Streamside Management Zone Delineation for Control of Non-Point Source Pollution
Riparian areas are critical interfaces between aquatic and terrestrial ecosystems. Protecting and enhancing them by implementing streamside management zones (SMZs) is an essential practice of sustainable forestry. SMZs provide ecological functions including protection against non-point source pollution, promotion of water infiltration, contribution of beneficial nutrients and coarse woody debri...
متن کاملStreamside Management Zone Effectiveness for Protecting Water Quality Following Forestland Application of Biosolids
Biosolids, materials resulting from domestic sewage treatment, are surface applied to forest soils to increase nutrient availability. Retaining streamside management zones (SMZs) can limit nutrient pollution of streams. We delineated 15 m SMZs along three intermittent streams in an 18-year-old Pinus taeda L. plantation. We applied biosolids outside the SMZ on one side of each of the streams mai...
متن کاملSurf zone surface retention on a rip-channeled beach
[1] The retention of floating matter within the surf zone on a rip-channeled beach is examined with a combination of detailed field observations obtained during the Rip Current Experiment and a three-dimensional (3-D) wave and flow model. The acoustic Doppler current profiler–observed hourly vertical cross-shore velocity structure variability over a period of 3 days with normally incident swell...
متن کاملAssessment of Streamside Management Zones for Conserving Benthic Macroinvertebrate Communities Following Timber Harvest in Eastern Kentucky Headwater Catchments
Headwater streams generally comprise the majority of stream area in a watershed and can have a strong influence on downstream food webs. Our objective was to determine the effect of altering streamside management zone (SMZ) configurations on headwater aquatic insect communities. Timber harvests were implemented within six watersheds in eastern Kentucky. The SMZ configurations varied in width, c...
متن کاملElectroosmotic flow control and surface conductance in capillary zone electrophoresis.
Electroosmotic flow within capillary zone electrophoresis can be altered electronically through a mechanism modeled as surface conductance. Experimentally, a small zone of conductive silver on the outer surface of the capillary is shown to permit good control of electroosmotic flow with an applied external voltage. This control is modeled as capacitance across the capillary wall and conductance...
