A geospatial deep learning framework for scalable hydrographic mapping
… sustainability. In the 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 …

Assessing the Effect of Wetland Connectivity on In-Stream Nitrate Concentrations Using an Integrated Wetland-River Network
… information for wetlands and waterways are the National Wetlands Inventory and the National Hydrography Dataset, respectively. These were not inherently made to be compatible. A method was created to combine these two datasets, which outputs an integrated wetland-river network complex that can …

Does Urbanization Facilitate the Establishment of Introduced Monk Parakeet (Myiopsitta monachus) Populations?
… percent impervious surface data from the 2016 National Land Cover Database GIS layers, surface water features from the National Hydrography Dataset, and observations and location data from eBird to find nest locations that were then confirmed by Google Street View. I created buffered areas …

Geoprocessing Approaches to Delineate Impoundments and Characterize Subcatchments within Kansas Reservoir Drainages
… are substantial. Kansas exhibits a unique hydrography by having some of the highest densities of small impoundments in the United States. Previous studies have highlighted the potential of impoundments to act as significant sinks for sediment. However, their significance within Kansas …

Ecological Limitations and Potentials of Artificial Aquatic Systems
… in well-used federal aquatic databases; the National Hydrography Dataset only included one on a “CanalDitch” flow line, and the National Wetlands Inventory only included two within “partially drained/ditched” areas, and none as individual “excavated” features. Others were mis-categorized, but …
