Siphon Modeling in InfoSewer and Arc Map

Siphon Modeling in InfoSewer and Arc Map Atrribute Display by dickinsonre Siphon Modeling in InfoSewer and Arc Map Here is a typical view of  a siphon in InfoSewer, the rising links have a d/D of 1 and the dropping links typically have a d/D value less than 1.  The q/Q for the rising links is based on the slope and the dropping links typically have a q/Q less than 1 as the full flow is high due to the steep slopes.  You can show both the d/D and q/Q values in an Arc Map Display by using the following code.  I find it easier to first plot one variable using the InfoSewer Map Display followed by editing the TOC Properties for Pipes to show more than one variable at a time in the Label properties. Function FindLabel ([D_OVER_D],  [Q_OVER_Q] ) If IsNull([D_OVER_D]) then Exit Function FindLabel ="" &  FormatNumber([D_OVER_D],3) & "  d/D "  & "" &  FormatNumber([Q_OVER_Q],3) & " q/Q" End Function via Blogger http://www.swmm5.net/2013/08/siphon-modeling-in-infosewer-and-arc.html

SWMM 4 and SWMM 5 St. Venant Solutions Contrasted

SWMM 4 and SWMM 5 St. Venant Solutions Contrasted by dickinsonre SWMM 4 and SWMM 5 St. Venant Solutions Contrasted 1. Compute at time t+delta t the values of dQ/dt for the Links and dH/dt for the Nodes from the properties at time t 2 Iterate at least 2 times until either all nodes and links are converged or a maximum of 8 iterations are reached 3. Use the values of Q and H at time t+delta t for the new time step The SWMM5 Solution for Flow and Depth at each time step.  The new depth and new flow is always based on the old depth and old flow and normally converges fast as the flow is gradually varied.   The solution is iterative and implicitly uses the new depth and flow at each iteration. The SWMM4 Solution for Flow and Depth is solved Explicitly at each time step.  The new depth and new flow is always based on the old depth and old flow and and a half and full time step during the time step. via Blogger http://www.swmm5.net/2013/08/swmm-4-and-swmm-5-st-venant-solutions.html

Annual International Conference on modeling urban water systems, Feb 21-22 2013 in Toronto - call for papers

Annual International Conference on modeling urban water systems, Feb 21-22 2013 in Toronto - call for papers

My note, this is a conference well worth attending, the Convenor is Dr Bill James and the venue is described at the CHIWater link shown below.

Once again it's the time to request one or more abstracts for the Annual International Conference on the Modeling of Urban Water Systems (formerly SWMM users meeting), to be held Feb 21-22 2013 in Toronto (note the venue). As you probably know, this is the 46th (!) meeting in this extraordinary series. This year our featured speakers include many well-known scientists, researchers and engineers (listed on our website).
The meeting is well attended: your audience exceeds 100 folks in your specialty. Also, the meeting is inexpensive, highly-regarded, professional, friendly and collaborative. Proceedings are produced as a peer-reviewed, integrated archival-quality book (you get the previous year's monograph at this conference, two-for-one value). The conference addresses all aspects of urban water systems, including planning, design, construction, operation, monitoring, models, safety, and security; how to manage urban water systems including water supply, drainage, pollution control, domestic, municipal, and industrial waters and stormwater from surface water catchments or ground water; and real-time control along with education, outreach, and practical applications. We welcome abstracts in any and all of the following general categories:; LIDs and BMPs; TMDLs; Urban water disasters, Urban flood management, Land Use; Nonpoint Sources of Pollution; Pavement; Pathogens; Stormwater and Urban drainage; Potable Water Supplies; Water distribution; Water System utilities; and other management and socio-political issues. Although the discussion is generally technical, it meshes well with management and difficult topics connected to urban water and related to computer modeling. Please visit:
http://www.chiwater.com/Training/Conferences/conferencetoronto.asp
Please email your 1-page abstract(s) to me in the next week or so. Alternatively, if you need a more formal invitation or a flyer, let me know.  We look forward to seeing you and your colleagues in Toronto - you won't get a better deal in these economically-challenged times!

How to Use Two Control Curves in SWMM 5 to Simulate a Head Difference Rule

Subject:  How to Use Two Control Curves in SWMM 5 to Simulate a Head Difference Rule

How to Use Two Control Curves in SWMM 5 to Simulate a Head Difference Rule by dickinsonre Subject:  How to Use Two Control Curves in SWMM 5 to Simulate a Head Difference Rule  The SWMM 5 control rules for Real Time Control (RTC) do not allow the rule to be governed by the head across the orifice but does allow rules based on the depth, head and inflow at any node.  If you have an Orifice in which you want the Orifice to be open when the head difference across the Orifice is either less than or greater than zero then and closed when the head difference is close to zero then you can use two Orifices (Figure 1) and two rules (Figure 2) to control the orifice setting for Orifice1 and Orifice2.  In attached file the two rules have the settings set to two control curves.  Orifice1 will start open and close gradually as the depth at Node UPNode increases, Orifice2 will start closed and gradually open when depth in Node DNode increases.  Possible variations are to control Orifice1 based on the DNode and node UPNode to control Orifice2.  RULE Orifice1 IF  NODE UPNode  Depth >= 0 THEN ORIFICE ORIFICE1 SETTING = Curve RuleOrf1 PRIORITY 10 RULE Orifice2 IF  NODE DNode  Depth >= 0 THEN ORIFICE ORIFICE2 SETTING = Curve RuleOrf2 PRIORITY 10 Figure 1.  Two Orifice Solution Figure 2.

NASA computed Maps of Earth

NASA computed Maps of Earth

Die NASA hat sich ‘nen neuen Supercomputer angeschafft und simuliert mit dem die Erde, heraus kommen zum Beispiel so schicke Karten wie das Ding oben, und das Teil ist keinFoto, sondern ‘ne berechnete Grafik. Whoa!

This is not a photo of the Earth from some far-flung satellite. This is the output of a computer that has been programmed to take those laws of physics and apply them to the Earth. It has data about sunlight hitting the Earth (which includes variations for season); it knows about the composition of the Earth’s atmosphere and how the air’s temperature changes with latitude, longitude, and height; it can calculate how much water evaporates and where it rains or snows out; it accounts for fires, dust, the Earth’s rotation, the local geography, and even humanity’s effect on the environment.

And when it’s done, it can show us what the Earth looks like under various conditions. In this case, the blue swirls over the oceans trace sea salt; green is smoke from forest fires, white is sulfate particles (emitted from volcanoes and the burning of fossil fuels), and reddish-orange is dust blown about.  Slate Link
