Vist our new Emriver support newsgroup!
This page contains support documents and updated information on the use and maintenance of your Emriver model. We also welcome your questions via email or telephone.
We have made some minor improvements in the Emriver model since many of the photos on other pages of the website were taken. Use only this page as a reference for technical questions. And don't hesitate to email or call us!
These manuals give detailed technical information on use of the Emriver model for demonstrations, teaching, and experiments. Click here to download in PDF format.
We have made a minor change to the valve assembly, which allows it to be rotated 90 degrees clockwise so that the valves are located under the top of the gunwales. The top position is best for access to the valves. If you are doing a lot of measurements in the lower end of the box, however, it may help to move the valves out of the way. The changes include reversing the direction of the Y-manifold, which now angles to the right as you face the box from the reservoir end, and also a second hole in the box, farther to the right, which is used when the valve plate is rotated to the right.

Beginning in June, 2008, we redesigned the level rod and support so assembly is self-evident. Instructions for assembling the old leveling rod.
The modeling media tends to self grind during shipping, which produces some dust. There is no way around this. You may want to wash the media by running a few changes of water through the system the first time you use it.
After this, the water in your model should be very clear, allowing you to easily observe bedload transport and bed features in the model.
Use these files to print paper inserts for your head scale. There are two versions:
Scale in millimeters (a simple millimeter scale). This is a copy of the headscale insert that came with your Emriver model.
File that can be modified to produce a scale calibrated in ml/s
The AutoCad file must be modified based on the particular calibration data for your headscale - notch gage pair.
