  • A simple numerical method for snowmelt simulation based on the equation of heat energy

    This paper presents one-dimensional numerical model for snowmelt/accumulation simulations, based on the equation of heat energy. It is assumed that the snow column is homogeneous at the current time step; however, its characteristics such as snow density and thermal conductivity are treated as functions of time. The equation of heat energy for snow column is solved using the implicit finite ...

  • 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 ...

  • 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 ...

  • Pocket Gauger

    Hydro-Logic recently received major orders for the Pocket Gauger Windows Mobile software package from the two environmental regulators covering England and Wales (EA) and Scotland (SEPA). These orders have effectively confirmed Pocket Gauger's status as the UK's de-facto industry-standard system for collecting current-meter gaugings using conventional impellor-style meters. Pocket Gauger acts as ...

  • H-ADCP Flow Gauge Installation

    Wessex Water contracted HL to install a new flow-gauge to provide flow data on the environmental impact of abstraction upstream and downstream of a riverside borehole for public-supply. Due to the channel and hydraulic conditions at the site on the River Yeo in Somerset, HL selected a horizontal ADCP Channelmaster device from Teledyne RDi for providing accurate velocity profiles at one elevation ...

  • Wetlands of International Importance in Russia

    The Convention on Wetlands of International Importance especially as Waterfowl Habitat was adopted on the 2nd February 1971 in the Iranian city of Ramsar. Thus, it has come to be popularly known as the “Ramsar Convention”, and the 2nd of February each year is celebrated as World Wetlands Day. Wetlands are areas where water is the primary factor controlling the environment and the ...

  • Who Owns Groundwater?

    California’s drought underscores the need to improve how the state - and the rest of us - divvy up a resource in demand. Grapevines march across wires strung along rolling hills, their little trunks improbably supporting heavy black fruit. Cindy Steinbeck’s family has been farming this land since 1920. They grow Zinfandel, Viognier, Cabernet, Merlot, and Petite Syrah grapes but are ...

  • Sea Level Rise: Risk and Resilience in Coastal Cities

    Introduction One of the most dire impacts of anthropogenic climate change is a rise in the global sea level caused by the melting of glaciers and land-based ice caps, as well as a smaller increase from expansion due to the higher temperature of the water itself.  Unlike some other predicted effects of climate change, this impact has already been observed for some time.  Indeed, ...

  • Closures of mine a new challenge for Romania

    AbstractThe mining activity is one of the oldest activity in Romania, dating from the year 100 B.C. The gold and silver ores represented one of the riches of our country. In time the economic content of metals diminuend, and the ore mines become non profitable. Due to this situation the best option of the State was the closure and ecological rehabilitation of the mines.The steps for the ...
