WSPGW is a computer software to calculate hydraulic grade line for storm drain systems. I have put together an illustration book to share my knowledge on how to use it. Attached is the table of contents of the book. I am trying to sell it to cover some expense. If interested, please visit my web page at www.terrahydra.com and email me.
