Calculating a Water Poverty Index

World Development, 2002
Summary. — This paper provides discussion of ways in which an interdisciplinary approach can be taken to produce an integrated assessment of water stress and scarcity, linking physical estimates of water availability with socioeconomic variables that reflect poverty, i.e., a Water Poverty Index.

Indexing water rates

Journal AWWA, 1983
Indexing would allow water rates to move up or down in response to changes in the cost of providing service. Although indexing techniques have not been applied to water rates, they are used in the electric utility industry and could provide a method of generating adequate water revenues, particularly during periods of inflation.

Elaboration of a water ichtyologic potential index

Science of The Total Environment, 1992
A model has been developed, using physico-chemical data, in order to quantify the quality of surface waters and their ichtyologic potential: the WIPI model (Water Ichtyologic Potential Index). Many physico-chemical parameters, useless if considered individually, can be of practical interest for pisciculture (e.g., an explanation of systematic fish ...

The Temperature Coefficient of the Refractive Index of Water*

Journal of the Optical Society of America, 1948
A Jamin interferometer was used to measure the thermal coefficient of the refractive index of water for sodium light (λ=5893A) from −5°C to +25°C. From this was calculated the index-temperature curve over the same range. The results agree with those found by the Bureau of Standards for water within the experimental error, which is between 1×10−6 and 2 ...

Stochastic water quality index

Environmental Technology Letters, 1982
Abstract A Stochastic Water Quality Index (SWQI) is proposed and its use in assessing water quality in the Linggi River in Malaysia is shown. The SWQI provides for the first time an approach for developing an index which incorporates the probabilistic water quality entities.

Water Quality Index (WQI)

2020
In this chapter, we discuss the formulation of WQI that have been used by DOE, Malaysia to measure the quality of the river as well as drinking water in Malaysia. We begin with the elaboration on all six parameters that will used in the formulation later.

Consumers Water Quality Index

Journal of the Environmental Engineering Division, 1974
A water quality index based on physical, chemical, and biological parameters is proposed. The index is based on a geometric mean of transformed values of the parameters with a range of zero to one. The parameters of concern are temperature, nutrients, suspended solids, turbidity, coliform bacteria, dissolved oxygen, color, pH, grease, odor, and ...
