The JAWRA Journal of the American Water Resources Association (JAWRA) publishes original research that examines the multidisciplinary and complex issues surrounding water resources.

Papers often cover the topics of recent AWRA conferences such as riparian ecology, geographic information systems, adaptive management, and water policy.

A survey of non-USGS continuous streamflow gaging networks in the Pacific Northwest

A survey of non-USGS continuous streamflow gaging networks in the Pacific Northwest

Number of unique organizations that identified that they operate streamflow gages in each watershed. We found as few as two and up to 16 organizations that operate streamflow gages in a given watershed (e.g., Lower Snake), while other watersheds may only have relatively few organizations operating streamflow gages (Southern Oregon Coastal).

Maryland counties overlaid on the 2016 National Land Cover Database (Dewitz, 2019). The Region of Interest (mid-Atlantic states) and Area of Interest (shaded) are shown in the inset map

Spatial Analysis of Future Climate Risk to Stormwater Infrastructure

Spatial Analysis of Future Climate Risk to Stormwater Infrastructure

Median percent change for 100-year, 10-year, 2-year, and 90th percentile precipitation events circa 2050. Note the historical baseline for volumes 1 and 2 incorporate observed data through 2000; volumes 6, 8, and 9 use observations through 2010/2012; volume 10 uses data through 2012/2015, and volume 11 uses data through 2018.

Wellfield Optimization to Minimize Contaminant Migration from a Surficial to a Semi-Confined Aquifer Using Numerical Modeling
Building resilience to extreme weather and climate events in the rural water and wastewater sectors

Building resilience to extreme weather and climate events in the rural water and wastewater sectors

Communities surveyed in western Alaska (left) and southern Louisiana (right). Note that there are no major road systems between the rural hub communities in Alaska, as these communities are only accessible by air or water.
