Sedimentation of Waste Particles in Coastal Waters
Environmental effects associated with various ocean disposal practices are determined to a large extent by the fate of waste particles. The importance of coagulation on particle deposition...

Brownian Coagulation in the Initial Mixing Region of a Buoyant Plume
The paper discusses reactive systems that share the following common phenomenon: their reaction is either controlled by both kinetics and diffusion, or fully by diffusion. It reports on...

Streamflow Monitoring with Ultrasonic Recorders
In September 1983, four new streamflow monitoring sites were established in a west Chestnut Ridge catchment at the Oak Ridge National Laboratory. Ultrasonic level/flow recorders were used...

Computer-Assisted Problem Solving in Hydraulic Engineering
A number of practical hydraulic problems may be solved using software that allows interaction at the equation level rather than through higher level languages. This paper presents examples....
