An interesting post from Starts with a Bang about moving clouds in one large Image. http://scienceblogs.com/startswithabang/2013/11/30/weekend-diversion-a-stacked-photo-fantasy/ The daytime photo techniques are incredible for showing how clouds move over time and appear to smear out across the sky, painting a glorious natural picture. Image credit: Matt Molloy. When even more frames are added, it can produce skies that look like they’re straight out of a painting. Image credit: Matt Molloy. But the photos that blew me away the most were the ones that combined day-and-night in a way I’d never before imagined: not only with sunsets and clouds, but with the color of the aurorae thrown in there, too!

There’s also  an interview  with the 29-year-old Canadian photographer, where he reveals that these sunset track images typically consist of 100 to 20

Introduction:  This set of blogs uses the 1000 year rainfall/runoff/hydraulics model that you can download at http://swmm2000.com/forum/topics/1000-year-simulation-with-rainfall-in-swmm-5 to show the inner workings of SWMM 5 and by extension InfoSWMM and H2oMap SWMM using a QA/QC version of SWMM 5 with extended graphics.   I always hope that seeing the inner workings of a SWMM 5 feature helps to understand the code, sensitivity and importance of a parameter.   It also helps show sometimes when a parameter is not important.   Discussion:   In this blog we look at the Runoff total over the 100 year period, graph the runoff (Figure 1) and show the Mean, Total and Peak Runoff using the Statistics Command in SWMM 5.   The Frequency plots shown in Figure 1 are made using event separation time of 6 hours.  The number of Runoff Events over the 100 year period is 11,144 events.   The details of the simulation are shown in Figure 2. Figure 1.   Runoff from One Watershed for a 100 Yea

The overland flow junction does have an invert and rim elevation, it is usually part of a road system and you can drain Subcatchment flow to the overland flow junction.   If an Inlet node is flooded the excess water can flow out of the inlet to the street through the overland flow junction.  There is a virtual link between the Inlet Junction and the Overland Flow Junction .

What are the Options for LID Inflow and Outflow in SWMM 5? The Runoff Surfaces in SWMM 5 are: 1.       Pervious area with either Green Ampt, Horton or CN Infiltration 2.      Impervious area without Depression Storage or Initial Losses 3.      Impervious area with Depression Storage or Initial Losses Outflow Options for the Runoff in SWMM 5 are: 1.       Pervious from Impervious 2.      Impervious from Pervious 3.      The Subcatchment Node Outlet Or Another Subcatchment based on the Outlet Name The LID inflow in SWMM 5 can be from: 1.       The pervious area 2.      The pervious area plus a fraction of the impervious area 3.      The Rainfall on the LID Area 4.      A LID can cover the entire Subcatchment and can get all of the Flow from another Subcatchment as well as the Rainfall on the Subcatchment The LID outflow in SWMM 5 can be to: 1.       The outlet of the Subcatchment 2.      The pervious area of the Subcatchment Note: These options also apply to InfoSWMM and H2

The Effect of the LID Percent Impervious Treated in SWMM5 If you use the option percent impervious treated for LID's on a Subcatchment then a percent of the impervious flow is routed to the LID.  For example, 50 percent of roof runoff to a LID Swale.  It has the impact of reducing the peak and total runoff fro the whole Subcatchment but increases the LID only flow.  From the SWMM 5 help file  " The percent of the impervious portion of the subcatchment's non-LID area whose runoff is treated by the LID practice. (E.g., if rain barrels are used to capture roof runoff and roofs represent 60% of the impervious area, then the impervious area treated is 60%). If the LID unit treats only direct rainfall, such as with a green roof, then this value should be 0. If the LID takes up the entire subcatchment then this field is ignored" Figure 1.   LID's get 50 percent of the impervious flow which reduce the overall flow from the Subcatchments. Figure 2.  No Impervious Flo

47th Annual International Conference Toronto, Canada February 26-27, 2014 Call for papers Have you implemented a good idea recently? Do you have hard facts and figures? If so, you should consider presenting at this conference. Your audience will be large (>100) and comprise equally active and thoughtful professionals. The annual  International Conference on Stormwater and Urban Water Systems Modeling  is a forum for professionals from across North America and overseas to exchange ideas and experience on current practices and emerging technologies. This is the 47th annual SWMM Users Group Meeting, the 23rd in the current series of annual Toronto conferences, and the 34th to be held in Canada. The atmosphere is relaxed, presentations are of a high standard and by accepting papers up to the last few weeks before the event, a spontaneity is achieved which gives this conference special character.
