Stochastic Conditional Simulation of Berea Sandstone Geophysical Properties with a Counterpropagation Neural Network
The ability of a counterpropagation neural network to produce stochastic conditional simulations is applied and evaluated on a real dataset. This network functions as a nonparametric clustering...
Non-Destructive Strength Evaluation of a Continuous, Reinforced Concrete Slab Bridge
In the state of New Mexico, a significant number of reinforced concrete slab (RCS) bridges provide service on interstate highways I-10, I-25, and I-40 that are subjected to large amounts...
Application of TOPNET in the Distributed Model Intercomparison Project (DMIP)
This paper describes the application of a networked version of TOPMODEL, TOPNET, as part of the Distributed Model Intercomparison Project, DMIP. The model implementation is based on a...
Mathematical Modeling of Watershed Hydrology
Mathematical modeling of watershed hydrology is employed to address a wide spectrum of environmental and water resources problems. A historical perspective of hydrologic modeling is provided,...
Impact of Chemically-Induced Clay Transport and Deposition on the Hydraulic Conductivity of a Natural Sand
The purpose of this paper is to understand in part the dynamic impact of surfactants on hydraulic conductivity for designing enhanced pump and treat operations. This paper has two aims:...
Bayesian Approach to Support Design of a Groundwater Long Term Monitoring Plan
This paper discusses a retrospective data assimilation approach that allows one to examine the spatial and temporal differences between forecast and observed states. Their stability, or...
Spatial Decision Support System for River Basin Management
MODSIM is a generalized river basin network flow model designed to simultaneously assure that water resources are allocated according to physical, hydrogeological, and institutional/administrative...
Preliminary Assessment of Bacteria Abundance in Rivers of the Pantanal Wetlands -- Brazil
Heterothrophic bacteria play an important role in the carbon flux of aquatic environments, specially in flooded areas, where they are considered to be a source of organic matter. They...
Design Live Loads for Parking Garages
The objective of this research project is to obtain a better understanding of parking garage live loads and to recommend an appropriate value for design. A load survey was conducted in...
Order Amid Uncertainty (Available in Geoenvironmental special issue only)
Bayesian statistical methods allow engineers to deduce probabilities from incomplete information. If there is a theoretical or empirical reason why a particular probability distribution...
Basin Response Time: Potential Hydrologic Basin Handprint
Hydrologic lead time is an important factor in many water resources engineering applications. The determination of the response time of a watershed to runoff-producing rainfall is the...
Comparison of Complete Modeling/Simplified Modeling of Zaragoza City Water Supply Network
(No paper) Zaragoza is a Spanish city with 600.000 inhabitants and a water supply network of 900km long. The Council technical services uses a Microstation based GIS, GRED, for network...
Securing the Stone
To prevent spalling at edges on thin stone veneer, engineers who design stone cladding pay special attention to the connection details. Kerf clips, 100-150 mm long, that distribute load...
Spatial Analysis in Soil Dynamics and Earthquake Engineering
This Geotechincal Special Publication contains the papers presented by the invited speakers in the sessions on Spatial Analysis in Soil Dynamics and Earthquake Engineering held during...
Photogrammetric Mapping
Technical Engineering and Design Guides, as adapted from the U.S. Army Corps of Engineers, No. 14. This manual provides procedures, minimum accuracy...
Evaluation of Sampling Properties of General Extreme Value (GEV) Distribution-L-Moments Vs Conventional Moments
The sample estimates of conventional moments are shown to be biased and this bias increases for small samples, and especially so when the skewness is high (Wallis et al., 1974). The recently...
FLODRO 2.0: A User Friendly Personal Computer Package for Flood and Drought Frequency Analyses
The use of personal computers have changed dramatically the way to perform several studies related with hydrological problems. The increased capabilities of the current generation of personal...
Dam Foundation Erosion Study: The Design of a Sidewall Orifice for Simulation of a Free Trajectory Overtopping Jet
This paper describes the design of a sidewall discharging orifice for simulation of a free trajectory overtopping jet. A sidewall orifice discharges through the sidewall of a pipe. The...
Automatic Control of Flocculation Processes
A control system for flocculation, used in water and wastewater treatment operations is being developed. The approach is based on detailed particle size distribution measurements of influent...
Flow through Vertical Barrier Screens?Numerical Model
