That human knowledge, understanding and knowledge of the physical laws governing it is limited in some respects from the point of view of mathematical formulas. Numerous factors are effective in floods in the region, including topographic features, river morphology, rainfall dynamics and human activities. This research was carried out in Hableh Roud Basin. The purpose of this research is to determine the amount of runoff production of different lithology units by identifying the factors affecting sediment production through the regression model in the scale of the rain simulator. The research method is based on field studies and statistical methods. During the field visit, an experiment was performed (on the formations) with a rain simulator with a rainfall intensity of 4 mm per minute with an average rainfall of 10 minutes in three repetitions on the slope surface with a slope of 20%. For each sub-area, environmental parameters and morphometric parameters as dependent variable and runoff production as independent variables were analyzed by SPSS software using multiple regression (simultaneous and retrograde) methods. This test was applied for 21 sub-basins of Hableh River The results showed that retrograde method was the most suitable method. The adjusted coefficient increased from 58.4 in the first stage to 80.5% at the 10th stage. And the effective factors in flood are slope, environment, vegetation and lithology shows the greatest impact.</span></span></span></span><br> <span style="font-size:11pt"><span style="unicode-bidi:embed"><span new="" roman="" style="font-family:" times=""><span style="color:black"><span lang="FA" dir="RTL" style="font-family:"B Lotus""></span></span></span></span></span><br> &nbsp;</div> پارامترهای مورفومتریک, ضریب تعدیل, رگرسیون, رواناب Morphometric Parameters, Adjustment Coefficient, Regression, Runoff 131 152 http://geographical-space.iau-ahar.ac.ir/browse.php?a_code=A-10-3769-1&slc_lang=fa&sid=1 Alireza Ghodrati علیرضا قدرتی ghodrati_2000@yahoo.com 100319475328460023279 100319475328460023279 Yes Agricultural and Natural Resources مرکز تحقیقات کشاورزی و منابع طبیعی استان گیلان، سازمان تحقیقات،آموز ش و ترویج کشاورزی، رشت، ایران Alireza Hbibi علیرضا حبیبی habibi1354@yahoo.com 100319475328460023280 100319475328460023280 No Management Research Institute, River and Coastal Engineering پژوهشکده حفاطت خاک وآبخیزداری ، بخش تحقیقات مهندسی رودخانه وسواحل ایران Ali LAHIGY علی لاهیجی lahigy123@gmail.com 100319475328460023281 100319475328460023281 No Agricultural and Natural Resources مرکز تحقیقات و آموزش کشاورزی و منابع طبیعی گیلان، سازمان تحقیقات، آموزش و ترویج کشاورزی، رشت، ایران
