Why hydro-dynamic co-efficient used to predict impact force decrease with increase in Froude number of debris flow?

28 August 2019 1 5K Report

During my current study I figure out that hydrodynamic co-efficient value decrease with increase in Froude number. The results also matched with the Cui et al 2015 and Faug 2015 reference lines. However, I am intended to explore the insights of the trends. Anyone please illustrate! The results are enclosed with the query for reference.

well it is naturak,increase in Froude number means increase in hydodynamic resistance or in other word uncrease in frictional forces compared to inertial forces...so increase in resstance will reduce impct force from debris on structures in the flow.
