Abstract- An attempt has been made to develop water quality index (WQI), using Five water quality parameters pH,
Nitrates, Chloride, electrical conductivity and fluoride measured at 137 different locations in the study area rating scale is
developed based on FAO standards. It was found that 133 samples have the water quality index less than 150 and 4
samples have water quality index between 150-300. By spatial variation of WQI it can be found that 97.08 percent of the
water in the area is excellently suitable for irrigation.
Keywords: Chloride, Electrical Conductivity, Fluoride, Irrigation, pH, WQI.
I. INTRODUCTION
The Cauvery river enters Tamil Nadu at Hognekal of
Dharmapuri district from the west and takes a southern
course from Mettur and again takes south-eastern course at
Erode and then flows to Bay of Bengal flowing through
Trichirapalli, Thanjavur and Cuddalore districts. The
study area forms part of Cauvery basin, which lies on left
banks of Cauvery river. Lakshmantirtha river is a major
tributary to river Cauvery and has its originates in
Brahmagiri Devasi Hills of Western Ghats in southern
Kodagu district and flows through a distance of about 130
km. It enters the Mysore district near Chikkahejjur, south
west of Konana Hosahalli in Hunsur taluk and flows
through Hangodu, Hunsur and Kattemalavadi before its
confluence with Cauvery on the right side at Sagarkatte in
Krishnarajanagar taluk.
Water Quality Index allows for a general analysis of water
quality on many levels that affect a stream’s ability to host
life and whether the overall quality of water bodies poses a
potential threat to various uses of water. Relevant studies
on water quality index (WQI) and its modeling were
reviewed. WQI is valuable and unique rating to depict the
overall water quality status in a single term that is helpful
for the selection of appropriate treatment technique to
meet the concerned issues. .Water quality indices are tools
to determine conditions of water quality. Creating the WQI
involves three main steps (1) obtain measurements on
individual water quality indicators (2) transform
measurements into ‘‘subindex’’ values to represent them
on a common scale (3) aggregate the individual subindex
values into an overall WQI value.
II. MATERIALS AND METHODS
2.1 Study Area
The study area geographically lies between 750
29’ 19” E
and 760
37’ 40” E longitude and 110
55’ 54” N and
130
23’ 12.8” N latitude, as shown in Fig 1, and it covers
an area of 10874.65 Sq km. The maximum length and
width of the study area is approximately equal to 143.73
km and 96.75 km respectively. The maximum and
minimum elevation of the basin is 1867 m and 714 m
above MSL, respectively. The study area covers five
district of Karnataka state i.e., Chikmangalur, Hassan,
Kodagu, Mandya and Mysore as shown in Fig 2. There
are 137 sample location named as S1, S2 upto S137 as
shown in Table 3 the water parameters such as pH , EC,
Cl, NO3 and F are considered for estimation of irrigation
water quality index.

2.2 Methodology
WQI was determined following three steps. In the first
step, weight was assigned to each parameter (w) according
to its relative importance in the overall quality of water for
irrigation purposes from the FAO standards. Weights of 5,
4, 3, 2 and 1 are assigned to the quality parameters when
0-20, 21-40, 41-60, 61-80 and 81-100 % of samples are
within the permissible limit respectively (Raychaudhuri et
al 2014). The maximum weight of 5 has been assigned to
the parameters with 80 % or more than 80 % of the
samples are beyond the permissible limit. The pH, chloride
is given the minimum weight of 1 as >= 80 % of the
samples are within the permissible limit and of no harm
for irrigation use. % of the samples for the remaining
parameters are EC, F and NO3 are 36.4, 85.8, and 72 %
respectively hence these are assigned weight of 4,1 and 2
respectively. The second step was followed and relative
weight was assigned accordingly .The relatives weights of
the each parameters are given in the Table 2 .The third
step, a quality rating scale (qi) for each parameter is
assigned and then WQI is developed for each water
samples

IV. CONCLUSIONS
In the present study the water quality parameters considered
shows that almost 95 percent are with in the FAO standards
for irrigation. 133 samples of 137 shows class I index
Excellent suitable for irrigation 4 samples shows class II
index . By spatial variation of WQI it can be found that
almost all the portion of the water is suitable for irrigation
with 97 percent of the area is excellently suitable.
