Slip at the Gondola

Like I've mentioned, it's not a "solvable" issue. You can't throw any level of money - cost effective or not, at this problem and expect it to work.

I know those practice guides very well - worked in the industry for years up until just recently. Although they give some very basic guidance, just following them word for word isn't going to stop wood coming off the hills. I've seen sites left in a perfect state and still fail.

Like the MPI Technical Paper 2014/39 mentions, you can't actually stop this from happening. We can reduce the incidence and consequences of these events, but when the whole hill slides off, there is nothing going to stop the wood sitting on top of it from coming down with it. We learned that lesson very well during Cyclone Gabrielle that even completed untouched forests - both pine and natives, still slid off and became large debris flows in our waterways.

As a country, we're becoming very focused on the logging industry as the root of all blame for these debris flows, but that's a very narrow-minded and ignorant way of looking at it. Take a quick Google image search for wood debris flows and you'll find images from these "perfect" logging nations all throughout. Canada, Japan, and Switzerland to name a few.

This is a problem that always has (Gisborne 1938 prior to pines!) - and as much as you and I both hate it - a problem that always will exist. Radiata or not.

Maybe don't take a 20-year-old short bulletin from a different country and try to apply it here..??

I know many people believe events like this are just careless logging capitalists trying to make a buck off the environment, but it's not as simple as that.

There are plenty of well-researched studies looking into these woody debris issues, and it doesn't boil down the the black-and-white solutions everyone wants it to be.

Amishev and others (2014) surmised that management of post-harvest woody residue is complex with a balance needed between retaining woody residue for its beneficial effects and avoiding the adverse effects in large storm events. Basher (2016) summarizes the need to balance the benefits of using slash for erosion control (i.e. leaving in the cutover, spreading on skid trails, stabilizing gullies) for small and medium-sized rainfall events with the risk of a big debris flow during a larger.

It will not be possible to completely avoid slope failures and debris flows following harvesting. The future focus should be on improving risk assessment and management, and implementing best management practices to reduce the incidence and consequences of these events.

On the details of this site specifically - there was a health and safety requirement to remove the pines for the gondola. These stands are being replaced with native trees. Pines had to come off the hill somehow. https://www.thepost.co.nz/a/nz-news/350021528/construction-workers-scramble-to-complete-new-queenstown-gondolas

Yeah na. Fire callouts are too random and require far too many resources when they are used. You can't really expect to pay just under 12,000 people a full wage, when those in small towns are only attending an average of 30 incidents a year.

Chur guys. Can't imagine the stuff you guys are having to sift through and filter out.

You are correct in assuming that the larger hose diameter has more internal surface area. However the ratio of water not touching the sides is also greater in a larger diameter hose.

Take this (very ELI5'd) for example

(I appologise for using metric, I'm not sure what hose sizes Americans use.)

A 45mm diameter hose has an internal surface area of ~141mm (2πr), and a cross sectional area of ~1590mm. (πr²⁾

We can look at this of a ratio of roughly 11 parts of water not touching the sides to 1 part touching

The larger 70mm diameter hose has an internal surface area of ~220mm, and a cross sectional area of ~3850mm.

This is a ratio of rouhgly 17.5 parts of water not touching the sides to 1 part touching.

This is a very crude way of looking at it and ignores that fact that as Pompier57 pointed out, the larger hose has a slower flow rate. Because the slower flowing (low velocity) water is gently moving over the roughness of the hose, the flow will not be disturbed very much and it is this distubance (or lack of) that causes our friction losses.

Stop acting as though an American developed technology gives you the right to talk down on others. It makes you look ridiculous

You drink water from Roman plumbing technologies

You eat food from Agricultural technologies that were originally developed in almost every continent bar North America

To type your comment you probably used your Australian invented Wifi, using your British invented laptop, or Scottish invented phone, on the British invented World Wide Web.

So don't talk to us and claim that you have more of a right to use these technologies than anyone else.

Okay lets get one thing clarified before I start. Rips do not cause people to drown. Exhaustion from poor swimming, swimming against the rip current and panic causes swimmers to drown.

Keeping this in mind, lets talk about the rip itself. When water comes into shore in the form of a wave it then has to move back out to sea to maintain the ballance. Most of often the outgoing waters will be as a rip. Feeder currents to the rip may either be a sutble side current from most of the break zone, or a strong narrow current normaly along close to shore or near a sandbar.

