Highway Erosion Remedial Measures
Soil erosion from highway ditches, cut slopes and fill slopes present a continuous problem to roadway designers, geotechnical engineers, and construction and maintenance personnel from...

A Method to Treat Incident Wave Condition in Shallow Water Equation
A method to consider open boundary condition of the shallow water equation to analyze water surface wave and tide is employed in the finite element anaysis. This can be done by considering...

Weighted Finite Difference Method for Diffusive Transport
The purpose of the paper is to present an application of a new method to the two-dimensional, transient advective-diffusive transport in both turbulent flow of viscous fluid and seepage...

A Finite Element Application of Sand Terrace Formation Process
In this paper, the formation process of a sand terrace in front of river mouth is simulated numerically by means of the finite element method. The two-step explicit scheme is applied as...

Suspended Sediment Model of Offshore Tin Mining
The three dimensional dispersion equation is integrated vertically to use in describing the suspension of silt from offshore tin mining. The resulting two dimensional equation includes...

STUDH: A Two-Dimensional Numerical Model for Sediment Transport
TABS-2 water level and flow computations are performed by the generalized numerical model program RMA-2V; salinity and tracer transport computations are performed with RMA-4, and sediment...

Cold Regions Engineering
This volume contains papers that were presented at the 5th International Cold Regions Engineering Specialty Conference, sponsored by ASCE and held in St. Paul, Minnesota, February 6-8,...

Boundary Element Methods in Structural Analysis
Tutorial and state-of-art aspects of the Boundary Element Method (BEM) are combined with applications in structural analysis in order to provide information about the advantages of this...

Implementation of FEMA Guidelines on Alluvial Fans
This paper provides a general basis for analysis and mapping of flood hazards on alluvial fans. Federal Emergency Management Administration (FEMA) alluvial fan methodology is discussed...

Cross Sectional Area Reduction Floodway Method
Encroachment on the floodplain, such as structures and fill, reduces the stream's flood carrying capacity, increases the flood heights and velocities, and increases flood...

Water Quality Monitoring of Highway Construction
The primary objective of water quality monitoring, as it relates to highway construction, is to obtain quantitative information to ensure that runoff from the construction site does not...

Estuarine Mud Flow Modeling
This paper presents a model for the simulation of selective withdrawal of estuarine mud. This research is part of the investigation of the design of a mud pumping plant as an alternative...

Numerical Modeling of Hydraulic Jump
Boussinesq equations describing one-dimensional unsteady, rapidly varied flows are numerically integrated by using a second-order and a fourth-order accurate explicit finite-difference...

General Formulation of Best Hydraulic Channel Section
The best hydraulic channel section is determined by using Lagrange's method of undetermined multipliers. The approach presented is more general & easier to apply than...

Regionalization of Flood Characteristics
Regionalization procedures are used to transfer flood characteristics from gaged to ungaged locations. These procedures are an extension of the gaging network that allows planners and...

Groundwater Monitoring Network Design Using Coupled Monte Carlo Simulation and Optimization
This paper presents a method for the design, under uncertainty, of a groundwater well network for compliance monitoring at a waste disposal site. A numerical model of contaminant transport...

Verification of Local Modes in a Two-Dimensional Tidal Model
Based on a generalized model equation, a two-dimensional hybrid finite element model has been developed to study tidal waves of incompressible, homogeneous fluid in rotational flows. In...

Design, Construction and Testing of Repairs to the Low Level Outlets at Terzaghi Dam
Operation of the low level outlets (LLOs) at Terzaghi Dam in southwestern British Columbia resulted in severe cavitation at operating heads significantly lower than design. Modifications...

Prediction Using Geostatistics and Mathematical Models
This paper discusses a new interpretation of geostatistical estimation and presents some thoughts on the meaning of probabilities in geostatistics and the role of mathematical models of...

Redundancy and Reliability of Water Distribution Networks: An Entropy Based Approach
Based on the concepts of entropy and graph theory, a functional form is developed as a quantitative measure for redundancy in water distribution networks. This function was obtained by...
