Monitoring chlorophyll-a concentration (Chl-a) in inland waters, particularly hypertrophic lake waters in megacities, is a critically important environmental issue. To enable long-term Chl-a monitoring using Landsat series sensors, development of a Chl-a estimation algorithm for the new Landsat sensor is requisite. This study aims to identify the most accurate algorithm for Chl-a estimation in hypertrophic...
Every year, the province of South Kivu in the Democratic Republic of Congo (DRC) is burdened by recurrent outbreaks of Cholera especially in the Fizi and Uvira regions. Although the root causes of the epidemic are the scarcity of clean water and quality hygienic latrines, human-induced malpractices are also contributing factors. Hence, providing clean water and hygienic latrines must be accompanied...
Poor water quality in Pettipalam Colony in Thalassery, Kannur District, Kerala is the source of many health issues among the colony residents. Soil and water contamination due to the accumulation of waste is another serious issue that adversely affects the health of the inhabitants in the area. There is a compelling need for the village inhabitants to appropriately monitor the water bodies and take...
Water is one of the precious factors in human life. It plays a vital role in the survival and existence of flora and fauna. But, now a days it is been exploited heavily by dumping of human waste, industrial and chemical waste in to the water bodies which is the resultant of water being contaminated with toxic chemicals. Water scarcity and water contamination has been one of the major issues faced...
The river pollution has become a prominently environmental problem to human survival. Thus it is in urgent demand for real-time monitoring of river water. However, traditional methods have some disadvantages such as complicated instrument, high cost and cumbersome operation. Herein, we developed wireless conductivity sensor, which forms a monitoring network system based on ZigBee. The node of the...
Efficient management of water resources is a growing global concern. In Brazil, most regions deal with problems related to high rates of water loss in distribution systems. This situation involves a complex environment with multiple decision-makers, several alternatives, and subjective variables. Therefore, its evaluations require interactivity, clarity, learning, and that plausible aspects be discerned...
Sensor networks have been widely used in environment monitoring. Although there are some related works about water pollution monitoring and water pollution source localization using sensor networks, there are many problems which have not been solved so far. In this paper, the current research status on water pollution monitoring and water pollution source localization in sensor networks is illustrated...
With the continuous progress of rural construction, the problem of rural drinking water pollution is increasingly prominent. In view of water pollution, a design of rural drinking water monitoring system based on wireless sensor networks is proposed that nodes take STM32 as the core chip and WLK01L39 as well as its peripheral circuits are used as wireless communication modules and Beidou S1216 is...
In order to solve the existing traditional rural drinking water monitoring in a lot of manpower, material resources, real-time, this paper introduces a WSN based on the rural drinking water source monitoring system design, the system consists of five parts: water quality monitoring, soil monitoring node node, node, routing node and gateway server. Water quality monitoring node, soil monitoring nodes...
This paper presents a water quality monitoring system using low power hardware based in the Internet of Things. Six sensor nodes for water quality monitoring in pisciculture are installed in three region of the Peruvian amazon. The sensor node is a modular hardware composed by control, communication and sensor module that measure parameters such as pH, conductivity and temperature. All data information...
The change of ecosystem and the surrounding atmosphere by different forms of pollutants (Chemicals and energies) are called environmental pollution. Pollution affects the climate most. The issue of environmental pollution and climate change has become an international concern due to their affects to the physical and biological entities of the environment. In this paper, the main objective is to find...
Freshwater monitoring is becoming an essential activity due to limited availability of drinking water and an increasing presence of various pollutants. Tons of toxic waste added to water sources everyday contributes to the decrease in the planet’s biodiversity and even an extinction of many species of animals and marine life. Many millions of birds perish each year due to waterway pollution...
The evaluation technology of water quality is of great significance for monitoring and management of surface water quality. In this paper, the Extreme Learning Machine algorithm was optimized with the Dolphin Swarm Algorithm. Optimal weight and threshold of Extreme Learning Machine algorithm was searched by the process of creating a virtual team and seeking the best position of Dolphin Swarm. Four...
The conventional method of testing water quality is to gather samples of water manually and send to the lab to test and analyze. This method is time consuming, wastage of man power, and not economical. The water quality measuring system that we have implemented checks the quality of water in real time through various sensors (one for each parameter: pH, conductivity, temperature) to measure the quality...
Algae bloom is an important manifestation of water pollution in lakes and rivers, its status evaluation is the premise of algae bloom treatment. Based on remote sensing image and multi-site water quality monitoring information, this paper introduces sensor priority and evidence credibility to realize the discount processing of evidence. And then, the evaluation model of algae bloom in lake and reservoir...
Water leakages in pipelines and water distribution systems are the major issues in many countries. In this paper, we propose an automatic water pipeline leak detection device to continuously monitor the water pipelines to reduce manpower involvement. This device not only reduces human resource but also the time used to process collected information. Our device allows leak detection staff to remotely...
The quality of water resources has a direct impact on the daily life of mankind and the sustainable development of society. However, with the rapid development of national industrialization, the current industrial wastewater discharge and improper handling have become more and more serious, especially for the growing domestic water pollution today, it is an urgent need for an efficient water quality...
The main objective of this paper is recirculating the water and prevents wastage of water. Recently, aqua industries are a water management system which is operating open loop type of water circulation. It means after utilizing the water, then the waste water will send out, in this case it will waste high quantity of water and spend more money for maintenance purpose. From that point of view we are...
With the problem of water pollution is more and more prominent, online measurement of various parameters has been a basic requirement for the sake of water quality protection. However, the online monitoring equipment is very expensive, which hampereds the scope and effect of monitoring. Thus, soft measurement technology in industrial sewage which using neural networks and data driven method can be...
Water bodies have seen a rise in chemical pollutants in recent years. Therefore quality testing has become an essential part of treatment. Currently in India, monitoring of water quality is done by physically going to water bodies and collecting samples which are then sent to be tested in laboratories. This is time consuming and inefficient method. To automate this process, water quality monitoring...
