detention rockfill dams are an easy and common tool for flood control. due to their coarse pores, the flow in void spaces is turbulent and non-darcy. different relationships introduced by researchers are used to define the hydraulics of the flow within the rockfill materials. the present research is aimed at gaining a better understanding of the differ-ence among these relationships and the sou...

Flood-search on-demand routing has received considerable interest for its application to mobile ad hoc networks. To alleviate the effects of flooding the network with control packets to discover a route, the concept of an expanding ring search (ERS) has been proposed elsewhere for reducing the packet transmission overhead of the route discovery process. Essentially, ERS consists of incrementall...

Abstract We analyzed the characteristics of main karstic/non-karst reaches Lijiang River to uncover causes behind different flood behaviors by providing a better understanding formation. Having 63 years rainfall-runoff data and applying HEC-HMS model, geo/hydrological features were investigated. The available reservoir capacity karts (ARCK) was included through soil moisture accounting loss ass...

We present a new packet filtering scheme, which is traffic-smart to defend against network worms and flood attacks. The scheme prevents malicious hackers from orchestrating DDoS flooding attacks on any IP-based public network. All packets from each IP source are counted and timed during their life cycles. Special IP counters and timers are used to support the filtering process. This new approac...

12 A widely used land surface model, the Variable Infiltration Capacity (VIC) model, is coupled 13 with a newly developed hierarchical dominant river tracing-based runoff-routing model to form 14 the Dominant river tracing-Routing Integrated with VIC Environment (DRIVE) model, which 15 serves as the new core of the real-time Global Flood Monitoring System (GFMS). The GFMS 16 uses real-time sate...

The Social Query Model (SQM) has been proposed in the literature for distributed search and routing over social networks. In this paper, we adapt SQM and the associated distributed query routing algorithm to a novel application domain – wireless sensor networks (WSNs). WSNs are nowadays routinely used for measuring various ambient properties (e.g., temperature, pressure) in uncontrolled environ...
