Short summary
This research presents a unique debris flow dataset over 64 years (1961–2024) at Jiangjia Ravine, Dongchuan, Yunnan, China. The dataset includes detailed measurements of debris-flow kinematic parameters (velocity, depth, discharge), physical-mechanical properties (particle size, yield stress, viscosity), seismic data, and hydrometeorological records (minute-by-minute rainfall, soil moisture, et al.). The dataset is publicly accessible via the National Cryosphere Desert Data Center (NCDC).

After reviewing 2519 literature and media reports, we compiled the first comprehensive global dataset of 555 debris flow barrier dams (DFBDs) from 1800 to 2023. Our dataset meticulously documents 38 attributes of DFBDs, and we have utilized Google Earth for validation. Additionally, we discussed the applicability of landslide dam stability and peak-discharge models to DFBDs. This dataset offers a rich foundation of data for future studies on DFBDs.

Short summary
The damage patterns of the buildings were classified into three types: (I) buried by primary debris flow, (II) inundated by secondary dam-burst flood, and (III) sequentially buried by debris flow and inundated by dam-burst flood. The threshold of the impact pressures in Zones (II) and (III) where vulnerability is equal to 1 is 84 kPa and 116 kPa, respectively. Heavy damage occurs at an impact pressure greater than 50 kPa, while slight damage occurs below 30 kPa.

Short summary
Antecedent effective precipitation (AEP) plays an important role in debris flow formation, but the relationship between AEP and the debris flow occurrence (Pdf) is still not quantified. We used numerical calculation and the Monte Carlo integration method to solve this issue. The relationship between Pdf and AEP can be described by the piecewise function, and debris flow is a small-probability event comparing to rainfall frequency because the maximum Pdf in Jiangjia Gully is only 15.88 %.

Short summary
An integrated approach comprising a field survey, remote sensing, and hydrodynamic modeling was applied to investigate the Rijieco Glacial Lake Outburst Flood (GLOF) in 1991. The flood caused devastating ecological consequences, like sedimentation and the expansion of an inland lake, which has not yet recovered after three decades. The results help understand the ecological impacts of outburst floods on the Tibetan inland lake system and make future flood hazard assessments more robust.

Short summary
We use a numerical model to find that the relationships of AEP-α and AEP-β can be respectively described by the specific function. The I-D threshold curve can regularly move in the I-D coordinate system rather than a conventional threshold curve stay the same regardless of AEP variation. This work is helpful to understand the influence mechanism of AEP on I-D threshold curve and are beneficial to improve the prediction capacity of the I-D threshold.

We implemented both urban water use schemes in a model (Weather Research and Forecasting model) and assessed their cooling effects with different amounts of water in different parts of the city (center, suburbs, and rural areas) for both road sprinkling and urban irrigation by model simulation. Then, we developed an optimization scheme to find out the optimal water use strategies for mitigating high urban temperatures.

Short summary
This paper shows how glacier-related sediment supply changes in response to earthquakes and climate warming at a catchment in the eastern Himalayas using several decades of aerial imagery and high-resolution UAV data. The results highlight the importance of debris-flow-driven extreme sediment delivery on landscape change in High Mountain Asia that have undergone substantial climate warming. This study is helpful for a better understanding of future risk of periglacial debris flows.
