2. Wetlands
Characteristic hydric soil and hydrophytic vegetation as signs of frequent surface saturation or inundation.
Many types of wetlands: (Dodds, 2002; Table 4.3)
Salt-marshes and (temperate, seawater influence)
Mangrove forests (tropical, seawater influence)
Tidal & non-tidal freshwater marshes
Deepwater (cypress) swamps
Northern (bogs & tundra) wetlands
Riparian forests/wetlands
Man-made (rice paddies & bioremediation)
Function as nutrient and sediment traps; slow runoff and facilitate recharge; most are highly productive.

3. Global Distribution Depressional Peatland bog Coastal Mangrove
(Matthews, 1993)

4. Geomorphic: Peatlands; Coastal; Riverine; Depressional.
Wetland ecosystem types are based on hydrologic regime, climate, geomorphology, nutrient input and vegetation. (Dodds, 2002; Table 4.5)
Geomorphic: Peatlands; Coastal; Riverine; Depressional.
Hydrologic Regime:
Permanence, predictability (e.g. tidal), seasonality
Primary water source:
Precipitation; low throughput (ombrotrophic)
Riverine; potentially high throughput (minerotrophic)
Groundwater
Climate determines the balance of precipitation and evapotranspiration. (E.g., much less precipitation is required for tundra wetlands than that for a tropical savanna wetland.)

5. Human Impacts on Groundwaters; Streams and Wetlands
Groundwater or surface pumping:
agriculture
industry
drinking waters.
Clearing riparian forests & wetlands
Draining and filling for “development”.
Damming and flooding
Diversion channels for water supply.

6. Levee

8. Arkansas River (?)

9. Vanishing Florida Wetlands

12. Wetland loss from 1780 to1990. 70% Riparian Forest lost in USA.
Worldwide estimates are >50%; half due to agriculture.
