Channel straightening and levee construction eliminate these areas of deposition, creating unfavorable conditions for riparian vegetation recruitment. By preventing overbank flooding, levees reduce the amount of water available to riparian vegetation in the floodplain, which alters the types of vegetation that can persist in these conditions. [ 2 ]
Another is the fact that channelized streams are almost invariably straightened. For example, the channelization of Florida's Kissimmee River has been cited as a cause contributing to the loss of wetlands. [5] This straightening causes the streams to flow more rapidly, which can, in some instances, vastly increase soil erosion.
Robinson Creek in Boonville, California, had highly eroded stream banks prior to initiation of a stream restoration project.. Stream restoration or river restoration, also sometimes referred to as river reclamation, is work conducted to improve the environmental health of a river or stream, in support of biodiversity, recreation, flood management and/or landscape development.
A wide variety of river and stream channel types exist in limnology, the study of inland waters.All these can be divided into two groups by using the water-flow gradient as either low gradient channels for streams or rivers with less than two percent (2%) flow gradient, or high gradient channels for those with greater than a 2% gradient.
Leak channels account for the natural permeability of the membrane to ions and take the form of the equation for voltage-gated channels, where the conductance is a constant. Thus, the leak current due to passive leak ion channels in the Hodgkin-Huxley formalism is I l = g l e a k ( V − V l e a k ) {\displaystyle I_{l}=g_{leak}(V-V_{leak})} .
Membrane channels are a family of biological membrane proteins which allow the passive movement of ions (ion channels), water or other solutes to passively pass through the membrane down their electrochemical gradient. They are studied using a range of channelomics experimental and mathematical
Analysis Utility Branch Dose–response curves: Graph that shows the magnitude of the response of an organism, as a function of exposure (or doses) to a stimulus or stressor (usually a chemical) after a certain exposure time [2]
Two-pore channels were analyzed by using cell biological methods, endolysosomal patch clamp techniques, and a variety of other methods to study their functions. From these, it was suggested that TPCs have some power in controlling the luminal pH in endolysosomal vesicles.
