Wonders of Winter: Solid water (UPDATE)

After last post Wonders of Winters here an update:

Temperature increased and the solid state became liquid. All snow puppets and snow on the roofs disappeared leaving behind an ordinary world of green and brown. Finally runoff again <:D <:D <:D

Wonders of Winter: Solid water

 


For a summer hydrologist winter is the "borring" time. Depending on the catchment location precipitation is solid and the catchment is in deep winter sleep without any reaction with only some liters of base flow. zzzz zzzz zzz 
Warm inside with a warm cup of coffee and x-mas sweets its nice to work on last seasons field data and see what happened. While working and thinking some times the falling snow flakes divert the attention and makes one wonder. Not only the light isotopic values of precipitation but even more: the self organizing abilities of water. So looking outside the office window one sees a former cage from the ecology section where snow build a dome shape structure on top of the fine mesh of the fence without falling down on top of the building below. Still wondering how this is possible... Any clue?



Fig 1. Look down to the former cage. In orange a grid made from beams and a smaller fence in between in green.
Fig. Different perspective to show the snow cover thickness.






Fig. 3 Schematic view with top view of the fence. View a-a shows the distance of the fence grid and the building of the dome shape structure of snow.

Replacement for the Grannystandard...


The Granny-standard,a golden rule whether one is capable in his/her field to reduce his/her knowledge and explain what one is doing, that even a Grandma understands. Major critic to this standard is the fact that a Grandma is positively biased toward the grandchild.

A better standard would be the UC-12 Standard ( UC-12: unknown child of 12 years with interest in gadget's and high tech social network related things). One should explain what one is doing for profession, to a group of unknown children with age of 12-13 years. Due to the fact that there is no family relation (its unbiased) and if the level is too high and without entertainment, they lose the interest and its boring. First test of the UC-12 Standard was the Tag der Forschung 2012 (Day of Science).



Tag der Forschung 2012 - Infiltration comparison between sand and gravel








Tag der Forschung 2012 - Explaining Groundwater wit the sandbox model


Tag der Forschung 2012 - Tracer test in Sandbox

update:

How would you make kids enthusiastic about process hydrology, groundwater and precipitation where one gets wet...?

Some hydro-medicine

Hat-sjuuu
Haaattt-sjuuuu

The thermometer was rising and not because of the cool autumn temperature. Nope its THE nightmare of PhD-students caused by some small viruses. It keeps you in bed and @ home for some days. Although its a nuisance, once the brain is functioning again, its a good moment to reflect, rethink and read papers for which one never has time for.

The following medicine prescription cures and helps hydrologist to get better soon. 
Click 2 links every day and drink lots of H2O for five consecutive days and everything is fine. 
Danger to many links can cause an allergic reaction. 

Note these links are not meant as substitution for a professional doctor and one should always take first professional advice.

Run or not to run...

 There was a running water during the SOLA 2012 where parts of H2K participated and achieved a quite good result .
Sola 2012, Runnig water logo of the H2K-team

Running through the water on the other hand was recently in the head lines.
The publication Whether or not to run in the rain (Bocci 2012) had a broad international media attention and discussed what we should do when it starts to rain.Its interesting that a physicist brought up this topic. He described the phenomenon in an elegant way. However one shouldn't run but just dress in a proper way and stand still during this most interesting play of nature. Enjoy when stream starts to respond and see the forces of nature. Measure sample or what ever but enjoy the hydrology not just run!!!






Several international media told us what to do in rain but forgot the most important...

Mythen...

The Alptal - Zwäckentobel is not only playground for hydrologist but serves as well as a scenic background for some nice hydrotunes, press play and Njoy ... ;)

Climate change CH...

The climate changed and will change. We scientist look in the glass marble use models etc to understand the recent and forecast the future.
The Alptal has an above CH average amount of precipitation. This amount of water dilute what ever is solved in the water. This summer season 2012 is rather mild, has an below average monthly precipitation input and streams are in a low flow regime. Last three years I visited the Alptal regularly but never saw up to now algae in the water! Will be this the biggest problem in CH with the changing climate: water quality?

Next type of Phd-student - field hydrologist?


A small step for Curiosity but ... After a cool touchdown curiosity is driving around on mars looking for life + H2O and sending some nice pics. All nice but I can imagine in 10 years PhD students can remain seated in the office sending commands to a rover exploring interesting features with a mobile iso-chem lab, discharge - evaporation - stem flow measurements. 

