  • Suspended sediment load transport in the Mississippi River basin at St. Louis : temporal scaling and nonlinear determinism
  • Carrying capacity ; Correlation ; Determinism ; Mississippi ; Missouri ; Model ; Statistics ; Stream ; Suspended load ; United States of America
  • This study investigates the dynamic behaviour of suspended sediment load transport at different temporal scales in the Mississippi River basin. Data corresponding to 5 successively doubled temporal scales (i.e. daily, two-day, four day, eight day
  • , and 16-day) from the St. Louis gauging station in Missouri are analyzed. The investigation is focused on identifying possible low-dimensional deterministic behavior in the suspended sediment load transport dynamics, with an aim towards reduction in model

  • Suspended sediment flux modeling with artificial neural network : an example of the Longchuanjiang River in the Upper Yangtze catchment, China
  • China ; Comparative study ; Model ; Multiple regression ; Neural network ; Precipitation ; Stream ; Suspended load ; Temperature ; Yunnan
  • In this study, the AA. applied artificial neural network (ANN) to simulate monthly suspended sediment flux from 1960 to 2001 in the Longchuanjiang River. The ANN constructed from climatic variables only (rainfall, temperature) will have a potential
  • of filling missing data in a suspended sediment flux time series and predicting the influence of climatic change on suspended sediment flux. The advantage of ANN were also evaluated by comparing its performance with that of multiple linear regression (MLR

  • Suspended sediment transport in glacial meltwater during the initial quiescent phase after a major surge event at Kuannersuit Glacier, Greenland
  • Cold area ; Glacier ; Greenland ; Ice breakup ; Meltwater ; Sediment transport ; Suspended load
  • This paper describes a rough estimate of the suspended sediment transport in the bulk meltwater evacuated from Kuannersuit Glacier during the summers of 2000 and 2001, where the drainage system is probably still developing after a major surge event

  • The focus in this paper is on the lower reaches of the Waipaoa River, New Zealand, and their response to a massive increase in suspended-sediment load (and only a small, concurrent increase in water discharge) following deforestation. The AA. use
