3-D aerial and underwater sensor networks have found various applications in natural habitat monitoring, weather/earthquake forecast, terrorist intrusion detection, and homeland security. The resource-constrained and dynamic nature of such networks has made the stateless routing protocol with only local information a preferable choice. However, most of the existing routing protocols require sen...

Assimilating real time sensor into a running simulation model can improve simulation results for simulating large-scale spatial temporal systems such as wildfire, road traffic and flood. Particle filters are important methods to support data assimilation. While particle filters can work effectively with sophisticated simulation models, they have high computation cost due to the large number of ...

Abstract. Backwater effects in surface water streams and on adjacent lowland areas caused by mostly complex drainage flow control structures are not directly computed with hydrological approaches yet. A solution to this weakness modelling is presented article. The developed method enables transfer of discharges into levels calculation backwater volume routing along balancing level slopes. imple...

In nature of the transmission medium the broadcast, Wireless sensor networks are vulnerable to security attacks. The nodes are placed in a hostile or dangerous environment where they are not tangibly safe in the MANETs. In many application, the data obtained from the sensing nodes need a false, or malicious node could intercept private information or could send false messages to nodes in the ne...

Reservoir routing is often conducted with the stage-storage curve of the storage facility. Often at a planning stage, little hydraulic information about the storage facility is known yet. Therefore, a performance curve such as the storage-outflow curve needs to be developed from hydrologic information without detail basin geometry and outlet hydraulics. This paper presents a hydrology based pro...

In this study, a framework to circumvent the difficulties in selecting proper flood routing method was established by employing two different multi-criteria decision analysis (MCDA) tools, namely, TOPSIS and PROMETHEE, with definite decisive criteria such as error metrics, number of model parameters, background, under three scenarios. For eight distinct datasets, parameters 10 Muskingum models ...
