  • Watershed Project Presents Challenges

    Dennis McAlpine, P. E., project engineer at Houston Engineering, Inc. (HEI) acknowledges he enjoys a professional challenge. He has one. And so do several other folks connected with a $3 million water management project to clean up lakes in the Rice Creek Watershed District (RCWD), as well as other projects. The district is in the north/northeast sector of the metropolitan area and includes parts ...

  • Monitoring watershed health

    Background Municipal water quality managers recognize the need for data that can be used to monitor and assess the impact of urbanization on the condition of natural watersheds. Storm events, in conjunction with the alteration of native landscape, building of roads and overuse of fertilizer, can contribute to excess nutrients, sediment and other pollutants in environmentally significant ...

  • Characterization of phosphorus sources in rural watersheds

    Received for publication February 21, 2008. Correct identification of P sources in rural watersheds is critical for the development of cost-effective measures to combat agriculturally-driven eutrophication. The chemical composition of various storm runoff types (field surface runoff, field drain outfalls, roads, farmyards, and septic tanks) and the receiving streams in three micro (<10 km2) ...

  • EVALUATING HSPF IN AN ARID, URBANIZED WATERSHED

    The Hydrologic Simulation Program-FORTRAN (HSPF) is a powerful time variable hydrologic model that has rarely been applied in arid environments. Here, the performance of HSPF in southern California was assessed, testing its ability to ...

  • Sizing mitigation wetlands in agricultural watersheds

    In this study, we investigated use of microcosms to supplement field studies for establishing the size of wetlands required to mitigate nitrate pollution in agricultural watersheds. Wetlands investigated in this study were located in San Joaquin Valley (California, USA) and demonstrated mean nitrate-nitrogen mass removal efficiencies ranging between 10 and 34%. Mean areal nitrate removal ...

  • Sewage Treatment – Small System in a Watershed

    ABSTRACT:Water purveyors, in examining their watersheds, have raised concerns over small community pollution sources, particularly over phosphorus, nitrogen, pathogens and suspended solids. As our population has increasingly moved further upstream in watersheds, the application of classic sewage treatment plants (STPs) have been pushed to their limit of design, especially in light of the need by ...

  • Working Towards Watershed Management in the City of Atlanta

    In 2002, the leadership of the City of Atlanta kicked off a comprehensive program to have the cleanest urban streams and rivers in the country within a decade, recognizing that the City’s future economic growth, jobs, affordability, and quality of life all depend on clean water. Atlanta is faced with many obstacles on the way to meeting this challenge; a few of these include: Ongoing ...

  • Flow and high sediment yield from the Huangfuchuan watershed

    This study deals with general features of sediment transport in the Huangfuchuan river, an important branch river of the Yellow river, draining the Loess Plateau in China. The long-term precipitation records at 3 climate stations near the watershed have been used to assess the changes in precipitation in this region. By introducing metrics for runoff and sediment transport, long-term observations ...

  • Collaboration as process: a case study of Michigan's watershed permit

    Collaborative watershed management has been heavily promoted and widely implemented to address a variety of natural resource concerns, resulting in the adoption and adaptation of the approach to management by regulatory agencies. Although several characteristics or indicators of success for watershed partnerships have been identified in the literature, these often portray a direct cause and ...

  • City of Santa Monica Airport Watershed Management Plan

     ABSTRACT The City of Santa Monica implements best management practices (BMPs) to address urban stormwater runoff and uses a “hierarchy” of BMPs to prioritize implementation based on the principles of protecting public safety and the environment, maximizing environmental benefits, and minimizing costs. The hierarchy of BMPs includes the following (in order of priority): 1) harvesting, ...

  • Using watershed function as the leading indicator for water quality

    Diffuse nonpoint source (NPS) pollutants, such as sediment, nitrogen, phosphorus, and pathogens, have become the primary cause of water quality impairments in the United States of America. Resource management agencies in the USA are expanding the use of tools for the assessment of ecosystem function in water quality programs to control NPS pollution to meet US Clean Water Act objectives. ...

  • Office of wetlands, oceans and watersheds 2007 annual report

    OWOW is one of five offices in the Office of Water at EPA Headquarters in Washington, D.C. The office provides leadership, policy direction, and financial support to our 10 regional offices and to the states, tribes, and territories that implement our programs. We also work collaboratively with other federal agencies, as well as local governments, the private sector, and nonprofit organizations ...

  • Arundo Donax Removal in the Santa Ana River Watershed

    Orange County Water District (OCWD) was awarded the Ruth Anderson Wilson Award by the Santa Ana Watershed Project Authority for its collaborative efforts in a program to remove Arundo donax (arundo) from the Santa Ana River watershed. The arundo removal program is also one reason the U.S. Environmental Protection Agency selected OCWD as a Clean Water Partner for 2003. Arundo donax, or the giant ...

  • Hydroclimatic variability and change in the Chesapeake Bay Watershed

    The Chesapeake Bay (CB) Watershed is undergoing changes in climate, hydrology, and land use. The assessment of hydroclimatic impacts is important for both water quantity and quality management. This study evaluated the hydroclimatic changes using the Coupled Model Intercomparison Project 5 (CMIP5) data which provided statistically downscaled daily precipitation and temperature. An increase of ...

  • Misalignment of watershed and jurisdictional boundaries: the importance of scale

    The misalignment of the boundaries of watersheds and jurisdictions is cited often as a barrier to effective water governance, but the validity of the assertion depends on watershed scale and the decisions or processes involved. The paper probes these decision processes and their alignment with scales of natural watersheds and with governance processes. Two examples from the USA provide context ...

  • Arctic snow distribution patterns at the watershed scale

    Watershed-scale hydrologic models require good estimates of spatially distributed snow water equivalent (SWE) at winter's end. Snow on the ground in arctic environments is susceptible to significant wind redistribution, which results in heterogeneous snowpacks. The scarcity and quality of data collected by snow gauges provides a poor indicator of actual snowpack distribution. Snow ...

  • Integration of Watershed Planning and Wellhead Protection Programs

    For communities using groundwater as the primary source of water supply, delineating, managing, and protecting the wellhead recharge area is essential to assuring a sustainable water resource system. Because many communities are also required to obtain a National Pollutant Discharge Elimination System (NPDES) permit for discharges from municipal separate storm sewer systems (MS4s), delineating ...

  • Cryptosporidium source tracking in the potomac river watershed

    To better characterize Cryptosporidium in the Potomac River watershed, a PCR-based genotyping tool was used to analyze 64 base flow and 28 storm flow samples from five sites in the watershed. These sites included two water treatment plant intakes, as well as three upstream sites, each associated with a different type of land use. The uses, including urban wastewater, ...
