The impact of land use change on soil infiltration capacity and whether the runoff generation mechanisms in typical watersheds of the Loess Plateau might change under strongly varying surface conditions remain unclear. This study selected three land use types in the Loess Plateau: forestlands, grasslands, and wastelands. Using a double-ring infiltrometer and artificial rainfall simulation, infiltration tests and rainfall-runoff experiments were conducted under different land use types to investigate the effects on soil properties, infiltration capacity, and slope runoff mechanisms. The results indicated that land use change significantly reduced the bulk density of shallow soils. Forestlands and grasslands exhibited significantly higher mean weight diameter and saturated hydraulic conductivity. Land use change effectively improved the infiltration characteristics. The infiltration characteristics of the soil vary across different soil layers. In the 0–30 cm soil layer, <em>K</em>s (saturated hydraulic conductivity) made a significant contribution to soil infiltration performance. In the simulated rainfall experiments, subsurface flow was observed in both forestlands and grasslands. Due to land use change, the soil infiltration capacity was significantly enhanced, which in turn affected the transformation of runoff generation mechanisms. This suggests that changes in soil infiltration due to land use change lead to a shift in slope runoff generation mechanisms, potentially transitioning from a single surface infiltration excess overland flow mechanism to a combination of infiltration excess overland flow and subsurface flow mechanisms. These findings enhance the understanding of hydrological processes such as infiltration and runoff after land use change.</div></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":"261 ","pages":"Article 109517"},"PeriodicalIF":5.7,"publicationDate":"2025-10-04","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145219247","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, it remains poorly studied when it comes to long-term sediment dynamics. This study presents the first comprehensive assessment of 45 years (1973–2018) of suspended sediment trends across the Cauvery basin, combining non-parametric methods (Mann-Kendall test, Pettitt test, double-mass curves), disentangling drivers of trends and assessing downstream impacts. Results indicate alarming consistent sediment reductions at 13 of 14 stations, with 12 showing statistical significance (p &lt; 0.05) over the past two decades. The sharpest decline occurred in the middle reach (Biligundulu: 33.79 × 10<sup>3</sup> t yr<sup>−1</sup>), followed by the terminal station Musiri (13.73 × 10<sup>3</sup> t yr<sup>−1</sup>). From 2000 to 2018, the average sediment load at Musiri decreased by 68 %, while upstream tributaries Hemavati and Shimsha showed 71 % and 76 % decline, respectively. These declines exceeded those reported in larger rivers such as the Godavari or Krishna. Importantly, long-term rainfall showed no significant trends, ruling out climate as a primary driver. Change-point analysis identified abrupt sediment reductions during the mid-1990s to early 2000s, coinciding with NDVI-linked vegetation health recovery post-1990 and dam construction peaks. Land-use shifts (1985–2005) led to a decrease in forest and agricultural areas by 8 % and 3.5 %, respectively, while built-up areas expanded by 140 %, likely leading to an initial increase in sediment load. Sediment starvation caused severe coastal erosion in the Cauvery delta, with over 300 m of retreat at the estuary and localised recession exceeding 500 m. Previously stable lagoons are now experiencing intensified erosion and reflecting deltaic vulnerability.

Mapping of environmental vulnerability to linear erosive processes was carried out in 1985 and 2022, based on the Analytic Hierarchy Process (AHP), fieldwork, and soil collection at three points, enabling identification of three levels of environmental vulnerability: low, medium, and high. Areas with low environmental vulnerability presented the smallest percentage area (15.10% in 1985 and 12.85% in 2022) and was related to flat tops of hills, remaining Cerrado vegetation of forest and savanna formations, and sandy soils. The medium environmental vulnerability showed an increase in area of ​​7.18% in the period analyzed and the main cause for this was deforestation for pasture and soybean plantations. The high environmental vulnerability was significant, with 47.09% and 42.16% of the total area in 1985 and 2022, respectively, and including areas of steep slopes, clayey and shallow soils, pasture, and exposed soil. Given these results, it is concluded that the various phytophysiognomies of the Cerrado are being deforested by anthropogenic activities, which are the main factor in accelerated erosion.

This study addresses the existing gap in comprehensive comparisons of sediment connectivity indices by evaluating two widely used methods: the structural-based Borselli index (IC_B) and the process-based InVEST-SDR model (IC_InVEST). Both models were applied to the Taleghan watershed in Iran, utilizing a digital elevation model (DEM) combined with spatial datasets, including land cover, soil type, and rainfall erosivity. The evaluation employed statistical tools such as correlation analysis, Wilcoxon signed-rank test, linear regression, and root mean square error (RMSE) to quantify model performance against field-based sediment connectivity (FIC) data. Results indicate that IC_InVEST achieved a higher correlation (r = 0.88) with FIC and explained 77 % of sediment variation, outperforming IC_B which explained 62 %. However, limitations in field data necessitate cautious interpretation. This research highlights the importance of integrating both topographic and process-based factors in sediment connectivity assessment and underscores the need for standardized methodologies and extensive field validation. Furthermore, a regression-based adjustment was proposed to enhance comparability between indices. The findings suggest that model selection should be guided by data availability, watershed characteristics, and specific management objectives. InVEST-SDR’s relatively low data requirements make it practical for identifying erosion-prone hotspots, facilitating proactive watershed protection.

Here, we examine this mechanism using 330 recorded landslides from February to April 2022 across the North Anatolian Mountains (Türkiye). Our results demonstrate that ARs significantly contributed to snowmelt (up to 250 mm per event), stimulated by abrupt temperature increases (up to +6 °C) and rain-on-snow conditions, with rainfall and snowfall reaching up to 100 mm and 40 mm, respectively; all differences were statistically significant (p &lt; 0.01) when comparing AR and non-AR days.

The results highlight the compound effect of ARs on landslide initiation and suggest that warming-driven snowmelt can substantially contribute to slope destabilization. This study provides a framework for understanding AR-related landslide hazards in other midlatitude mountain regions, including the Pacific Rim, the Andes, High Mountain Asia, and the Alps.

In this study, we have measured D<sub>r</sub> and FSD in rills with length of 0.75, 1.5, and 2.5 m, using an experimental flume (3.5-m long) and soil samples collected in a burned and deforested site in Northern Iran. Soil slope and flow discharge were from 5.4 to 21.2 %, and from 0.55 to 0.94 L m<sup>−1</sup> s<sup>−1</sup>, respectively. The highest D<sub>r</sub> (on average 0.072 kg m<sup>−2</sup> s<sup>−1</sup>) was measured at the upstream side of the rill (being equal to the maximum rate). Downstream of the rill, this rate was lower (by −64 % for a rill length of 0.75 m to −9.5 % for 2.5 m) and the minimum value (0.026 kg m<sup>−2</sup> s<sup>−1</sup>) was measured for the shortest rill (0.75 m). D<sub>r</sub> monotonically increased with slope and flow discharge for a given rill length. The variability rate of D<sub>r</sub> can be estimated with very high precision by power equations, adopting the shear stress (Nash and Sutcliffe’s coefficient of efficiency, NSE, over 0.94) and stream power (NSE &gt; 0.89) as input variables. Despite our study being limited by the small scale and the local soils, the results quantify the variability of D<sub>r</sub> and flow sediment deficit along a rill in the experimental field conditions. The proposed equations are useful to predict these variables depending on rill length in physically-based erosion models in areas with climatic and geomorphological characteristics similar to the experimental sites.</div></div>","PeriodicalId":9801,"journal":{"name":"Catena","volume":"260 ","pages":"Article 109481"},"PeriodicalIF":5.7,"publicationDate":"2025-09-30","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145217433","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
