  • 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, ...

  • Evaluating the success of phosphorus management from field to watershed

    Received for publication January 30, 2008. Studies have demonstrated some P loss reduction following implementation of remedial strategies at field scales. However, there has been little coordinated evaluation of best management practices (BMPs) on a watershed scale to show where, when, and which work most effectively. Thus, it is still difficult to answer with a degree of certainty, critical ...

  • Applying Integrated Watershed Management Techniques in Stevens Creek

    ABSTRACTThe Stevens Creek Watershed located just east of Lincoln, Nebraska, will experience rapid growth pressures in the coming years, a trend that has the potential to adversely impact the region’s natural resources. To maintain a balance of economic growth opportunities and the protection of natural resources, the City of Lincoln and the Lower Platte South Natural Resource District embarked on ...

  • Senix Water Level Sensors Drive Irrigation Automation Project

    Australia’s Water Crisis Irrigation management is serious business in Australia especially within the Murray-Darling Basin, a 1,000,000 square kilometer watershed that is home to Australia’s most productive agricultural land. The basin’s 23 rivers have ...

  • 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 ...

  • Managing the NYC Watershed WWTP Upgrade Program- “Re-tooling an Entire Watershed’s Wastewater Treatment Infrastructure”

    New York City has the largest unfiltered surface water supply in the world. Within the 1,969 square miles tributary to the system's 19 reservoirs and three controlled lakes, are 106 non-City-owned permitted wastewater treatment plants, owned by a wide variety of private, public and municipal organizations. In order to avoid filtration of their 1.3 Billion gallon per day supply, New York City ...

  • 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 ...

  • Preliminary identification of watershed management strategies for the Houjing river in Taiwan

    The Houjing River watershed is one of the three major river watersheds in the Kaohsiung City, Taiwan. Based on the recent water quality analysis, the Houjing River is heavily polluted. Both point and non-point source (NPS) pollutants are the major causes of the poor water quality in the Houjing River. Investigation results demonstrate that the main point pollution sources included municipal, ...

  • Feasibility of rural regeneration by cooperative watershed resources management in Japan

    This study addresses multiple social issues in order to regenerate collapsing rural regions and realise environmentally friendly economic growth from a standpoint of watershed-based management. It is difficult for a single agricultural community to revitalise itself and therefore, such a community needs to seek cooperative management involving other regions and industrial sectors. In this case ...

  • Drought indices supporting drought management in transboundary watersheds subject to climate alterations

    There is growing concern in Iraq about the inefficiency of reactive drought management practices. Corresponding actions are largely characterized as emergency-based responses that treat the symptoms of drought rather than consider the vulnerability components associated with impacts. The Diyala watershed shared between Iraq and Iran has been used as an example transboundary river basin marked ...

  • Integrated water resources assessment and management in a small watershed – a geomorphic approach

    Depleting water resources and increasing human demands on the available fresh water resources suggest the need and scope for integrated water resources assessment and management. Narava basin, a small watershed spread over 105 km2 with a khondalitic suite of rocks and gneisses of Archaean age in the north coastal region of Andhra Pradesh, India was studied to propose effective water resources ...

  • SWAT meta-modeling as support of the management scenario analysis in large watersheds

    In the last two decades, numerous models and modeling techniques have been developed to simulate nonpoint source pollution effects. Most models simulate the hydrological, chemical, and physical processes involved in the entrainment and transport of sediment, nutrients, and pesticides. Very often these models require a distributed modeling approach and are limited in scope by the requirement of ...

  • Balancing Wetland Regulation with Stormwater Management on a Watershed-Wide Basis: A Case Study.

    Maryland reconciles rapid growth, water-quality goals, and habitat protection. In response to increasing regulatory authority over its water resources, the Maryland Department of the Environment (MDE) has combined various programs and processes into a 'one-stop shop' where various issues can be addressed in a uniform and consistent manner. As part of this process, onsite conditions are assessed, ...

  • Watershed-level analysis of exceedance frequencies for different management strategies

    Exceedance of water-quality standards is important in assessing water quality. The effectiveness of soil conservation Beneficial Management Practices (BMPs) should be measured according to the BMPs' impact on exceedance frequencies. However, estimating exceedance frequencies for different management scenarios with field measurements is practically impossible due to difficulties in obtaining ...

  • 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. ...
