Experimental videos in studying the influences of dry- and wet-bed downstream conditions on dam break multiphase flood waves in a reservoir with 20 cm sediment depth (67.7% silted-up)
Experimental videos:
Herein, 24 distinct video files have been presented which related to dam break multiphase flood shock wave experiments, performed in the Shiraz University, Civil and Environmental Engineering Department’s Hydraulic Lab (Shiraz, Iran). The initial upstream sediment depth was 20 cm which makes the upstream reservoir 67.7% silted-up with respect to the total 30 cm height of the reservoir. Different initial downstream conditions have also been considered including dry-bed downstream and wet-bed downstream with different levels of standing water; 2 cm, 4 cm and 5 cm.
Considering three cameras which covered length of the flume, 4 different dam break scenarios and 2 repetitions conducted for each test, a total of 24 videos collected which presented in this document.

Experimental videos in scrutinizing multiphase shock flood wave over different downstream initial conditions
Experimental videos:
Herein, 111 distinct video files have been presented which related to dam-break multiphase flood shock wave experiments, performed in the Shiraz University, Civil and Environmental Engineering Department’s Hydraulic Lab (Shiraz, Iran). A clear water reservoir (without sediment) as well as 2 different sediment depths (0.03 and 0.075 m) were considered as initial upstream conditions to investigate multiphase flash flood characteristics. These 3 initial upstream conditions make the upstream reservoir 0% to 25% deposited with sedimentation (with respect to the total 30 cm height of the reservoir). Six different initial downstream conditions have also been considered. Semi-circular obstacles (‘humps’) of two different cross-sections (0.045 m or 0.075 m) were stiffly fixed to the bottom of the flume’s downstream bed and further fixed to the sides of the flume using rubber bands, 1 m downstream from the gate (dam). Dam-break scenarios in the smooth downstream bed (no obstacle) were used to acquire a basis of comparison for other downstream conditions. Additionally, wet-bed downstream conditions with three different standing water initial heights (0.02, 0.04 and 0.5 m) were considered as initial downstream conditions to investigate multiphase flash flood characteristics. Considering three cameras which covered length of the flume, 18 different dam break scenarios and 2 or 3 repetitions conducted for each test, a total of 111 videos collected from 37 distinct experiments which presented in this document.

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.
