Watersheds • A watershed is a geographic area in which water (surface runoff, lakes and streams) drains to a common outlet. Because of the integrated nature of natural drainage systems (i.e., smaller tributaries joining to form larger streams), watersheds form a nested hierarchy of areas (i.e., smaller watersheds subdivide larger watersheds).

Watersheds • The watershed of any hydrographic feature (lake, stream or wetland) is the surface area that contributes overland flow (runoff) to the feature. In most landscapes, the surface watershed corresponds with the subsurface watershed which contributes interflow and groundwater discharge.

Watersheds • To appreciate the diverse valley forms of the Grand River and to explain why it winds across southcentral Michigan with several large meander bends, we need a quick review of the recent earth history of the area. Let’s pick up the story as the last ice age comes to a close, about 15,500 C 14 yrs ago.

Hydrologic Cycle Baseflow
• The baseflow of a river is the amount of groundwater discharged from an aquifer into the watercourse. − This discharge occurs yearround, but fluctuates seasonally depending on the level of the water in the aquifer.
− The baseflow of a river is supplemented by direct runoff during and immediately after precipitation or snowmelt events.

Influence of Development • Produces greater volume of runoff
-increases the coefficient of runoff -decreases infiltration
(limiting groundwater recharge)
• Increases delivery rate of runoff increases the drainage density faster channel flow in ditches and storm sewers (compared to natural channels)

Influence of Development • Polluted runoff is now widely recognized by environmental scientists and regulators as the single largest threat to water quality in the United States (non point source pollution).
• Urban stormwater management is a critical component of watershed management.

Channel Pattern • Meandering • Length of straightchannel reaches rarely exceed 10 times channel width e.g., for a 40 ft.wide stream, straight reaches will usually be less than 400 ft. long.
• Thalweg
-line of maximum depth & velocity
-as the thalweg becomes sinuous, a PoolRiffle sequence develops
