|
What is salinity |
Amount of dissolved salts in water |
|
|
|
Why does salinity impact electrical conductivity? |
Pure water has poor conductivity. The salt increases the electrical conductivity |
|
|
|
How does a hydrometer work? |
Finds density of water depending on how much the hydrometer floats |
|
|
|
What factors impact celerity for deep water wave? |
the celerity depends on the wave length. |
|
|
|
What impacts celerity on a shallow water wave? |
Water depth because it interact with the bottom |
|
|
|
Groin vs jetti |
Jetty is built to protect inlets between barrier beaches, groin is used to restore beach sand and shield property from wave damage |
|
|
|
How does temp and salinity impact density |
Increasing salinity increases density. Temperature has even a greater effect,but colder water will increase density since the molecules slow down and stick closer together |
|
|
|
Water mass? |
A large body of seawater that is characterized by salinity and temperature |
|
|
|
What causes longshore currents? |
Wave refraction |
|
|
|
Summer vs Winter profiles |
Winter has more aggressive weather and waves. Pounding the shore and removing sand from the beach. Summer restores the sand lost during winter |
|
|
|
Seawall |
Used to protect a structure from waves and erosion |
|
|
|
Beach profile. Label and draw |
Backshore =dune,berms, shoreline Foreshore Nearshore Offshore |
|
|
|
Conditions of a fully developed sea? |
When energy lost from breaking waves is equel to energy gained from winds. |
