Automated Geospatial Watershed Assessment Tool (AGWA)
The Automated Geospatial Watershed Assessment (AGWA) tool is a GIS-based multipurpose hydrologic analysis system for use by watershed, water resource, land use, and biological resource managers and scientists in performing watershed- and basin-scale studies. It uses readily available spatial data sets to parameterize and run two widely used watershed runoff and erosion models: the Soil Water Assessment Tool (SWAT) and KINematic Runoff and EROSion (KINEROS2) hydrologic models. AGWA is designed to support hydrologic modeling and watershed assessments at multiple spatial and temporal scales.
Richly illustrated, Portland continues its unique approach to neighborhood revitalization with this "holistic, adaptable and flexible" plan for redeveloping a large riverfront brownfields site. Heavy emphasis on natural features.
This paper details the health benefits of exposure to natural environments. It cites research by an international panel of scientists assembled by Harvard under the auspices of its Natural Environments Initiative in the School of Public Health.
With annual rainfall averaging 7 inches, and the most common event dropping .2 inches, Phoenix's approach to green infrastructure differs [!] from Seattle's. Given arid climate and poorly-drained soil, their goals emphasize preservation of native tree species, little consideration of rain barrels, cisterns, green roofs.
This tool provides an index of the most extreme temperatures, precipitation events, and droughts from around the country to aid planners and policy makers in the adaptation process.
