Subglacial floods (jökulhlaups) are well documented as occurring beneath present day glaciers and ice caps. In addition, it is known that massive floods have occurred from ice-dammed lakes proximal to the Laurentide ice sheet during the last ice age, and it has been suggested that at least one such flood below the waning ice sheet was responsible for a dramatic cooling event some 8000 years ago...

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...

The technology follows a sequence of steps: 1) place a confinement template proximal to the disposal structure; 2) drive a primary confinement €I-beam and sheet piling proximal to and below the underground structure and contaminant plume; 3) inject a primary low-cost inorganic polymer below the contaminated geologic media; 4) injectMood the contaminant plume; 5) inject cements and sequestering ...

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 ...

New ports are mostly constructed on low lying coastal areas or shallow coastal waters. The quay wall and terminal yard are raised to a level well above mean sea level to assure flood safety. The resulting ‘conventional terminal’ requires large volumes of fill material often dredged from the sea, which is costly. The terminal yard of a ‘polder terminal’ lies below the outside water level and is ...

The response of the Antarctic ice sheet (AIS) to changing climate forcings is an important driver of sea-level changes. Anthropogenic climate change may drive a sizeable AIS tipping point response with subsequent increases in coastal flooding risks. Many studies analyzing flood risks use simple models to project the future responses of AIS and its sea-level contributions. These analyses have pr...

Constraining the eruption rates of flood basalt lava flows remains a significant challenge despite decades work. One potential observable proxy for is lava-flow lobe thicknesses, topic that we tackle here quantitatively. In this study, provide first global compilation p?hoehoe lava-lobe thicknesses from various continental provinces (? 3,800 measurements) to compare characteristic within and be...

flood is considered as a major threat among natural disasters in the world. this case becomes more important and has a higher risk in urban areas due to the existence of important uses. therefore, to reduce damages resulted from flood, this phenomenon must be managed and planned using structural and non-structural approaches. considering the development in iran has been carried out in high risk...

(IPCC) (1) highlights the improved accuracy of measurements of current sea-level rise, as well as greater certainty in the projected impacts of global warming on non-polar glaciers and thermal expansion of the oceans. These advances heighten confidence in projections of the most predictable components of sea-level rise, but the IPCC's projections specifically exclude the contribution that could...

A new agricultural flood losses prediction method using digital elevation data combined with agricultural economic data is presented. The method is based on dynamically simulating the procedure of flood out. An example in Huangdunhu flood detention area, Jiangshu province of China has been given to describe how to use it to predict the incoming agricultural losses. Compared with prior methods, ...
