Human Changes in Waterways

Humans can change natural waterways (creeks and rivers) in many different ways to suit their needs. For example, waterways can be deepened or widened to assist in boat navigation, or their banks strengthened to help reduce erosion and the impact of flooding. Sometimes even the direction of a waterway can be changed (eg by dredging). Some creeks can become concrete channels like part of Blacktown Creek below.
