Risk Analysis in Water Quality Control
Design of facilities for the control of water quality is usually predicated upon some explicit expectation of performance. In reality, unit operation efficiency, system operation, model...
Hydraulic Uncertainty in Risk Analysis
Considerable effort has been expended in defining and evaluating hydrologic uncertainties; however, the analysis and evaluation of hydraulic uncertainties has received little attention....
Risk Analysis in Dam Safety Programs
There are about 68,000 dams in the Nation. About 95 percent of the dams are nonfederal; the balance are owned by various agencies of the federal government. Over 30 percent of the high...
Sedimentation Study for the Rochester, Minnesota, Flood-Control Project
In a cooperative effort, the U. S. Army Engineer District, St. Paul (NCS), and the Soil Conservation Service (SCS) planned a combined flood-control project. The SCS portion of the project...
Analysis of Partially Filled Circular Storm Sewers
The classic design approach uses Manning's formula. Comparisons between analytical results obtained in this manner and the many available experimental results indicate substantial...
The Design and Construction of the Bartletts Ferry Labyrinth Weir Spillway
The discharge capacity of the Bartletts Ferry Project has been increased 165 percent by the addition of a labyrinth weir spillway. The hydraulic design was based on a published design...
Hydrotest Rupture of Penstuck Liner at Bath County
Bath County is the construction site of Virginia Electric and Power Company's pumped storage project. Rupture of a penstock liner during hydrotest at high pressure threatened...
Valuable Design Insights Derived from Construction and Operation of Kinzua Dam
A number of design alternatives have surfaced during more than 17 years of operating experience at Kinzua Dam which should be useful in the design, construction, and operation of other...
Flow and Scour Patterns around Gabion Structures
There is a need for simple, inexpensive and effective means for streambank protection and fish habitat enhancement. Initial results are presented of laboratory research on the performance...
Local Scour at Fish Rocks
There is a growing interest in the enhancement of rearing habitat for juvenile anadromous fish in the Pacific Northwest. This has focused attention on the need for a better understanding...
Operating Experience--Fine-Mesh Traveling Screens
Start-up and operating results for a new screenhouse at the Prairie Island Nuclear Generating Plant, 50 miles (80 km) downstream from Minneapolis/St. Paul, are compared to design assumptions....
Report on Task Committee's Scope and Findings
A Task Committee for the Design of Outlet Control structures studied the state-of-the-art practices concerning the hydraulic function, water quality, public safety, maintenance and aesthetic...
Safety, Maintenance, and Aesthetic Considerations Associated with Outlet Control Structures for Stormwater Detention Ponds
Findings of the Task Committee for the Design of Outlet Control Structures, an ASCE Technical Committee, regarding maintenance, safety and aesthetic considerations for stormwater detention...
Design Accuracy of Stormwater Detention Basins
While the stormwater detention basin is the most frequently used method for controlling runoff from developing areas in the United States, there appears to be no statement of the probable...
Evaluation of Two-Stage Outlet Hydraulics
A two-stage detention basin is an effective storm water management tool. This type of basin is designed to control two storm events and it will tend to perform better than a single-stage...
Detention Pond Outlet Design for Pollution Control
Stormwater runoff detention ponds were originally developed for the control of flooding and the designs of the outlet control structure must be modified to obtain pollution control objectives....
Reservoir System Management for Water Quality
A reservoir system analysis computer model has been recently developed with the capability to simulate up to 10 reservoirs, 30 control points and 8 water quality parameters. With this...
Physical Hydraulic Modeling for a Small Hydroelectric Redevelopment
In the development of a small hydroelectric project, the operating head on the plant is usually limited. On these projects, the need to minimize head losses and eliminating other factors...
Realistic Hydrology for Basin Management
Several realistic yet simple methods to describe infiltration, soil moisture redistribution, aquifer recharge, canal seepage and stream-aquifer interaction in a river basin are presented...
Modeling Analysis for Management of Artificial Recharge
The objective of these groundwater and sediment modeling studies is to determine the net change in storage and potentiometric levels within the Bunker Hill Groundwater Basin resulting...
