# Roches Beach coastal hazard probabilistic assessment
|
|
|
|
## Workflow
|
|
|
|
#### 1. Open anaconda prompt.
|
|
|
|
Double-click `anaconda-prompt.bat`
|
|
(All further commands should be entered into this prompt)
|
|
|
|
#### 2. Generate ZSA and ZRFC recession tables.
|
|
|
|
The package required to calculate setbacks based on Nielsen et al. (1992) can be found here:
|
|
http://git.wrl.unsw.edu.au:3000/coastal/nielsen
|
|
|
|
```shell
|
|
> cd lidar
|
|
> python generate_recession_tables.py
|
|
```
|
|
|
|
The setback chainages are saved here:
|
|
|
|
lidar/
|
|
├── recession_results_zrfc.csv
|
|
└── recession_results_zsa.csv
|
|
|
|
The profile cross-sections are plotted here:
|
|
|
|
lidar/
|
|
└── png
|
|
├── P1.png
|
|
├── P2.png
|
|
└── ...
|
|
|
|
#### 3. Prepare input files
|
|
|
|
Update values in `adopted-input-values.xlsx`
|
|
Generate `yaml` files:
|
|
|
|
```shell
|
|
> cd ../inputs
|
|
> python get_adopted_input_values.py
|
|
```
|
|
|
|
The `yaml` files are saved here:
|
|
|
|
probabilistic-analysis/
|
|
├── Roches P1.yaml
|
|
├── Roches P2.yaml
|
|
└── ...
|
|
|
|
#### 4. Run probabilistic simulation
|
|
|
|
```shell
|
|
> cd ../probabilistic-analysis
|
|
> python probabilistic_assessment.py
|
|
```
|
|
|
|
Chainage setbacks are saved in csv files, and diagnostics are saved in csv/png files here:
|
|
|
|
probabilistic-analysis/
|
|
└── output_csv
|
|
│ ├── Roches P1 2022 ZRFC.csv
|
|
│ ├── Roches P1 2022 ZSA.csv
|
|
│ ├── Roches P1 2050 ZRFC.csv
|
|
│ └── ...
|
|
└── diagnostics
|
|
├── Roches P1 2022 ZRFC.csv
|
|
├── Roches P1 2022 ZSA.csv
|
|
├── Roches P1 ZRFC scatter.png
|
|
├── Roches P1 ZRFC timeseries.png
|
|
└── ...
|
|
|
|
#### 5. Generate hazard line shapefile
|
|
|
|
```shell
|
|
> cd ../probabilistic-analysis
|
|
> python csv_to_shp.py
|
|
```
|
|
|
|
Shapefile is saved here:
|
|
|
|
probabilistic-analysis/
|
|
└── output_shp
|
|
├── hazard-lines.dbf
|
|
├── hazard-lines.prj
|
|
└── hazard-lines.shp
|
|
|
|
#### 6. Export maps
|
|
|
|
```shell
|
|
> cd ../qgis
|
|
> export.bat
|
|
```
