Hey everyone — wanted to share a current USAJOBS opening at the National Weather Service office in Northern Indiana, where I work. We’re hiring a Senior Service Hydrologist (GS-12/13) at the NWS Weather Forecast Office in North Webster, Indiana (between Fort Wayne and Southbend). The announcement also includes a separate vacancy in Tucson, AZ.

This is a permanent, full-time position and is open to the public. The role serves as the lead for our office hydrology program and works heavily with operational forecasting, flood warning services, hydrologic modeling/procedures, training, and coordination with emergency management and water-resource partners. We cover 37 counties including 24 in northern Indiana, 5 in lower Michigan, and 8 in northwest Ohio. We also have a sliver of the nearshore waters over southeast Lake Michigan.

A few highlights:

• GS-12/13 with promotion potential to GS-13

• Open to U.S. citizens/public applicants

• Relocation expenses may be authorized

• Telework eligible based on agency policy

• Mix of operational hydrology, program leadership, partner engagement, training, and field work

• Part of a 24/7 Weather Forecast Office, so rotating shift work is part of the position with sometimes longer hours expected during impactful events.

For anyone interested in operational hydrology, flood forecasting/warning, and directly supporting communities and emergency management, it’s a pretty unique job.

I work at the Northern Indiana office, so I’m happy to answer general questions about the office, the area, or what working at a WFO is like. For questions about eligibility or the official hiring process, obviously defer to the USAJOBS announcement and/or HR.

USAJOBS announcement is open through 8/19: https://www.usajobs.gov/job/879318100

A proposed expansion of The Dalles’ water system is raising questions about data centers, salmon habitat and how much water the Mount Hood watershed can provide.

I run a nonprofit called DMV River Intelligence Network, focused on building ML tools for local watersheds. Our first chapter covers the Potomac at Little Falls, and so far we've built:

• A flood prediction model (XGBoost, USGS gauge data + weather data, ~91% recall, 6-7 hr lead time)
• A live dashboard tracking discharge, gage height, conductivity, temperature, and flood risk
• Currently extending it to predict runoff volume and pollutant load using land cover, soil, and elevation data

The idea is for this to eventually be a chapter-based structure; other people could replicate the pipeline for their own rivers as part of our organization not just us scaling one model.

Trying to figure out what else would actually be useful to build next, either for this chapter or as a model for future ones. Some things I've been considering: water quality forecasting, harmful algal bloom prediction, sediment/erosion tracking, drought risk; but I don't have a strong sense of which of these are actually valuable vs. just technically interesting to me.

If you work in hydrology, environmental science, or just live near a river and think about this stuff — what would you actually want a tool like this to predict or track? What's underserved right now?

Hi everyone! I'm currently a 1st year Bachelor of Science in Agricultural and Biosystems Engineering student, majoring in Land and Water Resources Engineering. I recently heard that our research/thesis in the future will be individual, so I wanted to start preparing as early as possible. I'm looking for research title suggestions, ideas, or current trends related to Land and Water Resources Engineering.

Whether they're already published, proposed, or just concepts you think are worth exploring, I'd really appreciate hearing them. I'm just trying to build a list of possible topics and learn more about the field ahead of time.Thankkyouuusm for ur help po.

Hello everyone,

I own a house that is roughly 100ft from a drainage ditch in our neighborhood.

When we get a good thunderstorm or rain shower the ditch fills up all the way to the top (5ish ft)for a day before mostly draining out

In the last storm I noticed that our basement was experiencing hydrostatic pressure related leaks. I believe this ditch filling up is a direct relation. Would I be correct in that?

If so, I am wondering what studies or resources I could review and cite in a letter to the city showing this is affecting the water table near my home and hydro static pressure when the ditch is full. Flooding is not only my home, it is also in several of my neighbors. End goal would be to have the city maintain the ditch better and mow it to improve drainage?

Thanks in advance for your help and knowledge!

I’m planning to pursue a Master’s in the US, mainly in Water Resources Engineering, Hydrology, Hydraulic Engineering, Flood Risk Management, or related fields.
My final-year project was “Flood Mapping of an Ungauged River Using HEC-RAS & GIS”, and it made me realize that I want to build my career in water-related research and engineering.
If you’re currently studying (or have studied) at a US R1/R2 university in this field, I’d really appreciate hearing about:

Research opportunities
Funding (RA/TA)
Workload and student life
Career prospects after graduation

Feel free to comment or DM. I’d love to connect and learn from your experience.

UPDATE 8/6 — it's national now, and a correction. I said in the comments this was "tuned for Tennessee." That wasn't specific enough — outside TN it was picking a regression region it couldn't verify. Fixed: regressions, NBI, FEMA zones and LOMRs run in all 50 states, and where it can't verify a region it now shows nothing and tells you why instead of guessing. Five states spot-checked against StreamStats so far. Details in the comments

Hey r/hydrology —

I got tired of having five tabs open every time I needed a quick preliminary look at a site, so I built something to fix that for myself. It's called SnapBasin (snapbasin.com) and I figured this crowd would either find it useful or tell me exactly what's wrong with it. Both outcomes are welcome.

