“…Besides HEC-RAS, some researchers have used other models for dam break analysis. One such example is Dam Break Analysis of Thenmala Dam, India using BOSS DAMBRK software to investigate, extent of inundation, flood wave travel time and velocity [25]. Maximum precipitation was evaluated using Gunmel's method while maximum flood was calculated using Clark's method.…”

Dams are vital for production of electricity, storage of water and irrigation purposes but pose a serious risk to the community, if breached. The downstream flood wave propagation, resulting from failure of a dam can subject the population and infrastructure to considerable damage. No matter how low the chances of failure, the cost of failure makes it a higher risk. Mitigation of such risks requires better understanding of the hazard that a dam may pose in case of failure. This study focuses on the effects of flood wave propagation on a fixed bed on the downstream side resulting from sudden dam break. Two conditions are simulated: 1. when the downstream side is open, 2. when the downstream side is closed. It is observed that the flood wave diminishes in velocity and height with increase in time for both cases. For downstream open condition, the flood wave attains maximum height in 2 to 4 sec and maximum velocity within 2 to 5 sec. For downstream closed condition, the flood wave attains maximum height within 5to 10 sec and maximum velocity within 3 to 5 sec. The results obtained from the two-dimensional shallow water equation based numerical model are in close agreementwith the experimental results.

“…Accordingly, the first studies in this regard took place in France at the end of the 19th century, when some solutions were theorized on the problems caused by the earthen dam failure. Subsequently, according to [19], there are two important periods in which significant progress was made: (a) the first period from 1950 to 1990 when many laboratory experiments were performed and the first computerized hydraulic modeling programs were implemented (e.g., DAMBRK '88, BREACH 7/88, DWOPER 8/89, SMPDBK 9/91, MIKE SHE) [20][21][22]; (b) the second period from 1990 to present, when more hydraulic modeling software programs were upgraded (e.g., one-dimensional/twodimensional (1D/2D) HEC-RAS (Hydrologic Engineering Center River Analysis System, developed by USACE HEC, Davis, CA, USA) and determined the improvement of dams failure forecasting [23][24][25][26]. Currently, floods caused by dam-break events still force society to create more upgraded software applications and geographic information system (GIS) tools used for forecasting, prevention, and disaster risk reduction caused by dam failure.…”

Using hydraulic modeling techniques (e.g., one-dimensional/two-dimensional (1D/2D) hydraulic modeling, dam break scenarios) for extracting the flood settings is an important aspect of any action plan for dam failure (APDF) and flood mitigation strategy. For example, the flood hydraulic models and dam break scenario generated based on light detection and ranging (LiDAR)-derived digital elevation models (DEMs) and processed in the dedicated geographic information systems (GIS) and hydraulic modeling software (e.g., HEC-RAS—Hydrologic Engineering Center River Analysis System, developed by USACE HEC, Davis, CA, USA) can improve the flood hazard maps in case of potentially embankment dam failure. In this study, we develop a small-scale conceptual approach using 2D HEC-RAS software according to the three embankment dam break scenarios, LiDAR data (0.5 m spatial resolution), and 2D hydraulic modeling for the Başeu multi-reservoir system which belongs to the Başeu River (NE Romania) including R1—Cal Alb reservoir, R2—Movileni reservoirs, R3—Tătărăşeni reservoirs, R4—Negreni reservoirs, and R5—Hăneşti reservoirs. In order to test the flood control capacity of the Bașeu multi-reservoir system, the Cal Alb (R1) dam break scenario (piping failure) was taken into account. Three 2D stream flow modeling configurations based on R1 inflow rate with a 1% (100 year), 0.5% (500 year), and 0.1% (1000 year) recurrence interval and the water volume which can be accumulated with that specific inflow rate (1% = 10.19 × 106 m3; 0.5% = 12.39 × 106 m3; 0.1% = 17.35 × 106 m3) were computed. The potential flood wave impact was achieved on the basis of different flood severity maps (e.g., flood extent, flood depth, flood velocity, flood hazard) generated for each recurrence interval scenario and highlighted within the built-up area of 27 settlements (S1–S27) located downstream of R1. The results showed that the multi-reservoir system of Bașeu River has an important role in flood mitigation and contributes to the APDF in the context of climate change and the intensification of hydrological hazard manifestation in northeastern Romania.

“…The use of local hydrodynamic models such as Hec-Ras, Lisflood, Mike3 and FLDWV (George & Nair, 2015;Patel et al, 2017) can be considered a robust approach as these models solve the Saint-Venant equations in forms 1D, 2D (Agência Nacional de Águas, 2016b), providing accurate information on peak flows, peak time, and extent of flooded areas at different sites downstream of the dams.…”

In this research study, the MGB-IPH (acronym for Large Scale Model in Portuguese - Modelo de Grandes Bacias) was used to simulate the propagation of a dam breach hydrograph estimated from predictor equations for the Três Marias Hydropower Dam, considered one of the largest in South America. The results of the peak flow, peak time and flood spot were compared with results of the Hec-Ras 5.06 model, typically used for local-scale dam break studies. As for the extent of the flood, a hit rate of 84% and a median error of 2.1 meters deep, along 4,055 km2 of the flooded area downstream was obtained. Maximum errors of 13% were observed in the prediction of the peak flow and of 20% for the peak time in distant locations up to 526 km downstream from the dam, thus establishing itself within the limits of the typical uncertainties associated with dam break studies. Thus, the potential of using this type of approach in previous studies of large dam failures is explored, configuring this method as an alternative to the use of robust or simplified models for determining downstream areas potentially affected by these disasters.
