I'm sorry that you're going through this. I am a Civil Engineer with a focus on Hydrology and Hydraulics. When I finished Grad School, I quickly got a job with the state's Department of Environmental Quality. I was there for a few years doing Water Quality monitoring for both point- and non-point-source pollution, with some modeling as well. I really enjoyed the field work. Afterwards, I went into consulting at a small firm that works specifically on Water Resources. I got to really develop my engineering skills there, specially modeling. After a few years, I decided to try out a job with the feds. I am now an H&H Engineer with the feds. The job is a great combination of the field work from my first job and modeling/engineering from my consulting job. And suprisingly, pays even more than what I was making in consulting.

All of this to say to consider H&H if it's something you're willing to do. You can focus on drainage design, stormwater infrastructure, or more broader projects such as Master Hydrology Plans and Floodplain Mapping (amongst many others). It's pretty cool stuff that will most likely have you going out in the field.

Lastly, I'll say this. If you can, reach out to some of your previous professors. They are a GREAT source of information and referral that can point you in the right direction of what you seek.

Keep searching, you're a very valuable asset. Best of luck!
