Functions

func CanalRecharge

func CanalRecharge(v *database.Setup) (err error)

CanalRecharge is a function to get the recharge amounts from the diversions and apportion them to the Canal sections and recharge them into the groundwater model.

func Conveyance

func Conveyance(v *database.Setup) (err error)

Conveyance function finds the diversions and calculates the conveyance loss for all cells where there is a canal. This outputs to the results table in sqlite. Might update to return delivery by canal.

func GetSurfaceWaterDelivery

func GetSurfaceWaterDelivery(v *database.Setup) (map[int]Diversions, error)

GetSurfaceWaterDelivery function returns a map with a key of year and a value of slice of Diversion that is a monthly amount of surface water delivered to an acre of land. The units of the Diversion are in acre-feet per acre for use in subsequent processes.
