Watch our new video of the Emflume1

Check out our new video on the revolutionary, turnkey, desktop Emflume1. We introduced the Emflume1 in 2013 and it is now in use around the world, helping students in engineering, geosciences, and fisheries learn fluid mechanics with hands-on experience in the lab.

Em2 Owner Receives Environmental Excellence Award

Vermont’s Ottauquechee Natural Resources Conservation District was a recipient of the 2015 Vermont Governor’s Award for Environmental Excellence for their River Road Show, a traveling educational display that uses the Emriver Em2 model to demonstrate how rivers and streambanks react to human impacts. The program has educated thousands of Vermonters on river science and flood resiliency. We blogged about the great work ONRCD was doing in 2013.

With 13 Emriver models in use throughout the state by multiple agencies, organizations, and schools, Vermont continues to be a leader in using the models to effect positive change in river management and education. Keep up the great work!

Em2 Installed in Japan Museum

Little River is proud to have an Em2 model at the Kanagawa Prefectural Museum of Natural History in Japan. A big thanks to Akiyo and Go Matsumoto who represented Little River during the dedication ceremony and demonstration in July.

Japan Geoscience Union meeting in full swing

We are happy to report our exhibit in Japan is being visited by multitudes of Japan Geoscience Union meeting attendees. All the excitement has us barely feeling the time change anymore. Despite Chiba, which is located in the Greater Tokyo Area, being 11 hours ahead of Southern Illinois, we are having a phenomenal time at JpGU.

On Monday we felt an earthquake that was centered just northeast of Tokyo. The U.S. Geological Survey measured it at a 5.3 magnitude. There were no immediate reports of damage or injuries.

If we had been filming the Em2 when the earthquake happened, we would have captured the significant bank failure we saw in the model.

A few visitors to our booth had seen us before at the American Geophysical Union meeting in San Francisco, and they were happy we brought two of our models, an Emriver Em2 and Emflume1, to Japan. Thanks to the packing skills of Steve, Jim and Keisha, they arrived safe and sound without a scratch.

Thursday is the final day of exhibition, and we hope you will stop by and see us in booth number 43 if you are at JpGU. If you are elsewhere, you can see the next best thing--more photos from JpGU on our Facebook Page.

Em2 and Emflume1 models to make debut in Japan at geoscience meeting

Editor's Note: Akiyo Matsumoto, who is a native of Japan, translated this post into Japanese.

Three of us from Little River Research & Design are heading to Japan in a few days to attend the Japan Geoscience Union meeting.

JPGU is a partner organization of the American Geophysical Union, and we have attended annual AGU meetings for several years.

We are excited to be taking two of our models to Japan. We will have an Em2 and Emflume1 near Tokyo at the Makuhari Messe International Conference Hall in booth number 43 from May 24 to 28.

Japan has a long history of river research, and many challenges with water-related geohazards, including flooding, landslides and tsunamis. Our Emriver models can further efforts to understand these hazards.

We are also excited to add two Japanese institutions to the list of our worldwide owners. Our Emflume1, Em2, Em3 and Em4 are facilitating river science education and research in Canada, Australia, nine countries in Europe, China, Taiwan, and 48 U.S. states. We are happy to add Japan to the list!

We look forward to meeting new people at JPGU and continuing to send our models across the world to contribute to worldwide science education and research.

Little River heads to Environmental Education Association conference

In an effort to share our interest in outreach environmental education with others, we are attending the Environmental Education Association of Illinois Annual Conference at the Touch of Nature Environmental Center in Makanda, Illinois.

The conference began today and runs through Saturday, April 11. Amanda and Jim will be there for Friday’s events, which include an exhibition of one of our Emriver Em2 geomodels facilitated by Amanda.

This year’s theme is Bridging Gaps Under Southern Skies, which emphasizes the connection between creating programs for people from all walks of life and understanding how to align programs with STEM and Next Generation Science Standards. Sessions include Environmental Education in Practice, Environmental Literacy, and Journey into Environmental Education.

Little River has always considered environmental outreach education one of the primary tenets of our models. From the U.S. to the UK and beyond, Emriver models have been used in demonstrations for all ages on how waterways are connected to the land and people.

By encouraging hands-on play and experimentation, people can observe different visible processes, such as infiltration, seepage, erosion, and deposition, while listening to an educator explain what is happening. Learners can then put their observations into words, involving them mentally and allowing multi-sensory learning to take place.

We're excited for tomorrow and the opportunity to teach fellow attendees and learning from them as well.

Powering Emriver Geomodels with batteries

Students experimenting with an Emriver Em2 geomodel.
There's nothing quite as cool as running an Emriver model next to an actual river! It's a fantastic way to teach fluvial geomorphology.

Our Em2 and Em3 models are designed for portability, and you can use them just about anywhere. For field sessions or spots without easy access to wall current (or "mains power" in the UK), you can use a 12-volt battery.

While we supply a battery power hook-up kit, we do not supply batteries. They are best bought locally. Here are a few tips on finding the right battery:

1. Make sure it's a "deep cycle" battery. Car and motorcycle batteries won't work. They are not designed to be deeply discharged, and they will be damaged if they are.

2. Make sure it's a sealed battery that can be tipped, even used upside down, without spilling acid. These batteries are designated "SLA" for "sealed lead-acid." Another designation to look for is "UB" for "universal battery." These are very commonly used for computer backup systems (they're inside that big black UPS box) and to power alarm systems during power outages.

3. Get a battery with at least 12 amp-hours of capacity; this will sometimes be abbreviated as "12ah."  The Em2/Em3 pump uses only about one Amp of power. A good 12 Amp-hour battery should power it for at least four hours. If you want to know more about this, there are many sources on the web, and here's a detailed one.

The photo below shows a good choice, a UB12120, or "universal battery" 12-volts, 12 Amp-hours. This battery will weigh only about seven pounds and be 6 x 3 x 3 inches in size. It's very compact and easy to manage. These can be bought locally and online.

Get a charger from whoever sells you the battery, and you're ready for the field! You don't need a large automotive-style charger. Here's a small one we like at LRRD.
