Where does the water come from; is this an artesian well? This is fascinating, very different from the acequia system used for field irrigation in my country.
In the case of this cylindrical diversion system, during the irrigation season, water is discharged into the river from a dam that stores water for agricultural use, and water is taken at the headworks and channeled through an irrigation canal. I think the acequia system is almost the same irrigation method up to the ditch (irrigation canal). Cylindrical diversion system are a uniquely Japanese method of distributing water fairly.
@@junchan_dam It is also quite beautiful. ☺Yes, acequias can get water from a head works or a diversion dam (more common). Thay are cruder, mostly just mud and clay canals above ground level (with levees) and drainage ditches dug down into trenches. They distribute through simple sluices, but inequitably so.
Cylindrical diversion devices began to be built around the beginning of the 20th century. This was due to the constant disputes over securing water for agriculture in various parts of Japan and the need for facilities that would allow for fair water diversion. Acequia has existed since a much older time, so the concept of water diversion may have been different.
見学者にやさしい素敵な場所ですね。いつか行けるかな。
コメントを頂き、有難うございます。
六月さんは青森県の川内ダムに行かれる程の行動力があるので行く気になれば行けるのでは（笑）
近隣には甲賀市・日野町ダム群もあるので多くの投稿ネタを一気にゲット出来ますよ。
動画ありがとうございます。去年行きました！
親水池からの分水が良くわからなかったので、丁寧に動画を撮ってくださり助かります。
見学しやすくて楽しい場所ですね。
コメントを頂き、有難うございます。
念の為、非灌漑期の今月に確認しに行ったかいがありました。
ゆっくり農業土木さんは灌漑排水学を専門に学んだ元大学院生さんでしたか。
勘違いや間違いを指摘されそうで怖いですね😅
まあ、あくまで個人の趣味なので大目に見て下さい。
@@junchan_dam 学んだとはいえ、実際に現場を巡った回数はJunchanさんに遠く及びません…。
素晴らしいご趣味だと思います、これからも動画楽しみにしています！
また、チャンネル登録していただきありがとうございます！
What is it? Thank you for you Video 🙂
Thank you for your comment.
This is an equitable distribution facility for agricultural water.
