Effect of Nonstandard Rainfall Distributions on Stormwater Management Detention Basins
A rural watershed is modeled to determine the effect of varying rainfall patterns on stormwater management detention basins designed for center peaking events. A hydrologic model of the...
Missouri River Least Tern and Piping Plover Model Development
As part of the update of the Missouri River Master Water Control Manual, the U.S. Army Corps of Engineers is evaluating the effects of numerous water management alternatives on endangered...
Low-Flow Frequency Analysis with Censored Data
Log-linear regression models are often fit to low-flow quantile estimates from gauged sites to obtain a relationship for estimating low-flow quantiles at ungauged sites. In some regions...
Homogeneity Tests Based Upon Gumbel Distribution
This paper analyzes the performance of three homogeneity tests for Gumbel distributed flood flows. The classic Dalrymple test, a method-of-moment Cv test, and a normalized-quantile test...
A Regional Model of Daily Streamflow for the Northeast United States
A regional flow duration curve (FDC) model is under development which relates daily streamflow at 166 unregulated basins in the northeastern U.S. to watershed and climatic characteristics....
Analysis of Missouri River System Operations Alternatives
The Corps of Engineers is conducting a study of alternative water control plans for the exiting Missouri River Mainstem System. Data on the effects of the alternatives on the various project...
Evaluating the Steady State Stochastic Dynamic Programming Model for the High Aswan Dam
The paper describes the results of a study to critically evaluate and test the Steady State Stochastic Dynamic Programming model (SSDP). Whenever a reservoir computer model is developed,...
A Salmon Population Model for Evaluating Alternative Flow Regimes
Salmon populations in many Pacific coast rivers are in decline and in danger of becoming threatened or endangered. A fish population model that tracks chinook salmon from eggs to the immature...
Improved Computer Simulation of 3D Wind Flow Around a Building
A two-layer method combining the k-? model with the one-equation model near the wall has been tested in computing the wind conditions around a cubic building. In contrast with the simple...
Concurrent E-I Algorithm in Structural Dynamics
A concurrent explicit-implicit algorithm for time integration of the differential equations arising from a finite element discretization is described. The first step of the method consists...
Computer Applications in Structural Analysis and Design
The computer programs have been increasingly used in structural analysis and design to improve productivity. The computer applications in areas of automatic member and foundation design...
Strategic Ship Routing Impacts of Temporal Coverage with Real-time Satellite Altimeter-Based Current Information
We investigate strategic ship routing impacts of temporal coverage with real-time satellite altimeter-based current information. We sample underlying daily `true' current patterns along...
Impulse Effect on Redundancy of a Tied-Arch Bridge
This paper studies the redundancy of a tied-arch bridge using a 3-dimensional finite element computer model. By using static incremental loading simulation, a tied-arch bridge designed...
Discrete Modeling of Soil-Structure Interaction Under Dynamic Loading
A proposal of discrete modeling useful to describe behavior of structures burried in the ground under air explosion is presented. In the modeling emphasis is laid on determining the space...
An Object-Oriented Approach to PC Finite-Element Solutions
A methodology for developing a finite-element program with a variety of applications within civil engineering is presented. Application include simple structural analysis, groundwater...
Developing an Object Based Planning System for Precast Concrete Building Structures
This paper presents the organization of an object based planning system for determining the preliminary costs, schedules and resources for precast concrete building structures. First,...
Computer-Assisted Instruction in Civil Engineering
Computer-assisted instruction (CAI) software offers several advantages over traditional classroom instruction which makes it a useful addition to any curriculum, and the area is rapidly...
A Real-Time Graphical Interface to a Two-Dimensional Groundwater Flow and Mass Transport Model
This paper describes the implementation of a graphical interface to the U.S. Geological Survey's Method of Characteristics (MOC) groundwater flow and mass transport model....
Mat Foundation Design: An Historical Perspective
Nearly a half century ago, Karl Terzaghi rationalized the analysis and design of mat foundations with the conclusion that subgrade reaction was the most important variable. Soon after...
Displacement of Landmark Building Resulting from Adjacent Construction Activities
This paper describes the observations and presents comments related to the measurement of settlement and the avoidance of damage to a historic structure in the City of New York from adjacent...
