Municipalities, regulatory agencies, and resource advocacy organizations are often tasked with the enormous responsibility of monitoring water quality and implementing management strategies for vast areas within their jurisdictions. A potential means for addressing the resulting sampling shortfall is the use of volunteer monitoring programs. The project reported herein demonstrates the use of Q...

We present a comprehensive critical review of well-established satellite remote sensing water indices and offer novel, robust Augmented Normalized Difference Water Index (ANDWI). ANDWI employs an expanded set spectral bands, RGB, NIR, SWIR1-2, to maximize the contrast between non-water pixels. Further, we implement dynamic thresholding method, Otsu algorithm, enhance ANDWI's performance. Applie...

AIM To describe waters monitoring in Croatia and legislation status for their evaluation, and to present health-relevant data and long-term analysis of the Drava river water, which is used in drinking water production. METHODS Survey of databanks of various Croatian institutions related to waters, and physical and chemical analysis of 13 surface water pollutants, applying HRN ISO laboratory m...

For more than 50 years, scientific insights from surface water monitoring have supported Swedish evidence-based environmental management. Efforts to understand and control eutrophication in the 1960s led to construction of wastewater treatment plants with phosphorus retention, while acid rain research in the 1970s contributed to international legislation curbing emissions. By the 1990s, long-ti...

The objective of this study is to optimize the river monitoring network in Taizihe River, Northeast China. The situation of the network and water characteristics were studied in this work. During this study, water samples were collected once a month during January 2009 - December 2010 from seventeen sites. Futhermore, the 16 monitoring indexes were analyzed in the field and laboratory. The pH v...

The issues of possible improvements, increased efficiency and/or optimization of monitoring systems in general, and monitoring designs, in particular, attract the attention of researchers for years. Application of formal techniques for these purposes looks appealing since it may validate suggested procedures or justify expenses required for data collection. The paper describes an approach to th...

Water quality directly influences individual and public health. Monitoring of water supplies and their sanitation is of paramount importance. The present study aimed to determine the concentrations of fluoride, chlorine, potassium, sodium, and trihalomethanes in the drinking water of five major universities in Iran. This descriptive study was conducted during January 2016-2017. In total, 60 sam...
