VolumeToElevation

Syntax

VolumeToElevation(Volume) or
VolumeToElevation(Reservoir, Volume)

Description

Converts a reservoir volume to a reservoir elevation, using the Reservoir Volume Elevation Curve. If the reservoir parameter is not included, then the current reservoir will be used. Note: the volume given must be in the unit specified for reservoir volume and the resulting elevation will be in the unit specified for reservoir elevation (see General Area Parameters, Units).

Examples

You want to model a water conservation program that starts (reducing demand by 15%) when the reservoir elevation drops below a critical level (20 m). Here is the expression for \Demand Sites\South City:DSM Reduction

  If( VolumeToElevation( Supply and Resources\River\Weaping River\Reservoirs\Central Reservoir, PrevTSValue(Supply and Resources\River\Weaping River\Reservoirs\Central Reservoir:Storage Volume[Million m^3] )) < 20,
    15%,
    0)

Note: for this example, it would actually be easier to get the result value for elevation directly (no need to convert volume to elevation), using PrevTSValue(Supply and Resources\River\Weaping River\Reservoirs\Central Reservoir:Storage Elevation.
