The Total Maximum Daily Load (TMDL) program, established by the Clean Water Act, is used to establish limits on loading of pollutants from point and nonpoint sources necessary to achieve water quality standards. One important use of a temperature TMDL is to allocate thermal loads...

COFFEE will evaluate the environmental impacts of implementing various COF practices by using the amount of total ecosystem C (TEC) sequestered in forests as the integrative response metric. These evaluations will be done for current-climate and future-climate scenarios and will...

In 2007 the Oregon legislature created a new Oregon Climate Change Research Institute (OCCRI), which is based at Oregon State University (OSU). As part of its charter, OCCRI is mandated to produce a biennial report for the state legislature synthesizing climate change impacts a...

This final report is a technical "best practices" document describing sensor deployment for and collection of continuous temperature and flow data at ungaged sites in wadeable streams. This document addresses questions related to equipment needs; configuration, placement, and ins...

As part of the Climate Ready Estuaries (CRE) program, the Global Change Research Program (GCRP) in the National Center for Environmental Assessment, Office of Research and Development at the U.S. Environmental Protection Agency has prepared a report exploring a new methodology fo...

The report “National Water Infrastructure Adaptation Assessment” is comprised of four parts (Part I to IV), each in an independent volume. The Part I report presented herein describes a preliminary regulatory and technical analysis of water infrastructure and regulations in the ...

Better Assessment Science Integrating Point and Nonpoint Sources (BASINS 4.1) is a program developed by the US EPA for local, regional, and state agencies responsible for water resources management, particularly, the development of total maximum loads (TMDLs) as required under th...

The Watershed Management Optimization Support Tool (WMOST) is a decision support tool that evaluates the relative cost-effectiveness of management practices at the local or watershed scale. WMOST models the environmental effects and costs of management decisions in a watershed c...

Multiple drivers, including nutrient loading and climate change, affect the Narragansett Bay ecosystem in Rhode Island/Massachusetts, USA. Managers are interested in understanding the timing and magnitude of these effects, and ecosystem responses to restoration actions. To provid...

BASE (Basin-Scale Assessments for Sustainable Ecosystems) is a research program developed by the Ecosystems Research Division of the National Exposure Research Laboratory to explore and formulate approaches for assessing the sustainability of ecological resources within watershed...

Land surface hydrology controls runoff production and the associated transport of sediments, and a wide variety of anthropogenic organic chemicals, and nutrients from upland landscape areas and hillslopes to streams and other water bodies. Based on interactions between landscape ...

Recent studies have indicated that solar radiation can be a significant stressor of coral assemblages in tropical and subtropical marine environments. Here we review the scientific literature related to the interactions of solar radiation with coral reefs, with emphasis on harm...

Coral reefs are declining at unprecedented rates worldwide due to multiple interactive stressors including climate change and land-based sources of pollution. The Clean Water Act (CWA) can be a powerful legal instrument for protecting water resources, including the biological inh...

Using historic air photos and U.S. Coast Survey maps, historic vegetation changes were identified. Using surveys of vegetation and elevation, we measure elevation of Narrow River salt marshes, and compare it with other salt marshes in Rhode Island and neighboring states. Water ...

Over the last 60 years, the Chesapeake Bay water quality and seagrass beds have diminished to the point that the system is less able to support abundant crabs and diverse fish, feed waterfowl, and produce safe recreational opportunities. Further, the long-term resilience of the B...

Global climate change affects the fundamental drivers of the hydrological cycle. Evidence is growing that climate change will have significant ramifications for the nation&rsquo;s freshwater ecosystems, as deviations in atmospheric temperature and precipitation patterns are more ...

In this report we present an analysis of water benefits from an array of observed green roof and control (non-vegetated) roof project sites throughout NYC. The projects are located on a variety of building sites and represent a diverse set of available extensive green roof instal...

This draft report reviews available literature on climate change effects on aquatic invasive species (AIS) and examines state level AIS management activities.

This draft report is a preliminary assessment that describes how biological indicators are likely to respond to climate change, how well current sampling schemes may detect climate-driven changes, and how likely it is that these sampling schemes will continue to detect impairment...

The purpose of this draft report is to provide a summary of climate change impacts to selected watersheds and recommendations for how to improve the process of conducting watershed assessments in the future.

This external review draft report is a technical "best practices" document describing sensor deployment for and data collection of continuous temperature and flow at ungaged sites in wadeable streams. This document addresses questions related to equipment needs; configuration, pl...
