    Abstract. This study aims at evaluating the performances of flash-flood forecasts issued from deterministic and ensemble meteorological prognostic systems. The hydrometeorological modeling chain includes the Weather Research and Forecasting Model (WRF) forcing the rainfall-runoff model MARINE dedicated to flash floods. Two distinct ensemble prediction systems accounting for (i) perturbed. ResearchGate is a network dedicated to science and research. Connect, collaborate and discover scientific publications, jobs and conferences. All for free.

      Owing to the nature of the search, some flash flood events may not be included, especially for countries where not much information is available. As detailed in the following, long‐term evaluation was performed from December to November During this 1 year period, 71 flash flood events were reported. Analysing the outputs of ERIC. The Generalized Multipole Technique is a surface-based method to find the solution of a boundary-value problem for a given differential equation by expanding the fields in terms of fundamental or other singular solutions of this equation.

    Natural language processing (NLP) portrays a vital role in the research of emerging technologies. It includes sentiment analysis, speech recognition, text classification, machine translation, question answering, among others. If you have watched any webinar or online talks of computer science pioneer Andrew NG, you will notice that he always asks AI and ML enthusiasts to read research papers. 7 Evaluation of the Sulphur Mountain Radar and Flash Flood Warnings in Los Angeles and Ventura Counties 91– 8 Potential Improvements in Flash Flood Warnings – 9 .

[Leo R Beard; United States. National Weather Service.]. In the US, for the flash flood guidance (FFG)-based flash flood warnings and watches issued by National Weather Service (NWS), many studies have focused on derivation of the geomorphological and climatological instantaneous unit hydrograph, estimation of the threshold runoff, development of geographic information system (GIS)-based procedures Cited by:   This watershed is known as one of the most affected regions by floods in Iran (Safaripour et al., ), which experienced many tomore than large and small floods occurred in this watershed (Jannati, ).For example, during the flood that occurred on 11 Augustthe Gorganroud discharge reached about m 3, and the width of the river increased from Cited by:   While additional flash flood indices have been previously proposed, such as the Flash Flood (FF) Index from Davis () (published in conference proceedings) and the Flash Flood Potential Index (FFPI) from Smith (), the foundation of such indices were developed despite the caveats listed above and therefore have some inherent complications Cited by: It shows the example in the book "Applied Hydrology" by Chow, Maidment, and Mays, example, page The only difference in the sheet that the Horton method is.

The Unified Flash Flood Database released by the Hydrometeorology and Remote Sensing (HyDROS) group at the University of Oklahoma is a curated database of flooding information from a variety of sources such as gauge measurements of streamflow by USGS, flash flooding reports in the NWS Storm Events Database, and public survey responses on flash.

This study deals with the evaluation of flash flood. Recognizing the flash flood potential of the drainage basins is important for reducing the associated damages.

In this study, multiple morphometric parameters effecting runoff volume, flow velocity, and water depth were evaluated for understanding the flash flood susceptibility of thirteen watersheds in SE Bangladesh. The infrastructure and buildings are deliberately shown in a generalized way, as is common with scale maps.

In chapter 6 of this report, a quality analysis is done based on a visual inspection and evaluation by the stakeholders in this project. Also the results are compared to two detailed flood hazard analysis projects that were done. Therefore, it is urgent for flash flood susceptibility maps to be developed to delineate flood-prone areas.

These maps would help the authorities, planners, and decision makers to make rapid assessments and take appropriate actions to reduce and minimize the consequences of potential. The books covered several topics including evaluation of drainage basins, early warning systems, flash floods investigations, hydrologic simulation, GIS and flash floods, environmental flash.

Carpenter et al. () discuss four possible methods for computing Thresh-R based on two ways to estimate a catchment’s threshold flow that results in flooding and two ways to estimate a catchment’s linear response to rainfall.

Here, we focus on the methods used operationally by the NWS to derive FFG values. Thresh-R (in length units) is computed by dividing an estimate of bankfull.

To determine the risk of flash floods in a given area, one needs to 1) assess the nature and extent of the potential flash floods (flash flood hazard assessment) – see also Methodology Book chapter - and 2) evaluate the existing conditions of vulnerability (exposure and vulnerability assessment) – see also chapter 7 of the Use Case book.

The early-warning model for flash floods is based on a hydrological and geomorphological concept connected to the river basin, with the principle that flash floods will only occur where there is a high potential risk and when rainfall exceeds the threshold.

In the model used to build flash-floods risk maps, the parameters of the basin are analyzed and evaluated and the weight is determined. The importance of identifying the areas vulnerable for both floods and flash-floods is an important component of risk management.

The assessment of vulnerable areas is a major challenge in the scientific world. The aim of this study is to provide a methodology-oriented study of how to identify the areas vulnerable to floods and flash-floods in the Buzău river catchment by computing two.

Generalized dynamics control is a new concept, and is the scientific study of motion, force, and energy, which combines vehicle dynamics control (VDC) and energy-management system control. Moreover, the structure optimization and generalized dynamics control can be divided into five parts.Elkhrachy, I.
