Estimation of Sediment Yield and Evaluation of Management Options in the Watershed Using SWAT Model

Air Soil and Water Research, Journal Year: 2024, Volume and Issue: 17

Published: Jan. 1, 2024

Land degradation and sedimentation are global issues stemming from inappropriate land management practices within watersheds, primarily due to soil erosion. The primary aim of this investigation was estimate sediment yield, pinpoint erosion-prone areas, determine effective strategies for reducing erosion yield the Mormora watershed utilizing SWAT model. performance model assessed through calibration validation procedures employing Sequential Uncertainty Fitting 2 (SUFI-2) algorithm Calibration Procedures (SWAT-CUP). conducted period 1993 2006, while carried out 2007 2013, focusing on streamflow yields at gauging station. Various metrics including R , NSE, RSR, PBIAS were used assess performance. All indicated high accuracy. average annual outlet 1.19 million t/year with a spatial 8.54 t/ha/year. About 47.33% critical areas demanding implementation conservation strategy. effectiveness five scenarios compared existing baseline conditions their in reduction. results indicate decreased by 28.3% 55.9% applying filter strips, 61.7% 68.4% grassed waterways, 71.38% terracing, 62.64% contouring, 46.3% stone/soil bunds. Ultimately, terracing emerged as most strategy mitigating study area. Consequently, research outcomes developed methodology serve valuable resource decision-makers, experts, researchers involved sustainable management.

Modeling of Water Resource Dynamics in SUR Systems Through Generalized Conformable Calculus in Arid Sites in Mexico

Water, Journal Year: 2024, Volume and Issue: 16(24), P. 3691 - 3691

Published: Dec. 21, 2024

In this work, we present a comprehensive extension of the Surface–Underground–Recharge (SUR) water supply model through incorporation generalized conformable derivatives. This operator enables capture more exotic dynamics within system, enhancing modeling framework's ability to simulate complex hydrological interactions. Additionally, extend results restricted phase spaces analyzed dynamical systems, facilitating deeper qualitative analysis. To achieve this, augment dimension SUR rendering it an autonomous higher-order system. Furthermore, introduce novel function, referred as linear combination which significantly broadens scope our capabilities. Thus, study contributes advancement modeling, providing robust tool for analyzing intricate resource in specific regions.
