Description

Experimental data collection In this file, all sediment depth data associated with 20 different silted-up dam break scenarios were extracted from high-quality experimental video images. The dataset are collected, classified and presented a total of 20 distinct tables in 5 categories based on initial upstream sediment depth; 15 cm, 17.5 cm, 20 cm, 22 cm and 24 cm. Tables 1-4, present the sediment depth data at 20 different locations along the flume and 15 snap times after the dam break, while the initial upstream sediment depth is 15 cm (50% of the reservoir height). Dry- and wet-bed initial downstream condition with 2 cm, 4 cm and 5 cm standing water depth are detailed in Table 1-4, respectively. Table 5-8 provide the sediment depth data at all abovementioned sections and snap times while the initial upstream sediment depth is 17.5 cm (58% of the reservoir height), and dry- or wet-bed downstream with 2 cm, 4 cm and 5 cm standing water depth were considered as initial downstream conditions, respectively. Table 9-12 show the sediment depth data at all sections and snap times while the initial upstream sediment depth is 20 cm (67% of the reservoir height), and dry- or wet-bed downstream with 2 cm, 4 cm and 5 cm standing water depth were considered as initial downstream conditions, respectively. Table 13-16 provide the sediment depth data at all sections and snap times while the initial upstream sediment depth is 22 cm (73% of the reservoir height), and dry- or wet-bed downstream with 2 cm, 4 cm and 5 cm standing water depth were considered as initial downstream conditions, respectively. Table 17-20 show the sediment depth data at all sections and snap times while the initial upstream sediment depth is 24 cm (80% of the reservoir height), and dry- or wet-bed downstream with 2 cm, 4 cm and 5 cm standing water depth were considered as initial downstream conditions, respectively.
