In mountains, springs and seepages are the main sources of drinking water. The
shortage of drinking water arises mainly due to drastic reduction in spring
discharge during summer. The inhabitants are compelled to collect potable water
from far off distances, reduce water consumption, consume unhygienic water and
face social conflicts. Keeping it in view, two perennial natural springs of
Uttarakhand, viz., 'Hill Campus Spring (HCS)' and 'Fakua Spring (FS)' were
selected for the study with the objective to develop dynamic models for prediction
of their discharge. The daily spring discharge data collected from 1999 to 2001
was used for formulation and calibration, and validation of the models was done
with discharge data of 2002. The maximum and minimum discharge of HCS and
FS varied from 30 lpm to 4.70 lpm and 80 lpm to 1.20 lpm, respectively. Efforts
were made to develop generalized models such as annual, monsoon and nonmonsoon,
which are capable to address the variability in discharge owing to erratic
behaviour of monsoon and non-monsoon rains. Time variant linear dynamic
models for monsoon season were found to be more suitable models having more
Coefficient of Multiple Determination (CMD) values (94.18% and 92.11% for
HCS and FS, respectively) than annual models (87.28% and 90.48% for HCS and
FS, respectively) to predict the daily spring discharge of monsoon months for both
springs. Thus monsoon season model could be recommended for extensive
application for prediction of discharge of monsoon months.
