Chris Leaman d06a5ab576 Removes TWL forecast using foreshore slope from Makefile
Predicting TWL using time-varying foreshore slope is pretty slow, so let's remove it from our data analysis pipeline. The code is still there if we want to call it, but for the time being, let's remove this model when we're looking at comparisons.

Chris Leaman a293d5d691 Fix incorrect calculation of pre/post change point
If pre and post storm profiles returned to similar elevations within the sampled profile length, the change point detection would select the most seaward point and incorrectly calculate the swash zone volumes. This change looks at the slope of the difference between the two profiles and assumes that the difference between the two profiles should be increasing at the location of the change point.

Chris Leaman 7069c3b627 Extract slope & width change for observed impacts 6 years ago
Chris Leaman 217e633ffc Extract function for getting slopes
This is so it can be called from observed_storm_impacts.py. It might be better to put these in a slope_utils.py function?

Chris Leaman 557c15df1f Enable observed impacts to be overwritten with NaN
This is useful where we have a structure or rock wall and want to specify that we don't know what the observed storm regime is. In this case, we'll put a 'unknown' string in the ./data/raw/profile_features observed storm impact csv field and overwrite it with a NaN in our pandas dataframe.

Chris Leaman 1774c15e89 Fix finding z elevation of dune toe/crests
If the x-coordinate specified for the toe/crest does not exist for the profile type, this fixes an issue where the z-elevation of the other profile type was not being correctly calculated. Also, some commented out code is removed.

Chris Leaman cdca489e4a Fix dune toe TWL exceedence hours
Dune toe TWL exceedence hours were being left as zero if the profile didn't have a dune toe (technically correct). In these cases it's more useful to calculate the exceedence hours of the dune crest level.

Chris Leaman 1fca122276 Ensure float precision is limited when outputting csv
Without this change, interim .csv files were being recorded with 9 decimal places, greatly increasing the file size. This keeps the number of decimals limited to a practical amount.

Chris Leaman bf61116efb Remove R_low requirement when forecasting overwash
Some runup parameterizations only give R_high, but not R_low. In these cases, let's just classify the profile as overwash if R_high > D_high.

# 2016 Narrabeen Storm EWS Performance
This repository investigates whether the storm impacts (i.e. Sallenger, 2000) of the June 2016 Narrabeen Storm could
have been forecasted in advance.
This repository investigates whether the storm impacts ([Sallenger, 2000](https://www.jstor.org/stable/4300099#metadata_info_tab_contents)) of the June 2016 Narrabeen Storm could have been forecasted in advance. At 100 m intervals along each beach, we hindcast the storm impact as one of the four regimes defined by Sallenger (2000): swash, collision, overwash or inundation.

## Repository and analysis format
This repository follows the [Cookiecutter Data Science](https://drivendata.github.io/cookiecutter-data-science/)
structure where possible. The analysis is done in python (look at the `/src/` folder) with some interactive,
exploratory notebooks located at `/notebooks`.
Development is conducted using a [gitflow](https://www.atlassian
.com/git/tutorials/comparing-workflows/gitflow-workflow) approach - mainly the `master` branch stores the official
release history and the `develop` branch serves as an integration branch for features. Other `hotfix` and `feature`
branches should be created and merged as necessary.
## Where to start?
1. Clone this repository.
2. Pull data from WRL coastal J drive with `make pull-data`
3. Check out jupyter notebook `./notebooks/01_exploration.ipynb` which has an example of how to import the data and
some interactive widgets.

