Hangar destroyed. Four aircraft inside the hanger and four aircraft outside of the hanger sustained damage. This effect occurs when high winds strike tall buildings, creating friction. "The researchers experimented with different computer models to simulate Hurricane Harvey's rainfall in Houston, first looking at total rainfall with the city's current urban profile, then at rainfall for the same geographic area but with open fields and crops in place of streets and skyscrapers.

Some central areas of Houston recorded 7.80 inches (198.12 mm), according to figures from Harris County Flood Control District. They found that the non-urban areas received significantly less rainfall, and that rainfall patterns were significantly different than in the urban areas.The reason was that "surface roughness" due to the presence of human-made structures create a "drag effect" on hurricanes. In the case of Hurricane Harvey, winds shifted warm surface air farther up into the atmosphere, thereby creating an optimal situation for cloud formation and precipitation. After the tremendously destructive floods of 1929 and 1935, however, citizens clamored for solutions. "Using statistical models, the researchers also looked at year-over-year changes in flood peaks and compared them to rainfall amounts and population growth, a proxy for urbanization. This database (as of 6/24/20) contains severe weather reports from 1/1/50 thru 3/31/20.Search the NCEI Storm Event database to find various types … The 10 storms that caused the most damage throughout the Houston area in 2018 Explore Houston's flood-prone areas. John Bacon. As the city's miles of impervious sidewalks and streets increased, heavy rainfall could not be absorbed into the ground.
Flash flooding in Houston sparks memories of Harvey Residents watched cautiously as parts of the city received up to 8 inches of rain. Photo: Godofredo A. Vasquez, Houston Chronicle This increase in urbanization, combined with the region's flat clay terrain, represents a very problematic mix, even with flood-mitigation measures in place. 1907 - Major storm floods much of Houston.

"The researchers found that as Houston's urban center grew upward and outward, flood risk changed, including a greater risk of higher flood peaks and more serious and dangerous flooding overall. "When Hurricane Harvey blew into Houston, it literally got snagged on the city's tall skyscrapers and towers," said Gabriele Villarini, associate professor of civil and environmental engineering and director of IIHR. "Our focus on the role of urbanization was aimed at providing a fuller perspective of human activities on Harvey's rainfall and flooding," said co-author Gabriel Vecchi, a Princeton professor of geosciences and the Princeton Environmental Institute (PEI). Weak regulations have failed to properly estimate the potential hazards of flooding. Some central areas of Houston recorded 7.80 inches (198.12 mm), according to figures from Harris County Flood Control District. Have any problems using the site? Chat with us in Facebook Messenger.
