The roots of the plants take up the nutrients they need, and excess water is collected at the bottom of the wall by a gutter, before being re-injected into the network of pipes: the system works in a closed circuit. Plants are chosen for their ability to grow on this type of environment and depending on available light.
Green roof at the British Horse Society headquarters. A green roof or living roof is a roof of a building that is partially or completely covered with vegetation and a growing medium, planted over a waterproofing membrane. It may also include additional layers such as a root barrier and drainage and irrigation systems. [1]
The panels that comprise a green roof are generally no more than a few centimeters up to 30 cm (a few inches up to a foot) in depth, since weight is an important factor when covering an entire roof surface. The plants that go into a green roof are usually sedum or other shallow-rooted plants that will tolerate the hot, dry, windy conditions ...
Some varieties of flumes are used in measuring water flow of a larger channel. When used to measure the flow of water in open channels, a flume is defined as a specially shaped, fixed hydraulic structure that under free-flow conditions forces flow to accelerate in such a manner that the flow rate through the flume can be characterized by a level-to-flow relationship as applied to a single head ...

Green wall at the Simon Fraser University, Burnaby, British Columbia, Canada.. A green wall is a vertical built structure intentionally covered by vegetation. [1] Green walls include a vertically applied growth medium such as soil, substitute substrate, or hydroculture felt; as well as an integrated hydration and fertigation delivery system.
For a low-maintenance plant wall, opt for moss, preserved houseplants, or air plants that require little to no care. These plants also serve as great black-space fillers to keep your plant wall ...
Water is lost much faster than CO 2 is absorbed, so plants need to replace it, and have developed systems to transport water from the moist soil to the site of photosynthesis. [33] Early plants sucked water between the walls of their cells, then evolved the ability to control water loss (and CO 2 acquisition) through the use of stomata.
