Vladimir Tislenko from Tomsk State University of Control Systems and Radio Electronics wrote to tell us about two Kalman rivers connected to the Irtysh river in Siberia. He included some photos (see below) and says

R.E. Kalman says

It has been conjectured that Magyars (Hungarians) were in South/Western Siberia some 1500-2000 years ago, and during that conjectural presence may have left the name "Kalman" (precise meaning unknown) there or picked it up from there.

Here are the photos Vladimir sent.