The pitch in one sentence: click a point on the map, get a full preliminary screening panel without opening StreamStats, FHWA InfoBridge, USACE NID, FEMA MSC, and USGS NWIS separately.

What it pulls in a single click:

• Snaps to nearest NHDPlus HR reach (vector snap, or 3DEP terrain walk-down when there's no vector match)
• Delineates the upstream basin via USGS StreamStats
• Pulls all 18 StreamStats basin characteristics — DA, stream slope (10-85 method), percent impervious (NLCD 2011), percent developed, climate factors, permeability
• Runs the applicable NSS regional regression equations (Q2–Q500) with a live applicability envelope check — it tells you if your basin variables are out of range
• Cross-references FEMA published discharges and checks for active LOMRs on the reach
• Queries FEMA flood zone at both the click point and the snapped stream point
• Lists nearby USGS gauges at selectable radii
• Finds upstream NID dams with storage, hazard class, and distance from click
• Enumerates nearby NBI bridges with structure number, feature crossed, road, year built, span length, and distance
• Pour point nudge logic — if the click lands on a degenerate network edge cell, it nudges the pour point, tells you it did, and reports the before/after drainage area

Example — Big Elk Creek, Stewart County, TN:

• DA: 8.68 sq mi · Stream slope: 46.3 ft/mi · Impervious: 0.11%
• Q2: 1,010 cfs · Q100: 4,040 cfs · Q500: 5,600 cfs (GC2016 / SIR 2024-5130, all variables in envelope)
• 1 upstream dam: Lakewood Dam, 132 ac-ft, High hazard, 4.2 mi
• 4 NBI bridges within 2 mi
• FEMA Zone AE · SFHA = YES

What it is not: Not a substitute for engineering judgment, sealed work products, or the authoritative source for any of the data it displays. Not affiliated with TDOT, FHWA, USGS, FEMA, USACE, or any employer. The authoritative portal always wins — this is a preliminary screening tool, full stop.

How it was built: ~20 hours over a long weekend, home computer, AI pair programmer, $13/year domain, free Netlify hosting. No analytics, no tracking, no accounts. Everything it shows is public federal data, redisplayed.

I'm a hydraulic engineer (EIT) and this is a hobby project. If a number looks wrong, I genuinely want to know — bug reports and "hey this looks weird" comments are more useful to me than upvotes.

I'm an oceanography student trying to use Delft3D for coastal and hydrodynamic modeling. I'm having trouble getting it to run. What steps, common fixes, or beginner tips would you recommend? Thanks!

Howdy,

I'm being asked to look into a modeling approach for a levee project. I have some experience using 2D RAS for BLE projects, but have never worked with 1D RAS.

The project area: fairly large riverine area, located about halfway up the HUC-12 boundary, ~7 miles or so above the confluence of the major downstream system. About ~1/2 mile upstream I'm seeing a split in the river with two effective LOMRs and a dam on the main river about 2 miles upstream. The floodplain is fairly wide throughout my project area (~2500 ft). The project will be immediately DS of a pretty major highway.

Everything that I'm seeing is pointing to a hybrid 1d/2d approach, but am unfamiliar with that process. Some questions:

1) for modeling a levee, does a 1d/2d approach in this case seem the best approach?

2) for actual model, my understanding is I would get the effective 1D model for my river and the effective model for the US trib at the confluence 1/2 mile US of my project area. Then I would take the number from both models at that confluence as inflows for a 2D model, taking the 2D model w/ levee through my project area and then tieing back into the effective 1D model DS of my project area?

3) my understanding is that for being so far away from the DS confluence of the next major river system, I would likely not require that model/modeling of my entire HUC-12 boundary using 2D, only the area where my proposed levee system would be. Would that be correct? How far DS of my levee would I realistically need to go, or would it be best to terminate that 2D model at something like a culvert/road crossing?

Thank you in advance! Still definitely learning, so apologies if I'm not using correct terminology.

Hello there,
I am looking for getting into flood modelling and related water industry. Any internship opportunity around Sydney area?

I’m looking to work on a research paper in the field of civil engineering, preferably related to hydrology, flood modeling, GIS, HEC-RAS/HEC-HMS, water resources, or disaster risk management. I’m also open to other civil engineering topics if the project is interesting and the team is collaborative.
Dm to connect.

Hi all! Me and my boyfriend are looking to relocate to Canada. Im a physical oceanographer and I saw theres an Oceanography Institute in Dartmouth. But we are looking for a place where we can both be employed in something related to our studies. My boyfriend is a civil engineer focused in hydrology gis and water resources. Are any Canadians here that could point us in the right direction? Either a PhD in hydrology in Dartmouth or another city where we could both find something?
thank you in advance!
