The comparative analysis of the existing methods of assessment of a condition of ground deposits was made. On the basis of GIS ArcGIS for Desktop results of environmental control of ground deposits in east part of the water area of the Gulf of Finland are systematized, rated estimates and integrated characteristics in time and space are constructed. The analysis of the obtained data with the purpose...
South-to-North Water Transfer Project is the strategic move to implement the water resource allocation of China. The east line of the project is carrying out which would bring with it a lot of water environmental and ecological problems because of the wide range, long time and complex environment problems facing as well as some uncertainty the environment and ecology themselves have. In this paper,...
This paper has integrated the automatic monitoring system of water resources, and fully excavated the monitoring information contents, and introduced information fusion technology, and discussed and analyzed information collection and transmission and processing, and brought forward the system which has versatility and portability and scalability by using geographic information systems and databases...
Utilizing formats such as Geographic Information Systems (GIS) and Remote Sensing data assessment, an attempt was made to identify possible releasers of effluent waste into the major coastal watershed regions pertaining to ongoing research conducted within monitored mussel watch sites. The categorization of possible contaminating locations was made available through the development of a series of...
With the acceleration of urbanization, the phenomenon of urban drinking water pollution is quite obvious. According to China Environmental State Bulletin, the national surface water quality in general is moderately polluted in 2006. In the National Environmental Monitoring Network, the actual monitoring sections of the 745 surface water monitoring sections (the river sections 593, lake and reservoir...
Mangroves are small evergreen trees that flourish in the intertidal zones of river deltas, lagoons, estuaries, and coastal systems in the tropics, subtropics, and some temperate coasts. Mangroves provide a variety of ecological services for human beings, such as the protection of coasts from typhoon damage, pollutant absorption, and water purification. Guangdong province, used to locate half of mangrove...
Taking Second Songhua River as the study area, established the SQL Server-based spatial data warehouse. On this basis, using GIS, statistical data mining, visualized data mining and BP neural network to finish data preprocessing, build water quality assessment forecast model, and analyze spatial distributing of water quality. The results show that it is adapted to manage and analyze the spatial data...
With more and more serious problem on water pollution, it is significant to monitor the water quality and get to know the trend of the water quality change for water source management and water environment protection. Urban drinking water source quality monitoring system is based on GIS and remote sensing technology. This relatively integrated system comprises water source quality information receiving...
The Use of 3S techniques can provide a firm foundation for the dynamic monitoring and forecasting of water pollution and cause effective control of water environment, as it has no limit to space-time and region and can provide a timely, accurate and fast access to water pollution monitoring, so it will be a great revolution in utilization of water resources. The developed forecasting system is designed...
This paper reviews the progress of the application of RS and GIS integration technology and the design of integration system in water quality monitoring domain. Key aspects of available remote sensing techniques and the present application domain of water quality monitoring by remote sensing applications are briefly summarized. Special attention has been focused on the main principles of using remote...
Groundwater plays more and more important role in people's daily lives and social development in the study area for lack of surface water resources. So works of groundwater quality monitoring and assessment have great meaning to protect the public health. The geographic information system (GIS), as an analysis tool and visualization platform, is used to support data used, monitoring and groundwater...
Remote sensing has been used from the 80' s to study inland water quality. However, it was not until the beginning of the 21st century that MERIS started to acquire imagery with a very good temporal, radiometric and spectral resolution and with a low spatial resolution, which allowed to develop a reliable imagery acquisition system so as to consider remote sensing as an inland water management tool...
