The “Technical Documentation for the Framework for Evaluating Damages and Impacts” document provides technical documentation of a framework used to analyze future climate change-related impacts to the United States, projected to occur across multiple impact sector categories, geo...

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...

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 ...

The National Stormwater Calculator is a simple to use tool for computing small site hydrology for any location within the US. It estimates the amount of stormwater runoff generated from a site under different development and control scenarios over a long term period of historica...

This final report provides an overarching summary of the pilot research project, including the methods used in and the findings of the quantitative and qualitative assessments. It is written to appeal to a wide audience of policy makers, managers, agency staff and the general pub...

Fundamental questions for climate change policy and adaptation strategies are to what extent does ecological risk change under different climate scenarios and how do any changes in risk vary among taxa and geographically. To evaluate these questions, we developed a rule-based fra...

EPA has released the final report titled, <em>Climate Change Vulnerability Assessments: Four Case Studies of Water Utility Practices</em>. This report was prepared by the National Center for Environmental Assessment's Global Climate Research Staff in the Office of Research and D...

EPA announced the release of the final report, <em>BASINs and WEPP Climate Assessment Tools (CAT): Case Study Guide to Potential Applications</em>. This report supports application of two recently developed water modeling tools, the Better Assessment Science Integrating point & ...

Long-term land-use and land cover change and their associated impacts pose critical challenges to sustaining vital hydrological ecosystem services for future generations. In this study, a methodology was developed to characterize hydrologic impacts from future urban growth throug...

As part of a larger investigation into potential impacts of climate change on estuarine habitats in the Pacific Northwest (PNW), we estimated changes in freshwater inputs into four estuaries. These were the Coquille River estuary, the South Slough of Coos Bay, and the Yaquina Bay...

The evolution of the energy system in the United States is an important factor in future environmental outcomes including air quality and climate change. Given this, decision makers need to understand how a changing energy landscape will impact future air quality and contribute ...

EPA has released this draft document solely for the purpose of pre-dissemination peer review under applicable information quality guidelines. This document has not been formally disseminated by EPA. It does not represent and should not be construed to represent any Agency policy ...

Long-term land-use and land cover change and their associated impacts pose critical challenges to sustaining vital hydrological ecosystem services for future generations. In this study, a methodology was developed to characterize hydrologic impacts from future urban growth throug...

This draft report supports application of two recently developed water modeling tools, the BASINS and WEPP climate assessment tools. The report presents a series of short case studies designed to illustrate the capabilities of these tools for conducting scenario based assessments...

Movement of water into and through the vadose zone is of great importance to the assessment of contaminant fate and transport, agricultural management, and natural resource protection. The process of water movement is very dynamic, changing dramatically over time and space. Inf...

This report provides a general overview of EPA’s national MARKAL database and energy systems model and compares various scenarios to a business as usual baseline scenario. Under baseline assumptions, total electricity use increases 1.3% annually until 2030. Annual growth in ele...

This EPA report will illustrate the application of different climate assessment capabilities within EPA’s BASINS modeling system for assessing a range of potential questions about the effects of climate change on streamflow and water quality in different watershed settings and us...
