Coastal Landforms and the Processes

By: Jaimee Watson and Sarah James

Different types of erosion:

Hydraulic Action

Hydraulic action occurs when the motion of water against a rock surface produces mechanical weathering. Most generally, it is the ability of moving water (flowing or waves) to dislodge and transport rock particles. Within this rubric are a number of specific erosional processes, including abrasion, attrition, corrasion, saltation, scouring, and traction.[citation needed] Hydraulic action is distinguished from other types of water facilitated erosion, such as static erosion where water leaches salts and floats off organic material from unconsolidated sediments, and from chemical erosion more often called chemical weathering

Humanities Beach Excursion 2013

Monday, May 6th, 8:30am-3pm

Noosa National Park and Sunshine Beach

Noosa Heads, QLD

Knowledge gainned on the excursion

We learnt about all of the different types of erosional processes and that they didn't just occur on the beach, they also occurred on rock.

We learnt the most common form of erosion witch was, Hydraulic action.

We also learnt what a berm, swash zone, Gutter, Frontal dunes and Secondary Dunes.
