Convergence and Divergence Between Regulated Riparian and Prior Appropriation Provisions in the ASCE Model State Water Rights Code
Although there are two major American water rights systems-- riparian and prior appropriation--there are mixed systems and variations within each major type. The ASCE Model State Water...

Willingness-to-Pay for Alternative Shortage Probability Distributions
Mathematical programming is used to derive estimates of the willingness-to-pay of water service customers for improvements in water supply reliability. Reliability is represented as a...

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...

Summer Engineering Outreach Program for Native Americans
Minorities are significantly underrepresented in engineering, science and math fields in the United States. To attract and retain capable minority students will require the development...

Startplan: Producing Schedule Templates Using IRMA
The Information Reference Model for AEC (IRMA) is a generic information modeling standard to support computer-integrated construction (CIC). Although IRMA is still in a conceptual stage,...

The Context–Oriented Model: An improved Modeling Approach for Representing and Processing Design Standards
Current electronic design evaluators employ one of three primary computational models to represent a design standard: the Condition/Consequent, Object-Oriented and hybrid models. The problems...

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...

Multi-Objective Optimization of Construction Schedules
This paper focuses on the multi-objective deterministic and stochastic modelling and optimization of construction tasks scheduling. Of particular importance is a frequency need to satisfy...

Modeling to Generate Alternatives in Discrete Structural Optimization
Structural design, like other complex decision problems, involves many trade-offs among competing criteria. While mathematical programming models are increasingly realistic, there are...

Probabilistic Modeling of Scheduling Uncertainty: Methods and Tools
This paper provides an overview of probabilistic project scheduling methodologies and tools. It emphasizes the practical application of Monte Carlo simulation in modeling activity durations....

Metamodeling Approach for Approximating the Operating Characteristics of Series of G/G/1 Queues on Congested Waterways
A simulation model representing waterway networks with queues at locks has been developed and validated. Functions developed from queueing theory were formulated to describe the operating...

Formal Specification of AEC Product Models
This paper illustrates the use of equational specifications in developing product data models. This approach enables a precise and abstract description of products, where both syntactic...
