environmental footprint
A measure of environmental impact based on the distance that resources for a development are transported.
environmental management
A management agreement for an area or project set up to plan and make sure the declared management objectives for the area or project are met. Environmental Management Plans are often undertaken as part of an environmental impact assessment and are set out in several stages with responsibilities clearly defined and environmental monitoring procedures in place to show compliance with the plan.
evapotranspiration
The process by which the Earth's surface or soil loses moisture by evaporation of water and by uptake and then transpiration from plants.
extended detention basin
A detention basin in which the runoff is stored beyond the time normally required for attenuation. This provides extra time for natural processes to remove some of the pollutants in the water. |
