Special Topics in Foundations
This book contains papers presented at a session related to various theoretical and experimental developments on foundation analysis, design and construction. The papers were written by...
Measured Performance of Shallow Foundations
The seven papers included in this book document the field performance of shallow foundations. Five of these papers present foundation settlements caused by the compression of the subsoil,...
Geotechnical Aspects of Karst Terrains
Exploration, Foundation Design and Performance, and Remedial Measures
The presence of solution cavities in karst terrains poses some unique problems in site exploration, design of foundations, and in remediation of problems with existing structures. Case...
Geosynthetics for Soil Improvement
Geosynthetics have had a tremendous impact on various aspects of soil improvement. In a number of situations which previously had not been technically or economically feasible, geosynthetics...
Evaluation Procedures for Hydrologic Safety of Dams
Procedures are proposed for selecting the safety design flood for both new and existing dams. The procedures are based on a quantitative risk assessment in which the likelihood and consequences...
Dam Seepage Analysis Using Artificial Intelligence
The paper discusses an interactive advanced decision support system (ADSS) which is being applied to analyzing seepage from embankment dams. The development of a prototype knowledge base,...
DSS: A Dam Site Selector Expert System
The Dam Site Selector (DSS) expert system is an aid for rating an area for use as a dam site and reservoir. It was developed for use in a graduate level hydrology design course at Purdue...
Kankakee Dam Discharge Characteristics
The low-head dam on the Kankakee River has flashboards which are installed as the discharge decreases in early summer, to maintain the upstream pool level. In response to concern over...
One-Dimensional Modeling of Dam-Break Flow
R.W. MacCormack method is used for the numerical integration of Saint Venant equations to simulate the propagation of one-dimensional dam-break wave. The computed water levels are compared...
Modeling of a Low Head Hydroelectric Project
In order to shorten the time to develop a hydroelectric project at the Corps of Engineers Hannibal Lock and Dam on the Ohio River for the City of New Martinsville, West Virginia, a turnkey...
Estimation of Uplift Pressure in Cracks in Concrete Gravity Dams
This paper presents an analytical solution to predict uplift pressures in cracks in concrete gravity dams. It is shown that drainage systems are effective in reducing such pressures....
Design and Performance of Earth Spillways
The U.S. Department of Agriculture's Soil Conservation Service has designed and administered construction of a large number of dams utilizing grassed earth-lined auxiliary...
Mathematical Model of Wave Induced Pressures
A two-dimensional, implicit finite difference model was built to compute surface wave induced pressures under a gravity base foundation. The results showed considerable wave attenuation...
Effect of Conowingo Dam Releases on the Water Quality of the Lower Susquehanna River
A modeling study was performed to assess the effects of flow releases from Conowingo Dam on the water quality of Conowingo Pond and the Susquehanna River downstream of the dam. Reservoir...
Silt Run Effectiveness in Withdrawing Sediment
An investigation was conducted during the silt runs on the North Platte River to determine the continued effectiveness of the runs in providing fine sediments to the canal systems downstream....
Sediment Flushing Experiences at Cherry Creek Dam
An overview of the U.S. Army Corps of Engineers, Omaha District's experiences in sediment flushing operations at Cherry Creek Reservoir near Denver, Colorado is presented....
Hydrologiic Risk Analysis for Small Dams in Missouri
A methodology is presented for calculating the risk cost for a dam based on probabilities for rainfall depth, antecedent moisture condition, rainfall time distribution, initial reservoir...
Uncertainty and Value Analysis in the Selection of Dam Modification Alternative
Objectives and attributes were decided by the dam and watershed requirements, value judgments of decision makers, quantified trade-offs between different attribute values, and technical...
Dam Safety, Yes.; But What About Safety at Dams?
Design and construction of safe structures are the professional obligations of hydraulic engineers. However, there are environmental dangers with safe structures which engineers often...
Hydrologic Safety of Earth Dams
Hydrologic and hydraulic analyses are presented pertaining to the safety evaluation of an earth dam located downstream of another smaller earth dam. The upper dam is assumed to breach...
