This document contains the requirements and functional design for a software kernel that computes the safety assessments of Liquefaction and Breach flow.
Requirements
The functional requirements for D-FlowSlide are:
- Every computation by D-Flow Slide deals with one surface level and a 1D Soil profile.
- The safety assessment consists of passing through different phases:
- A Global check according to the global assessment rules given in Toetsproces zettingsvloeiing; 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 detailed check also soil properties are taken into account.
- An Advanced check, using two advanced programs of Deltares:
- Advanced check for static liquefaction, using the program Sliq2D
- Advanced check for breach flow, using the program HMBreach.
The definition of the symbols used in this Background section can be found in the Symbols list.