Other `hotfix` and `feature` branches should be created and merged as necessary.
## How to start?
#### Getting software requirements
The following requirements are needed to run various bits:
- [Python 3.6+](https://conda.io/docs/user-guide/install/windows.html): Used for processing and analysing data.
Jupyter notebooks are used for exploratory analyis and communication.
- [QGIS](https://www.qgis.org/en/site/forusers/download): Used for looking at raw LIDAR pre/post storm surveys and
extracting dune crests/toes
- [rclone](https://rclone.org/downloads/): Data is not tracked by this repository, but is backed up to a remote
Chris Leaman working directory located on the WRL coastal drive. Rclone is used to sync local and remote copies.
Ensure rclone.exe is located on your `PATH` environment.
- [gnuMake](http://gnuwin32.sourceforge.net/packages/make.htm): A list of commands for processing data is provided in
the `./Makefile`. Use gnuMake to launch these commands. Ensure make.exe is located on your `PATH` environment.
- [Anaconda](https://www.anaconda.com/download/): Used for processing and analysing data. The Anaconda distribution is used for managing environments and is available for Windows, Mac and Linux. Jupyter notebooks are used for exploratory analyis and communication.
- [QGIS](https://www.qgis.org/en/site/forusers/download): Used for looking at raw LIDAR pre/post storm surveys and extracting dune crests/toes
- [rclone](https://rclone.org/downloads/): Data is not tracked by this repository, but is backed up to a remote Chris Leaman working directory located on the WRL coastal drive. Rclone is used to sync local and remote copies. Ensure rclone.exe is located on your `PATH` environment.
- [gnuMake](http://gnuwin32.sourceforge.net/packages/make.htm): A list of commands for processing data is provided in the `./Makefile`. Use gnuMake to launch these commands. Ensure make.exe is located on your `PATH` environment.
- [git](https://git-scm.com/book/en/v2/Getting-Started-Installing-Git): You'll need to have git installed to push and pull from this repo. If you're not familiar with the command line usage of git, [Git Extensions](http://gitextensions.github.io/) is a Windows based GUI which makes it easier to work with git. There are a whole bunch of other [git clients](https://github.com/dictcp/awesome-git#client) that are available as well.
#### Getting the repository
Clone the repository onto into your local environment:
```sh
git clone http://git.wrl.unsw.edu.au:3000/chrisl/nsw-2016-storm-impact.git
cd nsw-2016-storm-impact
```
#### Getting the python environment set up
Commands for setting up the python environment are provided in the `Makefile`. Simply run the following commands in the repo root directory, ensuring `make` is located on your path:
```sh
make venv-init
make venv-activate
make venv-requirements-install
```
You can see what these commands are actually running by inspecting the `Makefile`.
#### Pull data
The actual raw, interim and processed data are not tracked by the repository as part of good git practices. A copy of the raw data is stored on the WRL Coastal J:\ drive and can be copied using the following command.
```sh
make pull-data
```
If you have updated the data and want to copy it back to the J:\ drive, use the following command. Note that it is probably not a good idea to modify data stored in `./data/raw/`.
```sh
make push-data
```
#### View notebooks
Jupyter notebooks have been set up to help explore the data and do preliminary analysis. Once you have set up your environment and pulled the data, this is probably a good place to start. To run the notebook, use the following command and navigate to the `./notebooks/` folder once the jupyter interface opens in your web browser.
```sh
make notebook
```
In order to allow notebook to be version controlled, [nbstripout](https://github.com/kynan/nbstripout) has been installed as a git filter. It will run automatically when commiting any changes to the notebook and strip out the outputs.
## Available data
Raw, interim and processed data used in this analysis is kept in the `/data/` folder. Data is not tracked in the
repository due to size constraints, but stored locally. A mirror is kept of the coastal folder J drive which you can
use to push/pull to, using rclone. In order to get the data, run `make pull-data`.