But luckily down on earth we can still go to the field catch some fresh air, be curious and get wet <:D

Hey mister snowman...

Welcome back. After weeks of snow melt, today mister snowman came back. With some nice fresh powder.
This shows the interesting part of alpine catchment research. The field season starts in June to September in which the data has to be collected.

030512 Start F3

030512 Start of Field season #3 

After a long winter, which started +/- September 2011, our catchment is still white colored.The lower parts of the Alptal are snow free but after AT 8 the snow cover closes again up to 1m in thickness!! We reinstalled the Gauges and repaired the winter damage and hope for a good F3.

Is it a bird? It's a ... cool toy for hydro - remotesensing

R-Pod is a project of imaging robot dedicated to geomatic applications. It consists of hardware developed by senseFly, an EPFL spin-off (micromechanics) and software developed by Pix4D, also an EPFL spin-off (Computer Vision). Both components were reliable and flexible enough, two conditions needed in order to optimize the workflow for photogrammetric and remote sensing applications. During the demonstration, the concept and the mission preparation will be shown, and then the flight will be carried out, weather depending. A new, simple FCIR camera will be used over the Irchel Park at a flying height of 150 m. Finally, first results will be displayed and commented and the complete workflow will be explained. The whole demonstration should last about an hour, the duration of a typical punctual mission, in time and in space. This should lead to a
discussion about “Kleenex” geodata, easy to acquire, very useful, yet rapidly obsolete.(From RSL Flyer)    For demo play VDO below

'Faster than the speed of light'

CERN scientists 'break the speed of light' 


Scientists said on Thursday they recorded particles travelling faster than light - a finding that could overturn one of Einstein's fundamental laws of the universe. (telegraph.co.uk)

If it does not, one of the pillars of modern science may come tumbling down.

Cern UPDATE 23 February 2012

The OPERA collaboration has informed its funding agencies and host laboratories that it has identified two possible effects that could have an influence on its neutrino timing measurement. These both require further tests with a short pulsed beam. If confirmed, one would increase the size of the measured effect, the other would diminish it. The first possible effect concerns an oscillator used to provide the time stamps for GPS synchronizations. It could have led to an overestimate of the neutrino's time of flight. The second concerns the optical fibre connector that brings the external GPS signal to the OPERA master clock, which may not have been functioning correctly when the measurements were taken. If this is the case, it could have led to an underestimate of the time of flight of the neutrinos. The potential extent of these two effects is being studied by the OPERA collaboration. New measurements with short pulsed beams are scheduled for May. (Cern)


So we Einstein was wrong? A problem with our conceptual model of the Universe or just a software problem or cable connection like we face some time in hydrology  see Hydrologist vs. nature ... PART III

Trek4Education -> Support Paribesh on his 1700 km






A Forest Gump on his trip through the Himalaya needs support check this: http://trek4education.org/donate/

The Great Himalaya Trail (GHT) is a first of its kind trail in Nepal that unifies all the separate trekking routes into one route, traversing east to west of the country. The GHT will pass through the most remote parts of Nepal across the rugged mountains and valleys. It will encompass the entire length of the country passing though the world’s most famous mountain ranges including Mt. Everest, Kanchenjunga, Annapurna, Makalu Barun, Ganesh Himal and Dhaulagiri.
Traveling in such untrodden trails of the GHT offers exceptional opportunities to embrace the serene tranquility of nature and witness what has rarely been seen before. On the trail, one can observe mountain communities living amidst climate vulnerabilities and disaster risks and also witness climate resilient adaptation practices they have adopted. Undoubtedly, the impacts of climate change have left both the communities and the environment exposed towards an uncertain future.
This project intends to map these changes in the form of narrative writings, photo essays, stories and interviews. These expressions will be compiled in a climate travelogue that will provide meaningful information about the lives of the mountain communities, their struggle with climate change impacts, and will give a real sense of changing climate scenarios in the Himalayas. Such a view of climate change impacts is critical to supplement scientific knowledge and move forward our discussion on climate change adaptation strategies.
In short, the primary objective of this project is to develop a ‘Climatologue’ (a climate travelogue) accounting the impacts of climate change, its related physical and social vulnerabilities, along with sustainable adaptation practices along the stretches of the GHT. This book will be based on science, local knowledge, and my personal observations. The documentation process would entail written analysis of field-based observations, personal narrations supplemented by photo essays, interviews, climate impact stories and case studies.
