What am I trying to say from my work?
How does the forest manage drought?
Pines are fine
the water table varies more
WT controlled by ET And P
Less P means ET uses more groundwater
The forest manages drought by extracting more water from the saturated zone, which it easily accesses due to the shallow depth of the water table
How does the forest manage huge storms?
It manages storms through runoff, flooding and saturated soils
Pines are fine
The water table rises easily
after the water table and unsaturated zone increase to a certain point, the excess is managed through saturated excess overland flow
What does modeling tell us about the intersection of forest management and climate impact at the LTS.
What does modeling tell us?
The difference that irrigation makes
The historical monthly water levels
there is less ET at non-forested well
What do models for forests usually tell us?
how much et and drainage and wtd
how the forest would respond to climate change, is usually increasing temperature or precipitation based on climate models
Land use change impacts
Lu modeling tells us that forest removal and climate change would have pronounced impacts on the groundwater table during dry periods but these impacts may be minor under wet conditions at this typical flatwoods landscape (
FOREST MANAGEMENT & CLIMATE CHANGE
)
Wet years are least impacted by irrigation
quantifying forest water consumption
Water Balance
GW table fluctuation is dependent on ET and precipitation. Changes in ET and P will have direct impacts on the GW table fluctuation
Modeling tells us what is happening within the watershed instead of looking at the WS outlet alone, such as in paired WS studies
LTS nuances
Emergency spraying before storms likely increases the response of the water table
ET increases in March and April
