[1] Isotopic hydrograph separation (IHS) to define sources of event and preevent water during hydrological episodes has greatly improved the understanding of water, solute, and contaminant transport to streams during recent decades. However, the large variation in snowmelt isotopic composition, caused by fractionation during melting, has impeded an accurate separation of streamflow during sprin...

Flood simulation models and hazard maps are only as good as the underlying data against which they are calibrated and tested. However, extreme flood events are by definition rare, so the observational data of flood inundation extent are limited in both quality and quantity. The relative importance of these observational uncertainties has increased now that computing power and accurate lidar sca...

Intense rainstorms are a prevalent feature of current weather. Evidence is presented showing that simulation of flood hydrographs shown to be dominated by subsurface flow requires watershed model parameterisation to vary between periods of different rainstorm intensity, in addition to varying with antecedent basin storage. The data show an emerging global relation between flood response and the...

surat is a highly developed, thickly populated cosmopolitan character city with full of various activities going on day and night. any natural calamity which causes loss of lives to property and infrastructure along with effects on industrial processes going on has serious impact on economy of the state. therefore, it becomes highly necessary that flood events are studied and analyzed properly ...

Denial-of-Service (DoS) flooding attacks have become a serious threat to the reliability of the Internet. Web servers face all kinds of users; some of them engage malicious activities to degrade or completely block network services, such as flooding attacks. As a result, lots of resource and bandwidth on web sites might be wasted. While many approaches exist to filter network-level attacks, the...

Conventional method of identifying areas to be inundated for issuing flood alert require inputs like discharge data, fine resolution digital elevation model (DEM), software for modelling and technically trained manpower to interpret the results meaningfully. Due to poor availability of these inputs, including good network of historical hydrological observations and limitation of time, quick flo...

This paper describes the development of a set of guidelines on the use and integration of digital terrain data for Emergency Risk Management (ERM) planning, specifically in relation to flood hazard. The guidelines were developed by a node of the Cooperative Research Centre for Spatial Information (CRC-SI) at the University of New South Wales (UNSW), Sydney, Australia, in conjunction with NSW Go...

This paper examines Moroccan author Baqqâli’s novel al-TEûfân al-‘Azraq [The Blue Flood, 1976] from the perspective of its use of an artificial intelligence (AI) as a guiding force in a sequestered community. In the novel, the desert refuge for scientists is controlled by a massive computer. The protagonist becomes aware that the AI has become sentient and is planning to use nuclear weapons to ...
