Floods have become more severe and frequent as a result of climate change around the world, posing hazard to public safety economic development. This study investigates use distributed hydrological models in flash flood risk management small watershed Hazara, Pakistan, with goal improving Pakistan's early warning lead time. First, HEC-HMS model was built using geographic data river network's st...

In this study both data of land use and cover were compared for selected period time it is obvious that urban area significantly increased in Saline River watershed, Arkansas, USA. For hydrologic studies analysis WMS 8.1 program was used to delineate the watershed other processes. further analysis, HEC-HMS analyze results hydrographs peak flows. Results show there impact processes due urbanizat...

Flooding is one of the most devastating natural disasters occurring annually in the Philippines. A call for a solution for this malady is very challenging as well as crucial to be addressed. Mapping flood hazard is an effective tool in determining the extent and depth of floods associated with hazard level in specified areas that need to be prioritized during flood occurrences. Precedent to the...

In this study, we conducted flood mapping of a hypothetical dam break by coupling the Hydrologic Engineering Center’s Modeling System (HEC-HMS) and River Analysis (HEC-RAS) models under different return periods inflow. This study is presented as case on Kesem embankment in Ethiopia. Hourly hydrological meteorological data high-resolution land surface datasets were used to simulate design floods...

A different usability design approach is needed for the emerging class of home infotainment appliances, collectively referred to as the home media station (HMS). Mass-media theory, consumer electronics engineering, content creation and content distribution play a major role towards the human-centered design of home media appliances. Different audience behavior factors, such as the attention spa...

An important current trend for the ACT-R community is to apply cognitive modelling to real world problems like HCI (Byrne 2001) or human machine interaction (Gluck 2002). Important developments of the architecture that are necessary to do so are PM for integration to the task environment and new ways of goal management. An area that still needs attention is timing for operating human-machine sy...

One of the long-standing problems in antenna engineering is the realization of highly directive beams using low-profile devices. In this paper, we provide a solution to this problem by means of Huygens' metasurfaces (HMSs), based on the equivalence principle. This principle states that a given excitation can be transformed to a desirable aperture field by inducing suitable electric and (equival...
