The basin or sinkhole then fills with water, causing flooding. Sinkhole flooding can also happen simply because water enters a sinkhole extra shortly than it may possibly drain via a conduit or other outlet. The last flooding scenario occurs when an overflowing river is connected to a sinkhole through underground streams and conduits.
