Date: Thu, 1 Feb 1996 20:06:26 -0400 From: Claude Collerette To: ag025@ccn.cs.dal.ca Subject: SWCS Site Hi I've left you a message on your answering machine today to tell you that I was really impressed with the quality of information available on your site. As an engineer I' m working presently on a master drainage plan involving a retention lake. There will be two sedimentation and "a cosmetic" (e.g not planned for treatment) wetland due to lack of space because of an over-control situation. I have two questions: 1) In you site, it is written that the wetland is limited in efficiency by the volume of water it can retains (4 to 8 day). Is this value is a minimum for efficiency in polutant and nutriments (TP...) removal? 2) Is the Dillon model on Exel available on a site? If not, is there a way to create one with available information or litterature? If available soon I would really appreciate if you could leave me a note of when and where. Again "chapeau" for your site. It's rare that there is detailed information on a subject and accurate. I'm building a site at this moment and I will tell you when it will be operational. Many Thanks.
