Predicting Hydrologic Impacts of a Severe and Sustained Drought on the Colorado River Basin
We investigated the impacts of a severe and sustained drought (SSD) on the hydrology of the Colorado River Basin. The simulation was carried out using the Colorado River Network (CORN)...
Development and Application of Long Range Study (LRS) Model for Missouri River System
The Long Range Study (LRS) Model is a simulation model developed in the 1960's develop and test criteria for operation of the Missouri River mainstem reservoirs through an extended period...
Computer Simulation Model of the Integrated Local Water Supply Plan for the City of Wichita, Kansas
The City of Wichita, Kansas will require additional water supply sources to meet projected future water demands. A study of options identified a supply plan with integrated use of local...
Development of a Wetland/Riparian Resource Model for the Missouri River System
Wetlands and riparian areas are significant resources along the Missouri River, providing important fish and wildlife habitat. These resources required evaluation as part of the review...
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...
Development of Environmental Impacts Model for Missouri River System
The Corp of Engineers is reviewing the Missouri River Master Water Control Manual with the goal of determining the best plan for the Missouri River Basin. The Environmental Impacts Model...
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....
WATSUP: A Simulation Model for Water Supply Cost and Reliability
WATSUP (Water Supply) is a computer model developed to provide a prototype modeling tool for planners to estimate the costs and reliability of urban water supply systems on a regional...
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,...
Wet Detention Facility Pollutant Removal Modeling
This paper documents development of the WETPOND model, which simulates long-term pollutant removal by a wet detention facility. Pollutant removal is determined with an EPA procedure that...
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...
Graphical-Based Productivity Transient Investigation Using DISCO
Construction operations involve complex resource interactions and are typically performed in the field with exogenous factors such as inclement weather conditions and equipment breakdowns....
An Integrated Approach To Repetitive Construction Planning
Repetitive construction projects are unsuited for the use of the Critical Path Method (CPM) for their scheduling. Statistical simulation techniques offer a scheduling alternative, but...
Interpretive and Modelling Problems of Risk and Uncertainty in Bidding Techniques
This paper considers the implementation of policy, strategic and tactical bidding and the processes of devolution of the risk and uncertainty in a corporate management context....
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...
Random Vortex Models in Wind Engineering
Random vortex methods are Lagrangian particle-based numerical simulation schemes especially appropriate for Wind Engineering simulations. Vortex methods do not suffer from numerical diffusion...
State and Resource Based Construction Process Simulation
Stroboscope is a programming language for construction process simulation. The programming language provides access to the state of the simulation and to the properties of resources. It...
