Texas Student Involvement in Coastal Monitoring Studies
Texas High School Coastal Monitoring Program Sponsors
• Provide high school students with an inquiry-based learning experience through investigation of beach changes.
• Increase public awareness and understanding of coastal processes and hazards.
• Obtain a better understanding of the relationship between coastal processes, beach morphology, and shoreline change, and make data and findings available for solving coastal management problems.
THSCMP Goals
Student Collected Data• Topographic transect oriented perpendicular to
the shoreline– measured from the same starting point landward of
the foredune and oriented in the same direction.
• Estimates of processes acting on the beach– wind direction and speed; wave direction, height,
and period; and longshore current direction and speed
• GPS survey of the vegetation line and shoreline– quantitative data on the position and trends of the
shoreline and vegetation line
Topographic Profile
Determine vertical changebetween front and back Emory rods using siting level or horizon
Measure horizontal distance between Emory rods
Wind and Wave ObservationsWind meter
Longshore Current Measurement
Shoreline and VegetationLine Mapping with GPS

Summary• THSCMP provides Texas students with a real-world
learning experience.
• THSCMP delivers valuable data to the State of Texas for use by students and teachers, scientists, coastal managers, and the general public.
• Data collected by THSCMP has proven beneficial to BEG researchers and coastal managers in numerous scientific studies.
• Future data collection will further enhance our understanding of the Texas coast as well as continue to educate middle and high school students on coastal issues.
