3-Dimensional Groundwater Modeling of the West Coast Basin Barrier
This paper describes a practical application of groundwater modeling of seawater intrusion in southern California. The West Coast Basin is one of the major groundwater reservoirs underlying...
Hydrodynamic Dispersion: Estimation and Prediction
The dispersion of dissolved, nonreactive tracers in groundwater is governed by diffusion and advection. A.E. Scheidegger introduced the term dispersivity to describe the effect that a...
A Numerical Solution Technique for Incompressible Flow
Presented is a numerical solution technique which employs the explicit predictor-corrector scheme of R.W. MacCormack in solving the governing two-dimensional equations of motion on a staggered...
An Error Analysis of the Dynamic Wave Model
The Dynamic Wave Operational Model (DWOPER) is used to forecast river stages on the Lower Columbia River. DWOPER was developed by the National Weather Service's Hydrologic...
Computer Aided Hydraulic Design of Open Channels
The results of tests by the U.S. Army Corps of Engineers District, Los Angeles (LAD), became a major part of the Corps' EM 1110-2-1601, Hydraulic Design of Flood Control Channels....
Debris-Flow Research and Engineering Practice
For debris-flow analysis to enter standard engineering practice, future research must extend existing models to deal with major complications that arise in field practice. This paper reviews...
Two-Dimensional River Modeling of Buckhorn Creek
A two-dimensional Finite Element Surface Water Modeling System (FESWMS-2DH) was used to simulate flow at a bridge crossing of a heavily vegetated flood plain where State Highway 130 crosses...
Candor Chasma Camp
This paper proposes a camp at Mars, in the Coprates region of the Valles Marineris rift, just below the equator on Candor Mensa 6�-12'S, 73�-30'W. Beginning at...
Dynamic Analysis of the Joint Dominated Beam
A method is presented herein to determine the vibration modes of the Joint Dominated Beam. An example of a cantilever beam is selected for this purpose. The truss type beam is analysed...
Differential Gravitional Forces on Large Space Structures
Effects of the differential gravitational forces have been investigated simultaneously on the orbital motion, attitude motion, and axial deformation of a very large axially flexible space...
The Planar Truss - An Active Control Test Bed
The authors have developed a laboratory planar truss and structural dynamic models which correlate well. The inherent fraction critical damping (? = .004 for the first mode) is very low...
The Liquid Droplet Radiator in Space: A Parametric Approach
This study is a parametric investigation of the performance and operating characteristics of a cylindrical Liquid Droplet Radiator (LDR) for use in space. The LDR system mass per heat...
Surgery in the Microgravity Environment
As man becomes more active in space, the possibility of major medical emergencies requiring surgical procedures will increase. Surgery in the microgravity environment involves many challenges...
Earthquake Engineering and Soil Dynamics II?Recent Advances in Ground-Motion Evaluation
Ground-motion determination for analysis and design of engineering structures is a shared, interdisciplinary task involving geologists, seismologists, geophysicists, geotechnical engineers,...
Simulated Water-Quality Changes in Detention Basins
A study has begun to simulate movement of stormflow through detention basins at four locations in the Irondequoit Creek watershed and determine the effect on peak flow and water quality....
Preparations for the Future?The European Highway Community
The need for infrastructural capacity in the future in Europe has been investigated by the European Conference of Ministers of Transport - ECMT. The principal traffic considered was international...
Natural Vibrations of Cables in a Flowing Fluid
Cable segments are important components in a wide variety of marine operations. Their nonlinearities are primarily geometric as characterized by large displacements and load-dependent...
Analysis of Hydraulic Impacts at the Tucson Reclaimed Water Recharge Project
The Tucson Reclaimed Water Recharge site has been implemented with increasingly sophisticated calculation methods as data collection efforts advanced. Initial project scoping utilized...
Infiltration Wells in the Lakes Around the Future Markerwaard Polder
Drainage and reclamation of the Markerwaard polder in the Netherlands may cause damage to buildings and infrastructure in the eastern part of North-Holland because of subsidence. Drawdown...
