Parametric Analysis of Concrete Gravity Dams using Finite Element Analysis
More sophisticated means of analyses have been investigated to determine the accuracy and applicability of conventional methods to a range of parameters affecting stability. This paper...

Rehabilitation Measures?Wanaque Reservoir System
The rehabilitation of Pompton Lake Dam and the dams of the Wanaque Reservoir System has provided the North Jersey District Water Supply Commission with a safe, dependable source of water...

Rehabilitation of Williams Bridge Dam
Pennsylvania Gas and Water Company initiated construction work to upgrade the 90-year old dam in order to meet current dam safety standards with emphasis on satisfying Probable Maximum...

Local Scour Under Waves Oblique to Current
Local scour around a cylindrical pile subjected to waves oblique to current was experimentally studied in a laboratory flume with a wave generator. The mode of wave-current interaction...

Hydraulic Design of Pamo Dam Spillway
The design of the emergency spillway for the San Diego County Water Authority's (SDCWA) proposed Pamo Dam is discussed. Pamo Dam is a 264-foot (80. 5 meter) high roller compacted...

Verification of a Generalized Mudflow Model
This paper presents the results from recently completed studies verifying the accuracy and applicability of a generalized one-dimensional model for dynamic routing of mudflows. Numerical...

Embankment-Dam Breach Parameters
The study used data from 43 embankment-dam failures to develop equations that predict breach formation model parameters. These data include the failure mode, embankment characteristics,...

Statistical Analysis of Embankment Dam Failures
Data on embankment dam failures in the State of Colorado were analyzed. The analyses included 1,900 dams and covered a time period from 1799 to 1985. The three basic categories of data...

Discharge and Depth Behind a Partially Breached Dam
The role that the velocity-distribution correction factor plays in the determination of the flood discharge and corresponding flow depth behind a partially breached dam is investigated....

Reinforcement of Steep Grassed Waterways
A collaborative research program has been undertaken in the UK to develop guidelines for the use of various proprietary reinforcement systems to enhance the erosion resistance of grass...

Design of Overtopping Protection for Small Dams
Many existing small embankment dams in the United States cannot safely pass current design floods without overtopping. In the past several years, embankment overtopping protection has...

Spring Creek Dam is Ready for the PMF: A Case History
Spring Creek Dam is the first earth embankment dam in Colorado, with inadequate spillway capacity, to be modified utilizing roller compacted concrete (RCC). With a structural height of...

Physical Modeling to Study the Extent of Removal of an Existing Lock and Dam on the Mississippi River
Locks and Dam No. 26 is located on the Mississippi River approximately 202. 9 river miles above the mouth of the Ohio River. This paper will discuss the utilization of a physical model...

Mechanics of Embankment Erosion During Overflow
Thousands of dams built in the United States have a potential to be overtopped by flood flows. It is necessary to understand the mechanics of embankment erosion in order to evaluate the...

Embankment Overtopping?Case Histories
Because many existing dams are subject to overtopping, there is a need to understand embankment behavior during an overtopping event. Understanding of this behavior will allow evaluation...

Vegetal Protection of Embankments and Spillways
Recent advances in the application of tractive stress to the design of grass-lined open channels are used to develop a tentative procedure for analyzing the hydraulic performance of vegetated...

Predicting and Minimizing Embankment Damage Due to Flood Overtopping
Under a contract with the Federal Highway Administration and Bureau of Reclamation, Simons, Li & Associates, Inc. (SLA) is conducting an overtopping damage study to evaluate various...

Limitations of Saint Venant Equations to Model Flood Waves
The subject of this paper is in direct contrast to all previously known research efforts. Previous effort has focused on simplified forms of Saint Venant using approximate routing models...

Improved Robustness of the NWS DAMBRK Algorithm
The combination dam breach and flood routing numerical model called DAMBRK has been developed by the National Weather Service (NWS) for forecasting river flooding events (Fread, 1984)....

Numerical Model Analysis of Sedimentation Problems at Lock and Dam 1, Red River Waterway
This paper addresses the numerical modeling techniques used to identify the conditions and parameters affecting sediment deposition at Lock and Dam 1. Two-dimensional finite element models...
