Peat Filtration for Oil Removal
An investigation was carried out to assess the potential of horticultural peat produced in Saskatchewan as a filter medium in treating five oil-in-water emulsions (standard mineral oil,...
Kalman Filter in Real-Time Hydrologic Forecasting: A Tutorial
The Kalman filter provides an algorithm by which measured streamflow can be used to update the estimated hydrologic state of the watershed as determined from the application of a hydrologic...
Using Sediment-Threshold Theories in Waves and Currents
Fundamentally different threshold-of-motion theories were applied to sand transport in two different coastal environments. Several recommendations for threshold application were reached....
Instability of Bed-Surface Composition Due to Sorting Process in a Stream Composed of Sand and Gravel
Wavy patterns of sorting are often observed in a stream composed of sand and gravel, and they are regarded as instability of bed-surface composition due to selective bed-load transport...
A Finite Element Application of Sand Terrace Formation Process
In this paper, the formation process of a sand terrace in front of river mouth is simulated numerically by means of the finite element method. The two-step explicit scheme is applied as...
Sediment Transport Modelling from Grain Size Data
Grain-size analysis can be useful in determining some of the hydrodynamic aspects of the evolution of a natural sand body. The suite statistics approach minimizes single-sample anomalies...
The Structure of Intermittent Sand Suspension Events Under Mild Wave Conditions
Nearshore sedimentation processes are being actively investigated through a series of research projects at the University of Miami. Quantitative measurements of waves, currents, and suspended...
Sediment Transport Rate for Non-uniform Sand
Based on the equations of bedload transport by authors, the functional relation of total sediment transport capacity of flow has been found. The modifying coefficient due to non-uniformity...
Sediment Transport Due to Channel Flushing
Blocking of rivers and canals by sediment due to landslides or dumping of waste create problems of upstream flooding and drainage. Experiments are carried out in the present study on flushing...
Sorting of Mixed Sand on a Two-Dimensional Beach
A numerical method is developed to predict temporal variations of the sea bed topography and the bed-material composition. The predicted results are compared with the measurements in a...
Stochastic Modeling of Groundwater Contamination?A Distributed Parameter Kalman Filtering Approach
Stochastic methods are applied to the analysis and prediction of large scale solute transport in saturated heterogeneous porous media. An extended distributed parameter Kalman Filter which...
The Physics of Sediment Transport by Wind and Water
Sponsored by a special projects committee under the guidance of the Sedimentation Technical Committee of ASCE. This collection contains noteworthy,...
New Found Youth for an Old Foundry
The Grey Iron plant, central foundry division of General Motors Corp., in Saginaw, Mich. conducted a study to evaluate the capacity and tooling of future casting operations of the more...
Ground Water Recharge Through Excavated Basins
Excavated basins were used to bypass slowly permeable soils in the Southern High Plains and artificially recharge the Ogallala aquifer. Recharge rates with turbid playa water were as rapid...
Ogallala Recharge with Stormwater Collected in Playa Lakes
Runoff occurring from this precipitation collects in playa lakes. The bottoms of these lakes are comprised of clays and silts which prevent or retard infiltration in subsequent recharge....
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...
Beach Nourishment at Myrtle Beach, South Carolina: An Overview
The purpose of this paper is to summarize the Myrtle Beach nourishment project as it proceeded from the geotechnical evaluation of potential borrow sands, to permitting and design, and...
Artificial Beach Design, Lake Forest, Illinois
A system of beaches and offshore breakwaters was designed to protect eroding bluffs along the shoreline of the City of Lake Forest. The beach system consists of sand fill contained by...
Sand Bypass System at Oceanside, California
This paper describes the design and development of an experimental sand bypassing and channel maintenance system using jet pumps and fluidizers. The system was developed as a possible...
Coastal Dunes for Protection and Sand Resources
Massive mining of dune sand on the north coast of Puerto Rico has impaired the natural ability of the dunes to protect the coast from high waves and long-term erosion. This paper presents...
