Abstract
The United States waterways Experiment Station at Vicksburg, Mississippi, recently conducted a series of tests which were intended to throw light upon the problem of the meandering tendencies of alluvial streams. [These tests are described in full in Tech. Memoranda Nos. 61‐1, 61‐2, and 61‐4 of the Experiment Station,] These tests were conducted in a flume 15 feet wide and 50 feet long (see Figs. 1 and 2) . The flume was filled with clean, medium‐size sand to a depth of about 1‐½ feet. In each test, a straight, parabolic‐shaped channel was molded through the sand, lengthwise of the flume, with one curve at the upstream end of this channel (see Fig. 3). A constant quantity of water was supplied to the head of the channel, and sand was added to the channel at a uniform rate. A constant over‐all slope was maintained by the control of the water‐surface elevation in a tailbay at the downstream end of the channel. With only these items of control, the channel was permitted to meander through the sand‐bed of the flume.
