارروان آبدرواحد کاری شماره 15 با کاربری مرتع حاشیه روستا و طبقه شیب 15 تا 30 درصد و حداکثر مقدار رسوب در واحد کاری شماره 10 با کاربری مرتع حاشیه روستا و طبقه شیب 15 تا 30 و سازند شمشک بوقوع پیوسته است. همچنین کمترین مقدار روان آبو رسوب در واحدکاری شماره یک با کاربری مرتع حاشیه روستا و طبقه شیب 12 تا 15 درصد و سازند الیکا ایجاد گردیده است.
In this study Run off and sediment generated from rain fall simulator was investigated in lavij watershed. In this order٬slope-Lithology- geomorphology and Land use maps were intersected and then, work units map was prepared. Then, in each Work unit's tree run off and sediment sampling was created by Rainfall simulator. Results show that٬ the Maximum potential of runoff generation was approved ٬in work unit of number fifteen with range land and 15-30% slop, also the Maximum potential of Sediment suspended production was approved ٬in work unit of number teen with range land and 15-30% and shemshak formation. The minimum run off and suspende sediment production were approved in work unit number one with range land and 12-15% and Elika formation.
