Risk Calculation
The outputs from the risk calculation in go-coastal (get link) produces a table with the following output variables.
Field | Description | Type |
|---|---|---|
| fd_id | a unique identifier relating the result structure to the NSI structure database | int |
| x | the structure's x location | float64 |
| y | the structure's y location | float64 |
| hazards | all of the hazards experienced by the structure as a json byte blob | byte |
| damcat | the damage category for the structure | string |
| occtype | the occupancy type for the structure, limited to the NSI 40 occupancy types | string |
| s EAD | an estimate of the expected annual damages for structure loss at this structure | float64 |
| c EAD | an estimate of the expected annual damages for the content loss at this structure | float64 |
pop2amu65 | an estimate provided by the NSI for the population at night under the age of 65 | int |
| pop2amo65 | an estimate provided by the NSI for the population at night over the age of 65 | int |
| pop2pmu65 | an estimate provided by the NSI for the population during the day under the age of 65 | int |
| pop2pmo65 | an estimate provided by the NSI for the population during the day over the age of 65 | int |
| found_ht | the foundation height provided by the NSI utilized during the damage compute | float64 |
| <AEF>_S | the structure damage for the <AEF>th event. The combination of each of these records would result in a damage frequency curve that can be integrated to compute EAD reported in s EAD | float64 |
| <AEF>_C | the content damage for the <AEF>th event. The combination of each of these records would result in a damage frequency curve that can be integrated to compute EAD reported in s EAD | float64 |
| <AEF>_H | the hazard for the <AEF>th event. The combination of these at each of the records could be used to create a hazard frequency curve at the structure. The hazard is represented via a json byte blob | byte blob |
The estimate below is based on the best estimate hazards as well as the mean of the various damage functions and uncertainty parameters of the occupancy types, this means that the damage frequency curve created is a representation of the “mean” damage frequency curve with no hazard or consequence uncertainty.
