How to Use Bing Maps in InfoSWMM as a Basemap
Note: How to Use Bing Maps in InfoSWMM as a Basemap
Note: How to Use Bing Maps in InfoSWMM as a Basemap
A great feature of Arc GIS 10 is the ability to use background maps from Bi
Step 1. Set the Current Coordinate System for the intended network.
Step 2. Add the Aerial Basemap from Bing Maps.
Step 3. The Base Map has to be clipped and zoomed.
Step 4. Zoom to your network and clip the rest of the Map out of the Maximum Extents.
Step 5. Set the Maximum Extents of your Network using the Data Frame Tab in Data Frame Properties.
Step 6. You can also set the background color for the area outside of the clipped Base Map if you so desire using the Frame Tab.
Step 7. You now can add nodes and links and view the locale using Google Street View or other using the Tools Preferences.

Connecting Infrastructure To The Internet from the Dish
Engineers can now link a building's rainwater catchment system to weather predictions from the Internet. Alerted city services can then empty water storage basins so that stormwater doesn't flood our sewers:
It may sound like a trivial problem, but the EPA estimates that the U.S. has $13 billion invested in wastewater infrastructure alone. More importantly, the majority of America's largest cities--more than 700 in all--dump millions of gallons of raw sewage into our waterways every time it rains, because their sewer and stormwater systems were designed a century ago. ...
Giving building planners the assurance that they'll always have access to a free water supply means they can actually use it. And putting these on enough buildings could go a long way to solving the problem of combined sewer and stormwater systems being overwhelmed when it rains.

Sensitivity Analysis in InfoSWMM and H2OMAP SWMM
Subject: Sensitivity Analysis in InfoSWMM and H2OMAP SWMM
It is easy to perform sensitivity analysis
Figure 1. Physical Data used in the Calculation of Surface Runoff using the Non Linear Reservoir Routing method in SWMM 5.
 
Figure 2. The base scenario for our sensitivity analysis.
There are seven main steps in the sensitivity analysis of the width:
Step 1. Use the Scenario Explorer to make Child Scenarios from the Base Scenario. For ease of understanding we will name each of the Child Scenario's the percent change in the width parameter. Thus, W-50, will be the Base Width Plus 50 percent.
Step 2. Use the Dataset Manager to create different Subcatchment Sets that will be used for each of the Scenario's. Again for ease of understanding we will use the name S_W+50 etc for the Sets to match the change in the Width Parameter.
Step 3. Use the Scenario Manger to choose the right Subcatchment Set for Each Scenario.
Step 4. Use the Database Editor to Edit and modify the Width of Each Subcatchment Set.
Step 5. Use the Block Edit tool to multiply the Base Width Value by the needed value, 1.25, 1.50, 0.75, 0.50
Step 6. Use the Batch Simulation Command to run all of the Scenario's.
Step 7. Use Report Manager and the tool Compare Graphs to graph the results of Each Scenario together.
Step 8. In Report Manager you can produce a table that shows the runoff for each of the different scenarios.

How InfoSWMM and H2oMAP SWMM Reads CUHP Hydrographs
Note: The Colorado Urban Hydrograph Procedure (CHUP) 2010 version generates a SWMM 5 Inflows Files containing a time series of flow inflows for 1 to many nodes (Figure 4 and Figure 5). The created Inflows file (Figure 2) can be imported intao InfoSWMM and H2MAP SWMM without any alteration by using the Files command in Run Manager (Figure 1) and graphed using the Output Manager of InfoSWMM and H2OMAP SWMM (Figure 3).
Figure 1. Location of Files Command in Run Manager
The inflows will be read from the Inflows file, which has this format:
Figure 2. Header format of the CUHP Exported Hydrograph
InfoSWMM and H2oMAP SWMM will match the Node Names in the Inflows file to the network node names and import and interpolate the inflows based on the Inflows time step and your hydraulic time step to generate Lateral Inflow Hydrographs

