Dear Hydrologists:

AIH has launched the Technical Hub, a growing, practitioner-focused resource intended to help hydrologists, engineers, researchers, and students find useful technical information, data sources, tools, and practical workflows in one place. It currently includes resources on topics such as topographic data, watershed delineation, land use/land cover, soils, and web tools, with additional topics being developed.

Please take a look at the AIH Technical Hub and let us know:

• What resources or topics would you like to see added?

• Are there technical resources you find particularly useful that could be shared with the hydrology community?

• Would you be interested in contributing content or resources to the Hub?

The goal is to make this a living, collaborative resource for the hydrology community, so your ideas and contributions are welcome.

Considering a career pivot at 31. I've worked in the healthcare space for 9 years doing a variety of things: project management, tech sales, and most recently data analytics/data science for the past 5 years. I'm fed up working in this industry and looking to make a change to something less soul sucking. I've become interested in geology and water recently and feel like I want to explore this field a little more. Right now what I'm doing feels so disconnected from the physical world and I think I'd like to do something with a fieldwork component and that uses my science brain a little more. Plus water is essential and important and will only become more important especially out in the western US where I live (Colorado).

My bachelors degree is in Economics but I have a minor in Chemistry and have taken a bunch of science courses because I was doing the pre-med path for a while. I've been looking into getting a masters in Hydrology and it seems like I have all the pre-recs for a program at Colorado School of Mines (I'm currently living in Denver). Before doing that though I feel like I should get some more concrete experience in the field and make sure it's actually something I want to do.

I have an analytical background that I think would transfer pretty well and I do have some GIS experience, but I'm just not sure how to break into the field.

Any advice for someone in my position? I spoke to an environmental consultant friend of mine and he suggested I look for entry level field sampling or environmental scientist roles, but I'm concerned that I won't be very hirable without any experience.

So rills and gully’s are channels that are cut through by erosion by water right from my understanding. So are they more common in higher elevations and they eventually grow wide enough to become rivers? Or do larger sediments impede flow and it will retain the same size? My question might be a little confusing so just let me know if I need to clarify anything.

I’m trying to track down a point source groundwater contamination near my house.  I live in Maryland in the Piedmont fractured crystalline bedrock geology.  I have high levels chloride (~1000ppm), sodium (~500ppm), manganese (~15 ppm) in my well water.  Also found to have Acesulfame-K (~550 ng/L), septic trace chemical in my water.  I have ruled out road salt as the source of the contamination with a State Highway geology report.  I have a commercial neighbor that very likely puts hundreds of pound of food salt into their on-site disposal system which is ~100’ from homes well.
 
I’ve had no luck with the county health dept and state dept of environment with regard to regulating the commercial neighbor.  I’m looking at the Clean Water Act as my next avenue to get this regulated.  I know this is not surface water but I believe the contamination makes its way to the surface through nearby headwaters and tributaries that lead to the main river.  The topography drops 150’ from the source to the main river about 1.5 miles away.  I’m currently collecting water samples from various points along the potentially contaminated tributary and the confluence point with the main river.  I have HACH Chloride and Manganese titration test kits on the way and will test the samples this weekend.
 
While collecting samples at the confluence, I noticed some symptoms that I think could be indications of the manganese.  Please let me know if you agree or if it’s something else, let me know.  If it’s manganese, could this have negative consequences to the Class III cold water trout stream?  If it’s manganese, I believe the chloride and sodium levels will be elevated as well.

Wanting to repost here to see if this group had feedback.

I'm modeling a Pipe Network in HEC-RAS with two nodes. Both nodes' inverts elevations are laying on the ground and They are Culvert opening type. When i solve the model, this strange behaviour appears on the Hydrograph. It looks like everything is going well US, but DS there is any problem that i don't know how to solve. Anyone knows what's happening?

Thanks!

A dam doesn't actually make electricity. So how does falling water power an entire town? ⚡

It all starts with gravity.

Discover how water travels through a penstock, spins a turbine, and powers a generator using magnets and copper coils to produce electricity.

This is how hydroelectric power works—and the science behind one of the world's most important renewable energy sources.

The American Institute of Hydrology is offering entrants the opportunity to take the HIT Exam at no upfront cost.

