“…Thus, this task should be always accompanied by the best engineering judgement, which also involves an assessment of equations. Hydrologic and hydraulic (H&H) analysis for stormwater management such as dam-breach analyses; flood-prone area delineation and flood risk analyses; stream restoration; erosion, sediment, and contaminant load estimation, and conventional and sustainable drainage system design must be as accurate as possible when estimating all variables [10,80,81,[83][84][85][86]. This includes the estimation of the Tc, which becomes relevant when using rainfall-runoff models and software programs requiring such input for the design runoff computation (e.g., rational method, HEC-HMS, WinTR-55, WinTR-20, StormCAD ® /SewerCAD ® ).…”

Assessing the Performance of Different Time of Concentration Equations in Urban Ungauged Watersheds: Case Study of Cartagena de Indias, Colombia

In ungauged watersheds, the estimation of the time of concentration (Tc) is always a challenging task due to the intrinsic uncertainty involved when making assumptions. Given that Tc is one of the main inputs in a hydrological analysis for the design of hydraulic structures for stormwater management, ten equations (including one proposed in several local studies) and two Tc methodologies (overland flow time plus channel flow time) were used to compute the Tc in fifteen urban ungauged watersheds, located in Cartagena de Indias (Colombia), with different area sizes and slopes to statistically assess their performance against the value obtained via the Natural Resources Conservation Service (NRCS) velocity method (assumed to be the true value). According to the Nash–Sutcliffe efficiency index, none of the equations proved to be reliable in all watersheds as only four equations predicted the Tc value in 53% of the cases. In addition, based on the percent bias, all equations tended to significantly over- or underestimate the Tc, which affects the quantification of the runoff volume necessary for, among others, the implementation of best management practices for watershed management (e.g., conventional and/or sustainable drainage system design), flood-prone area delineation and flood risk analyses, urban planning, and stream restoration.

“…Their main focus is to examine the arrival time of flooding from the dam to the residential area downstream providing early warning for people living downstream. HOOGESTRAAT [20] presents a detailed technical discussion of using HEC-RAS software for modelling dam failures. Some of the approaches such as level pool routing and 2D flow area in this technical report are experimented with for dam-break simulation in this study.…”

The Brumadinho dam disaster occurred on the 25 January, 2019 when Dam I, an upstream tailings dam at the Corrego do Feijao iron ore mine, 9 kilometres (5.6 mi) east of Brumadinho, Minas Gerais, Brazil, suffered a catastrophic failure [1]. Over 248 people died and over $2.88 billion worth of property were lost or damaged [2] [3] due to the subsequent mud flow and flooding. This is merely 4 years after the previous Mariana dam break affecting over 1 million people downstream due to iron ore mining waste flowing into river basin [4]. To prevent a similar tragedy from reoccurring, it's useful to examine the cause of the Brumadinho dam break and compare observations with model simulations. HEC-RAS, developed by US Army Corps of Engineers [5] [6], is used to model the mud flow from the Brumadinho dam break based on the NASA SRTM elevation dataset over Brazil [7]. The extent of the mud flow from the HEC-RAS simulation matches the actual flooding due to the dam break. This simulation technique can later be used for future dam collapse predictions.

“…The Geospatial Hydrologic Modeling Extension (HEC-GeoHMS) is a public-domain software package for use with Geographical Information Systems (GIS), GeoHMS ArcView and Spatial Analysis to develop several hydrological modeling inputs. After analyzing the information of the Digital Elevation Model (DEM), HEC-GeoHMS transforms the drainage paths and watershed boundaries into a hydrologic data structure that represents the watershed response to rainfall [6]. An important feature of the HEC-GeoHMS model is the assignment of the curve numbers (CN), which are related to the land use/land cover and soil type of the Al-Adhaim catchment.…”

“…The coefficient of determination R 2 was 0.93 indicating that the model was appropriate for hydrological simulations. HEC-HMS and GIS were successfully used to simulate the rainfall-runoff process in the Karun river basin in Iran [11], as well as the inflow designed floods and dam breach hydraulic analyses of four reservoirs in the Black Hills, South Dakota [6]. Other examples include the modeling of the watershed in Ahvaz, Iran [12,13], the simulation of the runoff process for the adjoining areas of the Lagos Island and Eti-Osa Local Government Areas and the assessment of the influence of different levels of watershed spatial discretization on the HEC-HMS model's performance for the Uberaba River Basin region [14].…”

Rainfall-Runoff Modeling Using the HEC-HMS Model for the Al-Adhaim River Catchment, Northern Iraq

It has become necessary to estimate the quantities of runoff by knowing the amount of rainfall to calculate the required quantities of water storage in reservoirs and to determine the likelihood of flooding. The present study deals with the development of a hydrological model named Hydrologic Engineering Center (HEC-HMS), which uses Digital Elevation Models (DEM). This hydrological model was used by means of the Geospatial Hydrologic Modeling Extension (HEC-GeoHMS) and Geographical Information Systems (GIS) to identify the discharge of the Al-Adhaim River catchment and embankment dam in Iraq by simulated rainfall-runoff processes. The meteorological models were developed within the HEC-HMS from the recorded daily rainfall data for the hydrological years 2015 to 2018. The control specifications were defined for the specified period and one day time step. The Soil Conservation Service-Curve number (SCS-CN), SCS Unit Hydrograph and Muskingum methods were used for loss, transformation and routing calculations, respectively. The model was simulated for two years for calibration and one year for verification of the daily rainfall values. The results showed that both observed and simulated hydrographs were highly correlated. The model’s performance was evaluated by using a coefficient of determination of 90% for calibration and verification. The dam’s discharge for the considered period was successfully simulated but slightly overestimated. The results indicated that the model is suitable for hydrological simulations in the Al-Adhaim river catchment.
