1D breach tool to model three types of breach

HR Breach v4.3

HR BREACH encapsulates a one-dimensional flow model which accounts for a constant degree of flow contraction, and a simple geotechnical failure model to simulate breach in the case of homogeneous embankments, with or without a homogeneous core of a different material.

Since floods can result in large number of fatalities and/or substantial economic losses, accurate flood spreading predictions are necessary to design appropriate action plans and to reduce and manage flood risk. For this reason HR Breach was integrated into the well proven InfoWorks‑RS model which has one‑dimensional and two-dimensional flood modelling capabilities.
