The groundwater-surface water (GW-SW) ecotone, or hyporheic zone, is an active component of stream ecosystems that influences whole-system metabolism and nutrient retention. Because hydrologic fluxes affect the supply of carbon, nutrients, and oxygen to the GW-SW ecotone, the biogeochemical structure of the ecotone (i.e., nutrient content) and the role of the ecotone in nutrient retention are. Interstitial water, faunal samples, and hydrogeological data were collected beneath a riffle on the Speed River, southern Ontario, Canada. The purpose was to identify the location and seasonal fluctu.

Groundwater movement in a near-surface local system generally sinks down at recharge areas and loops up at discharge areas. In contrast, groundwater movement in a deep regional system generally flows laterally toward the direction of decreasing gradient.

Aquifers. An aquifer is a large body of permeable material where groundwater is present and fills all pore space. Good aquifers are those with high permeability such as poorly cemented sands, gravels, or highly fractured rock. An aquitard is a body of material with very low permeability. In general, tightly packed clays, well cemented sandstones, and igneous and metamorphic rocks lacking. A. General References. 1. Fundamentals of Ecology, 5th P. Odum and Gary W. Barrett.

The ecotone concept is used to consider exchanges of matter and energy between groundwater and surface water systems. Ecotones control these exchanges by acting as a combination of three types of filter: the contrast between permanent darkness and day-night alternation produces a photic filter; the matrix of interstitial underground systems creates a mechanical filter which slows down water Cited by: of permeability are governed by hydrology, whereas between a surface system and a partially clogged aquifer with small substrate pore size, they are governed by aerobic and anaerobic processes.

According to the degree of permeability, ecotones can be classified as either permanent or temporary sinks for the two adjacent systems.

The exchange patterns between old groundwater and surface water have implications on the subsurface system's alimony, i.e. food and oxygen supply (sensu Hahn, ).Generally, temperature variation, organic matter and dissolved oxygen will decrease with subsurface residence time and passage distance (Malard et al., ).While older groundwater is largely stripped of nutrients and organic Cited by: The groundwater-surface water (GW-SW) ecotone, or hyporheic zone, is an active component of stream ecosystems that influences whole-system metabolism and nutrient retention.

Fish apparently are both excellent indicators of ecotone quality as well as determiners of its structure and function. Pumping can affect the level of the water table.

Groundwater occurs in the saturated soil and rock below the water table. If the aquifer is shallow enough and permeable enough to allow water to move through it at a rapid-enough rate, then people can drill wells into it and withdraw water.A perspective on the permeability of the surface freshwater-groundwater ecotone.
