Comparisons are made between these ecological approaches and estimates of geochemical fluxes based on sediment trapping, one-dimensional geochemical models and horizontal (physical) input from continental margins.
Determination was based on sediment contaminant indicators (SCIs), including interstitial salinity, hydrocarbons, metals, and radium concentrations.
Based on sediment composition and texture, and faunal content, core sediments were divided into six depositional units.
We improved the Location-weighted landscape Contrast Index which was developed based on sediment source sink theory.
The publications reviewed are based on sediment sequences which provide C14-dated pollen records, charcoal and geochemical data.
The wave reflection coefficient is determined from parameters based on sediment layer thickness, its material properties and excitation frequencies.
That's the conclusion of a report published Wednesday in the journal Science Advances, based on sediment cores from a small lake in the central plateau of Grande Terre.
The four landscape metrics selected for the study were based on sediment travel time, sediment transport capacity, flux connectivity, and residence time.
However, we find no studies develop a watershed erosion modeling framework based on sediment connectivity, and few, if any, studies have quantified sediment connectivity for gently rolling systems.
Empirical models that are based on sediment flux controls such as sediment supply, transport capacity, and gradient serve to explain differential floodplain construction.
