 Recently I am modeling two rainwater gravity drainage systems with two separate Outfalls. My task is to connect them together and to analyze the hydraulic flow distribution after the connection. 
 My question is: is there any suggestions or rules</description><dc:language>en-US</dc:language><generator>Telligent Community 12</generator><item><title>RE: Civil Storm.

&lt;p&gt;You can model the interconnection with a normal conduit element if a pipe will be used to connect the real systems. Set the start and stop invert accordingly - most likely they are some distance above the bottom of the manhole. With the Implicit or Explicit dynamic solvers, the hydraulics of the interconnection will be handled automatically. As the water level rises above the invert of the interconnection pipe, water will flow to the other side as you would expect.&amp;nbsp;&lt;/p&gt;
&lt;p&gt;If you have an orifice or weir plate used to control the flow that passes through the interconnection, you can specify a start or stop control structure in the conduit, otherwise the hydraulics will be controlled by the size of the conduit itself. See: &lt;a href="/products/hydraulics___hydrology/w/hydraulics_and_hydrology__wiki/35057/using-start-and-stop-control-structures-for-conduits-and-channels"&gt;Using Start and Stop Control Structures for conduits and channels&lt;/a&gt;&lt;/p&gt;

&lt;p&gt;Two separate systems.&lt;/p&gt;
&lt;p&gt;Connection is needed to check if one system, that is more loaded with rain water could overflow to another system, which is less loaded with rain water.&lt;/p&gt;

&lt;p&gt;Are you trying to ascertain the combined flows from the two systems at this point?&lt;/p&gt;
&lt;p&gt;If that is the case then you can simply put both the rainwater gravity drainage systems into one &amp;quot;outfall&amp;quot;. If you are using conduits, you can have two conduits representing the end connections from your two systems terminating into a single outfall.&lt;/p&gt;
&lt;p&gt;Something like this;&lt;/p&gt;
&lt;p&gt;&lt;img alt=" " border="0" src="/cfs-file/__key/communityserver-discussions-components-files/5925/4010.Img.jpg" /&gt;&lt;/p&gt;
&lt;p&gt;Does this help?&lt;/p&gt;&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item></channel></rss>
