(RSVP only | Lunch on own)

7.0 PDHs (due to hour lunch break)

The Sustainability, Resilience, and Project-governance requirements depend on effective environmental permitting. Environmental permitting encompasses accomplishing on air quality, water quality, effective waste handling and disposal, and protection of the soil-environment. The US has the proven legislation, regulation, and underlying policies for effective environmental permitting, via (not-limited-to) the National Environmental Policy Act (NEPA), clean air act (CAA), clean water act (CWA), Resource Conservation and Recovery Act (RCRA), Comprehensive Environmental Response, Compensation, and Liability Act (CERCLA), and Emergency Planning and Community Right-to-Know Act (EPCRA).

The continual-learning on environmental regulatory requirements including the permitting processes would help support on the sustainability, resilience, and project-governance needs of the hour. This workshop topics will comprehensively include, as follows: air permitting; water-withdrawal approval(s); public water systems (PWSs); municipal and industrial wastewater – National Pollutant Discharge Elimination System (NPDES) and Local permitting; stormwater or wet-weather flow(s) permitting; solid and hazardous waste handling and disposal; oil/chemical and other storage tanks; spill prevention; and, environmental compliance.

The workshop will benefit environmental engineers, scientists, and associated professionals towards leadership on environmental permitting.

Technical Workshop: How to Build Reliability in the Results of Numerical Modeling 

Sunday, May 19, 2024 | 8:00 am – 5:00 pm

(RSVP only | Lunch on own)

7.0 PDHs (due to hour lunch break)

Engineering designs and assessments in water and environmental projects are increasingly relying on computational models as an alternative, or supplement, to experimentation. Verification and validation (V&V) and uncertainty quantification (UQ) techniques constitute a set of tools to provide quantitative insight into the reliability of those developed computational models.

This workshop is designed to give the audience a broad view and hands-on experience of V&V and UQ in the context of numerical modeling in water and environmental engineering.

An in-depth introduction to the fundamentals of verification procedures in scientific-computing is the first part of the course. Techniques for validation of models based on measurements and validation experiment design are discussed next. Then, a brief review of techniques for the quantification of uncertainty due to model, numerical techniques and parameters is presented.

The workshop concludes with the emerging techniques of SQA for computational modeling such as “literate programming”, “automation of documentation”, “version control systems”, “reproducibility” etc.

Technical Workshop: Professional Ethics - Introduction and Review

Sunday, May 19, 2024 | 12:00 pm – 1:00 pm

(Lunch on own)

1.0 PDH

Observation of professional-ethics has become critical more than ever to professionals accomplishing various day-to-day tasks. Updates to the principles or canons of professional-ethics are ongoing as put forward by various professions. The requirements of ethics have been put into practice since the BCE; at the core, the answers to what are ethics?, what is a gift?, what is a profession?, and who is a professional?, need to be well implanted into the professional practice. The “character, competence, and commitment” in a professional have clearly been identified and practiced by the US Army. Various professionals are identified and have applicable requirements under the code of federal regulations (CFR).

In our Engineering profession, we observe the requirements of professional-ethics and periodically obtain training to fine-tune our knowledge. The American Society of Civil Engineers (ASCE) has updated the ethical responsibilities for its members to observe on (in the order): society; natural and built environment; profession; clients and employers; and, peers. The environmental, health, safety, and security (EHSS) professionals observe professional-ethics in working with multifaceted professional-entities.

This presentation includes: professional-ethics as stipulated by various (selected) professional societies, institutions, and organizations; requirements of professional-ethics to professional engineers (PEs) in the State of Wisconsin (WI USA); and, a discussion of ethical-situation(s) (to the extent feasible). Thus, a comprehensive review on professional-ethics would be conducted towards a good-guidance to the engineering professionals.

Launched in 2016, the National Center for Computational Hydroscience and Engineering (NCCHE) at the University of Mississippi has been developing and operating the Decision Support System for Water Infrastructural Security (DSS-WISE) Web.  Through this free web-based tool, more than 1,800 dam safety professionals have submitted over 68,000 dam-break flood inundation modeling scenarios from across the United States and Puerto Rico.  

