The paper presents two approaches used independently to estimate river discharge during an ice jam on the Yukon River near Dawson City. One method entailed the use of large-scale particle image velocimetry to obtain surface velocities, which were extrapolated and integrated to yield a discharge. Videotaping of ice-floe drift comprised the measurement method used for the large-scale particle image velocimetry. The second approach entailed numerical simulations performed with a 1-D ice-jam profile model (ICEJAM). The numerical model incorporates an "island-compensation" technique developed to take into account the difficulty of using 1-D ice-jam profile models to simulate accurately channels with two-dimensional features such as islands and bars. The two approaches yielded closely comparable estimates of river discharge.Key words: discharge, velocity, measurement, river, ice, jam, particle, image, velocimetry, islands.

Ambon City is a region consisting of hilly areas and steep slopes with diverse river characteristics. Research has been carried out in the Wae Ruhu watershed in Ambon City which starts from upstream (water catchment) to downstream. This study aims to determine the magnitude of river discharge and sediment discharge in the Wae Ruhu watershed. This research was conducted in several stages including, secondary data collection, research location survey, preparation of research tools and materials as well as field data retrieval processes which included tracking coordinates at each station point and entire watershed, calculation of river flow velocity, river geometry measurements, and sampling sediment. The results showed that the average river discharge in the Wae watershed in the year 2018 was 1.24 m3 / s, and the average sediment discharge was 6.27 kg / s. From the results of this study and the field observations proposed for flood prevention and the rate of sediment movement are the construction of cliffs with sheet pile and gabions.

High Concentrations

In the Mezen bay and estuaries Mezen and Kuloy can be high concentrations of mud suspension there, involving the formation at times mobile suspensions and settled mud. Within estuaries the river water is mixed with the sea water by the action of tidal motions, by waves on the sea surface and by the river discharge forcing its way to the sea. Nearly all shallow tidal estuaries, where currents exceed about 1,0m s-1 and where sand is present, have sand waves. Sand waves have a variety of cross-sectional and plan forms.
