Abstract:
... This study aims to present an accurate and efficient finite volume approach for overland flow modelling in rural and urban areas through solving the two-dimensional shallow water equations. The proposed approach introduces a hybrid procedure that utilizes the sharpness of discontinuity to identify flow conditions in the entire computational domain, and then a low-accuracy/high-efficiency scheme (t ...

Abstract:
... The nonlinear relationship between runoff and time is a major challenge in hydrological forecasting. It is important to improve the prediction accuracy of models for disaster mitigation, thus allowing decision makers to make decisions in advance. This paper proposes a method called joint error correction. First, we cluster the initial prediction errors. Then, the moving average method is used to s ...

Abstract:
... Long-term droughts observed in southern Australia have changed relationships between annual rainfall and runoff and tested some of the assumptions implicit in rainfall–runoff models used in these areas. Predictive confidence across these periods is when low using the more commonly used rainfall–runoff models. Here we modified the GR4J model to better represent surface water–groundwater connection ...

Abstract:
... A variety of hydrological models is currently available. Many of those employ physically based formulations to account for the complexity and spatial heterogeneity of natural processes. In turn, they require a substantial amount of spatial data, which may not always be available at sufficient quality. Recently, a top-down approach for distributed rainfall-runoff modelling has been developed, which ...

Abstract:
... The storage function model (SFM) is a rainfall–runoff model widely used in Korea for flood forecasting and warning systems. The traditional equations for parameter estimation are based on observed data under limited conditions, and so it is difficult to sensitively consider the factors affecting actual runoff. The aim of this study is to develop synthetic equations for SFM parameter estimation tha ...

Abstract:
... Hydrologic processes in depression-dominated areas are controlled by the spatial distribution of surface depressions and their dynamic hydrologic connectivity. Existing hydrologic models often utilize lumped ways to handle depressions, and hence their spatial features are lost in this simplification process.

Forecasting floods in urban areas during a heavy rainfall is the aim of every early warning system. 2D-models produce the most accurate flood maps, but they are practically useless as quasi real-time tools, because their run times are comparable to times of propagation of floods. Run times of 1D-model are of tens of seconds, but their predictions lack accuracy and many useful indicators of flood s ...
