COURSES

SP'19 OFFICE HOURS: THU 1:00-2:20 | SE2-374

ESS 110 Hydrology & Climate

Basics of the hydrological cycle and the global climate system. Fundamentals of surface water hydrology, hydrometeorology, evaporation, precipitation, statistical and probabilistic methods, unit hydrograph and flood routing.

Syllabus

ESS 112 Subsurface Hydrology

Hydrologic and geologic factors controlling the occurrence and use of groundwater on regional and local scales. Physical, mathematical, geologic and engineering concepts fundamental to subsurface hydrologic processes. Introduction to ground-water flow and transport modeling, with emphasis on model construction and simulation.

Syllabus

ES 228 Environmental Modeling

An advanced study of modeling environmental sciences. The first half of the course a survey of common modeling approaches of environmental phenomena. In the second half, student work on individual projects that involve modeling environmental systems or processes. Often students work on problems related to their thesis/dissertation area. (Graduate Only).
