Database structuration

The network configuration should contains:

• the list of hydraulic nodes of the system: locations where inflows and outflows occur. Each point has at least an unique identifier. Description fields and geomatic information could be added in the future.
• the nature of the point: run-off or flow
• as we assume that the network is only constituted with confluences, the identifier of the next downstream hydraulic node should be provided.

For hydraulic nodes of nature "run-off", we need some more informations:

• area of the water basin
• the hydrological model used

Times series:

• need to be stored in one matrix containing each time step in lines and all fields in columns in accordance with tidyverse specifications.
• a vector with the timestamps should be associated with the data (in a list?).

Proposition of structuration in a list with:

• an entry date containing the vector of timestamps
• one entry for each hydraulic node identified by the id of the node with a matrix containing all associated data.
