The former Taiwan Provincial Government budgeted more then NT $ 200 billion for "flood prevention, drainage, and water and soil conservation," with the aim of "managing" Taiwan's rivers. Riverbed reinforcement was part of that program.
原來，前台灣省政府曾編列一筆二千多億的「防洪排水及水土保持」經費，用以整治全台灣的河川，屬於該計畫一部份的固床工程，就是為了防範河床下切與河岸衝蝕，就將河道截彎取直，在河床上、河岸邊全部鋪上水泥。