List of data:
- `/data/raw/processed_shorelines`: This data was recieved from Tom Beuzen in October 2018. It consists of pre/post
storm profiles at every 100 m sections along beaches ranging from Dee Why to Nambucca . Profiles are based on raw
aerial LIDAR and were processed by Mitch Harley. Tides and waves (10 m contour and reverse shoaled deepwater) for
each individual 100 m section is also provided.
- `/data/raw/raw_lidar`: This is the raw pre/post storm aerial LIDAR which was taken for the June 2016 storm. `.las`
files are the raw files which have been processed into `.tiff` files using `PDAL`. Note that these files have not
been corrected for systematic errors, so actual elevations should be taken from the `processed_shorelines` folder.
Obtained November 2018 from Mitch Harley from the black external HDD labeled "UNSW LIDAR".
- `/data/raw/profile_features`: Dune toe and crest locations based on prestorm LIDAR. Refer to `/notebooks/qgis.qgz`
as this shows how they were manually extracted. Note that the shapefiles only show the location (lat/lon) of the dune
crest and toe. For actual elevations, these locations need to related to the processed shorelines.
- `./data/raw/grain_size/`: The `sites_grain_size.csv` file contains the D50 grain size of each beach as well as the references for where these values were taken from. Grain size is needed to estimate wave runup using the Power et al. (2018) runup model.
- `./data/raw/land_lims/`: Not used (?) CKL to check
- `./data/raw/near_maps/`: This folder contains aerial imagery of some of the beaches taken from Nearmaps. It can be loaded into QGIS and examined to determine storm impacts by comparing pre and post storm images.
- `./data/raw/processed_shorelines/`: This data was recieved from Tom Beuzen in October 2018. It consists of pre/poststorm profiles at every 100 m sections along beaches ranging from Dee Why to Nambucca . Profiles are based on raw aerial LIDAR and were processed by Mitch Harley. Tides and waves (10 m contour and reverse shoaled deepwater) for each individual 100 m section is also provided.

Note that the shapefiles only show the location (lat/lon) of the dune crest and toe. For actual elevations, these locations need to related to the processed shorelines.
- `./data/raw/profile_features_chris_leaman/`: An excel file containing manually selected dune toes, crests, berms and impacts by Chris Leaman. The values in this file should take preceedence over values picked by Tom Beuzen.
- `./data/raw/profile_features_tom_beuzen/`: This mat file contains dune toes and crests that Tom Beuzen picked out for each profile. This is used as a basis for the toe/crest locations, but is overridden from data contained in `/data/raw/profile_features_chris_leaman`.
- `./data/raw/raw_lidar/`: This is the raw pre/post storm aerial LIDAR which was taken for the June 2016 storm. `.las` files are the raw files which have been processed into `.tiff` files using `PDAL`. Note that these files have not been corrected for systematic errors, so actual elevations should be taken from the `processed_shorelines` folder. Obtained November 2018 from Mitch Harley from the black external HDD labeled "UNSW LIDAR".
- `./data/raw/vol_change_kml/`: This data was obtained from Mitch Harley in Feb 2019 and is a `.kml` showing the change in subaerial volume during the storm. It is included for reference only and is not used in the analysis.
## Notebooks
- `/notebooks/01_exploration.ipynb`: Shows how to import processed shorelines, waves and tides. An interactive widget
plots the location and cross sections.
- `/notebooks/qgis.qgz`: A QGIS file which is used to explore the aerial LIDAR data in `/data/raw/raw_lidar`. By
examining the pre-strom lidar, dune crest and dune toe lines are manually extracted. These are stored in the
`/data/profile_features/`.
- `./notebooks/01_exploration.ipynb`: Shows how to import processed shorelines, waves and tides. An interactive widget plots the location and cross sections.
- `./notebooks/02_collision_protection_volume.ipynb`:
- `./notebooks/03_dune_toe_vs_runup.ipynb`:
- `./notebooks/04a_profile_picker_superseded.ipynb`:

## TODO
- [ ] Raw tide WL's are interpolated based on location from tide gauges. This probably isn't the most accurate method, but should have a small effect since surge elevation was low during this event. Need to assess the effect of this method.
- [ ] Estimate max TWL from elevation where pre storm and post storm profiles are the same. Need to think more about this as runup impacting dune toe will move the dune face back, incorrectly raising the observed twl. Perhaps this estimation of max TWL is only useful for the swash regime.
- [ ] Implement [bayesian change detection algorithm](https://github.com/hildensia/bayesian_changepoint_detection) to help detect dune crests and toes from profiles. Probably low priority at the moment since we are doing manual detection.
- [ ] Implement dune impact calculations as per Palmsten & Holman. Calculation should be done in a new dataframe.
- [ ] Implement data/interim/*.csv file checking using py.test. Check for correct columns, number of nans etc. Testing of code is probably a lower priority than just checking the interim data files at the moment. Some functions which should be tested are the slope functions in `forecast_twl.py`, as these can be tricky with different profiles.
- [ ] Convert runup model functions to use numpy arrays instead of pandas dataframes. This should give a bit of a speedup.
