Experimental dataset on water levels in the study of flash flood wave without sediment (clear water) over bumpy downstream
Experimental dataset of free surface water level: In this file, all water level data associated with 3 different dam break scenarios were extracted from high-quality experimental video images. The dataset are collected, classified and presented a total of 3 tables in 3 categories based on the radiuses of downstream semi-circular obstacles; 0, 4.5 and 7.5 cm. Initial upstream sediment depth was 0 cm and the upstream reservoir was filled-up with clear water. Table 1, presents the free surface water level data at 20 different locations along the flume and 15 snap times after the dam break, while the radius of downstream semi-circular obstacle was 4.5 cm. Table 2, provides the free surface water level data at all abovementioned sections and snap times while the radius of downstream semi-circular obstacle was 7.5 cm. Table 3, presents the free surface water level data at all abovementioned sections and snap times while there were no obstacles in the dam downstream. The unit that has been used to measure data is centimeter and the abbreviation of O_r is the radiuses of downstream semi-circular obstacles. 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.
