Sinuosity: a found and erased poem

from “Watersheds” (Regehr, Williams, Wichert) in Special Places: The Changing Ecosystems of the Toronto Region. 1999.

A river’s sinuosity is its tendency to move 

back and forth across the floodplain, 

in an S-shaped pattern, over time, leaving behind 

scars of where the river channel once was.

 

Hydrodynamic forces on a rotating planet mean 

a stream will flow in a straight line only 

if some strong physical structures constrain it.   

 

A stream     constrained by linear hard banks       

develops large vertical sinuosities      undercuts 

the banks.          A flat, hardened bottom          will 

enlarge     horizontal sinuosities     reach laterally

erode riparian materials. Constraining both         sides 

and bottom        builds up momentum and kinetic 

energy        manifests       intensified        turbulence 

downstream             Sooner or later the self-organizing 

turbulence of a flowing stream breaks down        

                      any        

                                           straight-line structure.
