A Monte Carlo-CWQImodel was established to predict the comprehensive pollution level of the river, two organic pollution indicators, ∑PAHs and ∑n-Alks were incorporate intoCWQI, and the weight of each pollution indicator in the comprehensive pollution assessment was analyzed bySRCCanalysis. The es...
Physical water scarcity metrics for monitoring progress towards SDG target 6.4: an evaluation of indicator 6.4.2 “level of water stress” Sci. Total Environ., 613–614 (February) (2018), pp. 218-232, 10.1016/j.scitotenv.2017.09.056 The Authors View PDFView articleGoogle Scholar Vázquez-Row...
To monitor progress towards this target, two indicators are used: Indicator 6.4.1 measuring water use efficiency and 6.4.2 measuring the level of water stress (WS). This paper aims to identify whether the currently proposed indicator 6.4.2 considers the different elements that need to be ...
2017). BE is used here simply as an indicator of aquifer conditions (e.g., unconfined versus confined) and to consider potential poroelastic responses in measured groundwater levels. Statistical clustering of national groundwater-level observations The representivity of observations at Bhuapur and ...
According to the data of different indicators in each region in Table S8, the weight of each indicator obtained by entropy weight method are shown in column 6 of Table 4. It has been seen that most of the index weights are close, but some of them are quite different with comparing the ...
