Object Type Vocabulary

A term for describing a built or natural water system component .

Term Name Definition
Wetland Wetland Land where saturation with water is the dominant factor determining the nature of soil development and the types of plant and animal communities living in the soil and on its surface (Cowardin, December 1979). Wetlands are found from the tundra to the tropics and on every continent except Antarctica. Wetlands are areas that are inundated or saturated by surface or groundwater at a frequency and duration sufficient to support, and that under normal circumstances do support, a prevalence of vegetation typically adapted for life in saturated soil conditions. Wetlands generally include swamps, marshes, bogs and similar areas. Wetlands may be forested or unforested, and naturally or artificially created.
WastewaterTreatmentPlant Wastewater treatment plant A facility where wastewater is treated to reduce concentrations of dissolved and (or) suspended materials prior to discharge or reuse.
Stream Stream A body of running water moving under gravity flow in a defined channel. The channel may be entirely natural, or altered by engineering practices through straightening, dredging, and (or) lining. An entirely artificial channel should be qualified with the "canal" or "ditch" secondary site type.
Site Site a generic site
ReturnFlow Return flow could be a node or link represents water returning from a demand site like an agriculture area to a specific location on a river
Reservoir Reservoir An inland body of standing fresh or saline water that is generally too deep to permit submerged aquatic vegetation to take root across the entire body (cf: wetland). This site type includes an expanded part of a river, a reservoir behind a dam, and a natural or excavated depression containing a water body without surface-water inlet and/or outlet.
Network Network A group of nodes and links that share a property (s) and could have a set of attributes that apply to all of it like cost of water, evaporation etc
MonitoringSite Monitoring site a location where time series data of variables are measured
HydroelectricPlant Hydroelectric plant A facility that generates electric power by converting potential energy of water into kinetic energy. Typically, turbine generators are turned by falling water.
Headflow Headflow tributary flowing into a river
Groundwater Groundwater An Aggregate Groundwater Withdrawal/Return site represents an aggregate of specific sites whe groundwater is withdrawn or returned which is defined by a geographic area or some other common characteristic. An aggregate groundwatergroundwater site type is used when it is not possible or practical to describe the specific sites as springs or as any type of well including 'multiple wells', or when water-use information is only available for the aggregate. Aggregate sites that span multiple counties should be coded with 000 as the county code, or an aggregate site can be created for each county.
Diversion Diversion a node or link site where water is withdrawn or diverted from a surface-water body (e.g. the point where the upstream end of a canal intersects a stream, or point where water is withdrawn from a reservoir). Includes sites where water is pumped for use elsewhere.
DemandSite Demand site An Aggregate Water-Use Establishment represents an aggregate class of water-using establishments or individuals that are associated with a specific geographic location and water-use category, such as all the industrial users located within a county or all self-supplied domestic users in a county. The aggregate class of water-using establishments is identified using the national water-use category code and optionally classified using the Standard Industrial Classification System Code (SIC code) or North American Classification System Code (NAICS code). An aggregate water-use establishment site type is used when specific information needed to create sites for the individual facilities or users is not available or when it is not desirable to store the site-specific information in the database. Data entry rules that apply to water-use establishments also apply to aggregate water-use establishments. Aggregate sites that span multiple counties should be coded with 000 as the county code, or an aggregate site can be created for each county.
Connection Connection water lost due to infiltration or evaporation etc
Catchment Catchment A catchment area is a hydrological unit. Each drop of precipitation that falls into a catchment area eventually ends up in the same river going to the sea if it doesn’t evaporate. However, it can take a very long time. Catchment areas are separated from each other by watersheds. A watershed is natural division line along the highest points in an area. Catchments are divided into sub catchments, also along the lines of elevation.
Canal Canal An artificial watercourse designed for navigation, drainage, or irrigation by connecting two or more bodies of water; it is larger than a ditch.
