MRBreach is written in Matlab(TM) and requires v2016b, or later. In addition, MRBreach requires both the dstoolbox and the muitoolbox.
MRBreach is a utility to support the design of the sort of breach in a sea wall that is commonly required for managed realignment schemes. These schemes aim to increase the area of intertidal by allowing the sea back into areas of land that have been protected by sea defences in the past. It is usually impractical to remove the entire sea wall. There is therefore a need to determine the size of breach required to allow tidal exchange into and out of the site. In such design there is also the practical consideration of being able to construct the breach safely, in the time available over a tidal cycle. This piece of software implements a method proposed for the design of such breaches based on creating one, or more, stable channels into the site.
- MRBreach - defines the behaviour of the main UI.
- mrSiteData - handles input of site parameters.
- mrBreachData - handles input of hydraulic parameters.
- mrHypsometry - handles import of measured hypsometry from file and computation of empirical 'fitted' hypsometry.
- mrBreachModel - computes breach regime section
The MRBreach manual in the app/doc folder provides further details of setup and configuration of the model. The files for the example use case can be found in the app/example folder.
