As the urban landscape and municipal infrastructure in U.S. cities changes in response to socio-economic conditions, so does the manner in which water cycles through these cities. The modulation of hydrologic processes (e.g., runoff, infiltration, evapotranspiration) by land use and land cover has implications for resilience, sustainability, and optimizing municipal service functions. The U.S. Geological Survey and U.S. Environmental Protection Agency, Office of Research and Development, collaborated to address the question of how Legacy (standard) and recent (Urban Greening Program or "Green") vacant lots – each the product of a certain approach to the widespread practice of demolition – differ in terms of how...

In 1968, the Missouri Geological Survey (MGS) established the Operation Basement program to address three objectives: a) to obtain drill hole and underground mining data relative to the structure and composition of the buried Precambrian basement; b) to expand mapping in the Precambrian outcrop area and conduct research related to Precambrian geology and mineral resources; and c) to publish the results of the first two objectives in the Contribution to Precambrian Geology series (Kisvarsanyi, 1976). The database presented here represents the first of those objectives. It was originally compiled in close cooperation with exploration and mining companies operating in Missouri, who provided drillhole data, core and...

The U.S. Geological Survey developed two steady-state finite-difference regional groundwater-flow models using the MODFLOW-NWT computer code. These models simulate flow in the area of historical iron mining on and around the portion of the Mesabi Iron Range that is in the St. Louis River basin in northeastern Minnesota. The models are composed of 8 layers each; the upper four representing unconsolidated glacial sediments and the lower 4 representing bedrock. Horizontal boundary flows for these models are the results of a 2-dimensional analytic element groundwater-flow model of the entire St. Louis River Basin documented here: https://doi.org/10.3133/sir20195033 and available here: https://doi.org/10.5066/P9KUJ0L3....
