Classifying Natural Waters with the Forel-Ule Colour Index System: Results, Applications, Correlations and Crowdsourcing
Societal awareness of changes in the environment and climate has grown rapidly, and there is a need to engage citizens in gathering relevant scientific information to monitor environmental changes due to recognition that citizens are a potential source of critical information. The apparent colour of natural waters is one aspect of our aquatic environment that is easy to detect and an essential ...
متن کاملEvaluation and classification of trophic status in coastal waters of Homozgan province using trophic index Scale (Trixcs) and unscale (Untrixcs)
One of the most important issues in environmental management of coastal waters is the evaluation of Eutrophication. In this study, the trophic status of coastal waters of Hormozgan province was evaluated using Scale (TRIXCS) and Unscale (UNTRIXCS) trophic indices in 2012. The results showed that TRIXCS values were in the range of 3.6 to 5.9 (in the area 1 Mezo-Eutroph, areas 2 and 3 Mezotroph, ...

متن کاملSpectral analysis of the Forel-Ule ocean colour comparator scale
François Alphonse Forel (1890) and Willi Ule (1892) composed a colour comparator scale, with tints varying from indigo-blue to cola brown, to quantify the colour of natural waters, like seas, lakes and rivers. For each measurement, the observer compares the colour of the water above a submersed white disc (Secchi disc) with a hand-held scale of pre-defined colours. The scale can be well reprodu...
متن کاملassessment of the efficiency of s.p.g.c refineries using network dea
data envelopment analysis (dea) is a powerful tool for measuring relative efficiency of organizational units referred to as decision making units (dmus). in most cases dmus have network structures with internal linking activities. traditional dea models, however, consider dmus as black boxes with no regard to their linking activities and therefore do not provide decision makers with the reasons...
