RISK COMPONENTS

1. flood_events: inundation reports for multiple rain events between 2010 and 2013 as kindly provided by EPT Ltd.

2. exposure
	a. Res_exposure.shp: Residential exposure contains the number (agg_number) and value (agg_struct) of residential buildings from Open Street Maps and GEM
	b. gadm41_VNM_2.shp: Administrative boundary (level 2/Districts)
	c. HCMC_population_2019_4326.shp: Census data (level 3/Wards)
	
3. inundation_data: Raster files (TIF) of return period maps (1, 10, 25, 50, 100 years) for 3 hour precipitation; BC1 and BC2 correspond to the presence and absence of retention basins.

4. look_up: Loss model lookup table from Kasra Rafiezadeh Shahi, Nivedita Sairam, Lukas Schoppa, et al.

[id: unique combination of variables; wd: discrete water depth categories in cm; dur: discrete duration categories in hours; 
 elev: whether the building is elevated (0/1); renov: time since last renovation - discrete categories in years; fe: Flood experience in discrete categories;
 loss_interval: discrete relative loss categories; loss_avg	prob: interpolation of the loss category]

5. loss_output: Shape files of loss values corresponding to the return period maps (1, 10, 25, 50, 100 years)
