Flood simulation is a complex problem involving large masses of fluid, soil watering, erosion and collision. We will demonstrate the flood simulation of cities were the fluid particles collide with a complex city model. For the fluid simulation we had used Smoothed Particle Hydrodynamics (SPH) method, by which we gained less expensive computation than by using other known methods of water simul...

[email protected] Abstract – Previous studies have shown that irrigation can impact the near-surface climate, but none refer to the differences in the impacts of irrigation types such as flooding and spraying. In this study, we add a novel irrigation module to the recently released community land model 4.0 and simulate irrigation in two ways: first, by spraying water...

The paper presents flood forecasting and simulation system applied to a river flood analysis and risk prediction. An advanced river flood monitoring, modelling and forecasting approach is introduced. It extends the traditional approach based on modelling of river physical processes by integration of different types of models and technologies such as input data clustering and filtering, digital ...

Recently, flood damage by frequent localized downpours in cities is on the increase on account of abnormal climate phenomena and the growth of impermeable areas due to urbanization. This study suggests a method to estimate real-time flood risk on roads for drivers based on the accumulated rainfall. The amount of rainfall of a road link, which is an intensive type, is calculated by using the rev...

This paper gives an eecient simulation to show that dynamic networks are as fast as static ones up to a constant multiplicative factor. That is, any task can be performed in a dynamic asyn-chronous network essentially as fast as in a static synchronous network. The simulation protocol is based on a new approach, perceiving \local-ity" as the key to fast adaptation to changes in network topology...

Tsunamis are able to move large amounts of sediment during their inundation process. However, previous studies conducted to assess tsunami hazard have not considered tsunamiinduced sediment transport in their simulations, although it is possible that morphological adjustments during tsunami inundation increase the levels of hazard. In this paper, we present a model which is able to simulate sed...

An efficient flood alarm system may significantly improve public safety and mitigate damages caused by inundation. Flood forecasting is undoubtedly a challenging field of operational hydrology and a huge literature has been developed over the years. In this paper, we first define ordered ideal intuitionistic fuzzy sets and establish some results on them. Then, we define similarity measures betw...

This paper proposes a complex systems methodology for risk assessment in emergency management and response systems. The methodology is applied to a concrete case, the flood incident management system (FIM) operated by the British Environment Agency. Flood incidents are one category of natural catastrophes, disasters or emergencies. The occurrence of emergencies is determined by the operation of...

When a large group of pedestrians moves around a corner, most pedestrians do not follow the shortest path, which is to stay as close as possible to the inner wall, but try to minimize the travel time. For this they accept to move on a longer path with some distance to the corner, to avoid large densities and by this succeed in maintaining a comparatively high speed. In many models of pedestrian...
