Numerical Simulation of the Bed Armoring Process
The stability of a river channel depends to a great extent on sediment characteristics. If the amount of sediment coming into a given reach for some reason becomes less than the river's...
A Nebraska Power District's Experience in Stabilizing by Silt Injection
The structures, rolled earth and concrete, of the Central Nebraska Project are constructed on foundations of loessial soils that range from a few feet to more than 100 feet in depth. The...
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...
Modeling Multiple Spur Schemes to Control Bank Erosion
A natural consequence of the meandering tendencies characteristic of all streams, is streambank erosion. The problem has taken on particular interest recently, focusing on erosion problems...
Willamette River Adjustments to New Spur Dikes
Severe bank erosion has caused recent local losses of up to 30 ft (9 m) per year of prime agricultural land along a half-mile (800 m) reach of the Willamette River, Oregon. The U. S. Army...
Passive-Intake System for a Shallow Sand-Bed River
The Jeffrey Energy Center draws its cooling water make-up from the Kansas River near Belvue, Kansas. At this site, the Kansas River is a shallow sand-bed river of constantly changing bottom...
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....
Flood Travel Time
The effects of infiltration on the flood travel time are investigated. In flood prediction, the physical domain for flood cumulation is expressed by the period of time for water to travel...
Riprap Sizing-Four Methods
A comparison summary is provided for sizing of riprap by four methods: Isbash, Froude, Tractive Force - Logarithmic Velocity Profile (TFL), and Tractive Force - Power Velocity Profile...
Simple Hydrologic Modeling
Several simple models for estimating precipitation and evapotranspiration from a limited data base are discussed. Rainfall probabilities may be calculated from mean monthly rainfall. Depth-duration-frequencies...
Hydraulics and Hydrology of Border Irrigation
Proper description of the hydraulics of irrigation of farmland is necessary in management. Many descriptions of furrow or border irrigation are not adequate to describe truly physically...
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...
Assessing Irrigation Impact on Instream Flow
A hydrologic model to help river system managers determines the demand for irrigation water in a two mile wide strip of land along the river using information which is generally available...
SCS Water Supply Forecasting Opportunities
SCS personnel have been surveying the mountain snowpack, collecting other hydrometeorological data, and providing water supply forecasts to users for nearly 50 years. Recently, the snow...
Modifications of Dams for Recreational Boating
Many existing dams and river structures require modification, and new structures may need to include designs to allow safe white water activities. The basic problem is safety, with a long...
Pipeline Materials and Design
The proper use of pipeline materials and design is obviously paramount in the private and public works sectors. The introduction and proper use of new piping materials and design procedures...
Sedimentation Consolidation Models?Predictions and Validation
In very soft sediments, questions have arisen concerning the capability of standard computational techniques used to implement calculations. The problems mainly lie in the manner in which...
Holland's Fight Against the Sea
The Netherlands have always been threatened by the sea, its Delta Region most of all. After the catastrophic floods of 1953, the Delta Plan for the strengthening of coastal defenses and...
Land Treatment of Hazardous Waste
Land treatment is one of several available alternatives to the use of landfills and surface impoundments for the treatment and disposal of hazardous waste. Using this technique, hazardous...
Seismic Design of Embankments and Caverns
The papers included in this publication were presented at three symposia on seismicity and seismic design for embankment dams and underground openings. Primary topics for discussion include:...
