Guidelines for Help Files and Examples

Guidelines for Help Files and Examples

I have written a lot of software and have used a lot of software in my
career. I thought it would be good for me to list some guidelines I
try to follow when using and making software. I emphasis the word
guidelines as I often do not follow these guidelines. Think Wish list
when you read guideline. I have actually learned a lot from using
software without access to the source code though knowing the source
code is always very helpful.

1. Some mention in the help file of the feature – at least some place to start the process of understanding.
2. Help file information to explain the background of the feature and common values for the parameters of the feature,
3. An example of how the feature is used – How do you even get it to work?
4. Rules and sensitivity of the feature – how is this feature linked to other features, what are the rules for using the feature and how sensitive is the feature?
5. An example of the feature along with 
6. A bullet list of how to use the feature 
7. How do I see if the feature is actually working?  Some options or features are not always used 
8. More to come in the future  

Innovyze Releases SWMMLive: Real-Time Stormwater, Wastewater and Watershed Modeling

Revolutionary New Product Equips Wastewater Utilities with Unprecedented Capabilities for Decision-Making and Real-Time Control Optimization

Broomfield, Colorado, USA, December 17, 2013

Redrawing the boundaries of collection system modeling, Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced the worldwide release of SWMMLive for real-time operational forecasting and management of urban drainage systems. The pioneering release provides wastewater utilities timely, accurate and reliable forecasts of what will happen within a catchment, based on past and current observations of a multitude of parameters along with future rainfall predictions. It also helps them identify flood-vulnerable assets and formulate sound remediation/mitigation strategies.

The product combines the comprehensive urban drainage modeling capabilities of InfoSWMM (and H2OMAP SWMM) with sophisticated real-time operational forecasting, early warning, and emergency management. This debut reflects Innovyze’s vanguard position in the wastewater industry and its ongoing commitment to delivering pioneering smart water solutions that enhance the safety, reliability and sustainability of the world’s hydraulic infrastructure.

Advances in computer simulation and hardware have made real-time operation of stormwater, wastewater and combined systems a reality.SWMMLive allows both large and small utilities to manage their collection systems more efficiently and effectively than ever before. This powerful risk assessment and real-time decision making tool enables managers and operators to consider the influence of a full range of catchment factors in three key areas: management of flooding and reduction of unregulated discharges; optimization of storage, green alternatives and existing infrastructure, leading to savings on capital works; and optimization of pumps to lower energy costs and reduce CO2 emissions.

SWMMLive can directly import any InfoSWMM or H2OMAP SWMM project and is designed to work automatically. Once a system is configured, real-time data is continually and automatically harvested and quality checked. This data can be defined by a number of parameters, including observed and forecasted radar rainfall, online water quality measurements, and ancillary structure and pump operation time series. Simulations are carried out automatically at a user-defined frequency using the full hydrodynamic and functional capabilities of InfoSWMM (and H2OMAP SWMM), including water quality assessment, pollution prediction, urban flooding, green LID and BMP alternatives, and real-time control. Simulation frequency can change in response to user-defined conditions. For example, increased rainfall intensity can trigger a reduction in the interval between simulations.

Warnings or alerts triggered during the forecast period are instantly displayed via the rich SWMMLive user interface, allowing system operators to see at a glance which areas need attention and what actionable options might be taken. Comparison alerts can be used to highlight differences between observed and modeled results, enabling users to refine their models — creating unprecedented confidence in simulation results.

SWMMLive also allows operators to perform additional simulations that explore alternative real time control scenarios — such as the impact of switching on a pump earlier than planned — and quickly seeing the effect of these changes on the system. The wide range of capabilities in SWMMLive allow it to be used as a key tool in the decision making process, enabling operators to take action to avoid system issues, release timely alerts, and quickly deploy response teams if necessary.
“Real-time urban drainage modeling is an invaluable tool for wastewater utility planning, engineering and water quality departments,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, F.ASCE, President, COO and Chief Operating Officer of Innovyze. “However, translating these benefits to real-time operations has proven difficult. With SWMMLive, Innovyze has changed the paradigm for how and where urban drainage models can be applied. This milestone solution will help wastewater utilities worldwide harness the power of real-time data, scenario planning, and predictive modeling to transform the operation and management of their collection systems and anticipate and mitigate the effects of extreme weather-related events. It is the ultimate decision support system for operating and sustaining safe, reliable and efficient infrastructures while effectively protecting public health and our waterways.”

