The United States Environmental Protection Agency (US EPA) conducts extensive research to enhance the scientific foundation for national environmental decision-making. In this context, US EPA has developed COMET (City-based Optimization Model for Energy Technologies) to capture t...

EPA/ORD developed City-based Optimization Model for Energy Technologies (COMET) which is designed to examine energy consumption and management scenarios under various environmental policy scenarios implemented at city- and state-level. Initial application of the COMET is piloted ...

The Scenarios and Interpretive Science Coordinating Group (SISCG) is an interagency coordinating group, supporting the U.S. Global Change Research Program (USGCRP). The SISCG convened the Towards Scenarios of U.S. Demographic Change Workshop in Rockville, Maryland on June 23 and ...

We reviewed the available social-ecological, hydrological, and geochemical literature for the ecological systems of the San Juan Bay Estuary (SJBE), a site in the Environmental Protection Agency’s National Estuarine Program. The objective of the review is to gather in one place a...

Like many coastal communities, the City of Crisfield, Maryland, is experiencing increased inundation due to sea level rise (SLR), land subsidence, and intensifying extratropical storms. The U.S. Environmental Protection Agency (EPA) Office of Research and Development (ORD) has pa...

This is the report produced from the workshop, "Understanding Decision-Relevant Regional Climate Data Products", that was convened in November 2023 by DOE. The workshop included Federal, state, and academic experts in producing, evaluating, and applying regional climate...

This is a multidisciplinary scientific report that details how future operations of Glen Canyon Dam will impact the biophysical landscape of Grand Canyon and the Colorado River. The report is being prepared by the USGS and delivered to the U.S. Bureau of Reclamation. The USGS is ...

The purpose of this report is to respond to EPA's identified need for an improved understanding of the potential impacts of changes in long term weather conditions on the occurrence and management of urban stormwater runoff. EPA conducted continuous simulation modeling of the hy...

This report summarizes the results of the Coastal Integrated Hydro-Terrestrial Modeling (C-IHTM) Workshop that was co-planned, co-hosted and attended by the MultiSector Dynamics (MSD) community, a collective of university- and national lab-based researchers who work on the modeli...

The goal for this report was to examine current municipal solid waste (MSW) management infrastructure of Davenport, Iowa and provide scenarios with resilience, sustainability, and equity considerations in mind. The City of Davenport, Iowa was selected as the project site through ...

Flooded lands are defined as water bodies where human activities have 1) caused changes in the amount of surface area covered by water, typically through water level regulation (e.g., constructing a dam), 2) waterbodies where human activities have changed the hydrology of existin...

This draft Geographic Information System (GIS) tool can be used to generate scenarios of housing-density changes and calculate impervious surface cover for the conterminous United States. A draft User’s Guide accompanies the tool. This product distributes the population project...

This workshop report describes a workshop sponsored by the Chesapeake Bay Program (CBP) Science and Technical Advisory Committee (STAC) titled “Chesapeake Bay Program Climate Change Modeling 2.0”. The workshop was held in late 2018, and brought together over 40 scientists to give...

This report is a revision of the earlier 2017 CRSI report. The report renames the index to the Cumulative Resilience Screening Index to avoid the confusion associated with the earlier moniker Climate Resilience Screening Index. Both retain the CRSI acronym and are the ostensibly ...

The Watershed Management Optimization Support Tool (WMOST) was developed by the United States Environmental Protection Agency (US EPA) to facilitate integrated water resources management. The new Benefits Module for WMOST enables stakeholders to calculate the value of additional ...

This report “National Water Infrastructure Adaptation Assessment: Part II, Smart Urban Designer (SUD) and Case Studies” is a part of the research effort undertaken by the EPA Office of Research and Development (ORD) Water Systems Division (WSD) on national water infrastructure as...

Over the last 40 years, Narragansett Bay has experienced significant water quality improvements in response to reductions in nitrogen, heavy metal and organic contaminants, and bacterial pathogen discharge. The sources of these pollutants stem from the long history of population ...

Fish communities in river networks provide significant ecosystem services that will likely decline under future land use, human water demand, and climate variability. Modeling can be used to assess the consequences to multiple populations of one or more fish species from multiple...

The Fertilizer Emission Scenario Tool for CMAQ (FEST-C v1.4) is a Java-based interface system that facilitates the integration of agriculture, atmosphere, and hydrology simulations at large scales through the current release of the Spatial Allocator (SA v4.3.2) Raster Tools syste...

This report covers wood stove testing carried out by ORD during May 2018 to June 2018. Testing and analysis was completed as of October 2018. Three stoves of varying design and certification level were tested using the Black Carbon Protocol developed by the International Cryosphe...

The Tri-State Mining District (TSMD) encompassing the Kansas, Missouri and Oklahoma conjunction was the center of historic mining activity, ceasing in 1970. Although mining activity ended almost 50 years ago, its legacy as a source of cadmium, lead, and zinc to the environment c...

The Global Change Assessment Model (GCAM) is an integrated assessment model that links the world's energy, agriculture and land use systems with a climate model. The model is designed to assess various climate change policies and technology strategies for the globe over long tim...

The United States Environmental Protection Agency's (EPA) Water Modeling Workgroup (WMW) provides support for core surface water quality modeling tools used in Clean Water Act programs. The WMW identified a set of 18 separate surface water modeling applications that are currently...
