Relative Landslide Susceptibility in Davis County, Utah?A Multivariate Approach
The complex distribution of soil properties makes prediction of slope stability extremely difficult in these mountain watersheds. The need to assess these watersheds for their susceptibility...

Generalized Methodology for Simulating Mudflows
In this paper, a one-dimensional dynamic flood-routing model, for non-Newtonian fluid properties, is described and applied to two different mudflow events: Holbrook Canyon, Utah, and Mount...

Parameter Optimization of Dynamic Routing Models
The methodology utilizes approximate cross-sectional properties represented by separate power functions for channel and floodplain, and a very efficient optimization algorithm for determining...

Making Water System Rehabilitation Decisions
Making decisions regarding water distribution systems has always involved a great deal of judgment due to the complexity of the decisions involved. This paper presents a framework for...

Optimization, Simulation and Multiobjective Analysis of Operating Rules for Reservoir Systems
In this paper, three steps are proposed for establishing reservoir operating rules which can be used in real-time without flow forecasting. In the first step, optimization models are used...

Water Resources Systems Planning: Differential Dynamic Programming Models
A Monte Carlo optimization methodology is presented for water resources systems. The planning model define the optimal storage and release policies for the reservoir system. The optimization...

Model for Optimal-Risk Based Water Distribution Network Design
Various models using a variety of optimization techniques were developed for determining pipe diameters, network layout, pump capacities, and other design parameters. The objective function...

The Effect of Storms on Pollution Loading Estimates
A rather extensive field and modeling program is underway in the Sandusky Bay/Nearshore region of Lake Erie and the objective of this paper is to summarize the preliminary results of a...

Traveling Trickler Center Pivot Design
There have been a number of proposals to improve the center pivot irrigation system in order to overcome the inherent inefficiency from high evaporation losses and energy requirements....

Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...

Grand Canyon Water Line by Directional Drilling
The South Rim Village at Grand Canyon National Park obtains its water supply from a point called Roaring Springs which is located approximately 15 miles across the Canyon on the North...

In-Situ Microocosms for Calibrating Dynamic Models
The calibration of dynamic water quality models for lakes and reservoirs requires significant quantities of data, experience, and judgement. In particular, the identification of an appropriate...

Analysis of Freshwater Distribution System at the Long Beach Naval Complex
This account of the evaluation of freshwater pipelines at California's Long Beach Naval Complex discusses current methods for assessing the condition of damaged water lines....

The Past, Present & Future of Earthmoving Scrapers
This paper is a summary of the history and development and use of earthmoving scrapers. It will also take a look at the future of this type of machine. We'll build the discussion...

Rapid Assessment of Seismic Vulnerability
The choice of a seismic damage assessment method depends fundamentally on how the assessment will be used, but always involves definition of the expected ground motion and the structure...

ATC Methodology and Data for Rapid Assessment of Seismic Vulnerability
Recently developed Applied Technology Council (ATC) methodology and data provide a technical basis for rapid assessment of structure seismic vulnerability. Methodology developed under...

Use of In Situ Tests in Geotechnical Engineering
In the past ten years, many new types of in situ test equipment and many new techniques have been developed. The papers in this volume are concerned with applications of in situ measurement...

Nonlinear Quasi-Static and Transient Response Analysis of Shallow Shells: Formulations and Interior/Boundary Element Algorithms
Nonlinear integral equations are derived for the representation of displacements of shallow shells undergoing moderately large, quasi-static or dynamic deformations. A combined interior/boundary...

Seismic Response of Pipes Supported on Complex Frames
Analytical approaches and modeling techniques used to calculate seismic responses of piping systems, supported on complex open-frame structures, are evaluated. Seismic responses are obtained...

Offshore Platforms Subjected to Wave Forces
The dynamic analyses of offshore platforms are mostly based on the lumped mass matrix method in the frequency domain. Although the approximations involved in the lumped mass matrix method...
