Merry X-mas and happy 2016!!!

from times when there was snow

Instead from webcam in the Alptal 24.12.2015 with little snow

Happy when it rains... in the news ...

Now it finnaly rains the news is full of rainy articles check e.g. NZZ  based largly on Barnett's book Rain:a natural and cultural history  

Happy when it rains ...

After a really really long dry spell, where streams run dry and low flows got quite some media attention (see droughtCH or BAFU), today finally today some rain <:D <:D <:D

Rietholzbach Bubble-type pneumatic gauge

Instead of the usual turbulent flow with lots of air bubbles. Due to the long dry spell the water levels and flow are low with laminar flow. The laminar flow at the catchment outlet of the Rietholzbach revealed an uncommon (in the wireless data transmission and piezo-pressure age) type of water level gauge: the bubbles of the bubble-type pneumatic gauge. Press play and enjoy the relaxing bubbles :)

Theory

Air bubbler An air bubbler system uses a tube with an opening below the surface of the liquid level. A fixed flow of air is passed through the tube. Pressure in the tube is proportional to the depth (and density) of the liquid over the outlet of the tube. Air bubbler systems contain no moving parts, making them suitable for measuring the level of sewage, drainage water, sewage sludge, night soil, or water with large quantities of suspended solids. The only part of the sensor that contacts the liquid is a bubble tube which is chemically compatible with the material whose level is to be measured. Since the point of measurement has no electrical components, the technique is a good choice for classified “Hazardous Areas”. The control portion of the system can be located safely away, with the pneumatic plumbing isolating the hazardous from the safe area. Air bubbler systems are a good choice for open tanks at atmospheric pressure and can be built so that high-pressure air is routed through a bypass valve to dislodge solids that may clog the bubble tube. The technique is inherently “self-cleaning”. It is highly recommended for liquid level measurement applications where ultrasonic, float or microwave techniques have proved undependable.

Storage and flow of water in soil

Springtime, flood time ...

Like every spring the groundwater reservoirs are filled and higher up patches of snow (extra storage) which is melting away. The saturated areas are nicely colored brown.

While there are potential risk in the mountainous areas the wet state plus this weekends high precipitation causing so far only in the west flooding...
