Abstract Reservoir sedimentation data and sediment yields from Taiwanese rivers show increased soil erosion in response to both 20th century changes in land use and a more recent increase in typhoon frequency and intensity. Decadal variations of up to 5- to 20-fold in suspended-sediment rating curves demonstrate supply-limited transport and correspond to increased sediment delivery from hillslopes due to changes in land use, regional ground shaking during the Chi-Chi earthquake, and post-2000… Expand
An assessment of tropical cyclones rainfall erosivity for Taiwan
TLDR
It is established that typhoons’ mean rainfall erosivity is higher than the global mean rainfallErosivity, and regional variability of typhoons rainfall erOSivity showed an increasing pattern from north to south, with relatively higher values over eastern and southern parts of Taiwan. Expand

TLDR
The results from this in-situ study suggest that recovering landslide scars are strong carbon sinks once an initial lag period of vegetation re-establishment is overcome. Expand
