Hurricane Harvey update

The Greater Houston Metro just got pounded by one of the largest storms (in terms of rainfall) on record: Hurricane Harvey. There was widespread flooding across all parts of the metro, but my home and Rice university were largely spared. The skies are clear today, after ~5 days of nearly continuous rainfall. However, the cleanup effort for this disaster will last years and cost billions of dollars. Nonetheless, I am certain that Houston will come back stronger and better than ever. This ordeal has made me even more proud to be a Houstonian.

At my house, we had a small leak in an interior bathroom, but because we received so much rain over the duration of the event, the roof became saturated and the sheetrock partially collapsed. No one was hurt, thankfully, and repairs are already underway.

I am currently working on an NSF RAPID grant, which I compiled the following figure for. This figure shows total rainfall during the Harvey event with the City of Houston (CoH) labeled. The precipitation data were collected from the National Weather Service and then summed to produce the total rainfall numbers for the below plot. I am proposing some work on the Brazos River (BR) so this feature is also labeled.

Outreach module — Flooding risk in low-lying landscapes

I have put together an outreach module that describes some of the risks of flooding in low-lying landscapes. The module runs in Matlab, either within a licensed environment, or with the Matlab Runtime Environment (which is available to anyone).

Accompanying the GUI is a worksheet that steps through all the aspects of the GUI and attempts to demonstrate the principles of flooding in deltas without detailing the math or physics behind the model. My hope is that it will be helpful to High School educators in their course work.

So far, I have only written a worksheet targeted at 9-12th graders, but plan to write two more (one for younger students, and one for more advanced undergraduate/graduate students) worksheets in the near future.

Below is a demonstration of the GUI. The full information for the module (including the source code) is on my GitHub here. The project website is here.
