چکیده

در این پژوهش آب‌پایه در ایستگاه گل­گل، به‌عنوان بخشی از حوضه آبخیز سد ایلام از سال 1991 تا 2015 از جریان کل رودخانه تفکیک شد. بدین منظور روش‌های WETSPRO، فیلتر عددی یک­پارامتری و دوپارامتری برای جریان دائمی با آبخوان­های متخلخل و سنگی و با استفاده از شاخص جریان و نرم­افزار WHAT با ضرایب فیلترینگ مختلف، مورداستفاده قرار گرفتند. برای مقایسه روش‌ها و انتخاب مناسب‌ترین روش از شاخص BFI به‌عنوان آب‌پایه مشاهداتی استفاده شد. بر اساس نتایج به‌دست‌آمده، آب‌پایه بخش عمده­ای از کل جریان را به خود اختصاص داده است. به‌طوری‌که میانگین کل جریان m3/s 945/1 و میانگین شاخص جریان پایه m3/s 245/1 بدست ‌آمد که نشان از نفوذپذیر بودن آبخیز دارد. برای ارزیابی کارایی روش‌ها از معیارهای RMSE، MAE و Nash-Sutcliffe استفاده شد. نتایج نشان داد که روش Lyne and Hollick بر اساس نرم­افزار WHAT بهترین نتیجه و سپس Eckhart برای جریان دائمی با آبخوان متخلخل با سطح معناداری 742/0، میانگین m3/s 250/1، با سطح اطمینان بیش­تر از 95% بهترین نتیجه را داشتند. بنابراین، می­توان روش Eckhart را برای جریان دائمی با آبخوان متخلخل با ضریب فیلتر 990/0 به­دلیل نزدیک بودن میانگین جریان پایه در آن به میانگین شاخص جریان پایه، مناسب در نظر گرفت.

چکیده [English]

In this research, the baseflow at the Gol Gol station, as a part of the Ilam dam watershed from 1991 to 2015, was separated from the entire river flow. For this purpose, WETSPRO methods, one-parameter and two-parameter numerical filters for continuous flow with porous and rocky aquifers, and using flow index and WHAT software with different filtration coefficients were used. To compare the methods and to select the most appropriate method, BFI index was used as an observational baseflow. Based on the results obtained, the baseflow occupies a major part of the total flow. The mean of the total flow rate was 1.945 m3/s and the mean of the baseflow index was 1.445 m3/s, which indicates the permeability of the watershed. RMSE, MAE, and Nash-Sutcliffe criteria were used to evaluate the efficiency of the methods. The results showed that the Lyne and Hollick method based on WHAT software had the best result and then followed by Eckhart for continuous flow with a porous aquifer with a significance level of 0.742, mean 1.250 m3/s, with a confidence level of more than 95%. Therefore, the Eckhart method can be considered suitable for continuous flow with a porous aquifer with a filter coefficient of 0.990 due to the proximity of the mean baseflow in it to the mean of the baseflow index.
