Experimental dataset on water levels in the study of dam-break multi-layer shock wave over bumpy downstream while 10 to 25% of the dam reservoir is occupied by sedimentation

Experimental dataset of free surface water level: In this file, all water level data associated with 6 different dam break scenarios were extracted from high-quality experimental video images. The dataset are collected, classified and presented a total of 6 tables in 3 categories based on the radiuses of downstream semi-circular obstacles; 0, 4.5 and 7.5 cm. Initial upstream sediment depths were 3 and 7.5 cm and the upstream reservoir was initially occupied by 10 to 25% sedimentation (in respect to 30 cm height of the upstream reservoir). Tables 1 and 2, present the free surface water level data at 20 different locations along the flume and 15 snap times after the dam break, while initial upstream sediment depths were 3 and 7.5 cm, respectively and the radius of downstream semi-circular obstacle was 4.5 cm. Tables 3 and 4, provide the free surface water level data at all abovementioned sections and snap times while initial upstream sediment depths were 3 and 7.5 cm, respectively and the radius of downstream semi-circular obstacle was 7.5 cm. Tables 5 and 6, present the free surface water level data at all abovementioned sections and snap times while initial upstream sediment depths were 3 and 7.5 cm, respectively and there were no obstacles in the dam downstream. The unit that has been used to measure data is centimeter and the abbreviations including O_r and S_d are the radiuses of downstream semi-circular obstacles and upstream initial sediment depth, respectively. Time also refer to the time snaps after sudden removal of the gate using second as a unit of measurement. It should be noted that the vertical column on the left of the tables indicates the distances of different locations in centimeter from the beginning point of the laboratory flume. So, L column indicates all 20 distinct locations along the flume and their distances from the reservoir beginning in centimeter as a unit of measurement.
