## Welcome to floodam.agri

**floodam.agri** is an R library for producing flood damage functions for cultivated plot (agriculture).

This library has been developed within the French working group “GT AMC” which aims at developing methodologies for the economic appraisal of flood management policies (Agenais et al. 2013 ; Brémond et al. 2022). In this context, the development of **floodam.agri** has received the support of the French Ministry in charge of the Environment. Further development of the library was supported by the Labex AGRO 2011-LABX-002 as part of the CAFRUA project n°2101-027.

## What **floodam.agri** can do

**floodam.agri** is based on a model of agricultural plots.

**floodam.agri** includes a collection of elementary damage components that describe how elementary components may be impacted in terms of monetary damage when flooded in specific conditions.

From this information, **floodam.agri** can calculate the following outputs:

- different type of damage functions:
- absolute damage functions to specific crops at plot level
- absolute damage functions to type of crops at plot level

## What **floodam.agri** cannot do

**floodam.agri** cannot (and is not intended to):

- calculate damage from the intersection of hydraulic modeling, land use modeling and damage functions. This is what
**floodam.spatial**does. - calculate damage at the farm level by taking into account interactions between plots, buildings and equipment. This is what
**AVA**does.

**floodam.agri** cannot (but should at some point be able to) :

- calculate the uncertainty of damage functions
- perform a sensitivity analysis of damage functions
- calculate damage functions at farm level
