This paper presents a novel method for distributing the heat generated by waste containers emplaced in the proposed high-level nuclear waste site at Yucca Mountain, Nevada. The method...
Wave Propagation in Hyper-Structures
The concept of hyperelement was introduced by E. Kausel and J.M. Roesset, 1977 in connection with the derivation of the dynamic stiffness matrix for layered continuum problems involving...
Modeling Volatile Organic Transport with Vapor Sorption
A flexible finite element simulation model is developed to predict the movement of volatile organic compounds in variably saturated subsurface regions. The model incorporates both the...
An Eulerian-Lagrangian Model for Sediment Transport in Estuaries
We describe a new depth-averaged numerical model for the simulation of the fate of sediments in estuaries. The model, denoted ELAsed, includes the following distinctive characteristics:...
Hydrodynamic Modeling on Vertically Mixed Bays
Extensive model-data comparisons of sea surface elevations and vertically-averaged velocities are performed on the Peconic Bays Estuary, New York, a system of interconnected bays where...
Multi-Dimensional Modeling of Hydrodynamics and Salinity in San Francisco Bay
This paper presents a modeling study of salt intrusion into San Francisco Bay that used a three dimensional finite element model capable of different approximation levels in different...
Technical Work on Flexible Pipe/Soil Interaction Overview?1990
Research in the laboratory and field have been ongoing for the past seventy years on flexible pipe/soil interaction. Virtually all of the early work was done on steel pipe. During the...
Numerical Analysis of Flexible Culverts in Layered Soils
The deformation of flexible culverts is analysed using the finite element method as tool. Results of calculations for installation, traffic and time dependent loads are presented for culverts...
Behavior and Design of Gravity Earth Retaining Structures
This paper summarizes recent research on the soil-structure interaction of gravity earth retaining structures and provides new design procedures for these structures. The procedures currently...
Finite Element Analysis of Hillslope Variations in Surface Runoff
Watershed management decisions are aided through an accurate understanding of hydrologic processes. The finite element method applied to surface runoff with spatially variable hydraulic...
Strategies to Reduce Salt Load in Drainage Water
A study of irrigation efficiency, drainage flow and trace element loading in the drainage water from a 14000 ha irrigation district on the west side of the San Joaquin Valley of California...
Reduction of Deep Percolation and Drain Water
Management of irrigated agriculture for control of toxic trace elements in agricultural drainage waters must include consideration of a variety of factors and their interactions with one...
Geochemical Factors Affecting Trace Element Mobility
Selected geochemical processes to be considered when modeling the movement of trace elements in soils are presented. The topics covered include: solid phase-solubility equilibria, ion...
Hydrogeologic Factors Affecting Trace Element Mobility
Alluvial deposits often comprise the aquifer beneath irrigated lands in the southwestern U.S. The presence of buried stream channels in, and layering of, shallow alluvial deposits are...
Prognosis on Managing Trace Elements
Management options assessed for trace elements discharged from irrigated lands include source control, drainwater reuse, drainwater treatment and removal of contaminants, disposal, and...
San Miguel Water Supply Study: A Case Study in Non-Structural Alternatives for Improved Irrigation Water Supplies
The San Miguel study area is located in southwestern Colorado sixty miles south of Grand Junction. Investigations of alternatives for developing additional water supplies involved mainstem...
Water Quality of Jubba River in Somalia