Innovyze Introduces ICMExchange, First Fully Customizable Integrated Catchment Modeling Solution for Power Decision Making

New Programmer’s Toolkit for Industry-leading InfoWorks ICM To Support Comprehensive Urban and Rural Catchment Managment As Adoption Expands

Broomfield, Colorado, USA, December 10, 2013

Expanding the boundaries of smart water network innovation, Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced the release of ICMExchange, a full-featured programmer’s toolkit for its industry-leading InfoWorks ICM. ICMExchange provides scripting language access to the features of the modeling software, enabling users to build, access, and modify model databases and seamlessly interface with other software to suit application-specific needs. These abilities empower them to work more efficiently and instantly get the reliable information they need to make better design and operational decisions for optimal performance.

InfoWorks ICM has rapidly become the solution of choice for integrated river, sewer and overland flow modeling among utilities, municipalities, local authorities and their consultants around the world. A key hallmark is its dynamic integration of one-dimensional (1D) hydrodynamic simulation of flows in rivers, open channels and pipe networks and two-dimensional (2D) hydrodynamic simulation of surface flooding in the urban environment and river floodplain. The combination, achieved through an implicit coupling of 1D and 2D flow equations, provides a powerful solution for simultaneously modeling below-ground and above-ground elements of catchments to accurately represent all flow paths and improve understanding of processes occurring in the holistic environment. The software also takes interactions of natural and man-made environments into account, and effectively simulates the impact of polluting runoff and effluent from urban areas on water quality. Such advanced features give wastewater utilities greatly enhanced capabilities in a number of critical areas. They include flood risk prediction; cost-effective drainage design and management support; online urban flooding forecast development; conception and evaluation of sound and reliable urban catchment strategies such as storm sewer separation, active real-time control and provision of adequate additional storage; and drainage system operation improvement.

With its powerful scripting language interface, ICMExchange enables users to directly import and export InfoWorks ICM data in a variety of formats (e.g., Oracle, SQL, CSV, MIF/MID, Geodatabases, Shapefiles, etc.) as well as interface with the powerful InfoWorks ICM simulation engine to create their own custom solutions. Having access to this tailored functionality right out of the box also streamlines the creation of independent applications and custom interfaces that enable users to view or modify data for evaluation and comparison of various modeling scenarios. Armed with these capabilities, consultants and utilities can now adapt the input and output from their InfoWorks ICM models to meet specific project needs in a fully automated process that increases efficiencies.

“We are committed and continue to invest in superior technology that provides our clients with a real advantage in helping them optimize and sustain their wet infrastructures,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, F.ASCE, President, COO and Chief Technical Officer of Innovyze. “We carefully listen and quickly respond to our clients´ suggestions and needs. The powerful API platformICMExchange provides is the next logical evolution in delivering a flexible and complete engineering enterprise environment that will help them drive their businesses to higher efficiency and productivity — while making their work simpler, easier and more enjoyable. Users can now design custom interfaces and tailor projects to their specific needs in new and improved ways. ICMExchange also gives them the power to make better, faster decisions in planning, designing, operating and sustaining safe and reliable drainage systems and protecting our communities and our waterways.”

Soffit Level

Soffit Level

(pipe technology) The top point of the inside open section of a pipe or box conduit.

The soffit is the highest point of the internal surface of a pipe or culvert at any cross-section. The soffit is also referred to as the pipe obvert.

So it is not quite the Crown of the Pipe.  Here is an image I found that hopefully explains it better.

Runoff from One Watershed for a 100 Year Simulation with SWMM 5 Statistics for the Subcatchment Impervious and Pervious Depth

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 Subcatchment Runoff Depth for the three types of Subcatchment Surfaces in SWMM 5:

1.       Impervious with depression storage
2.      Impervious without depression storage
3.      Pervious area with depression storage

As you can see in the graphs of depth (Figure 1) the pervious depth is often zero as the infiltration is greater than the continuous rainfall.  Of course this depends on the rainfall intensity, infiltration type and infiltration parameters.  If you perform a Statistical Analysis on the pervious depth at a saved time step of 1 hour you will find 2721 events over a threshold of 0.01 feet.

