TREX is a physically-based, distributed model that simulates flash floods, sediment transport, and chemical transport and fate processes at the watershed scale. Basic processes in TREX include precipitation, interception, infiltration, surface runoff, and channel flow, erosion and deposition of upland soil and channel bed sediment, and chemical transport. TREX is readily coupled with standard G...

In this paper, we present the Flash flooding protocol that exploits the capture effect to produce low-latency network floods. The capture effect is the ability of some radios to correctly receive one of several concurrently transmitted messages, even if the received strengths of the two messages are almost the same. We exploit this phenomenon in a network flooding scenario by allowing nodes to ...

This study aims to characterise the rainfall exceptionality and the meteorological context of the 20 February 2010 flash-floods in Madeira (Portugal). Daily and hourly precipitation records from the available rain-gauge station networks are evaluated in order to reconstitute the temporal evolution of the rainstorm, as its geographic incidence, contributing to understand the flash-flood dynamics...

Flash flood induced by severe convection is the hydrometeorological phenomenon that is very difficult to forecast. However, the implementation of radar measurements , especially radar-based Quantitative Precipitation Estimate (QPE) and/or radar-based quantitative Precipitation Nowcast (QPN) can improve this situation. If the radar is able to capture the development of severe convection and can ...

The standard conceptual HBV model was originally developed with daily data and is normally operated on daily time step. But many floods in Slovenia are usually flash floods as result of intense frontal precipitation combined with orographic enhancement. Peak discharges are maintained only for hours or even minutes. To use the HBV model for flash flood forecasting, the version of HBV-96 has been...

Flash floods are the most dangerous processes in Seine-Maritime (northern France) due to their sudden onset and rapid rising time. Such floods shortly follow high rainfall, ranging from 50 to up to 100 mm in less than 6 hours, and occur in small (< 20 km2) and dry valleys, in which a surge rushes down through the main valley just a few minutes after rains have peaked. Phenomena currently produc...

The interaction of wind and water in semiarid and arid areas usually leads to low-frequency flash flood events in desert rivers, which have adverse effects on river systems and ecology. In arid zones, many aeolian dune-fields terminate in stream channels and deliver aeolian sand to the channels. Although aeolian processes are common to many desert rivers, whether the aeolian processes contribut...

There is no doubt that it world-class innovative scientific research in advanced technology. This on flood unique, which will open many doors for current and future generations. Rain falling from the sky to earth certainly a blessing mankind but when flash occurs with human controlled technology, painful all. Studies have shown misuse of satellite technology has caused massive damage man-made f...
