flood-cascade

A model cascade to translate meteorological drivers to flood hazard.

This modelling chain consists of distinct models to be run in sequence. The code is split up into a number of components relating to preparing or running a specific model. Each of these components has its own README file.

---

Components:

metforcings_prep: Scripts to prepare meteorological forcings to run through the MetSIM and FUSE software.

rivernet_prep: Example configuration file for creating a river network in LFP-Tools. Scripts to downsample a river network to lower resolution (e.g. 3arc-seconds to 9arc-seconds)

FUSE-metsim_prep: Scripts to generate domain ancillary files for the MetSIM and FUSE software.

FUSE_regionalization: Scripts to process datasets for parameter regionalization Code to determine similarity of characteristics between model grid-cells and GRDC catchments

MizuRoute_prep: Scripts to generate mizuroute ancillary files Creates river network file based on output of rivernet_prep code Creates grid mapping file based on output of rivernet_prep and FUSE model grid

LISFLOOD-FP_prep: Example scripts to generate a LISFLOOD-FP model using LFP-Tools Script to determine location of lisflood discharge inputs from river network TODO: Add code for calculating bankfull discharge

submit_scripts Code to be run on a cluster environment to prepare and submit simulations for each of the model components:

1. fuse_catchments
2. fuse_gridded
3. mizuRoute
4. lisflood-fp
