How much water is your utility losing to leakage, customer meter error or water theft?How can your utility determine the cost of uncaptured revenue from non-revenue water (NRW)?A number of US regions now have state or regional agency water auditing requirements in place. Unfortunately, most agencies with a water audit requirement do not provide a means for comprehensive training of water utility personnel. This seminar will help utilities esta...

Course Objectives Important aspects of dam safety are the design and construction of the dam, levee and appurtenant structures. The basis for dam and levee safety is established in the development of the detailed design drawings and project specifications, and implemented in construction of the project. Technical reviewers have the important role of checking to verify if the design meets the requirements and criteria that have been developed b...

The USACE has been conducting economic risk analyses for evaluating benefit cost ratios for levee projects since the 1960s. With a new focus on life safety, these same analytical techniques are now being used to evaluate priorities for infrastructure investments and required design reliability to achieve various goals, including National Economic Development and life safety risk reduction. This webinar will look at how the USACE is integratin...

This webinar will review the current state of the practice for rehabilitation of embankment dams to address seepage issues. Seepage rehabilitation measures can generally be grouped into two categories: seepage reduction / limitation measures and seepage collection measures. Seepage reduction / limitation measures include such features as foundation grout curtains, low permeability blankets, and seepage barrier walls. These measures are intend...

Recent improvements in the computational capacity of computers and in the availability of high-quality terrain data have allowed 2D hydraulic models to become highly valuable tools in dam and levee safety analyses. Today, there are several free and commercially-available 2D models on the market. This webinar will provide a background on 2D hydraulic modeling theory, identify steps to set up a 2D model, describe important specifications for 2D...

Inadequate spillway capacity, significant hydrologic loadings on embankments and structures, and operation and maintenance are common dam safety issues, instigating the need for risk-reduction measures and/or rehabilitation. 3D weirs, or weirs with a crest length greater than the spillway width, are a particularly efficient approach to reduce these concerns. These weirs are also commonly used in new dams and may be useful as levee spillways. I...

During the last 10 years, there have been unparalleled levels of activity in dam and levee foundation remediation. This has been triggered mainly by the U.S. Army Corps of Engineers’ evaluation of their dam and levee portfolio following the disastrous flooding of New Orleans and surrounding areas in 2005. Remedial diaphragms walls have been in installed in dams in the US since 1975 when Wolf Creek Dam, in Kentucky, was repaired for the...

Dam failures typically result from interactions of human and physical factors which extend over years or decades. Understandably, engineers and others involved with dams normally focus on the physical factors. However, because physical systems such as dams are subject to physical laws and do not make ‘mistakes’, it may be asserted that dam failures (and incidents) are fundamentally due to human factors. The other side of this coin...

The field of hydrology experienced its most dramatic period of development from the late 19th century to the mid-20th century. While the theory and equations used to estimate watershed runoff have remained relatively unchanged since that time, the availability of Geographic Information Systems (GIS) software and geospatial data has modernized the methods used to evaluate watershed characteristics and develop input parameters. Today’s hy...
