Flow disturbance
Webof flow disturbance, and by extension, alteration of flow regime on riverine ecosystems has derived primarily from ecological studies of average and high-flow events (Lake 2000). Empirical research into the effects of low flows and drought is increasing rapidly as management of limited water becomes a 1 E-mail addresses: [email protected] To distinguish between the different states of fluid flow one must consider how the fluid reacts to a disturbance in the initial state. These disturbances will relate to the initial properties of the system, such as velocity, pressure, and density.
