Alluvial Fan
Fan shaped terrestrial deposit of alluvial sediment, which forms as sediment load is deposited because of a reduction in the stream gradient.

With reference to water.

An underground formation that stores groundwater.

Basin (Watershed)
Land area from which water drains towards a common point.

The measurement of the depth of bodies of water.

Rock at or near the Earth’s surface that is solid and relatively unweathered.

Property boundary.

To check, adjust, or determine by comparison that a computer model will produce results that meet or exceed some defined criteria within a specified degree of confidence.

The modification of consumer demand for water through various methods, such as financial incentives or education.

Drip Irrigation / Drip Systems
A water-saving irrigation method that allows water to drip slowly to the roots of plants.

Drought Response Plan
A strategy that outlines the actions to be taken before, during, and immediately after a drought to reduce its impacts.

A system in which populations of species group together into communities and interact with each other and the abiotic environment.

The process by which water changes from a liquid to atmospheric water vapour – an essential part of the water cycle.

The combined processes of evaporation and transpiration.

Fracture-Flow System
A bedrock aquifer in which the flow takes place primarily within fractures in bedrock.

Water existing below the ground surface in aquifers.

The area or natural environment in which an organism or population normally lives.

Hydraulic Conductivity
A measure of the ability of a soil or bedrock or unconsolidated aquifer to transmit a fluid such as water, that depends on properties of both the medium and the fluid.

Hydraulics deals with the mechanical properties of liquids. Free surface hydraulics and open channel flow are branches of hydraulics used to describe the properties of free surface flow, such as the flow in rivers.

Adjective of the noun hydrogeology.

The geology of groundwater, with particular emphasis on the chemistry and movement of water.

Adjective of the noun hydrology.

The science dealing with the properties, distribution, and circulation of water.

Hydrometric Network
A network of stations that measure water level and streamflow.

In-stream Use
Water use taking place within a stream channel, such as hydroelectric power generation, navigation, recreational activities, and fish propagation and use.

Instream Flow
Water flowing in a stream.

Instream Flow Management
Managing or maintaining minimum flows in rivers and streams to provide a certain level of environmental protection.

Instream Flow Needs
The flow of water in a natural watercourse required to support and sustain fish and other aquatic dependent species.

Irrigation Scheduling
The process used by irrigation system managers to determine the correct frequency and duration of watering.

Litre. There are 1,000 L in a cubic metre, and 1,000,000 L in a cubic decameter (dam3). 1,000,000 L = 1 ML

Adjective of the noun limnology.

Scientific study of physical, chemical, and biological conditions in lakes, ponds, and streams.

Liquid Waste Management Plan (LWMP)
A written record of a community’s decisions and plans for dealing with liquid wastes, including sewer discharges, storm-water runoff, sewer overflows, sewage treatment plant sludge, effluent, septic tanks, and more.

A description of the data in a source, distinct from the actual data. An item of metadata may describe an individual datum, or content item, or a collection of data including multiple content.

Megalitre. One ML = 1,000,000 litres, i.e. 1 dam3

Naturalized Flow
Flows that would have existed without human use or management.

Locations at which surface water properties are reported, such as the mouths of tributaries.

Offstream Use
Water withdrawn or diverted from a ground- or surface-water source for use.

The place where a sewer, drain or stream discharges.

Vertical movement of water from the surface to the subsurface.

Refers to water entering a groundwater aquifer through percolation from the surface or through lateral movement from an adjacent upslope aquifer.

Regional Growth Strategy (RGS)
A local government strategic plan to promote sustainable human settlement and efficient use of public facilities, land and other resources.

An artificial lake used to store water.

Of, belonging to, or characteristic of the family Salmonidae, which includes salmon, trout, and whitefish.

Saturated Hydraulic Conductivity
The hydraulic conductivity that exists when the medium is saturated.

The flow of water in a river or stream channel.

Stream-Flow Naturalization
The process of estimating the stream-flow that would exist in the absence of human water management activities.

Surface Flows
Open channel flow, or the gravity-driven flow of water above the ground.

Surface Water
Water that flows in streams and rivers, and exists in natural lakes, wetlands, and in reservoirs.

The relief exhibited by a surface.

Loss of water vapour from plants.

Unconsolidated Aquifer
An aquifer that exists in an unconsolidated deposit.

Unconsolidated Deposit
Loosely arranged or unstratified sediment whose particles are not cemented together.

Water Balance
The flow of water in and out of a system.

Water Demand
Water use determined using an estimation approach, such as a model.

Water Licence
A licence issued by the B.C. government to store water, or to withdraw water from a surface water source for a particular purpose.

Water Use
Volume or rate of water diverted or withdrawn from a water body (eg a stream, lake, or groundwater aquifer) for use by humans on the land surface. Actual water use is determined through direct measurement. Water demand is an estimate of actual water use.

Water Use Area
An area of the land surface which obtains water from a common location or locations.

Watershed (Basin)
Land area from which water drains towards a common point.
