The present study aims to investigate the hydrological response of small coastal watersheds storm events. Areas around Mediterranean Sea are usually characterized by streams with intermittent flows and flash floods common. Firstly, we analyze geomorphological, soil land cover characteristics watershed in order estimate their effect on surface runoff. Furthermore, rainfall an extreme event that ...

Headwater accident is a natural phenomenon that occurs in every flow channel, resulting in tremendous incidents that involve vulnerable lives and destruction of its surroundings. This study focuses on simulation of potential headwater accidents at Lata Kinjang waterfall (Perak, Malaysia) with the aim of understanding the behavior of headwater accidents from the hydraulic aspect. By deploying th...

The physically-based distributed hydrological models play an important role in watershed hydrology. Physical simulation of flow routing depends largely on the field distribution of flow velocity.Terrain analysis studies have previously focused more on the delineation of geomorphologic structures rather than the description of hydraulic factors. As affected by multiple uncertain factors includin...

In this paper, we evaluate by computer simulations the throughput performance of the turbo-coded hybrid ARQ for direct sequence code division multiple access (DS-CDMA) with antenna diversity reception and Rake combining in a frequency selective Rayleigh fading channel. The effect of a range of system parameters and propagation parameters (viz., the frame length, puncturing rate, spreading facto...

Analysis of 41 ERS 1 synthetic aperture radar images and simultaneous ground measurements of discharge for three large braided rivers indicates that the area of active flow on braided river floodplains is primarily a function of discharge. A power law correlation is found between satellite-derived effective width We and discharge Q, where We is the water surface area within a braided reach divi...
