Dam Safety Quarterly
Dam Safety Quarterly


This course is currently full.

The OWRB’s Dam Safety Program will be hosting a Hydraulics Modeling Workshop in Oklahoma City on December 3, 2014. The course will cover common modeling myths, basic modeling concepts, terminology, and pre-development modeling decisions. Various types of hydraulic models, descriptions of common 1- and 2-D models, and the relative costs associated with each model type will also be introduced. Additionally, participants will be exposed to the differences in data requirements and modeling strategies between 1- and 2-D models.

The course will be led by Marc Johnson, PE, CFM, and Lee Beshoner, PE, CFM from FTN Associates, Ltd. Mr. Johnson has 35 years of experience in the development and application of 1-, 2-, and 3-dimensional hydraulic and hydrodynamic models. Mr. Beshoner has 12 years of experience in water resources engineering, including analyses with 1-D and 2-D hydraulic models and engineering design. The cost for this course is $30 and includes breakfast and lunch for attendees who reserve their seat by Monday, December 1. For more details, please contact Emma Moradi at (405) 530-8800 or emma.moradi@owrb.ok.gov.


Low Hazard Inspection Registration Open Now

The OWRB is now offering free low hazard dam inspections, including an on-site inspection, full inspection report, and a breach inundation map. Dam owners benefit from this program because state law requires them to complete a dam inspection every five years. Dam owners can also take advantage of this opportunity to learn more about the inspection and maintenance techniques in order to prolong the life of their dam and manage their liabilities as dam owners. Contact Emma Moradi at (405) 530-8800 or emma.moradi@owrb.ok.gov to register for your free inspection.


The OWRB coordinates the Oklahoma Dam Safety Program to ensure the safety of more than 4,700 dams in the state. The Program requires inspections for all jurisdictional size dams based on the presence of downstream development.

Hazard-Potential Classification Risk Involved with Dam Failure Inspection Frequency

High

probable loss of human life

annually, by a registered professional engineer

Significant

no probable loss of human life but can cause economic loss or disruption of lifeline facilities

every three years by a registered professional engineer

Low

no probable loss of human life and low economic loss

every five years


In addition, owners of high hazard dams are required to have an emergency action plan (EAP) in place. Copies of the EAP must be submitted to local law enforcement agencies and emergency management officials. OWRB staff require submittal and subsequent approval of plans and specifications prior to all new dam construction and modifications to existing dams.

EAP Workshop Wrap-Up


OWRB conducted free EAP workshops in Oklahoma City and Tulsa this July. Forty seven participants - including private dam owners, home owners associations, engineers, law and enforcement officers and emergency managers - gathered to benefit from lectures conducted by representatives from the National Weather Services (NWS), National Resource Conservation Service (NRCS) and OWRB. The workshops emphasized the importance of the EAP and its regular maintenance, defining emergency processes and related actions, roles of NRSC and NWS in improving or simplifying the emergency action plan, and reviewing OWRB rules and regulations. During the workshops, beneficial ideas were exchanged and means of communications were established amongst the attendees which could be advantageous in achieving the OWRB’s goal of keeping our state’s dams safe.

If you were unable to attend one of these workshops and would like a copy of the course materials, please email Emma Moradi.



Hydrology for Dam Safety Wrap-Up


Hydrology for Dam Safety Technical Seminar

In April, the OWRB hosted the Hydrology for Dam Safety technical seminar at the Sheraton Hotel in downtown Oklahoma City. Twenty-two engineers attended the seminar, including many from private firms as well as municipal, county, state, and federal agencies. The course, led by Dr. Baxter Vieux and Dr. Jonathan Looper, focused on the standard methods of hydrological calculations with an emphasis on applying them to dam safety studies and design. Topics included watershed characterization, developing the probable maximum storm hyetograph for a particular region, understanding appropriate applications for various routing and transform methods, and using HEC-HMS computer modeling to demonstrate hydrological principles and analysis techniques.
