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.
In the folowing paragraphs the functional design for D-Flow Slide has been explained. Detailed documentes can be found in the literature list
The definition of the symbols used in this Background section can be found in the Symbols list.
