Not exactly sure what to write about...

Well, my mission to get rid of all of my stuff continues...  There is still a lot of stuff that needs to go, but progress is occurring, and the piles are getting smaller.

I decided to get through the coin collection first, and it seems that I actually did have a few dollars worth of coins in that box, I am going through the coin supplies next.  Then I am going to sort and do a blast of stuff on craigslist, ending with maybe a rummage sale when I get towards the ends.  There will also be a bunch of stuff heading to goodwill and who knows where else...

I also found a place to get rid of all of my electronics recycling locally.  Going to be bringing them a truck load so that I can free up the boxes and prepare another truck load....

Also going is a bunch of larger electronics that are still good, usable, and worth something that I have picked up, waiting for the weather to get more hospitable, and being able to do that run when I am back in school and can just go downstairs and use the UPS station at the school will be ideal.

Speaking of school, only three weeks left of break!  Then back for a semester of fun!

Also, you may have noticed a bunch of short posts, I found out how to blog from my phone, yet another way to be anti-social while at the bar!

In the Ebay world, I have 16 auctions up and running as of right now, 120 bids and the first auction does not end until Saturday...  Next Saturday!  I started them all out at 99 cents and they are going berserk!  In the first day I had one auction rack up 37 bids!  I am interested to see where this week goes, I already have 4 auctions in the 50-100 range, and two have broken through 100 dollars.  I will keep an update as the week goes on as for how things are going.

Also, it is cold, really f'n cold, and I am intentionally running myself out of cigarettes with no way to get to the store.  The truck is safely tucked away in the end of the big building where it will stay until the weather returns to at least a little closer to the positive side of the Fahrenheit scale.

The coldest I have seen so far tonight as for temperatures is 35 below, I will see if anyone is testing that in a few minutes, ah hell, lets see if they have updated....  Still 33 below at Crane lake, although Cook is coming in a close second at -31...

Well, the ebay auctions have hit 140 bids while I was writing this and I am now over a three week total of two grand!  The summer field camp and epic road trip around the Western US is getting funded!  In the time it took me to write that sentence and take a sip of beer I hit 148 bids, this is nuts!  I am only 37 dollars from beating my insane total from last week on the final auction prices!

It looks like I have some power-ebay bidders that are working to help me out on my mission to get a fully funded vacation.  I am completely fine with this....

Saturday is listing day! Bring on the EBAY!

I am listing more stuff on ebay, three auctions up already, and one of them already got a bid!

This is what I am going to do all day, well this and toss in firewood so I can stay warm in this coming week, it is supposed to be freaking cold!  They are predicting four days of ambient temperatures of 17, 27,. 21, and 15 degrees below zero, even colder up over the hill they are predicting 35-40 below, with wind chills of 70 below!  I am going to hide in my basement, fill the wood stove, and stay warm for the next four days!

Might pick up a 12 pack of beer since I will not be going anywhere, and maybe go tuck the truck into the barn since I have no intention of doing anything other than watching ebay auctions and playing Kerbal Space Program....

Kerbal Space Program

I finally successfully landed a kerbal on an extra-planetary body today.  That took a lot of work.

So, I decided my first landing target would be Jool, yeah it is way out there, and as it turns out retracting the solar panels before entering the atmosphere would have been a good idea, but it worked.

That and I got a shitliad of science points, which I can now use to get new science equipment,  which I am going to use to get more science points....

I think the main point is that I looked at the weather forecast and they mentioned an ambient temperature of 27 below zero.  If it gets that cold I am not going anywhere, I can stay in my basement for three days tending the fireplace and the ebay auctions.   Sounds like a plan to me!

And school news

In other news the professors have started to post grades, passed both of the classes that have been posted so far, and those were the only two I cared about, I already know I have an A in sed-strat, the perfect test average and string of perfect labs pretty much guarantee it, and geophysics I was doing well, everything was making sense.
The end result is that the balloon bandit survives anotger semester, still waiting to find out how many I have left.  Hopefully I will be done at the end of summer.
We will wait and see.
The balloon bandit strikes...
An update from the next morning, the rest of the grades are in, all is well on the Western front...

Christmas comes around

I make no secret of the fact that I am not a huge fan of Christmas,  I kind of consider it  to be a way to introduce children to greed. But this year was pretty good,  what did I get you ask? Four pairs of jeans, a pack of underwear,  two tee-shirts...  all totally useable, screwdriver set and color pencil set, useable, homemade salsa and chips, edible,  gloves, needed, boomerang,  fun and small, some books and magazines, interesting. ..
There is a theme here, no meaningless crap, well there was a hat for the cat, but that was more for the cat then for me, it went to me because he knew I would post pictures.

