Water is the source of human life. However, a large amount domestic sewage, industrial wastewater and agricultural produced in production life pollute surface water, threatening normal people.In order to grasp water quality fully, temperature, PH. turbidity conductivity sensors are adopted collect various parameters, necessary software hardware design on-line quality' monitoring system complete...

Based on water quality monitoring data of four inflow rivers of Nansihu Lake in 2006, 2007 and 2008, the water qualities were evaluated according to the method of comprehensive water quality identification index, with the indicators of dissolved oxygen, CODMn, biochemical oxygen demand and ammonia nitrogen. The results show that the rivers has been in the state of serious pollution, in which th...

Water quality monitoring and evaluation are important practices for water resources management. And the major concerns are remote and low-cost information transmission technology and accurate water quality evaluation strategy. Taking these concerns into consideration, a remote monitoring and evaluation system based on wireless sensor networks (WSN) and LS-SVM method was designed in this paper. ...
