Many studies deal with water quality evaluation using remotely sensed data. In the field of remote sensing, there have been proposed several procedures how to observe selected parameters of water qual...
This paper presents the first results of a study which investigates river basin water quality management based on the ability of GIS to integrate different data sources into a common geographical data...
A study was conducted in Hong Kong with the aim of deriving algorithms for the retrieval of turbidity, chlorophyII a and suspended solids concentrations from Terra/MODIS 500m level 1B reflectance data...
In this paper, the one-dimension river quality system dynamics model was applied to the water quality simulation, and the conceptual GIS-SD frame was constructed. Based on the component GIS and system...
Lake Urmia, the second hyperaline lake in the world, because of its climatic and? economical importance has燾reated燼 populated region in Iran, and爄n爎eturn its fragile ecosystem? has?been affected by...
For the purposes of our study, an ASTER satellite image was used, acquired on 5 October, 2001, with 14 spectral bands resampled at the spatial resolution of 15 m. The study area concerns the geograph...
Lakes are important environmental, economic and recreational resources and contribute significantly to the quality of life in Minnesota. However, because of expense and time requirements for monitor...
With the rapid development of the regional economy, water pollution has gradually become an environmental problem that cannot be ignored. As an important water source in central China, the Han River...
Spatial variations in ground water quality in the Khartoum state, Sudan, have been studied using geographic information system (GIS) and remote sensing technique. Gegraphical informtion system a too...
Optical imaging techniques can be used to produce maps of concentrations of chlorophyll-a, total suspended matter and coloured dissolved organic carbon. The Rijkswaterstaat sets up a production chain...
The state of Andhra Pradesh, India falls in water stress4 area. The primary objective of this study is to examine the spatial distribution of different chemical elements with respect to its contaminat...
Solving of several global and regional problems requires adequate data about lake water quality parameters like the amount and type of phytoplankton dominating in the lakes, the amount of dissolved an...
Presently, planning and assessment in maintenance, renewal and decision-making for watershed hydrology, water resource management and water quality assessment are evolving toward complex, spatially ...
