REPORT OF THE STREAM-FLOW PREDICTION SUBCOMMITTEE

the effects of changing roughness on the flow structure in the bends

flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...

Stream Flow Prediction in Flood Plain by Using Artificial Neural Network (Case Study: Sepidroud Watershed)

In order to determine hydrological behavior and water management of Sepidroud River (North of Iran-Guilan) the present study has focused on stream flow prediction by using artificial neural network. Ten years observed inflow data (2000-2009) of Sepidroud River were selected; then these data have been forecasted by using neural network. Finally, predicted results are compared to the observed dat...

Report of the Subcommittee on Astronomy.

You may recall the ancient days of Rome when the people annually gathered to pay an offering of oil and wine, of milk and violets to the spirits of, their ancestors, from the study of whose examples they gained for themselves and inculcated in others a respect for the virtuous past. So we say our aves to the great past out of which we anid all our guiding principles in individual life, in the c...

Report of the Subcommittee on Pathology.

THE Committee on Research in Pathology recommends: 1. Nature of Work to Be Aided.-In the awarding of grants that preference be given to problems of etiology, immunity, functional pathology and chemical pathology, as representing the most profitable lines of investigation at present. 2. Laboratories or Individuals to Be Aided. -It is believed advisable to give grants preferably to laboratories p...
