Cumulative Impacts of Stream Restoration on Watershed-Scale Flood Attenuation, Floodplain Inundation, and Nitrate Removal
Severe flooding and excess nutrient pollution, exacerbated by heightened anthropogenic pressures (e.g., climate change, urbanization, land use change, unsustainable agricultural practices), have been detrimental to riverine systems and their estuaries. The degradation of riverine systems can …

Impact of Stream Restoration on Flood Attenuation and Channel-Floodplain Exchange During Small Recurrence Interval Storms
Extreme flooding and excess nutrient pollution have been detrimental to river health under increased environmental stress from human activities (e.g., agriculture, urbanization). Riverine flooding can be detrimental to human life and infrastructure yet provides important habitat and ecosystem …

Watershed Scale Impacts of Floodplain Restoration on Nitrate Removal and the Practical Applications of Modeling Cumulative Floodplain Restoration Hydraulics
… river functions such as nutrient processing and flood attenuation. Floodplain restoration increases floodplain exchange and is commonly implemented to improve water quality and reduce flood impacts at watershed scales. However, the effect of multiple restoration projects at the watershed scale is …

Riparian resilience in the face of interacting disturbances: understanding complex interactions between wildfire, erosion, and beaver (Castor canadensis) in grazed dryland riparian systems of low order streams in North Central Washington State, USA
… such as diverse habitat for numerous species, flood attenuation and essential water storage in water limited environments. These systems have experienced long term disturbance from anthropogenic activities including mining, timber harvest, livestock grazing and near extirpation of a keystone …

A framework for determining remote sensing capabilities for ecosystem services valuation
… is demonstrated on a case study focused on the flood attenuation function (service) provided by wetlands. Water budget models are utilized to identify essential parameters for monitoring water storage by wetlands. Using a study area encompassing the Fall Lake Creek reservoir (Oregon, USA), water …

Are all wetland models the same? Comparing wetland models and streamflow regulation of catchment-scale hydrological modelling tools under a changing climate
… of streamflow regulation, e.g., storing flood water and reducing high flows and releasing water in drier periods, which may or may not be realistic for a given area. Evaluating wetland models is critical for navigating the different types of physical wetlands with variable influences on …

A novel approach for large-scale flood risk assessments
In the past, floods were basically managed by flood control mechanisms. The focus was set on the reduction of flood hazard. The potential consequences were of minor interest. Nowadays river flooding is increasingly seen from the risk perspective, including possible consequences. Moreover, the …

Evaluating the impacts of urbanization and stormwater management practices on stream response
… impact on conveyance capabilities and loss of flood attenuation due to disconnectivity from floodplains. These relationships were shown for the North Carolina Piedmont, but are also applicable throughout the United States.

Vegetation dynamics in a semi-arid freshwater wetland: a measure for restoration success
… freshwater wetland is the largest inland flood plain found in the semi-arid region of South Africa and a Ramsar site of worldwide conservation importance. It provides a habitat to some endangered species; however, it is facing degradation problems leading to a declining of its …
