Encyclopedia
Bremer River is a river
in Western Australia
that rises near Jerramungup at the border of the Yilgarn plateau. The river flows in a generally south-easterly direction and the river valley becomes steadily deeper as the river approaches the coast
where it has eroded the Pallinup siltstone
deposits that deposited over the underlying granite
.
The name Bremer River was first recorded in 1919 and is believed to come from the town of Bremer Bay
that is located on the Wellstead estuary where the river flows into Bremer Bay.
The river has two minor tributaries
; Devil Creek and Lizzie Creek.
About 80% of the catchment area has been cleared for agriculture, mostly for cropping and grazing.
The river is saline
varying from 3-4‰ to 150‰ depending on the season.

Coast
A coastline or seashore is the area where land meets the sea or ocean. A precise line that can be called a coastline cannot be determined due to the dynamic nature of tides. The term "coastal zone" can be used instead, which is a spatial zone where interaction of the sea and land processes occurs...
where it has eroded the Pallinup siltstone
Siltstone
Siltstone is a sedimentary rock which has a grain size in the silt range, finer than sandstone and coarser than claystones.- Description :As its name implies, it is primarily composed of silt sized particles, defined as grains 1/16 - 1/256 mm or 4 to 8 on the Krumbein phi scale...
deposits that deposited over the underlying granite
Granite
Granite is a common and widely occurring type of intrusive, felsic, igneous rock. Granite usually has a medium- to coarse-grained texture. Occasionally some individual crystals are larger than the groundmass, in which case the texture is known as porphyritic. A granitic rock with a porphyritic...
