  • Monitoring System for Hydrologic Evaluation of Landfill Covers

    Three test sections were constructed and instrumented to assess the hydrologic behavior of earthen final covers at two municipal solid waste landfills. A traditional design using a “resistive barrier” was used for two of the test sections, whereas an alternative design using a “capillary barrier” was used for the third test section. The test sections were built in two distinctly different ...

  • Data quality assessment in hydrological information systems

    The hydrological data fed to hydrological decision support systems might be untimely, incomplete, inconsistent or illogical due to network congestion, low performance of servers, instrument failures, human errors, etc. It is imperative to assess, monitor and even control the quality of hydrological data residing in or acquired from each link of a hydrological data supply chain. However, the ...

  • Nuclear energy from Dwight Eisenhower to Mohamed El Baradei

    At the start of the nuclear age, nuclear power was seen as a terrifying instrument of death. Nowadays, radiation sources, using either radioactive material or radiation generators, are widely used throughout the world in medicine, research, agriculture, industry, hydrology and education. The Nobel Peace Prize 2005 was awarded jointly to Mohamed El Baradei and the International Atomic Energy ...

  • Institutional arrangements for articulating land and water management in peri-urban catchment: example of the metropolitan region of Sao Paulo, Brazil

    The development of mega-cities exerts an increasing pressure on water resources in their peri-urban areas. Rapid changes in land use in these areas, characterised by the specific hydrologic functions they provide for the city, has resulted in increased pressures on water availability and quality. In the past, the traditional dual (urban/rural) focus of the institutions, their preference for ...

  • A review of Australian institutions for riparian adaptation to climate change

    Australia represents a global proving ground for effective riparian climate change adaptation due to its scale and diversity, extreme variation in runoff and degrees of aridity. An array of autonomous riparian zone (RZ) management adaptations have emerged in Australia that have captivated the international community but have yet to be effectively delivered. This paper reviews government ...

  • Stevens Hydra Probe Furthers Scientific Research at Alabama A&M

    For more than a decade now, the Stevens Hydra Probe has been an important data collection instrument used in The Soil Climate Analyses Network (SCAN). The SCAN Program helps scientists study soil moisture and temperature variability at different time scales and under different land uses and land covers. Studies that involve the SCAN program benefit the environmental science community as well as ...

  • Research and education - University of Illinois

    During the 2007-2008 academic year grants were awarded to Dr. Praveen Kumar and Dr. Art Schmidt in the Department of Civil Engineering at the University of Illinois, to implement a new data collection system on the Urbana campus. The goal of this project is the deployment of sensors to provide high-resolution, semi-realtime datasets for research and education. The resulting data is published in ...

  • EA Framework ADCP

    Hydro-Logic have lead the introduction of ADCP technology into UK hydrometric practice, and have been exclusive distributors in the UK and Ireland for Teledyne RDi ADCP instruments since 2002. Subsequently, the EA appointed Hydro-Logic to a National Framework Contract for the supply of ADCP equipment. Hydro-Logic have since sold hundreds of profilers for both current meter gauging and continuous ...

  • Online discharge measurement with OTT SLD

    Background For the economic management of the waterways between Elbe and Oder it is essential to know the discharge of these rivers at defined locks. The authority for water and navigation (WSA) in Lauenburg operates hydrological stations for the measurement of water level and discharge to effectively regulate the water flow at the locks in Plau and Malliß ...

  • OSU Researchers Deploy Stevens Equipment in Study of Green Infrastructure Treatment for Groundwater Runoff

    Stormwater runoff pollution is a serious issue that faces almost every urban and suburban environment. In older city infrastructure, runoff from roofs, parking lots, and streets flows directly into the sewer system and must be handled by the municipal wastewater treatment facility, increasing the amount of work the system must undertake. For the past 30 years, the infrastructure for stormwater ...

  • Discharge Measurements In Low Flow Conditions With ADC p t echnology – First Experiences In Nepal

    Low flows prevail during about nine months of the year in Himalayan rivers as a result of the influence of the monsoon climate. They account for a large portion of the annual water balance and accurate information about these flows is therefore critical for water resources planning, development, management and hydropower design. Issues that occur with the neighbouring country India are often ...

  • Optical Assessment of Dissolved Organic Carbon

    Natural organic matter is present in all sources of drinking water. When chlorine is used for drinking-water treatment, a portion of the natural organic matter reacts to form halogenated compounds, referred to as disinfection by-products (DBPs), some of which are regulated by the USEPA due to their health effects. The implementation of stricter drinking-water quality regulations for DBPs has ...
