“The local hydrological regime of Patiala is influenced by the lateral runoff conveyed from Mohali sector via the Fatehgarh Sahib sub-catchment. As per the latest telemetry, the gauge at Fatehgarh is presently in a quasi-steady state, indicating no abnormal hydrograph surge” said an irrigation expert.
The current rainfall intensity over the Patiala Nadi catchment is sub-threshold and has not generated a peak hydrograph that could translate into a flood wave downstream.
The Badi Nadi gauge at Patiala registers 2.4 ft, which corresponds to a discharge of approximately 997 cusecs, whereas the codified danger mark is 12 ft with a design flood capacity of nearly 10,000 cusecs. This reflects an operational buffer of more than 75% in terms of freeboard and over 90% in discharge margin. Flow continuity through the urban storm drainage and the natural nallah section remains hydraulically stable, with no backwater effect observed at present.
On the basis of current hydrodynamic parameters, no exigency for evacuation or removal of belongings is technically warranted. The system is operating well within permissible flow capacity, and the probability of an imminent threshold breach is statistically insignificant under the prevailing rainfall conditions.
