Research and investigation was carried out on “Assessing the impacts of climate change on
Surface Water Resources of Dal Catchment”. Two catchments of Dal Lake viz. Dachigam
and Telbal were selected for the study purpose; since the two alone contribute about 80%
to the waters of Dal Lake. The stream discharges and climatic data were obtained for the
previous 20 years. The three main variables of study were discharge, temperature and
precipitation; discharge being the response variable with respect to the remaining two.
Trend lines were established for each of the variables with the help of the 5 year moving
averages; which revealed the increasing trend in the temperature and the stream discharge,
while a decreasing trend was visible in the precipitation. The trend of the three parameters
was in accordance with the global climatic and hydrological findings. Further, to analyze
the findings, Mann-Kendal’s test was used to ascertain the results. As per this test,
discharge displays a significant trend over the given period of study at 5% significance
levels with a p-value of 0.006; temperature also indicates a significant trend at 10%
significance level with a p-value of 0.086 while the precipitation could not reveal any
significant trend over the limited time frame of study even at 10% significance level, which
could be a result of the seasonal dimension to it. The given study concluded that there was
an adverse effect of the climate change on the catchment of the Dal Lake.
