Reservoir

Class Description

A water storage facility within a hydro system, including: ponds, lakes, lagoons, and rivers. The storage is usually behind some type of dam.

Attributes

Name Type Description
activeStorageCapacity Volume Storage volume between the full supply level and the normal minimum operating level.
energyStorageRating Float The reservoir’s energy storage rating in energy for given head conditions.
fullSupplyLevel WaterLevel Full supply level, above which water will spill. This can be the spillway crest level or the top of closed gates.
grossCapacity Volume Total capacity of reservoir.
normalMinOperateLevel WaterLevel Normal minimum operating level below which the penstocks will draw air.
riverOutletWorks String River outlet works for riparian right releases or other purposes.
spillTravelDelay Seconds The spillway water travel delay to the next downstream reservoir.
spillwayCapacity Float The flow capacity of the spillway in cubic meters per second.
spillwayCrestLength Length The length of the spillway crest.
spillwayCrestLevel WaterLevel Spillway crest level above which water will spill.
spillWayGateType String Type of spillway gate, including parameters.
