Muriwai Coastal Environment Essay Example

Coordinates: 36°49′S174°25′E / 36.817°S 174.417°E / -36.817; 174.417

Muriwai, also called Muriwai Beach, is a coastal community on the west coast of the Auckland Region in the North Island of New Zealand. The black-sand surf beach and surrounding area is a popular recreational area for Aucklanders. Gannets nest there in a large colony on the rocks.

Location[edit]

Muriwai is approximately 17 km west of Kumeu, 42 kilometres northwest of Auckland city, at the southern end of an unbroken 50 kilometre stretch of beach which extends up the Tasman Sea coast to the mouth of the Kaipara Harbour. One of several popular beaches in the area (others include Piha and Karekare), it experiences a population explosion in summer when Aucklanders head to the sea. It is in the Rodney Ward of the Auckland Region.

Statistics[edit]

At the 2013 Census, the usually-resident population of Muriwai Beach was 1,131. The median income of people in Muriwai Beach was $39,500, compared with $29,600 for Auckland. The town is over 93% white European. The unemployment rate was 4%.[1]

Activity[edit]

  • Surfing is the main pastime at Maukatia (Maori Bay) and Muriwai Beach. Other pastimes enjoyed at Maukatia include paragliding and hang gliding, especially when the prevailing southwesterly wind provides favourable conditions.
  • Fishing is also popular, although dangerous in many places.
  • Bush walking is encouraged, with boardwalks in place, and the 'Hilary Trail' passes through Muriwai.
  • Driving along the beach is popular, especially at fishing contest time, although vehicles have been mass stranded in past years.
  • Surf boards, surfing tuition and sand yachts are available for hire at the Muriwai Surf School near the beach.
  • There are many mountain bike trails up in the pines, mainly downhill and freeride trails.
  • The beach was used extensively for motor racing from the 1920s through to the 1940s.[2]
  • Horse riding is popular along the beach, as well as through the extensive tracks behind the sand dunes. Access is also available through the Woodhill Forest Equestrian Park.[3]

Geology[edit]

Sand and rock (sedimentary), older volcanic material, with many concretions and layers in the cliff walls. A blowhole plays often. The shore platform is also well jointed, with the main rock type being piha conglomerate.

Muriwai Beach has black sand, caused by the iron content derived from the ancient volcanoes in the area, including the large "Kaipara Volcano" which was situated offshore from the Kaipara Heads, and erupted 23-16 million years ago.[4] The black sand is moved up the west coast of the North Island by longshore drift. The area has retained much of its natural beauty and isolation.

Muriwai Regional Park[edit]

Much of the land at the southern end of the beach is part of the Muriwai Regional Park. Maukatia (Maori Bay) to the south is separated from Muriwai Beach by Otakamiro Point, with its steep cliffs and rocky nesting areas that are home to the region's only colony of Australasian gannets. The site of the gannetry has been identified as an Important Bird Area, by BirdLife International.[5]

The Regional Park includes a golf course along Coast Rd, and the area north of Okiritoto Stream is known as the "Five Mile Strip" or "Five Mile Block" as this is its approximate length. A horse park (parking area for horse floats and trucks to unload) is located just to the south of Okiritoto Stream. 4WD access on to the beach is also provided at this point.

The Five Mile Block provides recreational trails for both walkers and horse riders.[6] Cyclists enjoy the Coast Rd as far as the top of the Regional Park (but are not permitted into the adjoining Woodhill Forest) by the forest managers. Dog walkers also frequent the area, as it provides a wide range of off-leash walking opportunities.

2013 shark attack[edit]

See also: Shark attack

In February 2013, filmmaker Adam Strange was killed at Muriwai Beach while swimming about 200m offshore, when he was attacked by a small group of great white sharks.[7][8] As a result, Muriwai Beach was closed for a number of days.[9] Initial reports suggested the culprit was a bronze whaler, but it was later deemed more likely a great white was to blame.[10] It was the first fatal shark attack in more than three decades in New Zealand.[11]

Hi there,
I was wondering who else is on level 3 geography this year. I am slightly confused as to when the big Taupo eruption was. One source said 232AD but then several others said 181AD and yet another said182AD. I looked it up on the internet but found no satisfactory answers because the results I found were all different, supporting different days.
Does anyone else know? Is anyone Else studying the Tongariro region for the natural landscape paper?
Thanks,
old2it

Hi evilgenius, thanks, I think I'll go with 232AD.....there seems to be plenty of support for it......maybe that was the biggest one and there were smaller ones at the later dates.

Hello everyone,
I am looking for excellence exemplars for the Geography standard 90701 (natural processes) that are specific to years other than 2009 or 2011.
I have already found the 2009 and 2011 exemplars online on NZQA website but I would like the exemplars of other years.

