A Linear Dynamic Programming Model for the Optimal Allocation of Water in Groundwater Dependent Areas
The purpose of this paper is to describe an efficient computer-aided planning method using linear and dynamic programming together with a finite difference groundwater model to determine...
Adsorption, Desorption and Transport of Pesticides in Groundwater: A Critical Review
Adsorption and desorption are major mechanisms affecting the transport and fate of pesticides in groundwater. Equilibrium, chemical nonequilibrium and physical nonequilibrium adsorption...
An Inline Retarding Basin
This paper discusses the idea of retarding flows within existing right-of-way in a linear basin. This concept is based on longitudinally dividing the right-of-way into two sections. The...
Stochastic Streamflow Sequences for Reservoir Operation and Design
A stochastic streamflow model is adapted for risk methodology in the operation and design of reservoirs. The model is based upon the representation of the flood series as a Poisson counting...
Analysis of Onsite Measurements of Scour at Piers
Existing onsite measurements of local scour at bridge piers were assembled and analyzed to obtain an equation that predicts the expected maximum depth of local scour at a bridge pier....
Spline Interpolations for Water Hammer Analysis
The method of characteristics (MOC) with spline polynomials for interpolations was investigated for numerical water hammer analysis. The overall accuracy is significantly improved compared...
Time Averaged Estuarine Mass Transport Equations
A methodology for deriving time averaged mass transport equations for estuaries having weakly nonlinear long wave dynamics is presented. A 2D in-plane advection-dispersion equation for...
Lagrangian Modeling of a Suspended-Sediment Pulse
The one-dimensional Lagrangian Transport Model (LTM) has been applied in a quasi two-dimensional manner to simulate the transport of a slug injection of microbeads in steady experimental...
Dormant Season Evapotranspiration in Alfalfa
Weekly values of maximum temperature, minimum temperature, and solar radiation were examined for their effect upon weekly dormant season evapotranspiration (ETdorm) in perennial alfalfa....
The Relationship of Benefits to System Size for Irrigation Projects
This paper presents a generalized linear programming (LP) and farm budget model for optimization of on-farm irrigation benefits resulting from variations in irrigation project size. The...
Meixner Functions Model Crop Yield vs. Applied Water
Most crop production functions are reported as linear functions even though everyone knows they are not. The few examples of non linear crop production functions that exist in the literature...
An Analytically Derived Distribution Function for Flood Volume
A general stochastic model is proposed to determine analytically the distribution function for flood volume. A flood event in this study is defined as an unbroken sequence of consecutive...
Applications of an Integrated Traffic Analysis Package
This paper presents an integrated traffic analysis package called AAP (the Arterial Analysis Package). AAP, which was developed by the Federal Highway Administration (FHWA), contains three...
Finite Element Idealization for Linear Elastic, Static, and Dynamic Analysis of Structures in Engineering Practice
This report by the Finite Element Idealization Task Committee is a comprehensive aid for modeling structures for finite element analysis. The first part covers static analysis. Aspects...
Interactive Computer Graphic Seismic Design of Frames
An interactive computer graphics approach for earthquake resistant design of two and three-dimensional steel frames is presented. Analysis and design are possible from code-related equivalent...
Finite Element Analysis of Punching Shear Strength of Reinforced Concrete Structures
The analysis of reinforced concrete structures using up-to-date computer graphic capabilities is presented. A wide range of linear and nonlinear problems are the subject of this investigation....
Optimal Collection of Data for Parameter Identification
In this paper, the author attempts to study the optimal spacing of measurements for a structural system modelled by a single-degree-of-freedom oscillator so that the variance of one or...
Green's Function Implementation for Pile Analysis
This paper describes the implementation of a new Green's function based on a layer stiffness approach in a boundary element analysis of harmonically loaded pile groups embedded...
Nonlinear Response Combination in Seismic Analysis
Simple, approximate methods are developed to evaluate the maxima of response measures which are nonlinear functions of modal responses to seismic input. Examples for such response quantities...
Random Vibration of Mass-Loaded Rectangular Plates
The classical method of separation of variables in conjunction with the Green's function of the vibrating plate is used to obtain the solution of the free vibration problem...
