The Wisconsin roots of ground water hydrology.

Daniel W. Mead, pioneer educator, ethicist, and consultant.

Introduction An early textbook in hydrology (Mead 1919) contains a remarkable chapter on ground water as well as two chapters on geology. The author, Daniel W. Mead, a professor of hydraulic and sanitary engineering at the University of Wisconsin (now the University of WisconsinMadison), based the text on lecture notes (published earlier, Mead [1904]) for his course in general hydrology. In fac...

Predicting the Summer Temperature of Small Streams in Southwestern Wisconsin1

One of the biggest challenges in managing cold water streams in the Midwest is understanding how stream temperature is controlled by the complex interactions among meteorologic processes, channel geometry, and ground water inflow. Inflow of cold ground water, shade provided by riparian vegetation, and channel width are the most important factors controlling summer stream temperatures. A simple ...

Irrigation effects in the northern lake states: Wisconsin central sands revisited.

Irrigated agriculture has expanded greatly in the water-rich U.S. northern lake states during the past half century. Source water there is usually obtained from glacial aquifers strongly connected to surface waters, so irrigation has a potential to locally decrease base flows in streams and water levels in aquifers, lakes, and wetlands. During the nascent phase of the irrigation expansion, wate...

Below-ground Processes in Gap Models for Simulating Forest Response to Global Change

Gap models have a rich history of being used to simulate individual tree interactions that impact species diversity and patterns of forest succession. Questions arise, however, as to whether these same models can be used to study the response of forest structure and composition under a changing climate. In contrast to many process-based models, gap models have traditionally been based on rather...
