deranged drainage system
a system without any obvious or coherent pattern as a result of much geological disturbance, as in areas cleared of soil cover by ice ages. The drainage patterns are still being determined and the glaciers left much water that accumulates in low points as lakes. See also annular, dendritic, parallel, rectangular and trellis drainage systems
