“…4a), which to some extent complicates the interpretation of a warm-wet relationship between the TP surface temperature and the EGS moisture change in its southeastern region. However, two moisture-sensitive chronologies used in the study contain very weak or no prior winter temperature signal (Fan et al 2008a;Liu et al 2012) and that exhibit coherent variations with our chronology (Fig. 6), proving that the warm-wet relationship is not due to the inclusion of winter temperature signal in our chronology.…”

“…To examine whether it represents large-scale moisture change back in time, we compared our reconstruction with three tree-ring records (BM, LX, and LZ, Fig. 1) that are also most sensitive to the EGS moisture condition on the southeastern TP (Fan et al 2008a;He et al 2012;Liu et al 2012). As shown in Fig.…”

“…Here we use tree-rings to study common moisture change on the southeastern TP during the past five centuries, and examine whether regional moisture change is related to large-scale TP surface temperature anomaly from a long-term perspective. Tree-rings are employed as a proxy in light of their precise dating, annual resolution, and high sensitivity to climate change in the study area (Fan et al 2008a;Fang et al 2010;Liu et al 2012;Duan and Zhang 2014).…”

Rapid warming has been observed in the high-altitude areas around the globe, but the implications on moisture change are not fully understood. Here we use tree-rings to reveal common moisture change on the southeastern Tibetan Plateau (TP) during the past five centuries, and show that regional moisture change in late spring to early summer (April-June) is closely related to large-scale temperature anomaly over the TP, with increased moisture coincident with periods of high temperature. The most recent pluvial during the 1990s-2000s is likely the wettest for the past five centuries, which coincides with the warmest period on the TP during the past millennium. Dynamic analysis reveals that vertical air convection is enhanced in response to anomalous TP surface warming, leading to an increase in lower-tropospheric humidity and effective precipitation over the southeastern TP. The coherent warm-wet relationship identified in both tree-rings and dynamic analysis implies a generally wetter condition on the southeastern TP under future warming.

Case Study: Effects of a Partial-Debris Dam on Riverbank Erosion in the Parlung Tsangpo River, China

This paper examines two successive debris flows that deposited a total of 1.4 million m 3 of sediment into the Parlung Tsangpo River in China in 2010. As a result of these deposits, a partial-debris dam was formed in the river. This dam rerouted the discharge in the river along one of the riverbanks, which supported a highway. The rerouted discharge eroded the riverbank and the highway eventually collapsed. To enhance our understanding of the threat posed by partial-debris dams, a field investigation was carried out to measure the discharge in the river and to collect soil samples of the collapsed riverbank. Findings from the field investigation were then used to back-analyze fluvial erosion along the riverbank using a combined erosion framework proposed in this study. This combined framework adopts a dam-breach erosion model which can capture the progressive nature of fluvial erosion by considering the particle size distribution of the soil being eroded. The results from the back-analysis were then evaluated against unique high-resolution images obtained from satellites. This case study not only highlights the consequences of the formation of partial-debris dams on nearby infrastructure, but it also proposes the use of a combined erosion framework to provide a first-order assessment of riverbank stability. Unique high-resolution satellite images are used to assess the proposed erosion framework and key challenges in assessing erosion are discussed.
