Very interesting, Suraj, and quite a well done write-up.  I also do not see 
how the straight sides will stay that way.  Surely they will wash into 
gentle slopes.  Another consideration...what if someone falls in.  Can they 
he/she get out or would drowning possibility be high...esp a small child? 
That would worry me.  Even a dog would have a hard time climbing out without 
a slope.

Just my first impressions, hope they're useful, Lisa
