The Water Resources Department (WRD) has floated tenders for executing two major flood- mitigation works in Tiruchi district, including the construction of a Gabion grade wall to reinforce a vulnerable stretch of the Kollidam river bund at Kariyamanickam near Tiruchi to prevent erosion and flooding.
The left bank of the Kollidam suffered erosion at Kariyamanickam during heavy discharges in the river in 2022 and 2024. Major breaches were averted, thanks to the timely detection of the vertical spits and erosion by the officials. The bund was temporarily reinforced using scores of lorries of stone boulders on both the occasions.