Looking into the Tiny House movement...

I have been researching "Tiny Houses" for a while now.  I like the idea of being able to pick up and leave if you either get the urge, or get the need.  The problem is that not a lot of places are very forthcoming on the plans that they have for their houses.  Then today I saw something awesome in the newspaper.

Occupy Madison has decided to start building Tiny Houses from recycled materials for the purpose of housing the homeless.

Ok, that officially qualifies as awesome.

I am going to see if I cannot get a plan from them so I can see how they are building their tiny houses, I have construction skills, and as it turns out my sister just got a bandsaw for Christmas.  There is a possibility that some good could come from all of this.

I will need to upgrade my truck if I have any intention of towing something that big, but I should not have to upgrade it that far, find an old Dodge diesel or something along those lines, so I am not getting completely gouged on the fuel costs, and can safely tow a 3000-4000 pound trailer.

Upon further research I think the best bet would be a Toyota Tacoma, all you have to do is put a real hitch on it and it will pull that size of a trailer with little issue.  That and I miss Zippy the Wonder Truck, would love to have a Toyota again.

The June 2012 flood was a disastrous weather event that occurred from Tuesday, June 19th, through Wednesday afternoon on the 20th. In the week prior to the storm there had been moderate rainfall events that had saturated the ground. Reports from show that the Duluth Airport had recorded 1.76 inches of rainfall on June 14th and another .95 inches on June 17th. This saturation caused the heavy rainfall on the 19th to no longer soak into the ground, quickly raising the levels in drainage ditches, creeks, and rivers due to increased overland flow.
The weather event was set up by a large body of warm moist air being overridden by a cold front. The storm built over northeastern Minnesota with a direction of travel such that the large, slow moving thunderstorms tracked over the paths of each other. This generated a combined effect resulting in a huge quantity of precipitation. The post storm reports showed that rainfall ranging from 8-10 inches fell over a large area in 24 hours (Graning, 2012).
            Lester River at the eastern end of Duluth developed a particularly impressive mouth bar which showed up as an arc 55 meters from the normal terminus of the river. The remnants of the bar are still visible today.
            The Lester River and Amity Creek watershed drains a total area of 52.1 mi2.  This large area, combined with the enormity of this five-hundred year flood event ("Flooding Rains in Northeast Minnesota: June 19-20, 2012.") and the steep slope of this river led to a massive mobilization of sediment and subsequent deposition.  This deposition accumulated most dramatically at the mouth of the river as a large offshore mouth bar.  Having been reworked by a year and a half’s worth of wave action, the bar is now located near the shore and is accessible by foot from London Road.  Photographic and video documentation of the flood, as well as high stand debris markers, allow us to reconstruct flow conditions during this rare event. Using this documentation, field and remote measurements, and an Excel Software Plug-in we will present a reasonable measure of peak discharge needed to create the mouth bar seen today.  

            Cross sections of the river were taken using stadia rod in conjunction with a laser range finder and an eye level. Two locations were utilized, 1) on the upstream side parallel to London Road Bridge, and 2) about 150 meters up river from the bridge. Due to the cross section near the bridge being of low resolution due to our difficulties with the kayak data acquisition method it was not used in our final calculations.  
The gauging station at Amity Creek was destroyed during the flood so we used two approaches utilizing comparative analysis to find the discharge. A Post-it Note reference we gained from personal communication with Karen Gran lead us to a discharge rate of 2070 cubic feet per second (cfs) for Amity Creek. Through comparing this discharge value and Amity’s drainage area (16.5 mi2) to the watershed area of Lester River (35.6 mi2) we determined an estimated discharge rate for Lester River to be 4460 cfs, for an estimated combined flow of 6000 cfs. We also compared the total drainage area of both Lester and Amity (52.1 mi2) to the watershed size of the Knife River along with an estimated discharge as determined by the USGS for the Knife River (~25,000 cfs; Czuba et. al., 2012). With these approaches, an upper bound of 16,000 cfs was found along with a lower bound of 6000 cfs.
To measure the estimated volume of the deposited mouth bar, our study group conducted another survey. Using a stadia rod, laser range finder, and eye level, we measured a profile on the riverside adjacent to the mouth bar, a profile across the crest of the mouth bar, and a longitudinal profile over the mouth bar. It was easy to tell what clasts are associated with the reworked mouth bar and those of the lake shore due to their differing angular characteristics. Using the average river depth and average crest height we determined an estimated cross sectional area and multiplied this with the length of the mouth bar to determine an estimated volume of deposited material.
To fully determine the sediment transport rate of Lester River during the flood, we need more data. A grain size distribution was conducted using a Wolman pebble count with 116 clasts (Wolman, 1954). The surface slope of the reach from the delta to upstream survey site was determined using LiDAR and determined to be 0.007. Lastly, a Manning’s n roughness value was estimated (0.04) based on accepted values for a gravel bedded stream (Chow, 1959).
Data processing was done by BAGS (Bedload Assessment in Gravel-bedded streams; Pitlick et. al., 2009), a Microsoft Excel extension. BAGS accepts inputs of discharge rate, river profile, and grain size cumulative percentage, and outputs a bedload transport and transport capabilities. BAGS also give the height of flow needed to sustain such an inputted discharge rate for a given cross-sectional area. Additional inputs into BAGS were surface slope and an estimated Manning’s n.

