Dissolved organic carbon dynamics in a riparian aquifer: effects of hydrology and nitrate enrichment.
The capacity of riparian soils to remove nitrate (NO3) from ground water is well established, but the effects of ground water NO3(-)-enrichment on C dynamics are not well studied. We incubated horizontal cores of aquifer material extracted from beneath moderately well-drained (MWD) and poorly drained (PD) soils in a riparian forest in Rhode Island, USA for 132 d, and dosed (flow rate, 170 mL d(...
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...

امروزه سالیتون ها بعنوان امواج جایگزیده ای که تحت شرایط خاص بدون تغییر شکل در محیط منتشر می-شوند، زمینه مطالعات گسترده ای در حوزه اپتیک غیرخطی هستند. در این راستا توجه به پدیده پراش گسسته، که بعنوان عامل پهن شدگی باریکه نوری در آرایه ای از موجبرهای جفت شده، ظاهر می گردد، ضروری است، زیرا سالیتون های گسسته از خنثی شدن پراش گسسته در این سیستم ها بوسیله عوامل غیرخطی بوجود می آیند. گسستگی سیستم عامل...
Nitrate Dynamics in Riparian Forests: Groundwater Studies
This study was conducted to assess the removal of groundwater nitrate (NOa-) in different soil drainage classes within three riparian forests located in Rhode Island. A solution of NOa-and a conservative tracer [either bromide (Br-) or chloride (CI-)] was applied in growing and the dormant seasons to trenches upgradient of wetland locations with hydric soils (poorly and very poorly drained soil...
متن کاملNitrate Dynamics in Riparian Forests: Microbial Studies
While riparian forests have a demonstrated ability to remove nitrate (NO3-) moving from uplands before it enters streams, there is considerable uncertainty as to the mechanisms of NOr removal in these areas. We characterized spatial and temporal variation in denitrification enzyme activity (DEA), microbial biomass C and N content, soil respiration and potential net N mineralization and nitrific...
