“…It is commonly used for the preliminary design and sizing of stormwater management systems. It is used to estimate the peak flow rate of stormwater runoff from a given catchment considering the land use and surface characteristics, and the rainfall intensity obtained from local weather records and using rainfall intensity-duration-frequency (IDF) curves specific to the study area [51]. In addition, there are various hydrologic models available that simulate the rainfall-runoff process.…”

Urban storm drainage is fundamental for the well-being of the population of cities with torrential rainfall regimes because it is essential for the rapid and safe disposal of stormwater runoff. However, it is not uncommon for hydrological studies to determine the design flow of storm drainage works carried out in the same urban basin using different criteria depending on the experience of the person performing them. This can represent a problem when integrating and reviewing the results of hydrological studies carried out by different hydrologists. To address this problem, we propose a methodology consisting of methods used by various authors to determine the design flow rate in urban hydrologic studies. We suggest using a novel method to delineate urban basins based on photogrammetry obtained through flights with unmanned aerial vehicles. Subsequently, the necessary parameters are obtained to define the intensity–duration–return period curves, the runoff coefficients, and finally the design flow rate. The contribution of this article is technological. In this sense, a new methodology is proposed that applies existing knowledge to solve a practical problem observed in the field of urban hydrology and storm drainage. The case study is a basin with frequent flooding located in Culiacan, Mexico.

“…As an initial test for sediment bulking or surging of the ow that may explain the sudden increase in channel erosion and widening, we calculated a ratio of eld-measured to runoff-based peak discharge, C (e.g., Kean et al, 2016). Flood ows can have a range of C values between 0 and 1 (e.g., Lapides et al, 2021). Due to conservation of mass, this ratio cannot exceed 1 in the absence of substantial sediment bulking or surge dynamics and can be used as a check on indirect measurements of ood discharge (e.g., Moody, 2016).…”

Channel widening is a major hazard during floods, particularly in confined mountainous catchments where roads and buildings compete for space with river channels. Flood-induced channel widening is also an important process in eroding and shaping the landscape. However, channel widening during floods is not well understood and not always explained by hydraulic variables alone, with implications for flood risk management. Floods in mountainous regions often coincide with landslides triggered by heavy rainfall on steep valley sides. Whilst the long-term impact of increased sediment supply on channel widening is well established, landslide-channel interactions at the event timescale are not well known or documented. Here we demonstrate with an example from the Great Colorado Flood in 2013, a 1000-yr precipitation event that induced a 200-yr flood, and 100-yrs of erosion, how landslide-channel feedbacks can substantially amplify channel widening and flood risk. We use a combination of field analysis and multiphase flow modeling to document landslide-channel interaction during the flood event in which sediment delivered by landslides temporarily dammed the channel before failing and bulking the flow with sediment resulting in large channel widening. We propose that such landslide-flood interactions will become increasingly important to account for in flood hazard assessment as flooding and landsliding increase with extreme rainfall under climate change.

“…Nevertheless, the tables present the specificity of the drainage basins for which they were developed. Therefore, reference tables are generalist and may not cover specific cases, requiring further studies and updating of technical references (Lapides;Sytsma;Thompson, 2021;Young;Mcenroe;Rome, 2009).…”

Surface runoff monitoring is important for the sustainable management of global water resources. Obtaining a practical and inexpensive method for collecting data in the field can help to better understand surface runoff and its effects, necessary for the management of watersheds. This study sought to elaborate the calibration curves of the ultrasonic sensor due to temperature variability, verifying the inaccuracy of the distance between objects and the sensor, and determining the feasibility of using low-cost sensors in an in-loco experiment installed on Parshall flumes. The experiment was conducted on the Experimental Farm of the Federal University of Grande Dourados, Dourados, MS, Brazil. The data were collected by twelve HC-SR04 ultrasonic distance sensors , which were coupled to a data acquisition system composed of an expansion board connected to a Raspberry minicomputer. Sensor calibration using temperature data resulted in the error correction of ± 8.0 mm of distance reading. On the other hand, the R2 of the comparison curves between sensor and control system (laser distance meter and ruler in the flume) resulted in high values (above 0.95), showing the feasibility of its use and meeting the specifications for use in the field subject to weather conditions. This study demonstrates the performance of ultrasonic sensors as a potential for new application to evaluate surface runoff aiming to propose new runoff coefficients.
