Operational hydrology and water resources engineering have utilized these measurements for the design and operation of water resource systems and the forecasting of hydrologic systems. There has been a long recorded history of hydrologic data collection in support of operational hydrology going back to ancient Chinese and Egyptian times. In modern industrialized countries, hydrologic data collection has focused on streamflow, precipitation and basic surface meteorological data which are sufficient for the design and forecasting needs of the water resource engineers: primarily the design of water supply and flood protection works, which requires long- term records for river flows, and the forecasting of floods, which requires (spatially) accurate precipitation measurements.

We have been teaching the course twice a year since that time. The use of the Internet for the delivery of higher education courses has dramatically increased especially at the University of Toledo where over 6,000 students a semester take distance-learning courses. However, our clientele of in-service teachers seem to have more than their share of technological problems, possibly due to the length of time since their graduation and lack of computer knowledge. Overcoming this technological hurdle has proven to be a major obstacle in the successful completion of the course, and, indeed, is the major cause of students' withdrawals from the course. Additional problems we have needed to address are the correct use of Internet materials, up to and including blatant plagiarism and computer etiquette. In our presentation we will discuss our findings from pre- and post-course surveys on teachers' comfort levels with the medium, as well as innovative ways we have dealt with other problems unique to distance learning.

Here, we synthesize 171 site-months of flux measurements of CO2 based on the eddy covariance method from 13 lakes and reservoirs in the Northern Hemisphere, and quantify dynamics at multiple temporal scales. We found pronounced sub-annual variability in CO2 flux at all sites. By accounting for diel variation, only 11% of site-months were net daily sinks of CO2. Annual CO2 emissions had an average of 25% (range 3%–58%) interannual variation. Similar to studies on streams, nighttime emissions regularly exceeded daytime emissions. Biophysical regulations of CO2 flux variability were delineated through mutual information analysis. Sample analysis of CO2 fluxes indicate the importance of continuous measurements. Better characterization of short- and long-term variability is necessary to understand and improve detection of temporal changes of CO2 fl...

Using a range of data sources including sketch maps, interviews, and neighborhood-based student projects, this paper addresses two research questions: (a) How did students’ spatial narratives of their community change as a result of using a culturally responsive teaching approach to explore neighborhood challenges? (b) How does a culturally responsive teaching approach and a critical geography perspective support spatial justice among youth?
