TL;DR: In this paper, the fluvial export of large woody debris (LWD) was monitored in 131 reservoirs throughout Japan and the watershed area was most important in explaining LWDC carbon export, followed by annual precipitation.

TL;DR: In this paper, the authors examined the differences in LW dynamics, including its recruitment, transport, storage, and fragmentation and decay along the spectrum of watershed sizes, and found that a large proportion of LW produced by forest dynamics and hillslope processes was retained because of the narrower valley floors and lower stream power in small watersheds.

TL;DR: The authors analyzed hourly rainfall data for 613 shallow landslides that occurred from 1963 to 2018 in South Korea to obtain rainfall thresholds and investigated the effect of antecedent rainfall conditions on threshold variations.

TL;DR: In this article, the authors examined variations in sediment and LW discharge with respect to precipitation, the presence of dams, land and river use change, and related channel incision and forest expansion on gravel bars and floodplains across Japan.

TL;DR: In this paper, the authors review variations in LW dynamics along a gradient of watershed sizes and present a generalized view of LW processing at the watershed scale, and is relevant to ecosystem management, disaster prevention and the identification of knowledge gaps.
