River gravel sieved into 25 to 50 mm and 50 to 75 mm in diameter were used to construct the rockfill embankments in the water flume. Six rockfill embankments were constructed by changing rock particle size, slopes and length of the embankment, and tested with rising upstream water level. A width and a height of the rockfill embankment were 50 cm and about 50 cm, respectively. The discharge of flow through the rockfill mbankment was summarized and tabulated with the upstream water level. The free surface of flow within the rockfill embankment was observed and drawn in a figure. Some typical examples of the stage-discharge rating curve were given to show a non-linear increase of the flow discharge with rise of upstream water level. Results of the laboratory water flume test given in this report may be applied to find out parameters which control the non-linear behavior of flow through rockfill. Once such the flow parameters are deter- mined, the flow transmissibility of the rockfill structure consisting of river gravel up to about 100 mm in diameter can be predicted accurately without any consideration of a scale effect of void structure and rock particle size on the flow.", "subitem_description_type": "Abstract"}, {"subitem_description":
