Remote Sensing of Channels and Riparian Zones with a Narrow-Beam Aquatic-Terrestrial LIDAR
The high-resolution Experimental Advanced Airborne Research LIDAR (EAARL) is a new technology for cross-environment surveys of channels and floodplains. EAARL measurements of basic channel geometry, such as wetted cross-sectional area, are within a few percent of those from control field surveys. The largest channel mapping errors are along stream banks. The LIDAR data adequately support 1D and...
متن کاملIndices for Assessing the Spatial Distribution and Functions of Riparian Buffer Zones
It is widely recognised that riparian zones can greatly reduce the movement of pollutants from hillslopes into streams. While several indices of stream condition exist, the spatial distribution of the pollutant and runoff trapping functions of the riparian zone remains poorly understood. This paper describes three indices, which quantify the spatial distribution of riparian zones that function ...
متن کاملGround Water Nitrate Removal in Subsoil of Forested and Mowed Riparian Buffer Zones
We studied two similar riparian sites in southern New England and examined ground water nitrate (NO~--N) removal in the subsurface of mowed (i.e., herbaceous) v . forested (i.e., woody) vegetation. Each site consisted of poorly drained, fine to medium sands and contained adjacent areas of mowed and forested vegetation. We dosed mesocosms with bromide and lSN labeled NO~-N amended ground water t...
متن کاملTitle: Supply of an ecosystem service—Farmers’ willingness to adopt riparian buffer zones in agricultural catchments
In the European Union, mitigation measures to abate diffuse pollution from agricultural land are implemented under the direction of the EU Nitrates and Water Framework Directives. As these measures are implemented in national policies, a review process will look at the efficacy of the measures with a view to recommending further measures as necessary and following scientific and stakeholder con...
متن کاملNumerical simulation of nanofluids flow and heat transfer through isosceles triangular channels
Nanofluids are stable suspensions of nanoparticles in conventional heat transfer fluids (base fluids) that exhibit better thermal characteristics compared to those of the base fluids. It is important to clarify various aspects of nanofluids behavior. In order to identify the thermal and hydrodynamic behavior of nanofluids flowing through non-circular ducts, in the present study the laminar flow...
