Hey @elonmusk and @realDonaldTrump you are destroying Americans’ lives with #DOGE. For example, I made low flow estimates for communities and families to ensure they were discharging wastewater or withdrawing water in a manner that preserves that resource for future Americans.

So many decentralized rain gardens and bioretention cells! Many of them linear and in-series, which is an effective way to lay them out. Wonderful examples of green stormwater infrastructure @inDowntownPDX @sustainablepdx @PSUArchitecture

Mass squishing: an ecological trap whereby a road and the associated vehicles impede amphibian migrating from wetland to upland habitat. These massive casualties are typically flattened at night during rainfall. Here is an example of a recent one on Rose Lane in Raleigh, NC.

Happy Friday #BAEPack!🐺 It's always a good week when we have successful defenses in Weaver Labs. This week Caleb Mitchell and Mohammad Nooshzadi had successful defenses!

On Tuesday I successfully defended my PhD dissertation titled Resilience of Stormwater Control Measures to Floods, Bioterrorism, and Industrial Runoff. It was a fun and rewarding experience. Thanks to @Storm_Doc for giving me this and many other opportunities to chase the storms!

Thank you @NaomiWithNature for posting this pic! As all y’all’s advisor, I am blessed to count so many amazing grad students (& supporting folks) as part of the Stormwater Team. Here’s 2 more pix to additionally capture the joy of celebrating the successes of @CalculatorCaleb

Everyday I’m am so so grateful to be a part of such a great team with these BRILLIANT people. Congrats Dr @CalculatorCaleb on making it to the first of many finish lines. I hope my defense is a fraction as good as yours!

This week I started as a Hydrologist with the @USGS_SAWSC! Joyful for this next chapter! I’ll start by researching hydrologic extremes: (1) low flows and (2) flood flows Stay tuned for my @NCState_BAE PhD defense: Resilience of SCMs to floods, bioterrorism & industrial runoff

Today, NC State BAE Extension hosted a joint workshop with the @EPA and Ohio State University. The "Evaluating Stormwater Control Measures' Mitigation of Biological Terrorism" workshop provided information for a variety of different groups. @Storm_Doc @NCSUStormwater

Happy World Wetlands Day! I challenge you to tell at least one person (who does not already know) how important they are to protect and rebuild. Then challenge them to do the same!

It’s been so long since I’ve Tweeted that they changed the name to X. It’s been so long since they came up with the water quality design storm that you need to multiply it by X.

The wetland vegetation has really taken off since planting last August. @NCDEQ 319 grant helped this sediment basin be retrofit to a wetland.

Harvesting my backyard wetland plants led to some cool discoveries: 1) roots grow bigger in water than in a soil-gravel, and 2) preferencial flow paths occur beneath the roots within the gravel where anaerobic conditions prevail.

Why do I always get stuck watering permeable pavers… Because I’m always testing out the infiltration of the pavement before and after maintenance. This test plot is only 2.5 months old, but lack of erosion control allowed the disturbed soil to clog it. More tests tomorrow!

I am looking for another MS student to work on a WRRI project that will enhance constructed wetland treatment using biochar, aeration, and duckweed.  I would be open to either an August 2023 or January 2024 start. Let me know if you or someone you know are interested!

Which would you rather take back to the lab for colony counts: 1) A 1L Nalgene bottle full of sample on ice in a cooler, or 2) A 100 mm diameter filter? This sampling method study will help us decide how different the results are. In the meantime, just go with the flow.

This storm water wetland in Lenior has been doing a great job in collecting sediment over the years, but it's time for a little maintenance. Making some room for more sediment and improving flow paths @Storm_Doc

Cleaning out the accumulated sediment from the Lenoir Stormwater Wetland. This wetland is functining as designed by @NCSUStormwater and improving water quality. @CityofLenoir is working Hoffman Paving & Grading Co to do the work. @CalculatorCaleb is onsite to manage the effort.

Been a busy week! 1) Clean out a stormwater wetland in @CityofLenoir, 2) surveyed a dry detention basin with @NaomiPitts11, 3) ran spore sampling experiments in the rain with @EPAresearch, and 4) visited a @caryncgov HOA bioretention cell that wants to be retrofit to wetland.
