The following paper describes the design, implementation and preliminary tests of an Unmanned Surface Vessel (USV) robot, able to collect water quality parameters and bathymeter measurements in lakes and bodies of fresh water at the Peruvian highlands. The USV robot is developed in order to be a measurement tool to monitor water pollution and help to improve the current methods used for this task...
Rapid determination on the microbial count in water will be a useful index to evaluate its safety for daily activities. This study proposes a rapid method to evaluate total microbial count for river water by using the concentration of the volatile organic compounds (VOCs) formed on the headspace as indicator. Water sample was first filtered through a 0.22 micron filter, which liter the filter was...
The water quality analysis is important for human health and environmental protection. There are many physical and chemical methods for such analysis, with different accuracies, complexity and time consumption. In the presented paper, a colorimetric method, based on virtual instrumentation is suggested and considered in details. At the end of the paper, the concentration of free chlorine in water...
Water quality may differ in at least two physical parameters from water system typically used to measure the growth of microbes: pH and temperature. This study is to determine the most significant water physical parameters associated with the growth of Escherichia coli (E. coli) strain in the laboratory. Water physical parameter in distilled water with cultures strain in nutrient broth were performed...
Protection of the natural water resources becomes more and more important issue. Usual way to deal with this problem is to build on-site monitoring station capable for independent measurement of water quality parameters where all the measurement equipment is installed and where all measurements are done. But, in this case a dedicated person is needed which on regular basis will collect the data from...
The development of a surface water monitoring network is a critical element in the assessment and protection of water quality. We developed a prototype of easy to install technology by which the different surface water (e.g. rivers, lakes) quality indicators can be measured. The project pilot area is the Sajó river with 5 monitoring station. Thanks to the modular design of the sensor-tube, the equipment...
Following the implementation rules of EU INSPIRE Directive, we designed and developed a system for pollution detection for Somes River. We address the challenge of providing public information about water quality parameters measured by wireless sensor networks placed on the river bed and river shore. The system provides pollution alerts based on the analysis made on the monitored water parameters...
Reflectance ratios are widely used in the water quality retrieval algorithms, but they are not universally applicable and have to be tuned to the local conditions. In this study we present optical characteristics of the River Sava and assess two band ratio model for the prediction of concentrations of Chl-a from the hyperspectral data. We found that the best correlation was with the NIR-blue band...
Remote sensing has been used to understand water distribution and pollution in recent years. In this study, water quality conditions were analyzed using the data collected by the Advanced Visible and Near Infrared Radiometer type-2 (AVNIR-2) of the Advanced Land Observing Satellite (ALOS). The method comprised three steps. First, the AVNIR-2 data was preprocessed using geometric correction and mask...
A comprehensive evaluation model of water quality based on Fuzzy Complex Index Method was analyzed. Based on the data and its characteristics of the sewage treatment plant outlet water in Foshan, the polluting factors which have a greater polluting impact to assess the water quality were ascertained, and the membership functions and fuzzy matrix were established, finally the outlet water quality of...
The GCC (Gulf Cooperation Council) countries lack adequate freshwater availability. Hence, most of the fresh water is obtained from seawater desalination. Because seawater is the main source of fresh water and can be polluted by human and non human activities, it needs to be continuously protected and monitored. The objective of this paper is to highlight the development of an automated approach for...
As the main portion of urban catchment, road is also a major non-point pollution source of receiving water body. The road runoff pollution has attracted wide attention. The paper makes a study on six rainfall road runoff from 3 different types of roads, analyses the status of road runoff pollution, the surface runoff pollution load and correlation between road runoff pollutants. The result shows that...
This paper presents a numerical method to simulate the 2D tidal flow and water quality under the orthogonal curvilinear coordinates. In order to overcome the computational difficulties in natural rivers, such as the complicated boundary figures, the great disparity between length and width of computational domain, etc., orthogonal boundary-fitted grid is used, the irregular domain in physical plane...
This paper researches on water quality condition of WenYu River basin in Beijing. According to stationing principle and field investigation, the whole basin is divided as 22 monitoring sections and 10 pollution indicators. By means of SPSS soft applied in principal component analysis method, paper analysis on the main pollution indicators and the main pollution contribution sections. The result shows...
The application of Fuzzy Multi Criteria Decision Making (FMCDM) with case studies for ranking the industries, the paper presents the multifaceted formalism along with Type 1 Fuzzy logic Inference System (Type 1 FLS) for fuzzily describing river water quality for bathing. It is the belief that the Computing With Words (CWW) methodology with focus on fuzzy logic will be of practical utility in addressing...
In this paper, the measured date of air environment quality, water environment quality, acoustic environment quality and solid wastes in the Kanas National Natural Heritage Site of China during different periods were compared, the main factors resulting in the tourist environment pollution were evaluated, and corresponding ecological design approach for controlling tourist environment pollution was...
Animals are known to alter their behavior in response to changes in their environments. Therefore, automatic visual monitoring of animal behavior is currently of great interest because of its many applications. In this paper, a video-based system is proposed for analyzing the swimming patterns of fishes so that the presence of toxic in the water can be inferred. This problem is challenging, among...
The testing layout sample points to collect the water measured spectral data with taking University of Technology section of Chengdu Dongfeng Drain as the research object; This research analyzed measured spectral curve combining with transforming spectral curve to infer the water pollution features of the yellow substance in the life affected zone; And it also inferred the water pollution chemical...
This paper focuses on piecewise linear growth model of water quality about the river. The experiment was performed on South Sewage Discharge River of a certain Coastal City, in China. Physical, chemical parameters such as water temperature (T), turbidity (Tur) were measured over a one-year period including dry period, level period (May), wet period, level period (Oct.). Based on multilevel models,...
To investigate the characteristics of migration and distribution of phenanthrine plays an important role in the control of polynuclear aromatic hydrocarbons (PAHs) contamination. This experiment simulate the migration and distribution of phenanthrine in soil-groundwater by using indoor dynamic soil column test and hydrogeological theories so as to understand the condition and rules of phenanthrine...
