Summary: This study presents a straightforward method, Las2DoD, to quantify surface change directly from point clouds. The method was applied to two case studies of erosion and showed higher accuracy in measuring sediment compared to other commonly used methods. Las2DoD is able to capture more low-magnitude changes and is particularly useful in cases where surface changes are small but contribute significantly to the total surface change.

Summary: Road-related soil erosion is a significant issue that can be properly evaluated using terrestrial laser scanning. The study in Southeast China found that soil losses from unpaved roads were closely related to segment length, gradient, and upstream flow area. Predictive models based on gradient and distance were effective in estimating erosion risk along roads.

Summary: Debris flows are rapid movements of highly water-saturated colluvial and proluvial deposits, influenced by factors such as morphometric characteristics and rock composition. This research focuses on analyzing morphometric parameters in Eastern Rhodopes in Bulgaria to distinguish between different types of debris flows and assess their susceptibility to occur. Data such as basin area, relief, slope, and Melton index are calculated to determine key factors in debris flow initiation and type discrimination.

Summary: A four-day glacier-melt flood in August 2013 caused sudden geomorphic changes in the Scott River in SW Svalbard. These floods are becoming more frequent on Svalbard due to abnormally warm or rainy weather in summer or early autumn. The flood was triggered by high precipitation and a rise in temperature, leading to a rapid increase in discharge and mobilization of sediment in the river.

Summary: Since the end of the Little Ice Age, the shrinkage of glaciers in mid-latitude high mountain areas has led to the onset of paraglacial dynamic and made proglacial areas highly sensitive to climate change. The Digital Elevation Model (DoD) technique, which measures volumetric changes in a territory, was used to study the post-LIA deglaciation dynamics of the Martello Valley in the Italian Alps. The analysis showed significant surface effects of paraglacial processes and the transportation of sediments down valley.

Summary: This study analyzed the effects of gully control measures on runoff and sediment transport processes in an agroforestry system in SW Spain. The results showed that the control measures did not affect flood discharge, but reduced suspended sediment concentration by 65%. The implementation of runoff and sediment control measures stabilized the expansion of the channel network and had short-term beneficial effects. Long-term monitoring is needed to understand the long-term effects.

Summary: By studying soil samples from different slope directions along an elevational gradient in a mountain ecosystem, we found that soil bacterial diversity and microbial functions exhibit distinct elevational patterns, which are consistent across slope directions. The bacterial diversity shows a hump-shaped pattern, while microbial functions exhibit a linear increasing trend. Additionally, the beta diversity pattern of soil bacteria is significantly influenced by elevational distance decay relationships. Soil bacterial diversity patterns are determined by transitions in community assembly processes, whereas microbial functions are mainly influenced by bacterial community composition.

Summary: Soil respiration plays a crucial role in the global carbon cycle in arid and semi-arid regions, and is regulated by hydrothermal factors. This study examined the seasonal and diurnal dynamics of soil respiration in two typical ecosystems in northern China, and investigated their responses to precipitation, temperature, and drought. The results showed that soil respiration varied seasonally and diurnally, and its response to environmental factors depended on the ecosystem type and soil moisture status. Incorporating multiple factors into carbon cycle models can improve the simulation and prediction of carbon emissions in arid and semi-arid regions.

Summary: Lake drawdown areas, where sediment is exposed due to water level fluctuations, have a significant impact on the carbon cycle. This study examined microbial necromass carbon (MNC) content and its contribution to soil organic carbon (SOC) in different habitats within the drawdown area of Dongting Lake. The results showed that MNC content varied among habitats and was primarily influenced by carbon and nitrogen availability, plant biomass, clay content, and soil moisture. External factors, such as plant and soil properties, played a more crucial role in the long-term accumulation of MNC. These findings enhance our understanding of MNC stability in drawdown areas.