            The river profile parallel to the London Road Bridge was not used in the investigation as we determined it to be of too low of a resolution. We used the collected channel geometry from 150 meters upstream of the bridge. This profile is illustrated in Figure 1 and values are shown in Table 1. Flood debris was observed in trees about 4.2 meters above baseflow.

Blue line denotes the land surface, red line denotes baseflow conditions, and the green illustrates 2012 flood level as determined by flood debris observation. Data collected in field consists of distances 0-43.4m, the rest of the points are estimated to contain the 2012 flood level with values from Google Earth.

Grain size analysis of 116 clasts from the upstream survey site revealed a D50 of 64mm, shown in Figure 2.
Figure 2- Cumulative grain size distribution of Lester River in vicinity of geometry survey using Wolman pebble count.
            Utilizing BAGS and the upper discharge bound of 16,000 cfs, a total of approximately 6,500 kg/min of sediment was found to be moving through the system.  The lower bound of 6000 cfs had approximately 1000 kg/min of sediment moving through it.  The distribution of discharge rates by clast size and discharge rate can be seen in Figure 3.
Figure 3 - Histogram of sediment discharge rate per grain size, an output of BAGS. Blue bars respresent sediment discharge rates for the calculated upper bound of 16000 cfs; Red bars represent sediment discharge rate for calculated lower bound of 6000 cfs.
            The estimated volume of the mouth bar at the time of the survey was calculated to be 1190 m­2 by,

Assuming an average density associated with sedimentary rocks of 2500 kg/m3, we can calculate time of deposition. At the calculated upper bound sediment transport rate of 6500 kg/min, the bar would take about 7.5 hours to accumulate the estimated volume.  At the lower bound sediment transport rate of 1000 kg/min, the bar would take about 45 hours to accumulate.

Figure 4 - Three dimensional surface plot of the Lester River mouth bar, assuming linear relationships. Measurements are taken with a stadia rod and eye level.
            Obtained cross-sections and photographic documentation contain many indicators of the flood suggesting a flood height of 4.2 meters.  Large point bars, large woody debris, and half-meter boulders were found throughout the study area.  
The distribution of sediment transportation rates by grain size followed the cumulative percent curve. Meaning the highest rate of sediment flux occurred with the D50 value of 64mm in both the upper and lower bound scenarios.  
In attempting to understand where the actual river discharge was in relation to our upper and lower bounds we analyzed the cross section produced by each, particularly the maximum flow depth output from BAGS which was 3.2 m at 16,000 cfs and 2.0m at 6000 cfs.  A high flood marker was found to be 4.2 meters flood water depth which points towards the upper bound being a potentially more accurate average discharge rate.  It is likely that the actual discharge was even larger than the 16,000 cfs. Using BAGS to find a corresponding flow rate to match the 4.2 meter flood height, a discharge of 18,000 cfs was found, moving 8100 kg of sediment per minute. 
            The 7.5 hour time period that it would take to deposit the measured mouth bar at the upper discharge boundary entered into BAGS is a reasonable time interval.  The river was not truly at this exact discharge rate steadily for eight hours and was likely fluctuating, but it is a good average rate. 7.5 hours is a reasonable amount of time when compared with the hydrograph of similar rivers in the area.  Lower bound inputs produced much lower sediment transport rates which were insufficient for creating a mouth bar of the observed size in a reasonable amount of time.  Therefore, the higher bound is again indicated to be closer to reality.  

            Lester River during the June 2012 flood was capable of moving clasts ranging from 8 mm to half a meter, accounting for a calculated sediment flux of 6500-8100 kg/min. Observed high flood markers from field and remote measurements suggest the max flood stage height was about 4 meters, ranging between 3.2 and 4.2 meters during peak flow. Based on our estimate volume of the mouth bar, these data suggest the material was deposited in 6-7.5 hours. We believe this number to be accurate for this time periods fits well with the hydrograph of the Knife River during this event, a similar Duluth bedrock stream.
