[ 1 ] - مکان‌یابی مناطق مستعد پخش سیلاب با استفاده از منطق فازی و فرآیند تحلیل شبکه‌ای (ANP)(مطالعه موردی: دشت مشهد)
In this research, to locate and prioritize suitable areas for flood spreading in Mashhad plain, 10 criteria were used including land use, slope, alluvium thickness, distance to well, distance to subterranean, distance from the village, water table drawdown, permeability coefficient, electrical conductivity, and drainage density. Weighting process was done by Analytic Network Process (ANP) and f...
[ 2 ] - بررسی توان رسوب‌زایی و تولید رواناب در سازندهای زمین شناسی شیرکوه یزد با استفاده از شبیه‌ساز باران
One of the main sources of runoff in arid and semi-arid mountainous highlands is typically composed of before Quaternary formations. Since the structure and lithology of formations are different, varying formations can have different significance in terms of runoff and sediment. The present study aimed to investigate the sediment production potential and the runoff generation threshold on three...
[ 3 ] - ارزیابی عملکرد سه روش طبقه‌بندی تصویر (جنگل تصادفی، ماشین بردار پشتیبان و بیشترین شباهت) در تهیه نقشه کاربری اراضی
Land use/cover maps are the basic inputs for most of the environmental simulation models; hence, the accuracy of the maps derived from the classification of the satellite images reduces the uncertainty in modeling. The aim of this study was to assess the accuracy of the maps produced by machine learning based on classification methods (Random Forest and Support Vector Machine) and to compare th...
