Overland Flow Path

Hi Ramki,

  Welcome aboard !!   The phrase you mentioned was unknown to me (though the wording indicated what it might mean).   So I went Googling!!

  Go here for explanation :-

Thanks Benny, good article!

For those who can't be bothered clicking the above link here is what it says

Overland flow flooding

Overland flow is excess rainfall runoff from homes, driveways and other surfaces.   Overland flow flooding is water that runs across the land after rain, either before it enters a creek or stream, after a creek or stream breaks its banks, or after rising to the surface naturally from underground.  Overland flow flooding tends to affect localised areas rather than the whole city at once.

What you can do to manage overland flow flooding

Overland flow flooding can be unpredictable and its severity will depend on the amount of rainfall.

You can understand overland flow flooding by looking at the natural overland flow path through your property and taking appropriate steps to prepare and protect yourself and your home.  Consider these natural flows when you are looking to renovate, build a fence or put in a shed.  Remember where water will flow.
