Effects of Stream Order and Data Resolution on Sinuosity Using GIS
… the VBMP Hydro44 and National Hydrography Data (NHD). Insufficient statistical evidence was found to support the hypothesis that the computed sinuosity values using Hydro44 and NHD data are different from EMAP field data for all 55 streams. Sinuosity values computed using Hydro44 and NHD were …

Geoprocessing Approaches to Delineate Impoundments and Characterize Subcatchments within Kansas Reservoir Drainages
… solely on the National Hydrography Dataset (NHD). The two DEM-based methodologies resulted in the identification of features absent in the NHD, and accuracy testing showed both DEM-based methodologies produce more accurate surface area geometries. In turn, the two approaches can be used to …

A geospatial deep learning framework for scalable hydrographic mapping
… United States, the National Hydrography Dataset (NHD) provides the authoritative spatial framework for surface water representation, yet its reliance on manual interpretation and rule-based workflows limits the timeliness and consistency of updates across diverse landscapes. Traditional hydrologic …

Flow Dynamics in Large River Basins: Self -Similar Network Structure and Scale Effects
… obtained from the national hydrographic dataset (NHD). The effect of hillslope dynamics on the different variance-producing mechanisms has been also described and analyzed. It was found that the hillslope dynamics tends to counteract the effect of geomorphologic dispersion, that is, the hillslopes …

Modulation of the immune response by current and novel treatments for hepatitis C virus
… production of IFN? from pDCS from both CHC and NHD patients but also TNF?, IL8 and IL10. In MoDCs from NHDs, ribavirin decreased CD40L-induced TNF? production but had no effect on other cytokines tested or on DC phenotype. These findings explain possible reasons behind the failure of monotherapy …

Breaking Down Microtubule Formation: Characterizing the Biochemical and Cellular Functions of the γ-Tubulin Ring Complex
… domains of GCP6, named the N-helical domains (NHD) and the "belt"domain, are needed to maintain the structural integrity of the γ-TuRC, and that without these domains, specific components of the complex are lost. Cells expressing these N-terminally truncated GCP6 constructs displayed partial …

Environmental and Digital Data Analysis of the National Wetlands Inventory (NWI) Landscape Position Classification System
The National Wetlands Inventory (NWI) is the definitive source for wetland resources in the United States. The NWI production unit in Hadley, MA has begun to upgrade their digital map database, integrating descriptors for assessment of wetland functions. Updating is conducted manually and some …
