This document contains the requirements and functional design for a software kernel that computes the safety assessments of Liquefaction and Breach flowassessment of the failure mode flow slide.
Requirements
The functional requirements for D-FlowSlide are:
...
- A Global check according to the global assessment rules given in Toetsproces zettingsvloeiing; A Toetsmethode zettingsvloeiing (versie 2, 22 februari 2016) ; A Global assessment is solely based on geometric characteristics of under water slope and levee,
- A Detailed check according to the probabilistic assessment method described in Toetsproces zettingsvloeiing; With the Toetsmethode zettingsvloeiing (versie 2, 22 februari 2016); In the detailed check also soil properties are taken into account.
- An Advanced check, using two is usingthe two advanced programs of Deltares:
- Advanced check for static liquefaction, using the original program Sliq2D
- Advanced check for breach flow, using the original program HMBreach.
