Which outcome occurred when ancient Mesopotamian stepped canals exceeded their intended volumetric capacity?

💡 Explanation

Silt deposition blocked flow because capacity exceedance induced laminar flow within canal segments, thereby reducing sediment transport rather than turbulent suspension; therefore sediment accumulated because reduced velocity, rather than scouring away or downstream fertilization.
