Reservoir Routing on Double-Peak Design Flood
This work investigates the routing effect provided by an artificial reservoir to a double-peak flood of a given return period. The present paper introduces a dimensionless form of the reservoir balance equation that describes the hydrologic-hydraulic processes that may occur and allows for the evaluation of the reservoir routing coefficient (RC). Exploiting this equation, an extensive sensitivi...
متن کاملBivariate Return Period for Design Hyetograph and Relationship with T-Year Design Flood Peak
This study focuses on the return period evaluation for design hyetographs, which is usually estimated by adopting a univariate statistical approach. Joint Return Period (JRP) and copula-based multivariate analysis are used in this work to better define T-year synthetic rainfall patterns which can be used as input for design flood peak estimation by means of hydrological simulation involving rai...
متن کاملProbabilistic flood hydrographs using Monte Carlo simulation: potential impact to flood inundation mapping
Flood inundation modelling generally involves two steps. The first involves the use of a hydrologic model, such as RORB, to estimate the design flood hydrograph for a given design storm event. These models require several inputs, such as design rainfalls (i.e. duration, intensity & temporal pattern), losses, baseflow and routing parameters; each of which has an associated degree of uncertainty ...
متن کاملSimulation of Design Flood Hydrographs in Aydooghmush Basin with HEC-HMS Model
Hydrological models for evaluating and predicting the amount of available water in basins, flood frequency analysis, and developing strategies to deal with destructive floods are expanding daily. In this study, HEC-GeoHMS and Arc Hydro extensions in ArcGIS software and the HEC-HMS model were used to simulate design flood hydrographs in the Aydooghmush basin in the northwest of Iran. SCS-CN, SCS...
متن کاملPreparation of flood sensitivity map using SVM model and the impact of green city development on the increase of flood flow peak and the resulting damage
Aims: The expansion of cities, especially cities that have seen abnormal growth due to economic, social, and political changes, has caused many problems. It has been found that land-use change, especially urbanization, has greatly affected hydrological characteristics. But in most urban designs, flood forecasting is considered through the type of land use (residential, industrial, etc.) and den...
