| شفاف‌سازی تغییرات عرضه‌ی موادمعلق در مقیاس‌های زمانی برای برنامه‌های مدیریتی ضروری است. در این پژوهش تغییرات انتقال مواد معلق در مقیاس‌های زمانی در رود ماربره‌ی دره‌تخت، لرستان بررسی شد. چهار دیدگاه آستانه‌ی فصلی، فصلی، سالانه و دوره‌ی کاربری زمین بر اساس داده‌های اندازه‌گیری‌شده‌ی 95–1350 با استفاده از روش‌های آماری تحلیل شدن. آب‌دهی آستانه‌ی فصلی با استفاده از بهترین توزیع آماری برای دوره‌ی بازگشت 2 سال تعیین،و روابط آب‌دهی- موادمعلق برای رویدادهای بزرگ و کوچک تهیه شد. برای مقیاس کاربری زمین نیز نقشه‌ی کاربری زمین سال‌های 1377 و 1395 با فن‌آوری سنجش‌ازدور تهیه شد. براساس نتایج، بیش‌ترین ظرفیت انتقال موادمعلق مربوط به رویدادهای بیش‌تر از آستانه‌ی بهار است که شیب منحنی سنجه‌ی آن 1/469 است. تغذیه و ظرفیت انتقال موادمعلق در آب‌دهی‌های بیش‌تر از آستانه‌ی پاییز بیش‌تر از زمستان است. در دوره‌ی کاربری زمین، هرچند تغییر کاربری مرتع به د‌یم مشاهده شد، اما تأثیر سایر دخالت‌های انسانی مانند احداث 2 سد مخزنی و بندهای پرشمار در سرشاخه‌ها، منجر به کاهش میانگین انتقال موادمعلق روزانه متناسب با کاهش آب‌دهی پاییز، زمستان و بهار شده است. | ||

| چکیده [English] | ||
| Clarification of suspended load (SL) supply variations at different temporal scales is essential to provide a logical management program. In this study, the SL transport variations were investigated at different time scales in the Marboreh River, Darreh-Takht, Lorestan Province, Iran. The four seasonal, seasonal threshold, annual and land use period approaches were analyzed using statistical methods based on the collected data from 1971 to 2016. The seasonal threshold runoff was determined using the best statistical distribution for the return period of 2 years, and the SL concentration-runoff relationships were prepared for large and small events. The land use map was prepared using remote sensing data for the years 1977 and 2016. According to the results, supply and SL transport capacity were high in the large events of spring, when the slope of the sediment rating curve is 1.469. The supply and SL capacity for large events of the autumn was higher than that of the winter. In the study period, although the land use change from rangeland to dry-farming was observed, the impact of other human activities including dam construction on the tributaries has caused a decrease in the mean SL transport, corresponding with the daily runoff in autumn, winter and spring. | ||
