[1] Watershed export of phosphorus (P) from anthropogenic sources has contributed to eutrophication in freshwater and coastal ecosystems. We explore impacts of watershed urbanization on the magnitude and export flow distribution of P along an urban-rural gradient in eight watersheds monitored as part of the Baltimore Ecosystem Study Long-Term Ecological Research site. Exports of soluble reactive phosphorus (SRP) and total P (TP) were lowest in small watersheds with forest and low-density…

Linking Land Use with Water Pollution in Coastal Watersheds of China

Land-water relationship studies are important for watershed and coastal management. Changes in watershed-wide land use may exacerbate water pollution due to non-point source (NPS) and point-source

Contrasting nitrogen and phosphorus budgets in urban watersheds and implications for managing urban water pollution

A comparison of urban watershed nitrogen (N) and phosphorus (P) budgets is presented, underscoring the importance of household actions in influencing urban watershed nutrient budgets and suggesting that N management should emphasize reducing watershed inputs, whereas P management should focus on reducing watershed P inputs and transport from vegetated landscapes to streets and storm drains.

Contrasting influences of stormflow and baseflow pathways on nitrogen and phosphorus export from an urban watershed

Eutrophication of urban surface waters from excess nitrogen (N) and phosphorus (P) inputs remains a major issue in water quality management. Although much research has focused on understanding

Effects of forested floodplain soil properties on phosphorous concentrations in two Chesapeake Bay sub-watersheds, Virginia, USA

The significantly higher values of total P in the stream water and floodplain cut-banks of Sugarland Run suggests erosion and resuspension of previously deposited legacy sediments is an important processes in this human-impacted basin.



Streamflow distribution of non–point source nitrogen export from urban‐rural catchments in the Chesapeake Bay watershed

Nitrogen (N) export from urban and urbanizing watersheds is a major contributor to water quality degradation and eutrophication of receiving water bodies. Methods to reduce N exports using best

Nitrogen Fluxes and Retention in Urban Watershed Ecosystems

AbstractAlthough the watershed approach has long been used to study whole-ecosystem function, it has seldom been applied to study human-dominated systems, especially those dominated by urban and

Effects of Precipitation and Air Temperature on Phosphorus Fluxes from Rhode River Watersheds

We studied fluxes of total P, total phosphate, and total organic P from seven contiguous small watersheds on the Atlantic Coastal Plain in Maryland for up to 25 yr. These watersheds have perched

Net anthropogenic phosphorus inputs: spatial and temporal variability in the Chesapeake Bay region

We estimated net anthropogenic phosphorus inputs (NAPI) in the Chesapeake Bay region. NAPI is an index of phosphorus pollution potential. NAPI was estimated by quantifying all phosphorus inputs and

Hydrology and Chemistry of the Choptank River Basin

The Choptank River basin is a coastal plain catchment dominated by agriculture (52% of land use). We summarize an 11 year data set of discharge and chemistry from a gauged subbasin. Discharge

A watershed perspective on nutrient enrichment, science, and policy in the Patuxent River, Maryland: 1960–2000

The Patuxent River, Maryland, is a nutrient-overenriched tributary of the Chesapeake Bay. Nutrient inputs from sewage outfalls and nonpoint sources (NPS) have grown substantially during the last four
