Stormwater Management in Kansas
This paper evaluates the current stormwater management practices of Kansas cities. This evaluation is based on a survey of all Kansas cities with populations over 10,000. Issues examined...

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...

Math Modeling of Mixing Zones in River Systems
A numerical mixing zone model was developed utilizing an implicit finite difference method with a weighted numerical scheme. The model was based on the two-dimensional advection-dispersion...

Computer Aided Drafting in the Water Resources Environment
The movement from traditional mechanical drafting to computer aided drafting in the small consulting business/research environment while necessary from the viewpoint of productivity and...

Interactive simulation of Water Resource Systems
This paper outlines some of the research currently underway at Cornell aimed at the design of an interactive simulation methododology. It describes the general approach to simulation modeling,...

Advection Calculations Using Spline Schemes
The calculation of advective transport in one and two dimensions is done by the method of characteristics using spline interpolating polynomials at the forward time step. The method has...

Use of Stochastic Hydrology in Reservoir Operation
The Bureau of Reclamation is incorporating stochastic traces to provide a broader basis for management decisions during drought periods for the Central Valley Project in California. A...

Instream Flow Needs to Protect Fishery Resources
Numerous methods have been developed over the past several decades to assess the effects of flow regulation on fishery resources and to provide a basis for the determination of suitable...

Construction of Roller-Compacted Concrete Pavement
Roller-compacted concrete pavement (RCCP) is the product of a relatively new concrete paving technology in which a zero-slump portland cement concrete mixture is spread with modified asphalt...

Project Cost Control for Heavy Equipment
Some concepts and methods of project cost control for heavy equipment have been defined, which include methods, effectiveness, outside repairs, and the resulting management information,...

Total Cost Purchase Options Buy vs Lease vs Rental Conversion Cash Flow Analysis
Today's financing alternatives are very complex and sometimes difficult to comprehend. The combined effect of the slow economy and uncertain future workload has accelerated...

Alternative Methods for Payment of Construction Equipment Ownership Costs on Federally Funded Projects
Construction equipment investment is a significant portion of the capital investment for contractors specializing in heavy construction. Operating this equipment under the changes clause...

Earthwork and Resource Estimation on Large Expedient Projects
A computer-aided technique is being developed for planning, design, estimating, and scheduling of horizontal construction for facilities required to support military operations. This technique...

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...

Application of the BEM to Elastodynamics in a Three Dimmensional Half Space
The boundary integral equations (BIEs) are formulated for scattering problems of elastic waves by a cavity or a crack in a three dimensional half space. Two formulations based on the Green's...

Explicit Integration of Boundary Integral Equations in the Frequency Domain for Wave Scattering Problems
The goals of this article are: (1) to present an efficient method for the integration of the boundary integral equations for wave scattering problems and (2) to apply this method to the...

A BEM-Perturbation Technique for Membrane Structures
Most of the previous work has concentrated on the free vibration problem. The present paper examines the problem of low frequency forced vibrations of a membrane due to an oscillatory,...

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...
