Wetlands and Water Sources

These flashcards cover key concepts related to wetland hydrology and the various sources of water that influence wetland health and stability.

What are the main sources of water for wetlands?

Precipitation, groundwater, snowmelt runoff, and surface runoff.

What is the role of tides in wetland hydrology?

Tides provide a dependable water source and influence the water levels in wetland areas.

What is a vernal pond?

A type of isolated wetland with the least dependable water source, relying on direct precipitation.

What type of water source is associated with springs and seeps?

Groundwater, which is very reliable.

What are spring tides?

Periods of higher high tides and lower low tides due to the gravitational pull of the moon and sun.

Precipitation, runoff, groundwater, and snowmelt.

What is the difference between weather and climate?

Weather refers to short-term local events, while climate refers to long-term regional or global patterns.

What is thermal expansion and how does it relate to sea-level rise?

Thermal expansion is the increase in water volume due to warming, contributing to sea-level rise.

What is the significance of the Alligator River and Great Dismal Swamp hydrographs?

They illustrate differences in water table depth and wetland hydrology based on conditions before and after drainage.

What is the primary concern regarding climate change and snowmelt in Colorado?

Climate change may affect the dependability of snowmelt as a water source for wetlands.
