Floodplain Mapping Using HEC-GeoRAS and RAS Mapper
*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch
Purpose and Background
HEC-GeoRAS is an ArcGIS toolbar that helps to incorporate LiDAR and other topographic datasets in to HEC-RAS. This webinar will demonstrate how to easily add topographic data to a HEC-RAS model once the HEC-RAS model has been run, and how to map the resulting floodplain using both HEC-GeoRAS and the new HEC-RAS tool, RAS Mapper.

Dynamically Loaded Machine and Equipment Foundations - A Design Primer
*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch
Machinery and equipment typically found in industrial and process facilities often exert dynamic loads on their foundations. Designing these foundations is quite complicated, much more so than the design of the foundations that support buildings and statically loaded equipment. (The latter is addressed in the companion ASCE webinar, Design of Foundations for Equipment Supports.) This topic is rarely, if ever, included in the engineering college curricula, and the engineers are left to learn on the job. Yet the stakes are high: The failure of an incorrectly designed machine foundation can lead to damaged equipment and to expensive downtime. This webinar provides a practical introduction to the complex issues of designing dynamically loaded machine and equipment foundations.
Purpose and Background
Many engineering firms that specialize in the design of industrial facilities and heavy-equipment foundations have developed a wealth of in-house design standards, but this information is not available to others. As a result, and because of the design complexity involving dynamic analysis and specialized software, some engineers have resorted to simplistic rules-of-thumb without understanding the limitations of such shortcuts.
Calculation and Use of Time of Concentration
*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch
Purpose and Background
Time of concentration is a frequently overlooked parameter in urban drainage design. It is often calculated using one of several common equations that are selected based on user familiarity rather than on the characteristics of the drainage basin. Time of concentration can also be calculated incorrectly when the emphasis is placed on finding the longest flow path, which often is not appropriate when used to determine peak flows. This webinar will cover the Kirby-Hathaway Equation; the Kirpich Equation; the FAA Equation; the SCS Method for computing time of concentration; as well as a solution using the physical concepts of sheet flow, shallow concentrated flow, and open channel flow. The webinar will include examples of the different equations and a discussion on when the use of each equation is appropriate. It will also include a discussion on requirements for time of concentration calculations in stormwater design manuals.

Sustainable Transformation/Rehabilitation of an Urban Corridor
*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch
Purpose and Background
During the past 50 years, roadway infrastructure in the urban environment has been focused on moving vehicles as quickly as possible from one place to another – generally into the city in the morning and to the suburbs in the evening. As urban living becomes more popular and dependence on the automobile becomes less desirable, city officials are looking at ways to transform roadway corridors into comprehensive transportation networks. This hierarchical network needs to function efficiently to support the movement of people and goods, as well as benefit the communities in which they are located. This webinar will show various challenges and solutions addressed in a rehabilitation infrastructure project in Washington DC – the Rehabilitation of H Street NE.

Engineers Week Luncheon
Join us in celebrating the engineers that make the world a better place.
Topic: Engineering New Horizons: Honda and The Power of dreams
Speaker: Clement D’Souza, Engineering Large Project Leader, Honda of America Mfg., Inc.
Clement D’Souza is an engineering large project leader at Honda of America Mfg. currently assigned to the New Model Group for the Acura NSX and the startup of the new Performance Manufacturing Center.
Clement will talk about his experiences working with Honda, in particular,
- Good engineering starts with the willingness, ability, and empowerment to dream. At Honda we believe that dreaming big is the key to success.
- Clement will share what he has learned since he started at Honda, how the challenges he faced in launching mass production products prepared him for the biggest challenge of his professional career - developing a state-of-the-art manufacturing facility that will build the first-ever produced super sportscar in the United States.
- As the production leader for the NSX project, Clement will explain the thrill in creating an all-new plant to build an all-new super sports car. He will talk about the focus of him and his team on creating a plant that has the perfect synergy between man and machine.
January Luncheon Meeting
Topic: EWB Update - Flood mitigation project in the Esfuerzo de Paraiso, Dominican Republic
(Online registration and payment available, see bottom of page.)
This presentation will be on the Central Ohio Professional chapter of Engineers Without Borders USA. The guiding principles of EWB are based upon sustainability and community ownership and involvement. The implementation of these philosophies will be reviewed through a case study of two projects undertaken by the Central Ohio chapter of EWB. The first project is a municipal roadway project in the Las Pilitas neighborhood of San Pedro Puxtla, El Salvador. The project constructed a 400 foot long street and drainage system for an isolated residential area at the edge of the village of San Pedro Puxtla. The street, which is now complete, connects the Las Pilitas neighborhood to the rest of the town, eliminates unhealthful exposure to contaminated drainage, and allows safer access to the residences in the rainy season. The project was named the 2014 project of the year by EWB-USA. The second project is a flood mitigation project in the Esfuerzo de Paraiso neighborhood of Santo Domingo Norte, Dominican Republic. The Esfuerzo de Paraiso neighborhood, located within a floodplain, bounded by the Yaguaza river to the west and an agricultural canal to the east, experiences frequent and severe flooding. The residents experience near weekly flooding during the rainy season (April through October) with flood water reaching as high as 10+ feet during hurricane level events. The floodwaters also carry contaminants from nearby trash dumping piles and restrict access from the neighborhood to the surrounding city. The Central Ohio Professionals chapter is currently teamed with the OSU student chapter in the assessment phase of this project.
Design of Foundations for Equipment Support
*Open only to Central Ohio Section Members
*Seating is limited to the first 25 people
*Bring your own lunch
Purpose and Background
Design of foundations for equipment support is often required in industrial and process facilities, yet this topic is rarely, if ever, included in the engineering college curricula. Engineers are left to learn on the job – a process that often produces a variability of foundation designs for similar installations. In some cases the design is performed by the engineers who may or may not even have structural background. Yet whenever any component of an equipment foundation fails, the resulting strengthening and retrofit activities are often very expensive and intrusive into the equipment operations.
