SPRING ICE PROCESSES AT THE ZHAYIK RIVER (URAL)

Forecasting Ice-Affected Rivers at the Northeast River Forecast Center

Each winter and early spring, the Northeast River Forecast Center (NERFC) faces the challenge of forecasting river stage and flow for ice affected rivers. “Stage versus flow” relationships tend to be in error and there is a lack of real-time information about the nature of the ice cover. The NERFC is investigating methods to forecast river stage and flow for ice-affected rivers because in times...

The Hydraulics of River Ice

Henry S. Santeford;"~ln'd GeorgeR . Alger Department of Civil Engineering, Michigan Technological University Houghton, MI 49931 U.S.A. INTRODUCTION The formation and occurrence of an ice cover on an open channel may cause a very dynamic alteration in the flow characteristics. At times, the alterations will represent some of the largest natural changes that will occur on a giVen stream. Yet, Dn ...

The impact of spring floods on macroinvertebrates biodiversity in the Chalus River, Mazandaran Province

This study aimed to investigate macroinvertebrates biodiversity indices in Chalus River in Mazandaran province and the impact of spring floods on these indices during spring and summer in 2015. Environmental parameters including daily discharge data during 2014-2015, temperature, dissolved oxygen, nitrate, phosphate, pH, TDS and EC were measured in river branches and main channel of the river a...
