Synopsis: Water, its
availability and its unique physical properties, is a partner with solar
radiation among the primary agents that drive weather and climate. The
cycling of water through the Earth's environment is the yin and yang of water
− a benefactor sustaining humankind's food supplies, facilitating
transportation and producing power, while conversely an adversary responsible
for droughts, floods, wildfires and landslides. If the climate is changing,
then, without doubt, water, being the most abundant greenhouse gas −
far more so than the nearest candidate, CO2 − will be a principal
player in the atmosphere, land processes, in the oceans and rivers,
and in the soil. But, how this role will be played out remains elusive to
science; we first need to understand the "normalcy" of water
processes. We need to understand the normal behavior of water − even as
we need to understand what are normal extreme events. This course is a
qualitative/semi-quantitative introduction to the underlying causes of
floods, droughts, wildfires, and hurricanes in the context of environmental
processes globally driven by the unique character of water, and by its
regional abundance or scarcity. We explore the foundations for understanding
the physical mechanisms by which water is transported throughout a hydrologic
system, emphasizing the fundamental inter-coupling of atmospheric, surface,
soil and ground water. While providing background for future studies, the
course is primarily designed to enable informed citizens to thoughtfully
critique and comment on fundamental issues of public policy. A pre-college
math and physics background is expected. |

This course is primarily
designed to be a forum in which humanities and science students might explore
topics of common interest. |
