561 - Ecohydrology
course deals with hydrologic and ecological mechanisms underlying
climate-soil-vegetation dynamics and land-water dynamics.
The evolution of terrestrial ecosystems depends on the need
of vegetation for inputs of light, water, and nutrients.
These inputs are variable in time and space, and how they
are assimilated depends on plant characteristics and ecosystem
Thus, vegetation plays an active role as both cause and
effect of the space-time dynamics of soil water and climate.
Specific topics will include preferred states in spatial
distribution of soil moisture, hydraulic limits to plant
water use, ecological optimality, vegetation-hydrology linkages
at catchment scales, carbon and nutrient cycling, and vegetation
Graduate student status. Students with a background or interest
in physical geography, geology, or civil & environmental engineering
are particularly encouraged to take this class.
There are no exams in this class. We will run this course primarily
as a seminar. For about 2/3 of the time there will lectures,
at other times each student will be given the opportunity to
lead discussion. Grades will be based on a term project
presentation 7.5%), a mid-term paper (20%) and presentation (7.5%)
on an assigned topic, leading discussion on up to two papers
depending on class size and time available, and participation
in discussion throughout the semester (15%). There also
some in-class application of ecohydrologic models.
1. Soil water dynamics
2. Land surface energy budgets
4. Ecohydrologic optimality theory
5. Net primary production
6. Carbon and nitrogen cycling
7. Vegetation competition
