    InfoWorks WS – Using SQL to compare two simulations

    comparison_grid_of_two_simulations

    Download Paper – Comparison Grid of Two Simulations Using SQL

    The SQL tool in InfoWorks can be very powerful in quickly comparing two simulations. In the attached paper a method is described to produce a grid and select links with the estimate of the links that may have a discoloration risk compared to a base simulation. The criteria that is used in this example is an example only and engineering judgement is required to set the limits relevant for your network and organisational standards.

        How to Use Trace Upstream, Domain Manager and Facility Manager in InfoSewer to Find the CE

        InfoSewer and H2OMAP Sewer do not have table of node continuity errors only an overall continuity error (CE) balance.  If you have a continuity error then you can use the process of divide and conquer to find the location of the continuity error.  Start at the Outlets and using the Trace Upstream command, Domain Manager and Facility Manager take out whole sections of the network until you isolate the section of the network with the continuity error  (Figure 1 and Figure 2).

          InfoNet SQL – How Many Shifts Worked by Each Team?

          Here’s my problem, I want to find out how many shifts have been worked by each of the individual crews my organisation on a survey, clean or repair campaign. To do this I once again turn to SQL to achieve what I’m after. Let’s flesh out the problem that I’m trying to solve; let’s say for example that I have imported CCTV data into my network and I have in each of these, recorded in the time and date of survey (when_surveyed field) and whom carried out the survey (surveyed_by field). I want to produce a table of each team leader and a number of the individual days that were worked by each of these.

          For this SQL I will be using the ‘RANK’ functionality, you may want to brush up on this by reading one of my previous post where I used it:

          http://blog.innovyze.com/2014/07/08/infonet-sql-using-an-objects-rank-field/

          And for further clarification the following in italics is from the InfoNet HELP:

          RANK

          It is possible to use the ‘rank’ of an object, where the rank is the position that the object appears in the list. Rank can only be used where there is an ORDER BY clause and can only appear on the right hand side in an assignment in a SET clause e.g.

            InfoSWMM/H2OMAP SWMM Fully Supports the EPA SWMM-CAT Climate Change Adjustment Tool

            The Innovyze products InfoSWMM and H2OMAP SWMM are always based on the current version of EPA SWMM 5 (the current version is 5.1.007) and we are pleased to announce that the current version of both InfoSWMM and H2OMAP SWMM (v13) is also able to use the output of the EPA’s Storm Water Management Model Climate Adjustment Tool (SWMM-CAT) to help our users estimate future changes in temperature, evaporation and rainfall for their simulation modeling.

              Vertical Roughness Differentiation in InfoSWMM for a Link

              The Vertical Roughness Threshold allows the user of InfoSWMM or H2OMAP SWMM to have a simple differentiation of roughness in a link.  The Threshold depth which is entered as a fraction of the total link depth allows the simulation of lower or higher roughness at the bottom of the link compared to the top of the link.  The lower or higher roughness is entered as the Vertical Roughness value in the InfoSWMM Attribute Table of DB Table for the link hydraulic data.

              Top and Bottom Roughness

              1. The Vertical Roughness Threshold is a fraction and the Threshold depth calculated from this fraction will be the Vertical Roughness Threshold Fraction * Maximum depth. If the Maximum depth is 3 meters and the Vertical Roughness Threshold is 0.5 then the dividing depth is 1.5 meter (Figure 1 and Figure 2).

              2. If the depth in the link is higher than the Threshold depth it will use the link manning roughness n value. If the depth is in the link during the simulation is less than the Threshold depth it will use the Vertical Roughness n value (Figure 2).

                Initialising Pumps in InfoWorks WS UPC Scripts

                Have you ever noticed that the INITIALISE command doesn’t always set the initial status of a  pump ?  Well there is a reason….

