design principle flow, filter, and purify water A flow is made up of elements that aggregate into a larger mass. Flows can be managed by planning how to direct the flow. The main variables in a drainage network that control a water system are gradient, discharge, and sediment.
Related design principles:
Collected water, especially water with a high velocity, can produce strong forces against objects, causing displacement and erosion. It is costly to try to control the flow of water because of forces such as gravity and fluid dynamics. Water wants to move.

• Filtering of a flow can occur through turbidity and velocity. Physical filters can pull out and consume unwanted materials.

TOC
Water flows serve more than one purpose. Healthy flows are not static. Water moves materials with its flow. Water wants to branch and channelize. Plants and living organisms help purify water. Sediment provides resources and a filter.