Researchers at NCCHE have produced numerous developments and improvements to the system to increase the capability, ease of use, and speed for its users.  In November of 2021, the DSS-WISE Web development team celebrated the release of Version 3.0, which brought a complete overhaul of the simulation setup and data entry Viewer portal among its new features.

To help new and existing users understand these new capabilities and receive the maximum benefits from the system, a half-day short course will be presented as a conference specialty workshop.  

The topics for this course are:

•    Introduction/Overview of DSS-WISE Web
•    Simulation Scenario Setup Research and Data Entry
•    Understanding Simulation Outputs
•    Hands on Exercises Using the New System Features
•    Tips and Tricks/Advanced Techniques
•    Future System Enhancements

The Storm Water Management Model (SWMM) is used throughout the world for planning, analysis, and design related to stormwater runoff, combined and sanitary sewers, and other drainage systems.  SWMM predicts runoff quantity and quality from drainage systems, and is used by communities, consulting engineers, and many EWRI members as part of their innovative research.  

This workshop will gather SWMM developers - including the Center for Infrastructure Modeling and Management, Inc. (CIMM) who recently completed SWMM 5+, the U.S. Environmental Protection Agency, private sector companies, and others – SWMM users from academia, government, and the private sector, as well as others who are invested in the future of SWMM.

The purpose of the workshop will be to share information about recent improvements to SWMM, discuss future needs for SWMM including in the areas of flood modeling and real-time digital applications, consider options for the ongoing maintenance and development of SWMM, and build the community of SWMM stakeholders.  

This workshop will also report out on what has been accomplished since the 2018 SWMM Visioning Summit sponsored by EWRI, NCIMM, and EPA in Reston, VA.    

Technical Workshop: Water Hammer in Water Systems:  Analysis and Mitigation with Hands-On Training

Tuesday, May 21, 2024 | 1:00 pm – 4:30 pm


(RSVP only)

Laptops Required for Participation

3.5 PDHs 

Hydraulic transients, commonly known as water hammer, pose a serious threat to water systems, as they can cause catastrophic failures such as pipe bursts and significant damage to pumps and valves.  Simulating hydraulic transients remains challenging due to the nonlinearity of governing equations, the uniqueness of every water system, and the dynamics of system operation.

This workshop will introduce the fundamentals of hydraulic transients in laymen's terms and the two widely used numerical methods of Method of Characteristics (MoC) and Wave Characteristic Method (WCM) in terms of their benefits and applicability.  It will also detail a typical procedure to build a well-represented transient simulation model and cover some common pitfalls along with it.  Surge protection strategies will be evaluated for both existing and new water systems.  Each surge protection device type will be discussed from the perspective of applicability.  

In the final section, the participants will use InfoSurge Pro, an extension of InfoWater Pro, to go through some well-designed hands-on exercises and, as a result, gain the capability to deliver a transient modeling project with great confidence. 

Technical Workshop: Two-Dimensional Modeling of Structures for Detailed Hydraulic and Sediment Transport Analyses

Wednesday, May 22, 2024 | 3:00 pm – 6:15 pm

(RSVP only)

3.5 PDHs 

Over the past ten years the application of two-dimensional (2D) numerical model techniques for simulation of hydraulic conditions in rivers, floodplains, reservoirs and estuaries has become much more commonplace. The numerical engines SRH-2D (USBR) and HEC-RAS 2D (USACE) specifically, have seen widespread application.

As the community has become more aware of the capabilities of these engines, additional applications and tools have continued to evolve.  With more and more new, or less experienced users engaging in developing 2D hydraulic models, it is important to emphasize the different modeling approaches and methods that are used for different applications.  

Therefore, this workshop will focus on 2D model development for the analysis of detailed hydraulics and sediment transport through structures, including bridges, culverts, weirs, and other natural instream structures (i.e., engineered log jams).  

Best modeling practices for detailed hydraulic structure analyses will be illustrated using the SRH-2D engine with the Surface-water Modeling System (SMS) interface, but they apply to other model engines as well.  Key topics will include mesh generation for representation of culvert and bridge structures, specification of model parameters for various structures, extracting hydraulic parameters for bridge scour evaluation, and evaluating sediment transport through structures. An overall review of best modeling practices and model review will also be included.
