Gully erosion is a significant global threat to socioeconomic and environmental sustainability, making it widespread natural hazard. Developing spatial models for gully crucial local governance effectively implement mitigation measures promote regional development. This study applied two machine learning (ML) models, RF XGB, alongside an AHP-based multi-criteria decision method FR bivariate statistics, assess susceptibility (GES) in the Kangsabati River basin eastern India's Chotonagpur plateau fringe. A GIS database was created, incorporating recorded incidents 20 conditioning variables, which were evaluated multicollinearity. These variables served as predictive factors assessing presence area. The models' performance using metrics such RMSE, MAE, specificity, sensitivity, accuracy. XGB model outperformed others, achieving accuracy of 90.22%. found that approximately 6.56% catchment highly susceptible erosion, with 12.39% moderately 81.05% not susceptible. had highest ROC value 85.5 during testing, indicating its superiority over (ROC = 81.7), AHP 79.8), 83.8) models. findings highlight model's efficacy potential large-scale GES mapping.

Climate change has caused a more heterogeneous distribution of extreme precipitation, leading to the deterioration drought-flood abrupt alternation (DFAA) events and soil erosion. The security sustainable utilization water resources are severely threatened. Previous studies have focused separately on these two aspects, failing comprehensively consider their interrelationship. Furthermore, often rely climate models with convection parameterization, resulting in substantial uncertainties. We use 4 km convective permitting model (CPM) generate reliable outputs for precipitation. By incorporating long-cycle transition index Revised Universal Soil Loss Equation model, we analyze changes DFAA erosion, as well interconnectedness. results show that CPM outperforms coarse-resolution reproducing erosive rainfall simulating by capturing processes effectively. Projections indicate an escalation occurrence erosion due uneven Specifically, frequency flood-to-drought (FTD) within is projected rise from 3.8 4.7 per decade. loss increase 61 t·hm−2·a−1, 73% area experiencing severe intensity. A positive correlation between FTD found throughout most Guangdong. This will be further amplified events. Consequently, existing conservation measures rendered inadequate, presenting challenges adaptation ecological protection region.

The primary factors controlling regional gully distribution in mountainous areas are poorly understood. To investigate the spatial characteristics and of gullies at scale, kernel density (KD) estimation, semivariogram, Geodetector methods were used based on 11 environmental Yuanmou dry-hot valley. results show that (a) widely but unevenly distributed valley, with an average KD 1.155 km/km 2 , displays autocorrelation over diverse scales; (b) relief amplitude (Ra), landform type, slope distribution, land use precipitation, elevation also important factors; (c) a high risk erosion occurs more than 1437 m, greater 15°, Ra 173 grassland vegetation or luvisols cambisols soil types. These will not only help to understand pattern formation mechanism macroscopic scale provide scientific reference for management.
