back to River width computation

• Model 1 : width ~ catchment_area
• Model 2 : log(width) ~log(catchment_area)
• Model 3 : log(width) ~ log(catchment_area) + uga
• Model 4 : log(width)~ a*log(catchment area) + b*log(shreve index) +c

Other model :

• Elvira model : model 4 with river >2nd order

Log10(Wet width + 1) = 0.22734+ 0.20045 (log10 catchment area) + 0.25939 (log 10 Shreve index)

• Thornton model : W = 4.98 CA0.47
  

• Data extraction :
  • year > 1987 (RHP)
  • Period : april-october
  • complete sampling method
