Three things you need to know about the New USACE Nationwide Permits

On 3 August 2020, the US Army Corps of Engineers (USACE) announced its intention to issue updated Nationwide permits to replace the 2017 permits. These permits are renewed every five years, so this action is two years early. This unusual move is largely motivated by the problematic Nationwide Permit #12, that is used for utility line crossings. This permit had been temporarily rescinded ...

Balancing Wetland Regulation with Stormwater Management on a Watershed-Wide Basis: A Case Study.

Maryland reconciles rapid growth, water-quality goals, and habitat protection. In response to increasing regulatory authority over its water resources, the Maryland Department of the Environment (MDE) has combined various programs and processes into a 'one-stop shop' where various issues can be addressed in a uniform and consistent manner. As part of this process, onsite conditions are assessed, ...

USGS, NASA Study Finds Widespread Coastal Land Losses from Gulf Oil Spill

A new USGS-NASA study found widespread shoreline loss along heavily oiled areas of Louisiana's coast after the 2010 BP Deepwater Horizon oil spill and compared the erosion from the spill with coastal changes Hurricane Isaac caused in 2012. A pattern of dramatic, widespread shoreline loss along Louisiana’s coast caused by the 2010 BP Deepwater Horizon oil spill has been revealed by a ...

Hydrologic signature analysis of select organic hydric soil indicators in northeastern Florida

The magnitude, duration, and return intervals of surface water flooding and dewatering of the landward extent of the hydric soil indicators muck (LM), histic epipedon (LHE), and Histosol (LH) were quantitatively defined, providing a better understanding of the hydrologic conditions maintaining these hydric soil indicators. Land surface elevations were determined for the LM, LHE, and LH at 16 ...

Position Brief on oil sands mining in Canada

Background The oil sands (also called tar sands) in Canada are the second largest petroleum deposit in the world after Saudi Arabia and underlie about 140,000 square kilometres of land in northern Alberta, composed of woodlands and wetlands. Wetlands cover roughly half the landscape of the oil sands region and a vast majority of these wetlands are peatlands. Oil sands development has profound ...

Development of indices to predict phosphorus release from Wetland soils

Received for publication May 14, 2008. The U.S. Environmental Protection Agency created the Clean Water Action Plan to develop nutrient criteria for four water body types: lakes and reservoirs, rivers and streams, estuaries, and wetlands. Significant progress has been made in open water systems. However, only areas in and around the Florida Everglades have had numeric nutrient criteria set, due ...

Ecotourism: an alternative form of green industry in China

This paper argues that ecotourism with effective management and planning strategies can contribute to the Greening of industry in China. A case study of Hong Kong Wetland Park demonstrates the way in which ecological modernisation is utilised to minimise environmental impacts. One facet of this is environmental education, which is adopted as an effective tool to convert tourist experiences into ...

The future of European floodplain wetlands under a changing climate

In the future, climate change may severely alter flood patterns over large regional scales. Consequently, besides other anthropogenic factors, climate change represents a potential threat to river ecosystems. The aim of this study is to evaluate the effect of climate change on floodplain inundation for important floodplain wetlands in Europe and to place these results in an ecological context. ...

Soil Moisture Applications and Practices Using the HydraProbe Soil Moisture Sensor

Over the past ten years, environmental monitoring has become increasingly important. Environmental factors such as climate change, dwindling water resources, and threatened habitats are driving the need to monitor the environment and implement better policies to protect it. Many natural processes in the environment are driven by or in some ways related soil hydrological processes. Monitoring soil ...

Impact of sedimentation on wetland carbon sequestration in an agricultural watershed

Received for publication January 9, 2008. Landscape redistribution of soil C is common within agricultural ecosystems. Little is known about the effects of upland sediment deposition on C dynamics within riparian wetlands. To assess sedimentation impact, we obtained profile samples of wetland soil and used the combination of 137Cs, 210Pb, and 14C chronological markers to determine rates of C ...

System design and treatment efficiency of a surface flow constructed wetland receiving runoff impacted stream water

This study reported the efficiency of a free water surface flow constructed wetland (CW) system that receives runoff impacted stream water from a forested and agricultural watershed. Investigations were conducted to examine the potential effect of hydraulic fluctuations on the CW as a result of storm events and the changes in water quality along the flow path of the CW. Based on the results, the ...

Diphasic transfer of oxygen in vertical flow filters: a modelling approach

Oxygen renewal, as a prominent phenomenon for aerobic bacterial activity, deeply impacts vertical flow constructed wetland (VFCW) treatment efficiency. The authors introduce a multiphase model able to simulate oxygen transfer in VFCWs. It is based on a two-phase flow module, and a transport module. The transport module is able to deal with convection/diffusion phenomena, inter-phase (air–water) ...

Planning management adapted to climate change effects in terrestrial wetlands and grasslands

Wetlands and grasslands are seriously affected by climate change. A main challenge for agriculture and nature conservation is, in parallel with mitigation, adaptation planning. We started a stakeholder dialogue to develop adaptive management of natural areas in the Körös–Maros National Park (SE Hungary). Impacts that affect terrestrial wetlands and grasslands and their agricultural use and are ...

Position Brief on oil and gas development of the Arctic

Background The Arctic Circle encompasses roughly 6% of the earth’s surface. Wetlands make up about 60% of the total Arctic land mass and are the predominant ecosystem, however they are not well defined or understood. Arctic wetlands provide a wide range of ecosystem services such as the maintenance of permafrost, hydrology and water quality. Arctic wetlands have the highest biological ...

Indicators of wetland acidification and their relevance to environmental impact assessment

Developments in most tropical coastlines are often hampered by acidification, which occurs when sedimentary pyrites are disturbed during construction activities. Acidification causes vegetation die back, fish mortality, heavy metal pollution, corrosion of concrete, steel and other metallic structures. The aim of this study is to develop tools for predicting the likelihood of acidification ...
