Bet vai mūsdienās upes pārvietojas?

    Pārvietojas gan. To sauc par krastu izskalošanu. To, kā upe maina savu izskatu, nosaka atšķirīgo iežu izskalojamība, ūdens daudzums, hidroloģiskai režīms, kritums, zemes garozas kustība un cilvēku darbība. Upe var iegrauzties gan dziļumā, gan uz sāniem. Ir upes, kuras gadiem nemaina savu gultni. Toties, piemēram, Gaujā vietumis ir novērota krastu erozija līdz 4 m gadā. To, kā pārvietojusies upe, liecina dažādās vecupes.

    Sīkāk par to var palasīties enciklopēdijas «Tava labākā grāmata par Latviju» 5. sējuma 253. lappusē.
