Instream Flow Strategies for Operation of the Federal Central Valley Project
Federal Central Valley Project (CVP) operations and policies of reservoir storage and river releases for fish and wildlife protection and restoration are discussed. Prescribed strategies...
Changes of Water Rights - The Colorado Experience
This paper describes engineering efforts which are involved with the judicial changes of water rights in the State of Colorado....
Object-oriented Model of Colorado River Salinity
A salt balance is incorporated into an object-oriented river-basin model and applied to the Colorado River. The model simulates seasonal variations in the basin's water balance and employs...
Prediction of Gravel Bedload with SAM
Bedload measurements for Little Beaver Creek in Colorado were used to test the sediment transport functions included in SAM. The test results showed that Toffaleti predicts total bedload...
Modeling Flow in Variably-Saturated Porous Media
An expression for effective hydraulic conductivity to solve groundwater flow problems is developed. Also, a refined Monte Carlo (MC) simulation procedure is proposed. The developed methodologies...
Recent Advances In Well Hydraulics
Most books and papers on well hydraulics are mostly or entirely aquifer hydraulics. The phrase, 'well hydraulics,' implies a study of the flow into and within a well proper. There has...
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...
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...
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...
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...
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....
Blast Densification of a Thick, Loose Debris Flow at Mt. St. Helen's., Washington
Numerous debris flows occurred during the 1980 eruption of Mt. St. Helen's in Washington State. The proposed location of Bridge 12 over Coldwater Creek along State Route 504 is underlain...
Waste Minimization and Recycling by Microfiltration during Nitrocellulose Manufacturing
A plant survey was conducted to determine the amount of nitrocellulose (NC) discharged with process water from each of five sequential NC purification processes. Wastewater samples were...
