Stream restoration strategies for reducing river nitrogen loads
© The Ecological Society of America www.frontiersinecology.org N (N) is vital to the functioning of aquatic ecosystems, yet can be extremely detrimental in excess. Elevated levels of N moving down streams and rivers are of particular concern for coastal areas, due to problems associated with eutrophication (Howarth et al. 2002). While agricultural and urban best management practices (BMPs) cont...
متن کاملQuantifying Macroinvertebrate Responses to In-Stream Habitat Restoration: Applications of Meta-Analysis to River Restoration
The assumption that restoring physical habitat heterogeneity will increase biodiversity underlies many river restoration projects, despite few tests of the hypothesis. With over 6,000 in-stream habitat enhancement projects implemented in the last decade at a cost exceeding $1 billion, there is a clear need to assess the consistency of responses, as well as factors explaining project performance...
متن کاملRiver restoration
[1] River restoration is at the forefront of applied hydrologic science. However, many river restoration projects are conducted with minimal scientific context. We propose two themes around which a research agenda to advance the scientific basis for river restoration can be built. First, because natural variability is an inherent feature of all river systems, we hypothesize that restoration of ...
متن کاملRiver Restoration and Meanders
Among the most visually striking river restoration projects are those that involve the creation of a new channel, often in a new alignment and generally with a form and dimensions that are different from those of the preproject channel. These channel reconstruction projects often have the objective of creating a stable, single-thread, meandering channel, even on rivers that were not historicall...
متن کاملSustainability and River Restoration
One of the major problems causing the accelerating widespread destruction and degradation of the natural environment is the undervaluing of the protection and restoration of environmental resources that takes place in the decision making process. This paper argues that non-market values need to be incorporated in the benefit estimation process to make the concept of sustainability operational u...