Innovyze Releases Award-Winning InfoSWMM SFEM, Breakthrough Solution for Wastewater Master Planning

Release Supports Short-Term and Long Range Evaluation and Planning Processes for Wastewater Utilities Worldwide

Broomfield, Colorado, USA, November 19, 2013

Redrawing the boundaries of wastewater collection system modeling, Innovyze, a leading global innovator of business analytics software and technologies for smart wet infrastructure, today announced the release of InfoSWMM SFEM (Sewer Flow Estimation Model). Extensively tested by the City of Los Angeles Bureau of Sanitation and winner of the City’s 2013 Quality and Productivity Improvement Award, this revolutionary dynamic sewer flow estimation software changes the way wastewater utilities around the world combine GIS data with dynamic network modeling and advanced analytics to expand and maintain large, complex and rapidly aging wastewater collection systems. Its primary strength is the ability to accurately estimate current and future sewer system flows to help users evaluate sewer system capacity and overloaded sewer mains with a high risk of collapse, and determine the condition of sewers. Armed with this information, wastewater utilities can plan improvements that mitigate or avoid adverse public health and economic impacts and keep the sewer system operating effectively well into the future, even in the face of limited budgets and growing populations.

Wastewater infrastructure in the United States is clearly aging, and capital spending is unable to keep pace with needs. There are between 700,000 and 800,000 miles of public sewer mains in the country, and capital investments in those pipes account for between 80% and 85% of all wastewater system investment requirements. Fixing and expanding the pipes will address sanitary sewer overflows, combined sewer overflows, and other pipe-related issues. The recently released ASCE 2013 Report Card for America’s Infrastructures gave the nation’s wastewater a near failing grade of D — a very slight improvement from the D minus given in the previous Report Card, issued in 2009. Yet this critical infrastructure is projected to see the largest investment gap, falling 73% short of needs. This gap will only widen with time, and addressing it will become increasingly more expensive. This state of affairs does little to assuage the public’s health and economic needs or maintain its confidence in the ecological health of the nation’s waterways, and it presents a significant challenge to wastewater utilities charged with consistently providing safe, reliable service.

An invaluable wastewater master planning tool, InfoSWMM SFEM was developed to support the short-term and long-range planning needs of wastewater utilities worldwide. The program uses census, land use and other planning data to estimate current and projected population and wastewater flows. It automatically defines tributary basins and estimates flows within the basins.

Users can then conduct several levels of planning studies to assess current sewer system capacity and future capacity needs, identify hydraulic deficiencies, and determine sound and cost-effective system improvements, flow routing, and operation plans. In addition, the model can be effectively used to identify strategic flow gauging locations, calibrate estimated flows, manage industrial discharges and perform general planning analyses.

“With powerful customer and industry-driven innovations, the new InfoSWMM SFEM meets not only utilities short-term planning needs, but also long-range master planning efforts up to a century in the future,” said J. Erick Heath, P.E., Innovyze Vice President, Director of Americas Operations. “Because it is so easy to learn and use, it will quickly transform our users’ day-to-day sewer modeling tasks and dramatically improve their workflows. Wastewater utilities can now quickly evaluate sound infrastructure improvement options far more effortlessly than ever before.”

“InfoSWMM is a standard for mainstream geocentric sewer system modeling and management,” said Paul F. Boulos, Ph.D., BCEEM, Hon.D.WRE, Dist.D.NE, F.ASCE, President, COO and Chief Technical Officer of Innovyze. “Users are continuously demanding more from their sewer modeling software, and Innovyze has again responded to their calls. We developed the most powerful and comprehensive solution available for dynamic sewer flow estimation in terms of usability, functionality and performance. InfoSWMM SFEM makes even the most sophisticated and challenging sewer system analysis fast and easy, regardless of users’ technical expertise. This effectively extends its benefits across the entire enterprise. We are very proud to offer this groundbreaking new power tool to our clients.”

How Inlets and Overland Flow Junctions work in InfoSWMM

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.
