The resulting equations were verified and validated by applying them to generate cross-sections for eight Storm Water Management Models. Results showed a correlation between drainage area and channel morphology, attributed to the presence of areal/shape characteristics in all the specific-region equations. Verification with an independent watershed sample demonstrated the predictive equations’ robustness and reliability. The study found that subdividing homogeneous regions improved accuracy compared to previous studies.

While current approaches have been successful for dry climates, their requirement to filter out rainfall-affected data often leads to inaccurate estimates for flow components in wet and semi-wet climates or seasons.
