Draindown Assessment

Description

Assess Draindown Rate based on storm size

Usage

marsDraindownAssessment(
  level_ft,
  eventdepth_in,
  designdepth_in,
  storage_depth_ft,
  draindown_hr,
  subsurface = c(TRUE, FALSE)
)

Arguments

level_ft	Observed water level data (ft)
eventdepth_in	Rainfall event depth (in)
designdepth_in	Depth that the SMP is designed to managed (in)
storage_depth_ft	Maximum storage depth of system (ft)
draindown_hr	Draindown calculated by marsDraindown_hr (hr)
subsurface	If the SMP is subsurface, TRUE. If surface, FALSE.

Value

Output is a number based on draindown time and draindown time is rain event was scaled to the design depth. Outputs are codes for the following messages:

5

Draindown is below the target duration, and scaled draindown is below the target duration.

4

Draindown is above the target duration, but scaled draindown is below the target duration.

3

Draindown is below the target duration, but scaled draindown is above the target duration.

2

Draindown is above the target duration, and scaled draindown is above the target duration.

1

Draindown was not calculated.
