Artificial Recharge in Finland
There are four reasons for artificial recharge of ground water in Finland: 1. The replenishment of aquifers by lake water. 2. To use aquifers as part of surface water treatment process....
Damage Assessment and Seismic Behaviour of Steel Buildings in Mexico City
Preliminary reports on the September 1985 earthquakes indicated 10 steel buildings collapsed and 2 more severely damaged. The total number of buildings found either collapsed or severely...
Crossing A Freeway
The Washington State Convention and Trade Center in Seattle is being constructed on air rights spanning Interstate-5, adjacent to the seven acre Freeway Park that also spans the highway....
Natural Stabilization of an Eroded Permafrost Site
The paper referred to in this abstract discusses the erosional processes during and after the initial failure, proposed solutions to repair and stabilize the site, and details of the performance...
OTEC: At the Brink of Commercial Reality?
The development of ocean thermal energy conversion (OTEC) has traditionally been a question of technological feasibility and economics. Recent research and design developments, however,...
Forecasting Currents in Coastal Waters
A service for current and temperature forecasts has been developed for the coastal waters along the west coast casts has led to several improvements. Future modeling efforts are expected...
Geomorphology, Convergent Margins and Earthquakes
Underthrusting along convergent plate margins, is commonly accompanied by the occurrence of shallow focus, large magnitude thrust earthquakes ( greater than magnitude 7. 5). In the subduction...
A Safer Earthquake Design Approach
The Uniform Building Code earthquake code permits taking advantage of a frame's capacity to absorb energy at stresses beyond yield. Dropping that provision would save lives....
Density Currents in Clarifiers
This paper discusses internal flow regimes associated with the density currents due to diurnal heat loading. The reported studies were carried out with the aid of physical models....
Plume Underflow Interaction in Natural Enclosures
A preliminary investigation into the feasibility of using a hot-water plume to intercept and entrain a cold underflow is presented. The investigation involved an adaptation of existing...
A Stratified Mixing Channel: Theory and Experiment
The performance of a deep and stratified mixing channel is assessed theoretically and experimentally. The channel has a rectangular cross-section, a negligible longitudinal slope and is...
Consolidation of Slurried Soils
This paper describes the use of large strain consolidation theory and centrifugal modelling to study the consolidation behavior of slurries. Laboratory testing of the slurry is needed...
Dispersal of Dredged Material Disposal Plumes
An empirical model describes dispersal of dredged material disposal plumes in an urban estuary, Central Long Island Sound, during spring of 1983. The model uses in situ current meter data...
Dormant Season Evapotranspiration in Alfalfa
Weekly values of maximum temperature, minimum temperature, and solar radiation were examined for their effect upon weekly dormant season evapotranspiration (ETdorm) in perennial alfalfa....
Adding a Climatic Interface to Electronic Irrigation Controllers
Automated irrigation systems have traditionally relied on a time based controller set to operate the irrigation system for a specific duration and frequency. To determine the duration...
Physical Model Verification of a Coastal Discharge
A 1:75 scale physical model of a thermal discharge into a rocky, semi-enclosed bay was verified against extensive field data. The model accurately reproduced the prototype temperature...
Prediction of Deformations Due to Heat Curving
This paper summarizes the state of the art in the thermal deformation techniques. Alternate analytical methods are described. The limitations and accuracy of these models are noted, and...
Geologic Assessment of Seismotectonic Hazards
Design and modification of dams require evaluation of potential seismotectonic hazards based on consideration of the historic earthquake record and deterministic evaluation of geologic...
Seismic Decision Analysis for Jackson Lake Dam
This paper presents a framework for decision analysis that can be applied to seismic dam safety problems. The framework provides a means for displaying uncertainties in a manner that allows...
Maximum Response of Buildings to Multi-Seismic Input
The paper presents a technique of determining the maximum response of a torsionally-translationally coupling structure subjected to three ground translational components. It was found...
