In this project, they're concentrating on two applications — the way in which oil flows within its natural reservoir, and the
way flood waves spread across a landscape.
Today, simplified 2 - D flood models are the state of the art for predicting
flood wave propagation, or how floods spread across land.
Hensch said the biggest risk in Iceland itself was
from flood waves from any eruption under the glacier.
From the reports, it sounds as if a storm dumped the water in the upper portion of the basin at an extreme rate, creating the
large flood wave.
When the water sources that empty into a river rise simultaneously, they can trigger one or more
successive flood waves.
«Advances in numerical algorithms, automatic grid generation, and increased supercomputer power will eventually make the simulations of
flood waves over large durations of time possible using Titan, and even more so with Summit,» Constantinescu said.
Simulation results also demonstrated that 2 - D models may underestimate the speed at which floods spread and overestimate the time at
which flood waves reach their highest point.
Pushing the boundaries of representation, many of Bisky's figurative paintings are suffused with densely packed body parts caught
in flood waves and wedged into one another.
Glacial
outburst flood waves and increasing slope collapse risk are a climate change related issue...
This causes
violent flood waves that can reach as high as 15 meters, destroying downstream settlements, damns, bridges, and other infrastructure.
«When my group and I won the contest, the first thing I felt was shock and then
a flooding wave of excitement.
A team at IFC, led by UI Professor George Constantinescu, is creating 3 - D non-hydrostatic flood models that can more accurately simulate
flood wave propagation and account for the interaction between the flood wave and large obstacles such as dams or floodplain walls.
When they compared the 2 - D results against those of the 3 - D simulations, they found that the 2 - D model underestimated how quickly
the flood wave moved across land and overestimated the time at which the maximum flood occurred.
Because 2 - D models make simplified assumptions about some aspects of the flow, they can't account for changes in the flow, such as when
the flood wave moves around large obstacles, changes rapidly in direction, or fully immerses bridge decks.
There is room for optimism —
this flood wave is very sharp and will be days long... rather than weeks.
