KARWAR: Heavy rainfall in the past two days has caused large-scale erosion on Rabindranath Tagore beach and on Devbag beach here. Many coconut trees in the municipal garden on Rabindranath Tagore beach had been uprooted. The pergola built on the beach is on the verge of a collapse. The toy train track located close to the sea beach is threatened by tidal waves. Many low-lying areas, including Khursawada in the town, Keni near Ankola and Arga near Karwar Naval Base were inundated. The rainwater had entered many houses in Khursawada on Monday making life difficult for the residents. Farming was affected in Ankola taluk. Five houses reportedly collapsed in Bhatkal.
