In Canada, rainwater harvesting has the potential to impact environmental flows and downstream water users. The hydrological cycle contains surface water, groundwater and rainwater. The effects on the hydrological cycle would be significant if rainwater became an advantageous solution to water quality and availability. [ 2 ]
The list of drainage basins by area identifies basins (also known as "catchments" or, in North American usage, "watersheds"), sorted by area, which drain to oceans, mediterranean seas, rivers, lakes and other water bodies.
Watershed delineation is the process of identifying the boundary of a watershed, also referred to as a catchment, drainage basin, or river basin.It is an important step in many areas of environmental science, engineering, and management, for example to study flooding, aquatic habitat, or water pollution.
Other terms for a drainage basin are catchment area, catchment basin, drainage area, river basin, water basin, [3] [4] and impluvium. [ 5 ] [ 6 ] [ 7 ] In North America, they are commonly called a watershed , though in other English-speaking places, " watershed " is used only in its original sense, that of the drainage divide line.
The Water Survey of Canada (WSC) is a scientific branch of Environment and Climate Change Canada, responsible for monitoring the nation's freshwater resources. The WSC maintains Canada's hydrometric data network, widely referred to as HYDAT. Previously over 2,500 hydrometric gauges were maintained.
The surrounding topography of a catchment zone influences the flow vectors and direction that the water flows. [1] Water flows from areas of high potential energy to low potential energy under the influence of gravity. The geometry of the slope leading to the catchment area influences the amount of water the catchment will contain. [1]
When the response factor A can be determined from the characteristics of the watershed (catchment area), the reservoir can be used as a deterministic model or analytical model, see hydrological modelling. Otherwise, the factor A can be determined from a data record of rainfall and runoff using the method explained below under non-linear reservoir.
The 1987 Federal Water Policy, which remains valid today, has two main goals with respect to water: To protect and enhance the quality of the water resource and to promote the wise and efficient management and use of water. The Canada Water Act (proclaimed on September 30, 1970) provides the framework for cooperation with provinces and ...
