Dissolved phosphorus export from an animal waste impacted in-stream wetland: response to tropical storm and hurricane disturbance.

Mitigating Urban Wetland Impacts on Downstream Water Resources

Wetlands in older urban areas have often been integrated into stormwater management systems and exhibit severe degradation from receiving decades of untreated and uncontrolled urban runoff. Vegetative diversity is often poor and dominated by a few hardy species such as cattail (Typha latifolia) or reed canary grass (Phalaris arundinacea). These wetlands may also be affected by legacy impacts fr...

Dissolved Phosphorus Transport during Storm and Base Flow Conditions from an Agriculturally Intensive Southeastern Coastal Plain Watershed

The high density of animal production in southeastern Coastal Plain watersheds has caused some soils to contain excess amounts of plant–available soil phosphorus (P). Runoff, erosion, and leaching can transport P to surface water systems and out of these watersheds. High P concentrations in downstream aquatic ecosystems can increase the risk of eutrophication. Our objectives were to determine s...

Transport of Nitrate and Ammonium During Tropical Storm and Hurricane Induced Stream Flow Events from a Southeastern USA Coastal Plain In-Stream Wetland

In-stream uptake dampens effects of major forest disturbance on watershed nitrogen export.

Between January 4 and 10, 1998, a severe ice storm impacted large areas of northern New York, New England, and eastern Canada. This storm struck the Hubbard Brook Experimental Forest in New Hampshire on January 7-8, 1998, and caused extensive forest crown damage (>30%) in a narrow elevation band (600-740 m) across the south-facing experimental watersheds. Stream water has been collected and che...

Changes in the concentration, biodegradability, and fluorescent properties of dissolved organic matter during stormflows in coastal temperate watersheds

[1] Dissolved organic matter (DOM) transport during storms is studied because it is important in the annual watershed export budget for dissolved organic carbon (DOC). We sampled stream water from two watersheds (upland and wetland-dominated) and three subcatchments (bog, forested wetland, and mineral forest) located within the wetland-dominated watershed during a fall and summer storm to inves...
