How Rivers Work - The Role of Groundwater
This video, produced by the UK Groundwater Forum, helps explain the important role that groundwater plays in the environment. The video shows the contribution groundwater makes to the flow in Britain’s rivers and in doing so provides some basic information on groundwater, subsurface dynamics and the hydrological cycle as a whole.
The video is 16 minutes long, and uses graphics and 3-D animation to aid explanations. It will be of value to all those interested in groundwater and hydrology. It also provides a useful tool for teaching the issues relating to the water cycle, sustainable development and the environment for schoolchildren at Key Stages 3 and above.
Specific issues addressed by the video are:
- the role rivers play in society
some simple statistics on rainfall and river flow
the hydrological cycle
how groundwater flows within aquifers
definition of key groundwater terms
location of major aquifers at outcrop and role of groundwater in public water supplies
flow of groundwater to rivers and range of residence times within the aquifer
effect of natural fluctuations in the water-table on river flow
effect of pumping groundwater on river flow
problems associated with low-flowing rivers
other impacts on rivers from man’s activities
