DISCUSSION. EXPERIMENTS WITH HYDRAULIC MODELS OF PORT LYTTELTON.

Calibration of Hydraulic Network Models

Computer models for analyzing and designing water distribution systems have been available since the mid 1960's. Since then, however, many advances have been made with regard to the sophistication and application of this technology. A primary reason for the growth and use of computer models has been the availability and widespread use of the microcomputer. With the advent of this technology it ...

Discussion of Reports on Cloud Seeding Experiments

The work on cloud seeding which has been described in this Symposium is new to me. I find it extremely gratifying to encounter such well designed and carefully conducted experiments in which the principles of randomization have been scrupulously adhered to. A few of the speakers appear to think that there is some conflict between a "statistical" experiment, fulfilling the requirements of experi...

Hydraulic Experiments for Determination of In-situ Hydraulic Conductivity of Submerged Sediments

A new type of in-situ hydraulic permeameter was developed to determine vertical hydraulic conductivity (VHC) of saturated sediments from hydraulic experiments using Darcy's law. The system allows water to move upward through the porous media filled in the permeameter chamber driven into sediments at water-sediment interface. Darcy flux and hydraulic gradient can be measured using the system, an...

Experiments with Dynamic Topic Models

General summary of news content is a task under the general heading of“information summarisation,” and it is recognised as a way of overcoming information overload. How does one summarise a large number of articles with their time as well as topical content? Here we introduce one technique, dynamic topic models, built using discrete non-parametric techniques, and demonstrate our software that c...
