Adaptation: Calculate impact adaptation option for time horizon

[MatthiasHauthDeltares]

Input

• Generic economical inputs (climate factor, f_init and discount rate)
• calculated impact (losses+damages) for the event from the step: Adaptation: run and combine Losses and Damages for adaptation options for event #596

Process

The impact per event needs to be converted into an impact for the time horizon. For every link in network:

• Calculate array of frequencies of event for every year in time horizon corrected with climate factor: p(t) = f_init + climate_factor * t)
• Calculate array of impact for every year in time horizon: Impact(t) = Impact_event * p(t) / (1+discount_rate)**t
• Sum the impact per year into total impact. Add this result to geopackage with column name Net_present_mpact_option_{ID}
