  • Hydrological drought amplifies wildfires in Borneo’s humid tropics

    The area of wildfires in Borneo during drought years turns out to be ten times larger than during non-drought years, an international research team reports in Nature Climate Change of this week. The fires recurrently affecting Borneo’s humid tropical ecosystems have negative influence on the biodiversity and lead to large CO2 emissions, affecting atmospheric composition and regional climate ...

  • Preliminary results from investigation of injection wells at Lahaina wastewater facility

    The U.S. Environmental Protection Agency released preliminary results from an ongoing investigation by federal and state agencies to evaluate the fate of effluent from the Lahaina Wastewater Reclamation Facility near the Kaanapali coast of Maui. According to the interim report one of two tracer dyes introduced in the wells was detected at the coastal seeps, located roughly one-half mile southwest ...

  • Bacterial persistence in streams, say SSSA

    A research team from the University of Tennessee (UT) has completed a study on an East Tennessee river to determine the connection between watershed hydrology and fecal bacteria statistical time series analysis. Shesh Koirala and colleagues report their findings in the July-August issue of the Journal of Environmental Quality. The article presents a study of the temporal patterns and statistical ...

  • New model simulates US groundwater and surface water interactions

    A new model to simulate groundwater and surface water interactions has been released by the U.S. Geological Survey (USGS). The groundwater and surface water FLOW (GSFLOW) model simultaneously accounts for climatic conditions, runoff across the land surface, subsurface flow and storage, and the connections among terrestrial systems, streams, lakes, wetlands, and ground water. 'GSFLOW can be used ...

  • Miami Conservancy District of Ohio receives NGWA Special Recognition Award

    The Miami Conservancy District in southwest Ohio has received a 2014 Special Recognition Award from the National Ground Water Association. The Special Recognition Award is presented to an individual or organization that demonstrates dedication, service, and commitment to the groundwater industry and community through involvement and achievement on a local or regional level.

  • Predicting drainage impacts

    Predicting the drainage impacts on downstream peak events is complex because it involves studying many physical processes at different interdependent scales: the individual field, the drainage network, and the catchment. This group of researchers from France and North Carolina performed an experiment performed in a small subsurface-drained catchment (130 ha), east of Paris, France. The main ...

  • Future of water and hydrogeologic investigations focal points of 2018 McEllhiney lectures

    Looking at the disparity between water data and how water sources are developed is one of the topics being offered to selected hosts during the 2018 William A. McEllhiney Distinguished Lecture Series in Water Well Technology. A second presentation deals with how collecting high-density electrical data allowing for new advancements in hydrogeology illustrates that significant changes to ...

  • The critical role of groundwater in alpine hydrogeology focus of 2018 Darcy lecture

    Alpine hydrogeology is gaining new understanding as nearly half of the world’s population relies on water supplies that originate in high mountains. The variety of these environments and their challenges will be discussed during the 2018 Henry Darcy Distinguished Lecture Series in Groundwater Science given by Dr. Masaki Hayashi. Source areas of mountain streams have rugged topography with ...

  • Urban trees enhance water infiltration

    Global land use patterns and increasing pressures on water resources demand creative urban stormwater management. Traditional stormwater management focuses on regulating the flow of runoff to waterways, but generally does little to restore the hydrologic cycle disrupted by extensive pavement and compacted urban soils with low permeability. The lack of infiltration opportunities affects ...

  • Future of water from River Nile threatened by climate change

    One scenario set out by climatologists is that global warming in Egypt could speed up the Nile river evaporation process and lead to a decline in freshwater supplies, exacerbating the country’s acute shortage of water for drinking, irrigation and hydro-electric generation.  Such a scenario could also have serious socio-economic consequences, one of which could be that Egypt might not be able to ...

  • Seeps important in watershed nitrogen retention

    Globally, the mobilization of nitrogen has increased significantly due to human activities, such as industrial and agricultural development. As a result, over the past decades, eutrophication in coastal ecosystems has increased. Watershed nitrogen retention is an important mechanism to decrease nitrogen loading to downstream water bodies. Generally, in the northeastern U.S., the amount of ...
