Monitoring, environmental emergencies management and water treatment improvement of freshwater lakes in China: the Chao Lake case study

Severe eutrophication of freshwater lakes, with the subsequent risk of algal blooms, has a critical effect on the safety of drinking water supplies in China and is one of the main environmental emergencies in the country. This paper focuses on Chao Lake, a large, shallow eutrophic lake used as a source of drinking water. The study considers the possibilities of improving the lake monitoring ...

Monitoring of regional lake water clarity using Landsat imagery

The application of remote sensing technology to water quality monitoring has special significance for lake management at regional scale. Water clarity expressed in terms of Secchi disk transparency (SDT) is a highly useful indicator of trophic status and ecosystem health. In this study, we related Landsat TM and ETM+ data with ground observations to develop a model for the estimation of SDT ...

Application of dynamic threshold in sea and lake ice mapping and monitoring

Ice detection and monitoring algorithms using visible and infrared images are generally founded on thresholds-based approaches. Classification of features over ice covered sea requires a series of reliable thresholds. The change in surface conditions throughout the season affects these thresholds and makes their adjustment necessary. This study proposes an operational method based on a set of ...

Air monitoring of persistent organic pollutants in the Great Lakes: IADN vs. AEOLOS

When designing a monitoring campaign, one has to consider many factors in the decision to perform a long-term synoptic monitoring program or a short-term intensive study. Each has its own advantages and disadvantages. This paper compares and contrasts the information obtained from two studies conducted on the Laurentian Great Lakes. One, the Integrated Atmospheric Deposition Network (IADN), is a ...

Case study - Water quality monitoring and weather data at Pampulha Lake-Brasil

In 2010, OTT Hydromet's partner in Brasil, Hexis began working with CETEC. This resulted in the installation of a buoy, equipped with an automatic profiling system, in early 2013. The project’s objective is the continuous monitoring of the lake’s water quality, with focus on improving this by the 2014 World Cup Games. Adcon, Lufft and OTT technologies (Hydrolab DS5X ...

The Great Lakes, an Ecosystem Rehabilitated, But Still Under Threat

Since 1972, the Parties (United States and Canada, 1987) to the Great Lakes Water Quality Agreement have been working collaboratively to achieve the purpose of the Agreement “to restore and maintain the chemical, physical and biological integrity of the waters of the Great Lakes Basin Ecosystem”. Billions of dollars and countless person – hours have been expended towards this end, but have the ...

Global study of lakes enhances understanding of hydrological cycle

We now have much more robust data available on the amount of water in lakes worldwide thanks to a comprehensive database created by researchers at McGill University in Montreal. The McGill scientists discovered the total shoreline of the world’s lakes is more than four times longer than the global ocean coastline. At 7 million kilometers, this is 10 times the distance from the Earth to the ...

Strategies for Managing the Lakes of the Rotorua District, New Zealand

The Rotorua district in New Zealand contains 12 nationally important lakes. Environment Bay of Plenty (EBOP), which has the responsibility of managing the quality of these lakes, set a routine monitoring program for these lakes and adopted the method of Burns et al. (1999, 2000) to analyse the data and calculate a numeric Trophic Level Index (TLI) value for each. In 1994, the district community ...

Remote sensing models using Landsat satellite data to monitor algal blooms in Lake Champlain

Lake Champlain is significantly impaired by excess phosphorus loading, requiring frequent lake-wide monitoring for eutrophic conditions and algal blooms. Satellite remote sensing provides regular, synoptic coverage of algal production over large areas with better spatial and temporal resolution compared with in situ monitoring. This study developed two algal production models using Landsat ...

Lake Edku water-quality monitoring, analysis and management model for optimising drainage water treatment using a genetic algorithm

Lake Edku, one of the northern Nile Delta Lakes, subjected to huge inputs of nutrients (especially phosphorous and nitrogen). These nutritional conditions create rich resource spectrum for algal growth and make the lake suffer from high level of eutrophication. Lake Edku does not have numeric water quality criteria for nutrients. The main objective of this research is to develop a model which can ...
