Daily Objectives #6 (January 29, 2004)                                        Dr. Sanders

By the end of today's class, you should be able to do the following:

New objectives

v List the factors that influence and determine the shape of a hydrograph.

v Separate a hydrograph into its two main components: runoff and baseflow.  (Here's some really neat software that will do this automatically.  It's rather new and its possibilities are yet to be explored.  Lots of research potential here!  Warning: once you click to go to the site, depending on what browser you are using, you may not be able to click "Back" to get to this Objectives page again.)

v Describe instruments used to measure precipitation, evaporation, evapotranspiration, and streamflow.

v Review for Exam #1, which will be held on Tuesday, February 3.  Click here for a review page.

Loose ends

v Write in your own words a description of the meaning of Effective Uniform Depth (EUD).

v Use the dot-grid method to find a map area.

v Use a planimeter to find a map area.  (Find the area of Orland Lake on the topographic map provided.  Please post your measurement by writing it on the chalkboard.)

v Use the arithmetic mean method and the Thiessen method to calculate EUD of precipitation for an area.
