This study conducts a comprehensive analysis of hydrological patterns in the Kalisindh and Parbati Rivers,
highlighting the Eastern Rajasthan Canal Project (ERCP) as pivotal for bolstering regional water security.
Employing an array of data sources, this research utilizes Polynomial Regression and neural network forecasting
to dissect flow patterns, identifying significant virgin flow peaks in the mid-1980s and early 2000s for the
Kalisindh River, and a notable peak in 2006–2007 for the Parbati River. Analysis reveals that the specific
discharge rate of the Parbati River is diminishing at twice the rate of the Kalisindh River, with annual decreases
of approximately 0.0038 cumecs/km2 for Parbati, compared to 0.0019 cumecs/km2 for Kalisindh. Furthermore,
runoff volumes indicate that the Parbati River, specifically at the Khatoli Gauge & Discharge (G&D) site, experiences
significantly higher runoff—28,137.912 million cubic meters (MCM)—in contrast to 15,795.094 MCM
for the Kalisindh River at the Barod G&D site. The findings accentuate the necessity for science-based water
management strategies to effectively combat water scarcity and climate change impacts. The ERCP emerges as a
crucial initiative for sustainable management of the Kalisindh and Parbati Rivers in Rajasthan, underscoring its
potential to serve as a model for sustainable water and river basin management.