I would appreciate it very much if you directed me to a link of the exemplars. At this stage, even achieved or merit exemplars will suffice.

Thank you in advance for your help.

I'm not sure if there are any others. I think the questions have been structured differently over since 2009 and so perhaps there are none? If they aren't on NZQA (the first place I'd have suggested) maybe there aren't any. The other alternative is asking your teacher if they have any old ones lying around.
Do you have th AME Geography Level 3 book? I had the level 1 one and that helped since it gave good questions to practice and I guess the answers are set at excellence levels?
I hope that helps but I don't know what else to suggest.

Hi

for 90705 we did a study on a local river, my research question was how rock size changed at different places along the river and if the speed of the river effected this.

90706 we have not done yet but i think it on water quality in lakes in Rotorua.

Thanks evilgenius...good luck with 90706.
We got to chose what we did but had to ahve teacher approval. for 90705 I'm studying water quality on the farm I grew up on. We are encourgaed to use that same issue for 90706, but just say way something like water quality is controversial..... Thus far I'm still working on it but hopefully am on track for an E!

Can anyone please tell me what the difference is between natural landforms AND natural features is.

Or do they mean the same thing?


Oh, and thank you to old2it for replying...I don't have an AME book but don't they give exactly the same questions as the NCEA papers anyway?

Hi there,
I'm starting AS 90707.
I'd liek to study earthquakes, which was one of the options given to us. The main earthquakes are around plate boundaries as this can be shown on teh map, forming a clear pattern. One question mentions what processes affect this pattern. Does that mean how earthquakes are form?

Hi everyone

So I am doing natural processes with the case study being Muriwai Coastal Environment (MCE).
I am struggling a lot with parts of this paper so could someone please help me clear out these questions?

- Would we get a question on 'interaction of processes'? And if so, which processes would we talk about? :/

- Does anyone know which diagram to use for the temporal variation on Muriwai Beach?

- If the question asks for Distribution of Natural Features, how exactly would we structure our essay? As in what do we talk about? and where do the processes come in?

- Is there a certain amount of processes we must talk about in each essay (even if not specified in the question)?

Thank you in advance for any help!

Which process have you learnt? I learnt:
-Fluvial
-Aeolian
-Volcanic , etc..
Yes it is possible to get a question on the interaction. Talk about how they influence each other. Eg: Eruption from Mount blaha blah caused ash to land on so and so... This was also carried by wind (aeolian) to ... etc. (I have just linked volcanic with aeolian)

Quote:

Do not quote me on this. But I would...
Talk about where the features are and why they are there in that particular area.
You can use processes to explain why they are present in that area.

Quote:
- Is there a certain amount of processes we must talk about in each essay (even if not specified in the question)?


I suppose so...it really depends on the question...
But there are sometimes when you must try your best to write almost nothing on processes (eg: if the question asks to discuss human modifications (by itself; ie: NOT: human modifications and its impact on the processes)
See schedules as well...

Sorry if I wasn't of much help.
Kindest Regards,
God bless you.

Hi there mathpower and old2it

firstly, thank you so much for the help!

The processes I'm studying are categorised into geomorphological processes, wind processes and wave processes, and they include
-volcanism, saltation (aeolian deposition), longshore drift, wave action (abrasion, attrition, corrasion) etc...

so these processes are really specific to the setting of Muriwai which is why it's a bit difficult to get specific help, but your suggestions made my understanding of the questions a lot clearer, thank you

Sorry, I'm studying migration rather than tourism.
Here are some suggestions but I'm probably wrong.....
Social relates to people: multiculutral city?
Economic relates to money: Increased wealth through tourism spending.....
Political: relates to rules: maybe increased safety rules for equipment?
Id ask your teacher.....

Hey guys,

I was just checking out the skills list for level 3, and realised that our teacher never taught us how to calculate slope angles.
I'm assuming that you find the change height using contour lines and the distance using the scale and then use trigonometry?

If anyone could clarify this or provide some links it would be much appreciated!

Good luck for your exams!

hi everyone!

I have something I want to clarify
So for the 'distribution of natural features' question
I'll be preparing for it by locating 4 features on a map of Muriwai Coastal Environment
and then for the essay part I will be writing about the reasons for distribution for 2 features
I have prepared one feature which will be Muriwai Beach itself

But I need to prepare another feature! I don't have good class notes at all so I can't find material anywhere

could someone tell me another feature I could do (specific to Muriwai!) and tell me briefly the reason for distribution?

Your welcome riema

distantdiaondsky- cool name.
As said before, I'm not study that. However would features include rocky beaches, sand dunes etc?
I just googled it, and putting my knowledge to that test, there looks like cliffs, a river and perhaps and island?
Is it possible to contact your teacher and just ask?
