GEOG 210 Physical Geography

An introduction to the physical elements of geography
and the environment in which people live. The
focus is on natural processes that create physical
diversity on the earth. Major topics are weather and
climate, vegetation and soils, landforms, ecosystems,
their distribution and significance.

GEOG 320 Geomorphic Processes

Study of landform processes at the earth’s surface
including the work of water, wind, and ice in erosion,
transportation, and deposition on land and
sea. The significance of geomorphic processes to
human activities is included. A one- to two-day
weekend field trip is required. Three lectures; one
3-hour lab. This course is the same as Geology
374; course may be taken only once for credit.
Recommended prerequisites: Geog 210 and Mth 111. 

GEOG 345 Resource Management

Survey of natural resources, their occurrence, and
their management. Primary focus will be on the
United States, with case studies from other countries
and regions. Recommended prerequisite:
upper-division standing.

GEOG 4/507 Fluvial Geomorphology

Seminar (Credit to be arranged.)

GEOG 4/515 Soils and Land Use

The origin, development and distribution of soils
and the significance of soil to man. Examines the
importance of soil to landforms, vegetation, and
ecological development. Major emphasis is given
to land use potentials and limitations on various
kinds of soils with focus on urban and agricultural
settings. There are two half-day field trips.
Recommended prerequisite: Geog 210.

GEOG 4/520 Field Methods in Physical Geog.

Introduces students to field methods in physical
geography. The goal is to familiarize the student
with field techniques including research and sampling
design, field measurements and mapping,
data analysis and report writing and the use of
field equipment. Field and lab exercises will focus
on the examination of natural patterns and processes
and those resulting from human activity.
Techniques involving vegetation sampling, soil
description, microclimatic conditions, and geomorphologic
processes will be covered.
Recommended prerequisite: eight hours of upperdivision
physical geography or graduate standing.

GEOG 4/589 Building a GIS Database with GPS

Develops knowledge and skills necessary to use
the global positioning systems (GPS) to collect,
process, and use geographic data. GPS theory and
techniques through field survey experiences.
Collect and integrate spatial and non-spatial data
within an integrated geographic information system
(GIS) framework. Prerequisite: Geog
488/588.
