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...

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...

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 ...

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...

This report uses results from a previous report titled <em>Assessment of the Impacts of Global Change on Regional U.S. Air Quality: A Synthesis of Climate Change Impacts on Ground-Level Ozone</em>, a number of high-resolution, spatially explicit population projections developed ...

Aquifer recharge (AR) is a technical method being utilized to enhance groundwater resources through man-made replenishment means, such as infiltration basins and injections wells. Aquifer storage and recovery (ASR) furthers the AR techniques by withdrawal of stored groundwater at...

The Watershed Management Optimization Support Tool (WMOST) is a decision support tool that facilitates integrated water management at the local or small watershed scale. WMOST models the environmental effects and costs of management decisions in a watershed context, accounting fo...

Executive Summary Environmentally responsible development of oil and gas assets requires well-developed emissions inventories and measurement techniques to verify emissions and the effectiveness of control strategies. To accurately model the oil and gas sector impacts on air qual...

EPA announced the availability of the draft report, <em>Updates to the Demographic and Spatial Allocation Models to Produce Integrated Climate and Land Use Scenarios (ICLUS)</em> for a 30-day public comment period. The ICLUS version 2 (v2) modeling tool furthered land change mod...

EPA's announced the availability of the final report, <em>Updates to the Demographic and Spatial Allocation Models to Produce Integrated Climate and Land Use Scenarios (ICLUS)</em> (Version 2). This update furthered land change modeling by providing nationwide housing developmen...

EPA announced the availability of the final report, <i>Aquatic Ecosystems and Global Change: The Challenges of conducting Multi-Stressor Global Change Vulnerability Assessments</i>. This report investigates the issues and challenges associated with identifying, calculating, and ...
