上富田町の富田川はあまり蛇行せず活断層帯の低地を流れます。右岸にある下鮎川には、小規模ながら典型的な河岸段丘が見られます。この河岸段丘は3段あり、もっとも広く発達する標高約65ｍにある2段目の段丘面には、耕地として利用され「平」や「畑」の字をもつ地名が多いです。

The Tonda River in Kamitonda Town does not meander very much and flows through the lowlands of the active fault zone. The Shimoayukawa on the right bank has a small but typical river terrace. This river terrace has three steps, and on the second terrace surface, which is the most widely developed terrace at an altitude of about 65 m, there are many place names that are used as cultivated land and have the characters "hira" and "field".
