Water and Drought
Tracking water availability and drought impacts across scales
Tracking water availability and drought impacts across scales
Water sustains communities, agriculture, and ecosystems — and when drought strikes, the effects ripple across all of them. The USGS monitors water availability, surface water extent, and quality at regional, national, and global scales using remote sensing, watershed modeling, and evapotranspiration data. We track vegetation stress, water use, and drought impacts on wildfire risk, invasive species, land cover change, and ecosystem function. Our work also includes mapping coastal and inland wetlands, giving people, businesses, and agencies the information they need to protect vital resources.

A call to record stormwater control functions and to share network data A call to record stormwater control functions and to share network data
Urban stormwater is an ongoing contributor to the degradation of the health of many watersheds and water bodies. In the United States, federal regulations (e.g., Clean Water Act) require monitoring and reporting of relevant water quality metrics in regulated waterbodies to ensure standards are being met, but decisions about how to manage urban stormwater are left up to state or other...

The presence of denitrifiers in bacterial communities of urban stormwater best management practices (BMPs) The presence of denitrifiers in bacterial communities of urban stormwater best management practices (BMPs)
Stormwater best management practices (BMPs) are engineered structures that attempt to mitigate the impacts of stormwater, which can include nitrogen inputs from the surrounding drainage area. The goal of this study was to assess bacterial community composition in different types of stormwater BMP soils to establish whether a particular BMP type harbors more denitrification potential...

Piloting urban ecosystem accounting for the United States Piloting urban ecosystem accounting for the United States
In this study, we develop urban ecosystem accounts in the U.S., using the System of Environmental-Economic Accounting Experimental Ecosystem Accounting (SEEA EEA) framework. Most ecosystem accounts focus on regional and national scales, which are appropriate for many ecosystem services. However, ecosystems provide substantial services in cities, improving quality of life and contributing...

Hydrologic signals and surprises in U.S. streamflow records during urbanization Hydrologic signals and surprises in U.S. streamflow records during urbanization
Urban development has been observed to lead to variable magnitudes of change for stormflow volume and directions of baseflow change across cities. This work examines temporal streamflow trends across the flow duration curve in 53 watersheds during periods of peak urban development, which ranged from 1939 to 2016. We used U.S. Geological Survey streamgage records combined with pre...

Stormwater control impacts on runoff volume and peak flow: A meta-analysis of watershed modelling studies Stormwater control impacts on runoff volume and peak flow: A meta-analysis of watershed modelling studies
Decades of research has concluded that the percent of impervious surface cover in a watershed is strongly linked to negative impacts on urban stream health. Recently, there has been a push by municipalities to offset these effects by installing structural stormwater control measures (SCMs), which are landscape features designed to retain and reduce runoff to mitigate the effects of...

Seasonal drivers of chemical and hydrological patterns in roadside infiltration-based green infrastructure Seasonal drivers of chemical and hydrological patterns in roadside infiltration-based green infrastructure
Infiltration-based green infrastructure has become a popular means of reducing stormwater hazards in urban areas. However, the long-term effects of green infrastructure on the geochemistry of roadside environments are poorly defined, particularly given the considerable roadside legacy metal contamination from historic industrial activity and vehicle emissions (e.g., Pb). Most current...

Changes in event‐based streamflow magnitude and timing after suburban development with infiltration‐based stormwater management Changes in event‐based streamflow magnitude and timing after suburban development with infiltration‐based stormwater management
Green stormwater infrastructure implementation in urban watersheds has outpaced our understanding of practice effectiveness on streamflow response to precipitation events. Long‐term monitoring of experimental urban watersheds in Clarksburg, Maryland, USA, provided an opportunity to examine changes in event‐based streamflow metrics in two treatment watersheds that transitioned from...

Remote sensing analysis of vegetation at the San Carlos Apache Reservation, Arizona and surrounding area Remote sensing analysis of vegetation at the San Carlos Apache Reservation, Arizona and surrounding area
Mapping of vegetation types is of great importance to the San Carlos Apache Tribe and their management of forestry and fire fuels. Various remote sensing techniques were applied to classify multitemporal Landsat 8 satellite data, vegetation index, and digital elevation model data. A multitiered unsupervised classification generated over 900 classes that were then recoded to one of the 16

Evaluating and monitoring forest fuel treatments using remote sensing applications in Arizona, U.S.A. Evaluating and monitoring forest fuel treatments using remote sensing applications in Arizona, U.S.A.
The practice of fire suppression across the western United States over the past century has led to dense forests, and when coupled with drought has contributed to an increase in large and destructive wildfires. Forest management efforts aimed at reducing flammable fuels through various fuel treatments can help to restore frequent fire regimes and increase forest resilience. Our research...

Influence of governance structure on green stormwater infrastructure investment Influence of governance structure on green stormwater infrastructure investment
Communities are faced with the challenge of meeting regulatory requirements mandating reductions in water pollution from stormwater and combined sewer overflows (CSO). Green stormwater infrastructure and gray stormwater infrastructure are two types of water management strategies communities can use to address water pollution. In this study, we used long-term control plans from 25 U.S...

Stormwater management network effectiveness and implications for urban watershed function: A critical review Stormwater management network effectiveness and implications for urban watershed function: A critical review
Deleterious effects of urban stormwater are widely recognized. In several countries, regulations have been put into place to improve the conditions of receiving water bodies, but planning and engineering of stormwater control is typically carried out at smaller scales. Quantifying cumulative effectiveness of many stormwater control measures on a watershed scale is critical to...
