![]() ![]() Hurricane Maria made landfall as a strong Category 4 storm in southeast Puerto Rico on September 20th, 2018. In conclusion, this modeling framework can be also applied at other coastal watersheds to evaluate the projected climate change impacts on the compound flooding induced by extreme climate events. The projected SLR will have little effect on the maximum inundation depth and extent if storm surge changes are not taken into account meanwhile, it will influence the inundation duration at downstream locations. ![]() Furthermore, considerable increases in maximum inundation depth and duration in regions along the middle and downstream of Clear Creek (and also those around Clear Lake) are expected. Meanwhile, the increases in maximum inundation extent would be 11.0 % (2050s) and 19.5 % (2090s). This means a 16.1 % increase in Harvey rainfall over the watershed per degree Celsius increase in Mean Surface Temperature over the Gulf of Mexico region (18°~31° N, 77°~98° W). The results show that the projected maximum rainfall totals over the watershed would be exacerbated by 17.7 % and 49.7 % in the 2050s and 2090s (respectively) under Representative Concentration Pathway 8.5 (RCP 8.5). The framework was applied to Hurricane Harvey (2017) at the Clear Creek watershed (a more » coastal watershed in the southern Houston) as a case study. To this goal, a modeling framework is designed based on the Distributed Hydrology Soil Vegetation Model (DHSVM), the Two-Dimensional fvand the Regional Community Earth System Model (R-CESM). This study investigates the future warmer climate impacts on hurricane-induced extreme rainfall, and-more importantly-the subsequent compound flooding at the watershed scale (from an event-based analysis perspective). Thus, how the floods induced by intense hurricanes respond to these potential changes is of great concern. The warming climate is likely to increase hurricane-associated extreme rainfall and lead to sea-level rise (SLR). A pair of high risk scenarios of the effect of a future warmer climate and a hypothetical storm similar to Harvey is also = , The variety of scientific opinions as to the human effect on precipitation and their effect on the flood are presented as detailed in the table below. The public is then invited to compare the "flood that might have been" had there not been a human interference in the climate system to the simulated actual flood in these neighborhoods. A detailed validation of the baseline simulated "flood that was" for every neighborhood is outside the scope of this article but individuals can compare the simulation to their own experiences. The public is encouraged to download this open access data and investigate their own neighborhoods of interest using free or commercial software. Geospatial data to visualize the attributable flooding in the greater Houston during Hurricane Harvey as simulated by the Fathom hydraulical model in a geotiff file format is provided at.

This article originally appeared on CNET. Catastrophic flooding in Texas from Harvey 74 photos And Google has done everything from making satellite photos publicly available to creating an online person-finder. ![]() Apple has used iTunes to collect donations for disasters. Facebook's "Safety Check" feature is so popular that it's become a permanent placement on its site. Of course, this isn't the first time tech has been used to help in a catastrophe. Currently, it's counting 991 roads inundated in Houston as a result of Hurricane Harvey. It relies on the community to update the map, and so far has received more than 1,500 reports. The project, by consultants at the environmental firm Marine Weather and Climate and the tech company Tailwind Labs, is an interactive map of flooding in Houston as well as other cities like Galveston, Baton Rouge and New Orleans. But now, a project called U-Flood promises to show us exactly how bad the flooding from Hurricane Harvey really is. Online maps have already changed the way we move around in the world. ![]()
