Emriver Research Instruments

Steve has spent thousands of hours of R&D on our Emriver research instruments, including the sediment feeder, dye injector, groundwater system, and magnetic flow meter. He says "It's nice when you build and wire, and load the code, and thousands of hours of R&D come alive, and the elegant machine does its amazing thing."

Here he is with a media feeder bound for Saint Louis University.



To learn more about our research instruments, watch this video, and give us a call or email if you have questions or would like a quote. These instruments, for the Em3 and Em4 models, are modular and can be added to a model at any time.


Our First Shipments to Singapore and India

We now have over 350 Emriver models in 14 countries! Singapore and India are our latest additions.

An Em3 bound for United World College in Singapore.

Little River's People

We haven't been blogging much lately - because our hardworking and dedicated team is so busy keeping up with orders. Thought we should brag about them a little bit...


Jim King is our new Director of Production. He jumped right in building models and streamlining our production methods.
Erin Cotter has been with us for almost three years and does an amazing job making parts, managing inventory, building orders, and working with clients.
Parker Savka is celebrating his one-year anniversary at LRRD this month. He builds our tilt bases, writes complex code for electronics, and makes many components for our models.
Mason Parrone' joined us this spring and is doing a fantastic job of building our electronics and making components for our models.
Akiyo Matsumoto is our wonderful representative in Japan. She is traveling around the country attending conferences and meeting with schools, nonprofits, and agencies. 

Steve Grimmer joined us last fall as our organization guru to get the new shop in tip-top shape. And as a bonus he can also build flumes:)

Steve Gough, our owner, does...everything. Seriously, managing his business; building instruments and components; handling scientific questions; and imagining, researching, and designing new components and instruments.
Beth Fisher, now in my fourth year at LRRD, managing business operations. Yes, that's Erin in the background of this photo making us laugh.

Emriver Em4 at Fort Lewis College

We're thrilled that Fort Lewis College's amazing new science education effort makes use of our Emriver Em4 in the Geoscience Department! Discussion of the Em4 and its application starts at 1:20.

More sediment slugs, waves with our new CC media.

Today we did another three-hour with our new, finer, color-coded media.

The video and lighting are rough, but focus on the patterns; I see waves yet again, and some interacting with bank failures.  But also the bank failures might be caused by the passage of the slugs!

This finer media is more cohesive, and for that, and other reasons, displays very different behavior from our courser color coded media.

River sediment "slugs" and waves visualized, for the first time?

Honestly, I'm way behind on the literature, but I know that we've all pictured sediment "slugs" and such from our field observations, at least since the late 1980's.  Maybe it's been described, but I doubt visualized before now.

So here's a placeholder. 

I've seen these pattern in our models for years.  We've recently developed a finer color-coded media that shows them more strongly.  Here's a short, rough, demonstration.

We're able to build the models, but have no funding now for research using them; I hope you'll do this!

One Year Anniversary at LRRD's New Location

November 17, 2016 was the 1-year anniversary of our move to our new location at
550 N. University Ave. in Carbondale. The new space has been perfect for us!

Beth's first day in the office.

Moving the shop. Couldn't drive a forklift around the old building!

Lots of storage space.
