Here we calibrate satellite imagery to estimate suspended sediment concentration for 160 proglacial rivers across Greenland.
This work is unique in predicting minimum sediment concentration.
Holdaway, G. P., Thorne, P. D., Flatt, D., Jones, S. E. & Prandle, D. Comparison between ADCP and transmissometer measurements of suspended sediment concentration.
To investigate whether a more detailed consideration of spatial variations in sediment concentration could affect our results, we developed a spatially variable sediment concentration model based on measurements in our site46, which includes three mangrove sites and six saltmarsh sites (Table 1).
Regression and BPNN model are then coupled with GA to acquire sediment concentration.
For minimum sediment concentration, optimum discharge and temperature were obtained from coupled GA.
BPNN and Regression models had been used to map the sediment concentration with discharge and temperature.
Water discharge and suspended sediment concentration have also decreased with time.
Walleye embryo survival differed between the tailings pond sediments, and survival decreased with increasing sediment concentration.
Over short timescales, rainstorm events caused the changes of suspended sediment concentration (SSC) in the rivers.
The regressive equations can explain the major driving forces behind the suspended sediment concentration dynamics.