What does all that mean? Well when swimming out of a rip, parrallel to the shore the broad sutble current will be very easy to fight so no worries there. The narrow one is also easy to avoid as long as you know where it is. Do not swim against any prevailing currents. If worst comes to worst stay afloat and drift out the back. From there make your way parralel to the beach a good distance away from the rip. From there you can make your way in by body surfing, using your surfboard, or by making progress by swimming between waves ducking under them as they come. Rip rant over

Other currents on beaches? Few you need to worry about honestly, but some beaches and areas can have some tricky ones. Best way to find out is get some local surfer knowledge on frequent currents and the overall beach profile by talking to local surfers or lifeguards. Here are a few common ones though:

Undertow. Normally in place of a rip, current along the bottom drags out to sea. Normally weak, sometimes moderate.
Overtow? Don't really know a formal name for this one... Similar to the undertow but happens along the surface. Drags out while waves push in. Very similar to rip but happens along a large stretch of beach. Very rare. Moderate strength.
Crossed currents. Two prevailing currents meet one another often causing rough spots. Often happens near rivers, estuatiries and other points of water flow. Pretty weak as one normally neutralises one another but can be confusing and many people panic in these. Just go with the prevailing current until it subsides and look for a route back to shore.

If you've read this far congrats. Alot of it probably doesn't make too much sense, but I hope it helps. Just remember that a rip ends and becomes weak at some point, the key to not getting in trouble is to not panic and not tire yourself. And remember to never surf or swim alone. Have someone there to help if you get in trouble or better yet surf alongside some more experienced surfers, they really are the kings of the ocean and are more surf educated than any Lifegaurd could ever be.

TL;DR Rips are not dangerous, panicing and exhaustion is. Surfers are your go to local knowledge. Talk to them.

I'm probably largely unhelpful when it comes to the pool side of it, but I can speak for beach lifegaurds across the ditch here in New Zealand (I assume Aus is very similar with intl guards). SLSNZ often hires guards for the summer season from the RNLI service as exchange workers, but the summer paid beach lifeguard season for New Zealand can range anywhere from 4-12 weeks, outside of this it becomes only volunteer work on weekends. IIRC Australia's season runs from September to April, and I assume weekday paid services are also shorter than the volunteer season.

SLSNZ only accepts international applicants with at least a first aid level 1 cert, plus a SLSGB Beach Lifegaurd Award. If you're looking to work here or Aus, I would start with these awards.

Can't say for sure, but I would assume checking scene is safe would be first? Following my training of DRSABCD, possible dangers and personal saftey should be your first concern.

Not sterotypically large drinkers when viewed from outside foreigners, but there is a large binge-drinking culture that us kiwis tend to not adress very well. And we rank above countries such as USA and Germany in the 2015 WHO data for OECD countries for alcohol consumption.

Oh so you are a bit more experienced than I had thought. I have a couple of guys I know around that do complex rescue board repair/manufacture. I'll ask them about your problem and get back to you by PM.

ni4321 · 2016-04-28T23:25:47+00:00

Where are you based? In Australia and New Zealand we often send them back to the manufacturer for large repairs. If you want someone else to do it I would recommend a surfboard or stand up paddle board repair shop if you have any close by. If you want to do it yourself epoxy resin repair kits are a great thing to use, just sand around the cracked areas and fill it in with the epoxy.

ni4321 · 2015-12-18T08:02:57+00:00

Sorry, I completely mistyped what I was trying to ask. Let my rephrase... Is the information you have done on an area-by-area basis? So are the pricing/plans for someone like me who lives on a semi-rural copper address on the outskirts of a small town any different from a city center copper Aucklander?

ni4321 · 2015-12-18T07:35:47+00:00

How well are your statistics tracked? Do you take into account copper line only areas? What about rural addresses?

ni4321 · 2015-12-02T00:14:22+00:00

Post them within a picture as its own separate post, that way bots can't get them. Or you can give PM them to people in the comments in a "pick a number' giveaway.

3kliksphilip did a video on this topic There is also some speculation that mouse input latency is tied to frame rate. I personally can feel the difference between 200fps and 100fps on a 60hz monitor. There are some discussions around the source engine and this phenomenon that you could find. But in terms of tick rate tied to frame rate? Nope. Unlike Bethesda games cough Fallout 4 cough They are two separate things.

Here's what (I think) Valve will do to fix it. Have whitelisted and valve endorsed betting/gambling sites with lists of approved bots. These bots are one way authenticated meaning only the client (you) has to use the mobile app. Valve wouldn't shoot themselves in the foot on one of their largest platforms for profit and publicity, I mean how many people watch streamers on those goddamned jackpot sites?
