- Social Stratification Indices
- Social Stratification Indices, 1970, Gwynns Falls Watershed, Baltimore, Maryland - The selection of variables and indices for the classification of block groups used the theoretical parameters identified by Logan and Molotch (1987), Choldin (1984) and Bullard (1990) in addition to adjustments recommended by Johnston (1976), Murdie (1976), and Hamm (1982). This method has been applied and tested previously for a number of cities in the United States. These earlier studies indicated that this social areas approach was appropriate for measuring residential social stratification (Bogue and Bogue 1976; Johnston 1976; Murdie 1976; Bogue 1984a; Bogue 1984b; Frisbie and Kasarda 1988). In order to construct the indices, socio-economic and household data were obtained from the 1970, 1980, and 1990 Census. - Metadata

- Streamflow and Stream Chemistry -- Overview and Metadata
- Longitudinal sites along the Gwynns Falls
- Boundary Station 1. Gwynns Falls at Glyndon. This site samples drainage from approximately 96 ha of suburban land at the headwaters of our main study stream.

[Chemistry (Text)] [Chemistry (Spreadsheet)]
- Boundary Station 2. Gwynns Falls at Gwynnbrook/Delight. This site samples drainage from approximately 1,000 ha of old and new suburban and suburbanizing land use.
[Site Location, Photographs, Equipment (USGS)] [Current Streamflow Data (USGS)]
[Chemistry (Text)] [Chemistry (Spreadsheet)]
- Boundary Station 3. Gwynns Falls at Villa Nova. This site samples drainage from approximately 7,400 ha of old and new suburban and suburbanzing land use. Streamflow at this station has been monitored continuously by the USGS since 1957 (with a hiatus from 1988 - 1995). This station is the boundary between the urban and suburban portions of the Gwynns Falls.

[Chemistry (Text)] [Chemistry (Spreadsheet)]
- Boundary Station 4. Gwynns Falls at Route 1/Carroll Park. This sites samples drainage from approximately 16,000 ha of mixed suburban and urban watershed. The site has been monitored by USGS since 1994 and represents the boundary condition for entire Gwynns Falls above head of tidal influence. This station allows for evaluation of the urban portion of the Gwynns Falls watershed by comparison with the Gwynns Falls at Villa Nova station (station #3 above).

- Cub Hill sites. The “Cub Hill” site is 14 km from the Baltimore city center (39°24'30.20"N, 76°30'50.62"W) and is the location of the first permanent urban carbon flux tower in an urban/suburban environment, established in 2001 by the U.S. Forest Service. Three long-term stream monitoring sites were established in the residential area in the footprint of the tower; Jennifer Branch at North Wind Rd. (JBNW) and two headwater tributaries to Jennifer Branch: Harford Hills (JBHH) and Ontario (JBON).

- Watershed 263 subwatersheds. Watershed 263 is a 364 ha urban storm drain watershed (or sewershed), with 30,000 residents with mixed industrial, institutional, and residential land uses. In March 2004, we established long-term monitoring sites in two sub-watersheds within W283. Both are approximately 17 ha, with 20% impervious surface and 4% vegetation cover. Samples (weekly grab and flow-weighted composite) are taken in a stormwater drainage pipe.

Topography
|
- National Elevation Dataset (NED) BES subset - The USGS National Elevation Dataset (NED) has been developed by merging the highest-resolution, best-quality elevation data available across the United States into a seamless raster format. NED is the result of the maturation of the USGS effort to provide 1:24,000-scale Digital Elevation Model (DEM) data with NAD83 datum for the conterminous US and Hawaii, and 1:63,360-scale DEM data with NAD27 datum for Alaska. - Metadata
- Shuttle Radar Topography Mission (SRTM) Elevation Dataset - Note: This an initial release of the SRTM dataset, errors do exist. The Shuttle Radar Topography Mission (SRTM) aboard the Space Shuttle Endeavour, launched on Feb. 11, 2000. SRTM was assigned to collect 3-D measurements of the Earth's surface. - Metadata
- Light Detection and Ranging (LIDAR) Dataset (not yet available online) - Two Digital Elevation Models interpolated from LIDAR ground points and LIDAR first pulse points. This data set was interpolated using the natural neighbor interpolation method within the ArcGIS 3D Analyst Extension.
