Muriwai Information
Formation of the Land
Geomorphologic Processes
This is about how the Muriwai Coastal Environment (M.C.E.) land has been created and shaped over time. I.e. it’s all about Rocks! The west coast’s geomorphology has been influenced by tectonic processes (rocks), alluvial processes (water) and climatic processes (weather).

Hydrological Processes
Hydrological Processes refer to water. Waves are continually affecting Otakimiro Point (i.e. the Headland). At Muriwai, waves are responsible for shaping the coast everyday (and night!).
Hydrological Vocab * The movement of waves back down the beach. * The movement of waves up on to the beach. * These occur on shores with a steeply angled shore. The waves curl over and crash loudly. They are destructive. * These occur on shores with a gentle angled shore. The waves spill over. They are constructive. * The process by which the direction of a wave is changed when it moves in to shallower water. * The energy of water impacting on a cracks and joint. Air is compressed into the space, leading to erosion. * When particles of sand or rock further abrade the rock surface. * When the waves wear away at the base of a cliff, often forming a notch. * The wearing a way of rocks after they have been removed from the cliff face. * The distance a wave travels without interruption
WAVES
The Power of the Sea
Waves are formed by energy of the wind blowing over long ocean distances.
Waves at M.C.E.
The size of a wave is determined by; * The strength of the wind * The amount of time the wind has been blowing * The fetch
Winds are often over 16kph and S.W in direction. Waves that reach Muriwai Coastal Environment have travelled from Australia.

Wave refraction
This is the process by which waves undergo a change of direction as they approach

    Waves which are mainly caused by wind travel in little circles or orbs. Waves decrease in velocity as they enter the shore. The top of the wave is called a crest and the bottom is called a trough. The wave crest which will break as it enters the shore. You will view that in this week's animation. Surface waves should not be confused with Tsunamis or tidal waves. Those are caused by the energy of Earthquakes or other natural disasters. They are massive amounts of water moving out in every direction.…

    Ocean waves are caused by many different factors. Usually waves are created by the wind; the wind transfers its energy to the water, through friction between the air molecules and the water molecules. The stronger the winds, the stronger the waves. Water waves usually do not go horizontally, they only move up and down. Some factors that also cause waves are tsunamis, earthquakes, and hurricanes. Surprisingly, wind speeds, the distance over which the winds blow, and the time that the winds are in contact with the water all determine the height and speed of the wave. Waves can travel thousands of miles from their source of “origin”. But it’s not the water moving, it’s the energy. As a wave approaches shore, friction between the bottom of the wave and the…

    These are examples of how humans have physically impacted the beach and its structure. The flight deck is a human residential block of units on the edge of the beach. This unit block has massively affected the shaping and the beachfront of that area of Collaroy beach. The coastal processes that are threatening the erosion of the beachfront developments are, Erosion/Accretion Cycle (or sediment budget), destructive storm waves and king tides. These processes are slowly undermining the building and causing the dune under the units to become unstable and dangerous for people living in and around them. Also the salts from the waves blowing onto the units causes the metal to rust and the foundation of the building and balcony handrails to be at risk of being unreliable and…

    * The sand dunes on the beaches. This area is affected by wind erosion as well as the tides if adequate vegetative cover is not present. The main type of erosion, from the sea, takes the sand from the sand dunes as well as the rest of the beach in a rip. The sand is then pulled out to sea where it forms a sand bar. On calmer days, the sand is brought back to the beach.…

    Purpose: To investigate tsunamis Introduction:I have always been fascinated by tsunamis. I have to say that when I vacationed in Hawaii and snorkeled in the Pacific Ocean, I did give a fleeting thought to tsunamis. In the last activity, I mentioned that the characteristics and behaviors of waves that you learned from the video could be applied to other waves. As you complete this activity, I want you to think about the similarities between the rogue tsunamis and the common waves we have studied.Materials:none Procedure: 1. Answer the question based on your exploration on the tsunami website. 2. Submit the assignment according to the directions below.…

    Whenever bedrock is exposed, it weathers. Weathered rock often has a different color or texture from neighboring unexposed bedrock. Most significant from a topographic standpoint, exposed bedrock is likely to be looser than the underlying rock. Blocks or chips maybe so loose that they can be detached with little effort. Sometimes pieces are so “rotten” that they can be crumbled by finger pressure. Slightly deeper in the bedrock, there is firmer, more solid rock, although along cracks or crevices weathering may extend to considerable depths. In some cases, the weathering may reach as much as several hundred meters beneath the surface. This penetration is made possible by open spaces in the rock bodies and even between the mineral grains. Subsurface weathering is initiated along these openings, which can be penetrated by such weathering agents as water, air, and plant roots. As time passes, the weathering effects spread from the immediate vicinity of the openings into the denser rock beyond.…

    Rogue Waves

    These huge waves are called rogue waves—or monster or freak waves—and can be encountered during bad weather storms or even in calm seas, but the fundamental aspect is that they appear with little warning. The biggest problem is the lack of scientific data from shipboard measurements of such waves because of their propensity to appear quickly and without warning. Rogue waves can also disappear as quickly as they form. Scientists have been studying the formation and characteristics of rogue waves with the goal of creating an accurate prediction and detection method to mitigate the potential damage of these waves.…

    The Wedge If you like to surf or hit the waves, the infamous "Wedge" in Newport Beach is something you have to experience at least once in your lifetime. Although The Wedge isn't classified as a wave, it's actually a 20 foot plus battering ram that was created by sheer intelligence. The way it heaves, throws, and bends behaves in ways other waves can't begin to comprehend. If you look at it up close, you'll notice that The Wedge is a combination of two waves that join together, resulting in a massive slingshot that is capable of sending…

    Last Tuesday, we took a trip to Huntington Beach and observed the ocean, sand, waves, tides, life on shore, wind, currents, sea bedding, sediments, and the fully developed sea. It was around 4 PM when we arrived at the beach, and it was about 77 degrees Fahrenheit. The coastline of the shore is a curve that faces southwest. Winds are disturbing forces that move the waves, and they generate every time there is a density boundary. The cool winds were coming very strong from the West at 251° that it wasn’t a good day to surf at the beach. The waves are movement of energy, and the waves were about 4-6 feet high, but with such hazardous wind conditions, nobody was surfing. If they were to try to surf, the top of the wave would topple over because of the decrease in wave speed and wind.…
