Here is a link to everything that you would ever want to know about
Houston's most recent, and worst, flood.  There wasn't a lot of national or
international media coverage of this event, because the timing coincided
with the build-up of relentless hype over the Timothy McVeigh execution.
Nevertheless, even for a city that is used to occasional hurricanes and
flooding, this was a devastating event.

This is a special website maintained by the Houston Chronicle. Here you can find amazing photo collections, videos, articles describing the devastation,
etc.  My most amazing discoveries were the rainfall map and the photos of
Interstate Highway 10 pavement broken into thousands of pieces.  The
northeast part of the city got nearly one meter of rainfall, while some
areas (like Katy) received only about one-tenth of that.  This is positive
proof that God likes Bill Polhemus! <grin>

You may be right.In such extra ordinary situation even a super pump may not
work. But my question was (hydrology design & well designed catch basins are

necessary to train disposal of these water, but thats beside the point), in
such cases where water manages to accumulate in underpasses, there should be

well designed pumping mechanism to handle such problem. After all its human
life thats at stake!, regards.
