29 Glossary Alluvial - Transported by water flow processes eg alluvial plain. Aquatic - Living in, growing in, or frequenting water. Aquifer - geological formation or group of formations capable of receiving, storing and transmitting significant quantities of water. Australian Height Datum - The datum used to determine elevations in Australia. This uses a national network of benchmarks and tide gauges and sets mean sea level as zero elevation. Catchment - The area of land which intercepts rainfall and contributes the collected water to surface water (streams, rivers, wetlands) or groundwater. Conductivity - The ability of water to transmit an electrical current. Conductivity is directly related to the abundance of minerals in the water. Discharge - Means the volume rate of loss of water from a river or aquifer through bores and springs. Estuary - An enclosed or semi-enclosed coastal body of water having an open or intermittently open connection to marine waters and fresh input from land runoff which measurably reduces salinity. Water levels vary in response to ocean tides and river flows. Environment - The air, water and land, and the interrelationship that exists among and between water, air, and land and all living organisms. Evaporation - Loss of water from the water surface or from the soil surface by vaporisation. Evapotranspiration (ET) - The combined loss of water by evaporation and transpiration. Floodplain - The portion of a river valley next to the river channel that is or has been periodically covered with water during flooding. Geomorphology - The study of the origin, characteristics and development of land forms. Gigalitre - A commonly used term to measure large quantities of water, equal to 1000 000 000 litres or 1 million cubic metres or 1 million kilolitres (kL). Groundwater - Water that occurs beneath the land surface in the zone(s) of saturation. Hydrologic cycle (water cycle) - The continual cycle of water between the land, the ocean and the atmosphere. Hydrology - The study of water, its properties, distribution and utilisation above, on and below the earth's surface. Recharge - Means the process by which water is added to a zone of saturation, usually by downward infiltration from the surface. Runoff - Water that flows over the surface from a catchment area, including streams. Saturated Zone - The subsurface zone in which all openings are full of water. Significant Adverse Impact - Any impact resulting in degradation of an important resource, that is unacceptable because it cannot be mitigated or because of unacceptable conflicts in management of the use of the impacted resource. Transpiration -The process by which plants take up water from the soil and release water vapour through the leaves. Unsaturated Zone - The subsurface zone, usually starting at the land surface, that contains both water and air. Wetland - Area of seasonal, intermittent or permanent waterlogged soils or inundated land, whether natural or otherwise, fresh or saline, eg. swamp.
