Preliminary Investigations on the Fate of Terrestrial Sediments in the Coastal Ocean Discharged From Taiwanese Small Mountainous Rivers

Oceanic loading of wildfire-derived organic compounds from a small mountainous river

[1] Small mountainous rivers (SMRs) export substantial amounts of sediment into the world’s oceans. The concomitant yield of organic carbon (OC) associated with this class of rivers has also been shown to be significant and compositionally unique. We report here excessively high loadings of polycyclic aromatic hydrocarbons (PAHs), lignin, and levoglucosan, discharged from the Santa Clara River ...

Geomorphic/Tectonic Control of Sediment Discharge to the Ocean: The Importance of Small Mountainous Rivers1

Analysis of data from 280 rivers discharging to the ocean indicates that sediment loadslyields are a log-linear function of basin area and maximum elevation of the river basin. Other factors controlling sediment discharge (e.g., climate, runoff) appear to have secondary importance. A notable exception is the influence of human activity, climate, and geology on the rivers draining southern Asia ...

Flux and fate of small mountainous rivers derived sediments into the Taiwan Strait

Geomorphic Analysis in Determining Coastal Cells and Its Role in Coastal Management (Case Study: Bandar Anzali to Chalous Coasts)

Introduction Due to the different geomorphological and morph dynamic forces of the coastal area, they form different areas. Each of these areas requires its own coastal management. While in our country, coastal management is done without considering the characteristics and coastal characteristics of each coast. In this study, in order to classify coasts and determine coastal cells, morph dynam...

Carbon isotope biogeochemistry of tropical small mountainous river, estuarine, and coastal systems of Puerto Rico

Recent studies have shown that small mountainous rivers (SMRs) may act as sources of aged and/or refractory carbon (C) to the coastal ocean, which may increase organic C burial at sea and subsidize coastal food webs and heterotrophy. However, the characteristics and spatial and temporal variability of C and organic matter (OM) exported from tropical SMR systems remain poorly constrained. To add...
