Country of Samoa Chooses Innovyze Smart Water and Sewer Network Modeling Solutions   Samoa Water Authority Selects H 2 OMAP Water and InfoWorks CS Broomfield, Colorado USA,  May 29, 2012  — Innovyze, a leading global innovator of business analytics software and technologies for wet infrastructure, today announced that the Samoa Water Authority (SWA) has chosen Innovyze industry-leading  H 2 OMAP Water  and  InfoWorks CS  software for water distribution and sewer collection modeling and design of the Samoan network. The selection further substantiates Innovyze’s leadership position in geospatial hydraulic infrastructure modeling and management across the globe. Established in September of 1993, the SWA is the national supplier of water services to Samoa’s 180,000 citizens. The authority manages five conventional slow-sand filter water treatment plants and five newer rapid-sand filtration package treatment plants. All treated supplies are chlorinat...

Saving to previous versions of ArcGIS in InfoSWMM and InfoSewer Once you open and save an existing map document (.mxd file) using ArcGIS 10, the map can no longer be opened with earlier versions of ArcGIS because it will now reflect the new functionality added at 10. Similarly, new documents you create with 10 also cannot be opened in earlier versions of the software. However, you can use the  Save A Copy  command to make a copy of a map document so you can open and work with it in previous versions of ArcGIS. With ArcGIS 10, you can save to ArcGIS 9.3, 9.2, 9.0/9.1, or 8.3. ArcGIS 9.0 and 9.1 map documents are directly compatible with each other and those versions of the software. Each new version of ArcGIS introduces functionality and properties that aren't available in previous versions. When you save a map document, layer file, or 3D document to a previous version of ArcGIS, the format of the file is changed to eliminate properties not available in...

Subject:    Link Iterations in the SWMM 5 Dynamic Wave Solution Link Iterations in the SWMM 5 Dynamic Wave Solution by  dickinsonre Subject:    Link Iterations in the SWMM 5 Dynamic Wave Soluti on Each of the links in the SWMM 5 network can use up to 8 iterations to reach convergence during a time step in the dynamic wave solution of S WMM 5.  The rules governing the number of iterations are: 1.        A minimum of 2 iterations per time step with the 1 st  iteration NOT using the underrelaxtion parameter of 0.5 (Figure 1) 2.        If both the downstream and upstream nodes are converged then the link drops out of the iteration process during the time step (Figure 2) 3.        The number of iterations for ea...

Subject:   How is the St Venant Equation Solved for in the Dynamic Wave Solution of SWMM 5? How is the St Venant Equation Solved for in the Dynamic Wave Solution of SWMM 5? by  dickinsonre Subject:    How is the St Venant Equation Solved  for in the Dynamic Wave Solution of S WMM 5? An explanation of the four St. Venant Terms in SWMM 5 and how they change for Gravity Mains and Force Mains. The HGL is the water surface elevation in the upstream and downstream nodes of the link. The HGL for a full link goes from the pipe crown elevation up to the rim elevation of the node + the surcharge depth of the node.  The four terms are: dq2  = Time Step * Awtd * (Head Downstream – Head Upstream) / Link Length or dq2  = Time Step * Awtd * ( HGL ) / Link Length Qnew  = (Qold – dq2 + dq3 + dq4) / ( 1 + dq1) when the force main is full dq3 and dq4 are zero and Qnew...

Subject:   SWMM 5 Precipitation Options SWMM 5 Precipitation Options by  dickinsonre Subject:   SWMM 5 Precipitation  Options You can have design storms, monitored storms of any length of the time from minutes to centuries, use intensity, volume or cumulative precipitation, use both rainfall and snowfall in the same rain gage depending on temperature, use both time series or external files for the rain gage and have unlimited rain gages with the limitation of one rain gage per subcatchment . via Blogger  http://www.swmm5.net/2013/08/ swmm-5-precipitation-options. html
