Which sinuosity ratio would be classified as weak?

A sinuosity ratio is a measure used to describe the complexity of a river's path, with lower values indicating a straighter river and higher values indicating a more winding or meandering path. In this classification, a weak sinuosity suggests that the river follows a relatively straight course, with minimal deviation from a straight line.

A ratio in the range of 1.0 to 1.2 indicates a very low level of meandering, suggesting that the river is close to straight and exhibits weak sinuosity. This condition is characteristic of rivers in environments where they are unable to meander significantly due to geological or hydrological factors.

The other ranges imply varying degrees of meandering. Values from 1.2 to 1.4 indicate a moderate level of pan, and anything above that (1.4 and above) signifies strong meandering characteristics. Therefore, the classification of weak sinuosity fits best with the ratio provided, which corresponds to a nearly straight river path.
