Stream channel recovery from recent large floods in northern California involves a sequence of processes, including degradation of streambeds to stable levels, narrowing of channels, and accentuation of riffle-pool sequences. Most channels have degraded but remain widened because hillslope encroachment and establishment of riparian groves conducive to sediment deposition have not yet caused str...

Floods at Carlsbad in 1890.?The news of tlie destructive floods at Carlsbad in November 1890, was heard with dismay and the greatest regret by all admirers of the " Gem of Bohemia and the Queen of all bathing places," as it is called by the patriotic inhabitants. The therapeutic properties of its mineral springs are so valuable that every effort will be made to restore to its former beauty this...

Introduction Coastal floods account for a large proportion of the damage to life and property due to natural disasters world-wide. Out of the 15 greatest natural disasters in the world in terms of monetary losses between 2004 and 2008, 14 were coastal (Kron 2008). However, despite the enormity of a particular flood event, people often return to a flood-prone area after a disaster (Cigler 2007; ...

DNS amplification has been instrumental in over 34% of high-volume network DDoS attacks, with some floods exceeding 300Gbps. Today’s best practices require Internet-wide cooperation and have been unable to prevent these attacks. In this work, we investigate whether these best practices can eliminate DNS amplification attacks and characterize what threats remain. In particular, we study roughly ...

the main aim of the current paper is to discuss the important effective variables, particularly synoptic patterns, in creating flood in masoule basin using flood discharge data in komadoul station during 20 year period (1984-2003). to achieve the aim, daily average and instantaneous maximum of discharge in mentioned station were used. data accuracy was done using the data for chomesghal station...

Out of all the natural disasters, floods are the most common in both developed and developing countries, accounting for approximately 40% of all natural disasters [1,2]. Flooding has severe implications on human health before, during, and after the onset of a flood. Southeast Asia is a region that is especially prone to frequent and severe natural disasters [3]. The Association of Southeast Asi...

Riparian cottonwood (Populus deltoides) forests form the one of the most extensive deciduous forest ecosystems in arid regions of the western United States. However, cottonwood populations are threatened by flow alteration and channel degradation caused by dams, water diversions, and groundwater pumping. We developed a stochastic, densitydependent, population model to (1) consolidate informatio...

During the last deglaciation of North America, huge proglacial lakes formed along the southern margin of the Laurentide Ice Sheet. The largest of these was glacial Lake Agassiz, which formed about 11:7 C kyr and drained into Hudson Bay about 7:7 C kyr ð8:45 cal kyrÞ: Overflow from these lakes was variably directed to the Mississippi, St. Lawrence and Mackenzie drainage systems and it is thought...
