A 3 d period was chosen for consecutive sampling on the basis of the mean annual hydraulic residence times in the nontidal
portions of the major streams in the system.
All 18 lagoons are nontidal
permanently closed off systems; variations in salinity are mainly attributed to seawater intrusions that overtop the lagoon's sand barrier during sea storms.
harrisii with immature embryos can be transplanted from nontidal
to tidal conditions and vice versa, and the rhythm (circadian or circatidal) in larval release changes to that of crabs in the new estuary (Forward et al., 1982).
virginica, and other marsh plants may be found in nontidal
habitats (seasonal marsh) if soil salinities and moisture conditions are suitable (e.g., Ferren 1985; Ferren et al.
Growth, production, food consumption and mortality of juvenile spot and croaker: a comparison of tidal and nontidal
1981) (holding that an owner of land along the shorelines of navigable nontidal
waters--in this case, Clear Lake--had title to land between the high and low water marks, but that the title was subject to the public trust); State v.
Palustrine wetlands are defined as all nontidal
wetlands dominated by trees, shrubs, persistent emergents, emergent mosses, or lichens and all such wetlands that occur in tidal areas.
Forest operations conducted in accordance with BMPs can use such management as a defense against claims of water quality standard violations.(155) In Maryland, agricultural operations must employ BMPs under soil conservation district plans to protect nontidal
wetlands.(156) Similar requirements are imposed on agriculture in the Chesapeake Bay watershed.(157) Federal law can compel the implementation of BMPs, particularly on federal lands.(158) In addition, states can independently force the federal government to make its financial assistance programs, permits, licenses, and development projects conform with state nonpoint control programs, which may feature BMPs.(159)
wetlands, the average annual duration of flooding is called the hydroperiod, which is based on the presence of surface water and not its depth.
In recent studies, bull chubs were a dominant component of the fish community in the nontidal
James River (Garman et al., 1991; Garman and Nielsen, 1992).
The SHA will be creating 74 acres of nontidal
and tidal wetlands on a 138-acre parcel of land owned by the Anne Arundel County Department of Recreation and Parks.
redistribution of atmospheric, nontidal
oceanic, soil and snow cover masses), need to be removed from the GPS time series.