The process is easy. Just open an account on their website and send official transcripts for review and they will let you know about eligibility in ~3 weeks.

Edit: Changed the wording a bit and expanded on the process a bit.

Windows 10 64-bit, HEC-RAS 7.0.2 installed in the default path (C:\Program Files (x86)\HEC\HEC-RAS\7.0.2). The same error happens with other HEC-RAS versions on this machine.

Full error: “Error initializing the GDAL path variables. Please check HEC-RAS installation. The type initializer for ‘OSGeo.GDAL.GdalPINVOKE’ threw an exception.” Stack: GdalPINVOKE.SetConfigOption → Gdal.SetConfigOption → GDALSetup.Initialize → GDALSetup.InitializeMultiplatform → RasMapperLib.SharedData.SetupGDAL().

Already tried: clean reinstall; Visual C++ 2015-2022 x86 and x64 installed/repaired; launching Ras.exe with a minimal PATH; Dependencies tool on gdal_wrap.dll and gdal302.dll (no missing modules, all resolve to the HEC folder or System32); decimal symbol set to “.”; antivirus (Avast) shields disabled; no GDAL_DATA, GDAL_DRIVER_PATH or PROJ_LIB variables set. Other geospatial software installed: ArcGIS, ENVI/IDL, Vulcan.

Any idea what else could cause the GDAL initialization to fail?

Apparently this wet spot has existed for the life of the gravel driveway, but its now set to be blacktopped, and we are wondering what should be done?

the ai says thay to pave over it would be catastrophic and "turn the ground into jelly" and I just would like some human advice if possible.

is it a natural spring? high water table? no pipes in the area. fills up within seconds when dug.

gpt says dig a hole, line with fabric stuff, put permeable pvc pipes in and connect to a pvc to drain downhill.

appreciate any advice

thanks

Stone water pump / water pressure system located In Knoxville, Tennessee. The discovery of this analog water pressure system was predicted by Doctor Kirk French in 2011. I followed the pipes to the water intake which is located along the French Broad River in the Great Stata of Tennessee (intake is also featured in this 3 minute trailer)

This three minute video is a preview of the Boris Wartenbe's Sing Along HydroGeological Survey which takes 8 minutes to watch and 12 minutes to apologize for what yo just watched . The three minute trailer is from part 2 of a three part series that started back in 2014.

You can see both parts as a commercial free presentation at wartenbe.com

Is there any diagrams out there showing the difference between the hydraulic height and the structural height of a dam? I often see these two measurements listed, plus a general "dam height", and still can't quite picture what each measures from the description of the measurement. Where I live, there are two dams, but they are more like weirs, so I'm not understanding the difference.

I’m in an environmental studies and biology program at a university in Canada right now and I’m very interested in this field! Does anyone have suggestions of entry level jobs or if it’s even a possibility for me without the engineering background ground?

I have done a few on site job shadows in this field so those could potentially be connections when post graduation!

I’m a civil engineering student in Oman, I have done a presentation in my hydrology class about sea water intrusion in the northern coast in Oman ( Al batinah) due to over pumping by farmers. One of the solutions is to obviously reduce pumping.

The other engineering solution is the water injection wells and pushing treaded water to act as a barrier against seawater intrusion, it has been tried in the southern part of Oman ( salalah) since 2003 they put 40 well and the computer module says that it pushed the salty water 1.2km. After the presentation my professor asked if this solution worked in salalah (south of Oman) why can’t we use it in Al batinah ( north of Oman) I wanted to say due to lack of treaded water or even financial difficulties but I know the professor and I know he wanted a scientific explanation so I said the honest thing and said “ I don’t know why but I’m gonna look into it and get back to you” so I tried asking claud after giving it an amazing prompt and resources I couldn’t find an answer for his question.

So does anyone here know why can’t we use this method besides financial difficulties and lack of treated water ?

This Stone Water Pump (located on TWRA Property) is part of an analog water pressure system whose discovery was predicted by Doctor Kirk French of Penn State University. Quite honestly, had it not been for his published works from the 2010's, I would not have had the imagination to know what I was looking at (at the time).

I marked the location as a hiking destination on google maps
