Introduction

This repository contains the codes for the Geo-INQUIRE tool to compute the rainfall-induced landslide hazard over an area. This verison of the code can assume a constant 24-h rainfall acummulation over the entire area covered by the susceptibility map, or use a user-provided map with the 24h rainfall acummulations over the area covered by the susceptibility map.

Precipitation-induced landslide hazard is one of the services included in the GEO-INQUIRE Virtual Access to products enabling curiosity-driven science for geohazard and multi-risk assessment (see https://www.geo-inquire.eu/virtual-access/geohazard-and-multi-risk-assessment for details).

Getting Started

1. Installation process: The landslide hazard tool requires to have installed python and Poetry.
2. Software dependencies: Python version and dependecies are specified in the Poetry .toml file.

REQUIRED INPUT DATA AND FILES:

Input files must be saved (before running the hazard tool) in the ../Data/ folder: - input_variables.csv: csv file where the mode and input rainfall can be specified. - *_sus.tif : Tile of the susceptibility map over hazard will be computed. Must be downloaded from map repository. - StdMaxDayRain.txt: Standard deviation of the maximum daily rainfall.

RUN THE HAZARD TOOL:

1. In place the tile of the susceptibiluty map covering the area you want to compute the hazard in the folder ./Tool-Hazard-Map/input.

2. In the case of wanting to use a spatial-variable rainfall map place it in the folder the folder ./Tool-Hazard-Map/input. The map needs to be in ".tif" format, cover the area of the susceptibility map and use the WGS84 (EPSG: 4326) projection.

3. Modify the input_variables.csv excel: 3.3. Select mode; "constant" if you desire to apply a constat user-specified rainfall acummulation over an area. "map" if you desire to use your own rainfall map. 3.4. In case of using the mode "constant" specify the 24 h rainfall acummulation in [mm] over the area. 3.5. In case of using teh mode "map" specify the name of the .tif file containing the rainfall map (without the file extension).

4. The code you need to runn is stored in ./Tool-Hazard-Map/Code folder

5. Before you runn the code make sure you have activated the poetry enviroment: poetry shell

6. From the ./Tool-Hazard-Map/Code folder in the terminal run: python Hazard.py

7. The outpurs are stored in the ../Results/constant/ folder.

OUTPUT:

Results from the Hazard Tool are saved in the following folder which is authomatically generated ../Results/constant/

1. Rainfall Hazard: Rainfall hazard class in .tif format. Saved as: ./RainHazard/*_RainHazard.tif
2. Hazard map: in .tif format. Saved as: ./Hazard/*_Hazard.tif
