Summary: The study investigates the impact of climate change on the hydrology of the Yarlung Zangbo River, analyzing different runoff components and their responses to climate change. Results suggest that total runoff may decrease at some stations while increase at others, with potential shifts in the dominant runoff sources in the future due to changing climate patterns.

Summary: This study investigates a multi-channel confluence between the Yarlung Zangbo River and its major tributary, the Niyang River. The study finds that the confluence is stable compared to its upstream and downstream reaches. The separation of the Niyang River inflows by a delta creates a mixing interface and secondary cells in the Yarlung Zangbo River. The curved riverbank plays a significant role in the formation of deep scour holes and heterogeneity of velocity distribution.

Summary: This study established a hydrological model in the Yarlung Zangbo River Basin to evaluate the impacts of climate change on water resources and future water supply. The results showed that despite the decrease in glacier meltwater and snow runoff, the increase in precipitation is expected to result in an overall increase in runoff in the basin. It is projected that water resources in the Yarlung Zangbo River Basin will increase in the coming decades.

Summary: Two different methods were proposed to obtain higher precision regional precipitation dataset in the Yarlung Zangbo River basin using IMERG and CMORPH_BLD satellite-based precipitation products. These methods resulted in better performance in various evaluation metrics and streamflow simulation compared to the original IMERG dataset. The methods are relatively simple and efficient, and demonstrated good applicability in the alpine region.

Summary: Aeolian sediment emission and transport are significant geological processes, and the Yarlung Zangbo River basin in the Tibet Plateau experiences strong aeolian activity. However, research on this activity is limited, resulting in a lack of knowledge to support mitigation or prevention efforts for aeolian disasters. Through measurements in the Yarlung Zangbo River, we found spatial and temporal variations in sediment transport rates, with the highest rates in spring and winter. River banks and floodplains were identified as major dust sources due to rich deposits of fine sand, silt, and clay.

Summary: Microorganisms play a critical role in nitrogen removal in high-altitude rivers, which is influenced by various environmental factors and human activities. This study investigated nitrogen conversion rates and bacterial communities in the Yarlung Zangbo River and found that denitrification was the dominant process for nitrate removal. Environmental factors and denitrifier abundance jointly regulated nitrogen removal in high-altitude rivers.

Summary: This study examines hydro-climatic changes in the Yarlung Zangbo River Basin in Tibet since the Last Glacial Maximum by combining proxy records with climate simulations and glacier reconstructions. The results show that runoff was low during the Last Glacial Maximum and Heinrich Stadial 1, due to less precipitation contribution and larger glacier coverage. Rapid deglaciation and increasing runoff between Heinrich Stadial 1 and the Bolling-Allerod interval may have led to extreme outburst flood events.

Summary: This study aimed to evaluate land surface phosphorus losses and fluvial phosphorus fluxes in a highland river basin. The results showed that phosphorus loss intensity and fluvial phosphorus flux were higher on the south bank compared to the north bank, and the phosphorus transport flux in the Shigatse basin was lower compared to other large rivers in the world. The study also examined the impact of meteorological conditions, underlying surface conditions, and fluvial phosphorus retention on phosphorus fluxes.

Summary: Topography plays a key role in shaping erosion and deposition patterns of different landscapes. This study focused on investigating the influence of various microtopographic factors on rill erosion and deposition on a hillslope. The results demonstrate that the contributing area is the most important factor, while factors such as slope, roughness, aspect, and terrain wetness index also play a role in sediment dynamics.

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: Reconstructing palaeoglaciers is important for assessing the impact of glacier change on water resources and studying palaeo-climate conditions. This paper introduces an automated method called PalaeoIce, which uses geomorphic constraints to reconstruct palaeoglaciers. The method is implemented using a Python-coded ArcGIS toolbox and includes tools for generating glacial flowlines, optimizing shear stress, deriving shape factors, calculating ice thickness values, and interpolating palaeo ice surfaces.

Summary: The accuracy and quality of landslide susceptibility mapping can be improved by using the proposed objective method based on Mahalanobis distances (MD) to determine the critical value for sampling absence data. In this study, the method was applied to three subdistricts in Rangamati district, Bangladesh and compared with a slope-based sampling method. The results showed that the proposed method produced a landslide susceptibility map with higher model fitting, prediction, and Kappa values compared to the slope-based sampling method. Therefore, it is recommended to use MD-based absence data sampling for landslide susceptibility mapping.

Summary: Rehabilitation of hearing perception in Mandarin-speaking cochlear implant patients was analyzed. A linear relationship between aided hearing threshold and speech perception accuracy was found. Individual differences in speech perception accuracy were observed, with some patients scoring lower than expected. The timing of cochlear implantation and rehabilitation training significantly impacted speech perception accuracy, with improvements seen over time. Delayed auditory deprivation resulted in poorer speech perception accuracy. Early cochlear implantation and post-operative rehabilitation are important for recovery of speech perception accuracy in cochlear implant patients.

Summary: In recent decades, glaciers have been melting, thinning, and retreating globally due to increasing temperatures. Using a glacial flowline model, the study simulated the ice thicknesses and volumes in the Southern Tibetan Plateau. The results showed that glaciers on the western slopes of Mt Noijin Kang-Sang retreated more extensively compared to those on the eastern slopes, likely due to their smaller size and lower elevations.
