Particle Sizes in Flocculation and Sedimentation: Models and Experiments
D. F. Lawler et al. developed a model for flocculation, sedimentation, and filtration and predicted the effects of particle size distribution and concentration of the influent in water...
Unique Ash Disposal Facility Protects Water Quality
Flowable Fly Ash: A New Cement Stabilized Backfill
Cement stabilized fly ash placed at a plastic fluid consistency is a new structural backfill material that flows into place, either above or below water, without using sophisticated construction...
Conserve On-Farm Irrigation Water with Soil-Cement
Water Quality Management Techniques for Reservoirs
The curtailment of nutrient, organic matter, and sediment loads to reservoirs is a direct means for improving water quality. However, the recycling of nutrients and/or the failure to sufficiently...
Dredging in a Stratified Estuary
Grays Harbor is a moderately stratified estuary on the Washington coast. During the summer of 1983, while hopper dredges worked the upper reaches of the estuary, extensive water quality...

Activities are centered in the W. M. Keck Laboratory of Hydraulics and Water Resources. Research projects active at the Laboratory reflect a continuing commitment to traditional areas...
Fluorescent Tracer Mixing Experiments in Glenmore Reservoir, Calgary
Mixing studies using salt and dye as tracers were conducted in Glenmore Reservoir which is the major water supply for the City of Calgary, Alberta. The purpose of the studies was to find...
Upgrading Water Filtration Plants
Adding or improving mixing, flocculation, and sedimentation devices, and changing filter media can significantly increase water filtration plant capacity. Water quality can often be improved...
