Use of geochemical mass balance modelling to evaluate the role of weathering in determining stream chemistry in five mid-atlantic watersheds on different lithologies
Autor: Margaret M. Kennedy, R. Todd Anderson, Owen P. Bricker, Karen C. Rice, Anne K. O'brien
Publikováno v: Hydrological Processes. 11:719-744
The importance of mineral weathering was assessed and compared for five mid-Atlantic watersheds receiving similar atmospheric inputs but underlain by differing bedrock. Annual solute mass balances and volume-weighted mean solute concentrations were c

PRESENCE AND DISTRIBUTION OF TRACE ELEMENTS IN NEW JERSEY STREAMBED SEDIMENTS 1
Autor: Anne K. O'brien
Publikováno v: JAWRA Journal of the American Water Resources Association. 33:387-403
The distribution of trace elements in New Jersey streambed sediments is described with respect to physiographic provinces and major drainage areas. Samples were collected during 1976–1993 at 295 sites distributed throughout New Jersey. Copper, chro

Episodic acidification of a coastal plain stream in Virginia
Autor: Anne K. O'brien, K. N. Eshleman
Publikováno v: Water, Air, and Soil Pollution. 89:291-316
This study investigates the episodic acidification of Reedy Creek, a wetland-influenced coastal plain stream near Richmond, Virginia. Primary objectives of the study were to quantify the episodic variability of acid-base chemistry in Reedy Creek, to

Determination of contributing areas for saturation overland flow from chemical hydrograph separations
Autor: Keith N. Eshleman, John S. Pollard, Anne K. O'brien
Publikováno v: Water Resources Research. 29:3577-3587
A recurring problem in watershed hydrology is the identification of flow paths along which water is routed in both surface and subsurface environments. In particular, the question of whether storm flow is composed primarily of water flowing over the

Comparison of episodic acidification of Mid-Atlantic Upland and Coastal Plain streams
Autor: Anne K. O'brien, Margaret M. Kennedy, Owen P. Bricker, Karen C. Rice
Publikováno v: Water Resources Research. 29:3029-3039
Episodic acidification was examined in five mid-Atlantic watersheds representing three physiographic provinces: Coastal Plain, Valley and Ridge, and Blue Ridge. Each of the watersheds receives a similar loading of atmospheric pollutants (SO42− and
