Water plays same role to earth as oxygen to body. In order to safe this Globe from droughts
and floods, it is essential to design a strategy for the balanced usage of water resources for urban uses and
agriculture. For such purpose, Precipitation regions were recognized in river Indus basin in Pakistan by
examining the rainfall frequencies with the help of global wavelet power spectra. Records from 52 rain gauges
were studied and the outcomes of the whole power spectra exhibited a low annual frequency all over the
basin; whereas additional frequencies are present with major significance that indicate changes in the rainfall
system. While, the calculated global wavelet power spectra showed variable frequencies, they presentedodd
patterns (symbolized by A and B) that might be used to portray the region. Therefore, three sub-regions with
consistentprecipitation patterns were recognized as: Region A (not apparent) and Region B (south and north
part of the basin) and Transition zone (central portion of basin), having both the frequencies are identified.
