The approach integrates machine learning algorithms, including artiﬁcial neural networks (ANN), support vector regression (SVR), and multivariate linear regression (MLR), on a single platform. The study area was analyzed by extracting watersheds from a Digital Elevation Model (DEM) and calculating eight morphometric indices. The morphometric parameters were normalized using fuzzy membership functions to improve accuracy. The performance of the machine learning algorithms is evaluated by mean squared error (MSE), mean absolute error (MAE), and correlation coefﬁcient (R2 ) between the output of the method and the actual dataset. The ANN model demonstrated high accuracy with an R2 value of 0 .974, MSE of 4 .14 􀀂 10􀀀6, and MAE of 0 .0015. The results of the machine learning algorithms were compared to the tectonic characteristics of the area, indicating the potential for utilizing the ANN algorithm in similar investigations. This approach offers a novel way to assess watershed morphometry using ML techniques, which may have advantages over other approaches.  \nKeywords: watershed morphometry; fuzzy analytic hierarchy process; artiﬁcial neural networks; support vector regression; multivariate linear regression; tectonics; Makran  \n1. Introduction  \nWatershed morphometry is a crucial factor in determining the impact of tectonic processes on the landscape. By analyzing the shape and geometry of watersheds at a regional scale, we can identify the relative signiﬁcance of tectonic deformation versus erosion in landscape evolution [1,2] . Understanding the impact of these geological forces on the morphology of watersheds and the development of drainage systems is essential, as it can have implications for sediment supply to river reaches and increase the risk of landslides [3] . Furthermore, by quantifying the morphotectonic situation of watersheds, we can gain insight into their evolution and assess the role of regional tectonic control in shaping their development [2,4–6] . Recent studies (e.g., [7–10]) have expanded our understanding of the rel","cbCaikHr8slmOVTW","https://ap.wps.com/l/cbCaikHr8slmOVTW","pdf",3145000,1,19,"English","en",105,"# Introduction\n## Watershed
