Abstract Patterns and rates of landsliding fluvial sediment transfer in mountain catchments are determined by the strength location rain storms earthquakes, sequence which they occur. To explore this notion, landslides caused three tropical cyclones a very large earthquake have been mapped Chenyoulan catchment Taiwan Central Range, where water discharges rock strengths well known. Prior to M W 7·6 Chi‐Chi 1999, storm‐driven landslide were modest. Landslides occurred primarily low within...
Climate controls landscape evolution, but quantitative signatures of climatic drivers have yet to be found in topography on a broad scale. Here we describe how topographic signature typhoon rainfall is recorded the meandering incising mountain rivers western North Pacific. Spatially averaged river sinuosity generated from digital elevation data peaks typhoon-dominated subtropics, where extreme and flood events are common, decreases toward equatorial tropics mid-latitudes, such extremes rare....
Rivers draining the tectonically active island of Taiwan commonly discharge suspended sediment to ocean at hyperpycnal concentrations (>40 kg m −3 ), typically during typhoon‐driven floods. During period 1970–1999, between 99 and 115 Mt yr −1 was discharged from sea. This amount represents 30–42% total ocean. The spatial distribution broadly mirrors pattern discharge, rivers catchments having recent earthquakes weak rocks, such as Choshui Erhjen, up 50–70% their concentrations. Following...
Erosion of particulate organic carbon (POC) occurs at very high rates in mountain river catchments, yet the proportion derived recently from atmospheric CO 2 terrestrial biosphere (POC non‐fossil ) remains poorly constrained. Here we examine transport POC rivers Taiwan and its climatic geomorphic controls. In 11 catchments have combined previous geochemical quantification source (accounting for fossil bedrock), with measurements water discharge (Q w suspended sediment concentration over...
Super Typhoon Nepartak (2016) was used for this case study because it is the most intense typhoon that made landfall in Taiwan past decade. Winds extracted from Climate Forecast System version 2 (CFSV2) and ERA5 datasets merged with a parametric model using two hybrid techniques served as meteorological conditions driving coupled wave-circulation model. The computed significant wave heights were compared observations recorded at three buoys eastern waters of Taiwan. Model performance terms...
Abstract Distributed activity of geomorphic processes with different spatiotemporal scales is hard to monitor in detail conventional methods but might be detected seismometers. From July September 2010, we deployed 14 seismometers evaluate the ability a two‐dimensional array small interstation distances (11 km) continuously mountain catchment (370 km 2 ) Taiwan. Spectral analysis seismic records highlights sources high‐frequency content (>1 Hz), consistent hillslope and river processes....
Hazards from gravity-driven instabilities on hillslope (termed 'landquake' in this study) are an important problem facing us today. Rapid detection of landquake events is crucial for hazard mitigation and emergency response. Based the real-time broadband data Taiwan, we have developed a near monitoring system, which fully automatic process based waveform inversion that yields source information (e.g., location mechanism) identifies by examining fitness different types mechanisms. This system...
Typhoon-induced storm surges are catastrophic disasters in coastal areas worldwide, although typhoon not extremely high Taiwan. However, the rising water level around an estuary could be a block that obstructs flow of away from and indirectly forms overflow middle or lower reaches river if occurrence highest surge (HSS) coincides with astronomical tide (HAT). Therefore, assessing (HST, combination HSS HAT) hazard along coast Taiwan is particularly important to early warning riverine...