Mind The Crap From the Dish
Sally Aldee fell in the Thames and gashed her leg, a prospect that horrified every medical professional she met. She subsequently traced the river's pollution from Victorian times to today:
The river – which by the way was both the source of the city’s drinking water and the repository for all its poop – became choleric and pestilent. In the summer of 1858, the fumes became so bad they got a name. The "Great Stink" forced members of Parliament to write the legislation that gave the all-clear to Joseph Bazalgette, London’s chief engineer of public works, to build the two massive interceptor sewers that catch London’s sewage and run-off before they’re belched into the Thames. To this day, these brick and mortar Victorian artifacts comprise the backbone of London’s sewer system. ...

Storage Volume vs Depth Equation in SWMM 5
A storage node in SWMM 5 can have either a functional form or a tabular depth/area table. The area functional form of a storage node is:
Area = A * Depth^B + C and the Volume has the form in node.c of the SWMM 5 of
Volume = A/(B+1)*Depth^(1+B) + C*Depth
For example if C is 25 square meters, A is 20 and the exponent B is 0.5 we get the following values for area and volume and you can also plot a Scatter Plot of Volume vs Depth in SWMM 5 (Figure 1).

Lambda Calculus in the SWMM 5 Dynamic Wave Solution
SWMM 5 uses the method of Successive under-relaxation to solve the Node Continuity Equation and the Link Momentum/Continuity Equation for a time step. The dynamic wave solution in dynwave.c will use up to 8 iterations to reach convergence before moving onto the next time step. The differences between the link flows and node depths are typically small (in a non pumping system) and normally converge within a few iterations unless you are using too large a time step. The number of iterations is a minimum of two with the 1st iteration NOT using the under-relaxation parameter omega. The solution method can be term successive approximation, fixed iteration or Picard Iteration, fixed-point combinatory, iterated function and Lambda Calculus. In computer science, iterated functions occur as a special case of recursive functions, which in turn anchor the study of such broad topics as lambda calculus, or narrower ones, such as the denotational semantics of computer programs (http://en.wikipedia.org/wiki/Iterated_function).
In the SWMM 5 application of this various named iteration process there are three main concepts for starting, iterating and stopping the iteration process during one time step:
· The 1st guess of the new node depth or link flow is the current link flow (Figure 3) and the new estimated node depths and link flows are used at each iteration to estimate the new time step depth or flow. For example, in the node depth (H) equation dH/dt = dQ/A the value of dQ or the change in flow and the value of A or Area is updated at each iteration based on the last iteration’s value of all node depths and link flows.
· A bound or a bracket on each node depth or link flow iteration value is used by averaging the last iteration value with the new iteration value. This places a boundary on how fast a node depth or link flow can change per iteration – it is always ½ of the change during the iteration (Figure 1).
· The Stopping Tolerance (Figure 2) determines how many iterations it takes to reach convergence and move out of the iteration process for this time step to the next time step.
Figure 1. Under relaxation with an omega value of ½ is done on iterations 2 through a possible 8 in SWMM 5. This is not done for iteration 1.
Figure 2. if the change in the Node Depth is less than the stopping tolerance in SWMM 5 the node is considered converged. The stopping tolerance has a default value of 0.005 feet in SWMM 5.0.022.
Figure 3. The differences between the link flows and node depths are typically small (in a non pumping system) and normally converge within a few iterations unless you are using too large a time step. The number of iterations is a minimum of two with the 1st iteration NOT using the under-relaxation parameter omega.

Subject: InfoSWMM Selection Set and Domain Manager
Subject: InfoSWMM and H2Map SWMM Selection Set and Domain Manager
You can use the Domain to easily make selection sets using these two steps. You make a Domain which is the areas of the network you are interested in at the current time and then save your Domain of Interest in a Selection Set.
Step 1: Go to Domain Manager and use Map Selection, Query or the Network to make a domain
Step 2. Go to Selection Sets in the Operation Tab of the Attribute Browser and make a New Set and load the domain into your set.
