Use of Database in Geo-environmental Engineering
Geo-environmental projects are becoming increasingly complex requiring rigorous mathematical computation and analysis of large amounts of data. This paper looks into how a geo-environmental...

A Simplified Method of Multistory-frame Analysis Including the P-Δ Effect
A simplified method of non-iterative analysis of rigid multistory-frames having vertical columns with different heights within the same story is developed by means of a modification to...

Practical Solution of the Flexibility to Stiffness Transformation Problem With a Mathematical Assistant for the Personal Computer
This paper will show how a relatively complicated structural mechanics problem can be solved easily with a symbolic manipulation program. Specifically, the authors will demonstrate how...

Application of the Phase Change Process to One-Dimensinal Consolidation Behavior of Peat
In this study, based on the fact that the pore of fibrous peat consists of the macro (outer) pore between organic matters and the micro (inner) pore inside organic matter, an approximate...

Finite Strain Consolidation for Vertical Drains
Consolidation equations for vertical prefabricated drains which consider finite vertical strain of the soil are derived. Estimated consolidation times are shorter when finite soil strain...

Probabilistic Observation Method for Settlement-Based Design of a Landfill Cover
Uncertainties in subsurface conditions make predicting total and differential settlement a difficult task. The Observation Method, which is commonly implemented to acquire additional knowledge...

Reliability-Based Assessment of Corps Structures
Due to the limited amount of funding available for maintenance, rehabilitation, and replacement of aging Corps structures, the director of civil works, Headquarters, U.S. Army Corps of...

Uncertainty and Time Preference in Shore Protection
From a review of economic, psychologic, and geographic literature, three points of criticism of the economic model of choice are 1) when faced with losses, individuals tend not to be averse...

Subjective De-Biasing of Data Sets: A Bayesian Approach
In this paper, we examine the relevance of data sets (for instance, of past incidents) for risk management decisions when there are reasons to believe that all types of incidents have...

Developments in Risk Analysis Commercial Software
There has been a marked increase in the number and type of commercial software packages available to support risk and uncertainty analysis. Monte Carlo simulations, the first such tool,...

Federal Risk Management Policy: Where Is the Federal Government Heading? Where Are the Problems?
The paper summarizes the first session of the conference which discussed the present state and problems of federal risk management policy. Topics discussed include efficacy of models on...

Behavioral, Social, and Institutional Aspects of Risk Analysis
The paper summarizes the third session of the conference which discussed four items that become pitfalls for decision makers when neglected. These are parameter uncertainties as distinct...

Risk Management Strategies for Natural, Manmade, and Technological Hazards
The paper summarizes the fourth session of the conference which discussed risk assessment approaches in bio/chemical hazards; specific studies on people's behavior and views of natural...

Immobilization of Heavy Metals in Cementitious Matrix

Recovery of Chromium from Spent Plating Solutions by a Chromyl Chloride Process
A novel chromyl chloride process has been investigated for the recovery of hexavalent chromium from spent plating solutions. In this process chromium is converted to chromyl chloride by...

NCASI Experiment Related to Validation of Equilibrium Partitioning (EP) Theory
A review of NCASI's technical studies related to evaluating equilibrium partitioning (EP) theory as it is commonly applied in regulatory setting is presented. Although interim results...

Combining a 2-D Flood Plain Model with GIS for Flood Delineation and Damage Assessment
This paper describes potential applications of Geographical Information System (GIS) for flood hazard delineation and damage assessment. The hydraulic model simulates both 1-D flood routing...

Object-Oriented Finite Volume Dam-Break Model
This paper is devoted to Object-Oriented analysis and design techniques to two computational modules in the field of dam-breaking. The C++ Object-Oriented...

Two-Dimensional Modelling of Flow in the River Sava
On the river Sava near Ljubljana, a sports centre with a kayak racing channel was built in 1948. For the world championship in kayak-canoe racing in 1990 totally new racing channel had...

Is Bedform Development Chaotic?
A qualitative analysis of a model for the partially specified bedform development system is presented. The study rests on the use of technique of loop analysis and the connection of the...