                If you have a UPC script like the following

                INITIALISE PUMP = OFF
                RULE RULE1
                IF NODE X PRESSURE < 72.0 THEN
                PUMP = ON
                ELSEIF NODE X PRESSURE > 75.5 THEN
                PUMP = OFF
                ENDIF

                Check the log file for messages like this
                00:00 PST Y set by Rule: RULE1; Action: Pump 1 ON Activated. (Local script line 4.)

                What is happening is that as there is no initial pressure set on Node X (i.e it is not a Reservoir, Well or Fixed Head) the starting pressure is 0 – hence the pump is turned ON.

                If this is not the behavior you wish to model then try explicitly defining what is to happen at the first timestep as this will overcome the initialization statement being overruled by subsequent conditions in the rules.

                RULE RULE1
                IF RUN SIMTIME = 00:00 THEN
                PUMP = OFF
                ELSEIF NODE X PRESSURE < 72.0 THEN
                PUMP = ON
                ELSEIF NODE X PRESSURE > 75.5 THEN
                PUMP = OFF
                ENDIF

                  The new ‘Mesh Level Zones’ in InfoWorks ICM version 5.5 and their Potential Applications

                  Exciting new functionality has been added to InfoWorks ICM version 5.5 to allow improved 2D mesh editing.  Mesh level zones are objects added to the network geometry which are used as part of the mesh generation process.  They offer improved functionality compared to the existing Mesh Zone mesh editing tools.  The Mesh Level Zones allow the users to interpolate levels, specify vertices with different heights or adjustments, all of which allow the user to represent or create a wider array of surface features within the 2D mesh.  The below document explains more about using them in InfoWorks ICM 5.5 and their potential applications:-

                    InfoSWMM and H2OMAP SWMM and their Relationship to FEMA Approved SWMM 5 Engines

                    The purpose of this note is to show how InfoSWMM is related to various SWMM 5 engines. InfoSWMM is a ESRI Arc Map Interface to the properties of the SWMM 5 engine using model development tools created by Innovyze for InfoWater and InfoSewer. It uses a recompiled SWMM 5 engine for the purposes of integration with Arc GIS but the underlying engine code is the EPA SWWM 5 code. InfoSWMM has very good import and export tools for reading and writing SWMM 5 files. InfoSWMM does not have to be on the official FEMA list as it uses and exports the FEMA approved current SWMM 5 engine.

                    SWMM 5 has been approved by FEMA since 2005. Figure 1 shows the versions of SWMM that have been approved by FEMA. It is approval that continues each time a new EPA SWMM 5 is released. Innovyze InfoSWMM and H2OMap SWMM use a recompiled SWMM 5 engine based on the current version of EPA SWMM (Figure 2). The match between the EPA Engine and InfoSWMM is shown in Figure 2. EPA SWMM 5.x was produced by the Water Supply and Water Resources Division of the U.S. Environmental Protection Agency’s National Risk Management Research Laboratory with assistance from the consulting firm of CDM Inc under a Cooperative Research and Development Agreement (CRADA) in 2004. Innovyze released the first version of InfoSWMM at the same time and keeps up to date with the latest SWMM 5 releases. The EPA SWMM 5 version used in the current version of InfoSWMM is listed at the top of the text output file (Figure 3).

                    We will show in the rest of this note how you compare the InfoSWMM engine results to the EPA SWMM 5 engine results. There are many processes to compare: RDII, Runoff, Groundwater, Snowmelt, Quality, Routing (Figure 4). The InfoSWMM model is exported to SWMM 5 (Figure 5) with the message board showing any problems in the export (Figure 6). The exported file can be immediately imported into SWMM 5 (Figure 7). Any files created by InfoSWMM such as RDII, Runoff or Hot Start files have the same format as SWMM 5 and can be used immediately in SWMM5 (Figure 8 and Figure 9). The process flows are the same in InfoSWMM and SWMM 5 (Figure’s 10, 11 and 12) as the underlying engine is the same (Figure 13) for the compared model (see Figure 14 for a comparison view of InfoSWMM and SWMM 5).
