Kaplan Blade Angle Controller
This paper describes a recently developed computerized Kaplan blade angle controller that is capable of improving turbine performance. Model Tests or Index Tests produce the Three-D-Cam...

Characteristics of Nonstationary Response of Linear Systems
A new formulation for the statistics of the response of linear systems to nonstationary excitation is developed. Both the process and its envelope are examined and exact statistics are...

Maximum Value Statistics for Transient Response of Linear Structures
The mean and the variance are investigated for the maximum absolute value of a nonstationary process which represents the response buildup of a linear oscillator. The mean and variance...

One Solution for Different Stochastic Systems
It is shown that different dynamic systems under different sets of random excitations can share an identical probabilistic solution. Such systems are said to be stochastically equivalent,...

Efficient Probabilistic Structural Analysis Using an Advanced Mean Value Method
An advanced mean-value (AMV) method for probabilistic structural analysis is presented. This method blends the conventional mean value method with the advanced structural reliability analysis...

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...

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....

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...

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...

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...

Bounded State Control of Structures with Uncertain Parameters
The control of linear systems in the presence of set constrained external disturbances has been investigated maintaining the states in a prespecified region by estimating the maximum reachable...

Intelligent Central Database System for Synchronized Distributed Processing of Large Hydrologic Packages in Local Area Networks
The nodes of a local area network can be dedicated to the independent routines of a large hydrologic/hydraulic package. The server of the network can be dedicated to the control of the...

Lagrangian-Eulerian Approach to Modeling Contaminants
A Lagrangian-Eulerian modeling approach predicts potential contaminant distributions resulting from the disposal of sewage sludge at the Deepwater Municipal Disposal Site off the northeast...
