  • Application of the Most Recent Monitoring Systems in Hydro Power Plants

    Abstract The paper describes main reasons for refurbishment of hydro power plants and summarizes the most frequent works during refurbishment. A special attention is paid to the process of refurbishment of the electric equipment, in the first line generators and excitation systems, and integration of the most contemporary monitoring system. The paper talks about some of the methods of ...

  • Estimation and monitoring non-point source pollutant loads: an object-oriented hydro-information approach

    Numerous hydrologic/water quality models of run-off and soil erosion have been coupled to Geographical Information System (GIS) to determine Non-Point Source (NPS) pollutants from watersheds. Hydrology and water-resource engineering rely on observations of environmental conditions and the accuracy of environmental data. This paper focuses on estimation and monitoring of NPS pollutant loads based ...

  • Hydro-ecological effects of changing Arctic river and lake ice covers: a review

    Freshwater ice is an integral part of the hydrologic regimes of cold environments. It controls the ecology of related aquatic systems and is important economically, through the facilitation of winter transport and via generation of extreme hydrologic events. Given projected changes in future climate, concern has been raised about related changes in freshwater ice. This paper reviews the status ...

  • Generating Ecological Gains from Hydro-Electric Power - Case Study

    NCC has worked with Eskom to mitigate the environmental impacts of the Ingula Pumped Storage Scheme on a sensitive wetland site in the Little Drakensberg/Escarpment, including creating and managing a new conservation area. South Africa’s energy demand is growing at rates of around 5% a year, placing enormous pressure on Eskom not only to create new generating capacity, but also to manage ...

  • Summertime conditions of a muddy estuarine environment: the EsCoSed project contribution

    As part of the Estuarine Cohesive Sediments (EsCoSed) project, a field experiment was performed in a highly engineered environment, acting as a natural laboratory, to study the physico-chemical properties of estuarine sediments and the associated hydro-morphodynamics during different seasons. The present contribution focuses on the results obtained from the summertime monitoring of the most ...

  • Scottish Water Flow Monitoring Contracts

    Scottish Water commissioned HL in 2007 to deliver two separate flow monitoring contracts to help improve the water companies understanding of the yield and low flow conditions at several water supply catchments across Scotland. One project involved the installation of reservoir level, inflow flow gauges and recording raingauge devices in nine reservoir catchments in South West Scotland. Although ...

  • Field testing of a novel concept for automated on-line monitoring of β-D-glucuronidase activity in water resources

    Background and aim of research Direct determination of ectocellular ß-D-glucuronidase activity (GLUC) has been demonstrated as a potential, cultivation-independent, alternative method for the detection of faecal pollution in different water resources (Fiksdal 2008). Here a novel concept for an automated device capable of measuring the GLUC, after filtration of defined volumes of water, ...

  • Real-time forecasting of Hong Kong beach water quality by 3D deterministic modelling

    Bathing beaches are important marine resources for many coastal cities. To safeguard the health of beach users, beach management authorities in Hong Kong rely on the use of the concentration of the indicator bacteria Escherichia coli (E. coli). Currently, the beach water quality grading system (from “good” to “very poor”) is based on the geometric mean of the most recent ...

  • Differential behaviour of Escherichia coli and Campylobacter spp. in a stream draining dairy pasture

    The faecal indicator bacterium Escherichia coli and thermotolerant Campylobacter spp., which are potentially pathogenic, were investigated in the Toenepi Stream draining a pastoral catchment dominated by dairying. Bacteria concentrations were monitored routinely at fortnightly intervals over 12 months and intensively during storm events to compare the transport dynamics of ...

  • 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 ...
