The Budyko framework allows estimation of actual evapotranspiration based on the balance between the supply of water and energy (they are usually represented by precipitation and potential evaporation). It is a steady state model and has been widely used to examine the terrestrial water budget at decadal and catchment scales. For its simplicity, the model is extremely powerful with model performance similar to that of complex hydrological models (when applied at the appropriate scales).
“Drinkwater raakt op: rivieren straks te vuil om nog te zuiveren” kopte de Telegraaf op de voorpagina op woensdag 3 oktober naar aanleiding van het RIVM/Deltares rapport over de effecten van klimaatverandering op de waterkwaliteit bij innamepunten voor drinkwater. Vier Delftse onderzoekers (TU Delft en UNESCO-IHE) menen dat het zo’n vaart niet zal lopen. Het rapport houdt volgens hen te weinig rekening met de héle watercyclus en met de Nederlandse innovatiekracht op het gebied van drinkwater- en afvalwaterzuivering. Wij hebben in Nederland het beste kraanwater ter wereld, ook nog in 2050.

(often occurring problem with TUD-installation)
When using the build mode ‘Latex=>PS=>PDF’ and there is no PDF generated, but there is a .DVI-file and a .PS-file generated, TeXnicCenter is not able to convert a PS-file to a PDF-file. Likely, your build-settings are wrong.
- Go to tab BUILD, then DEFINE OUTPUT PROFILES and select the profile “LaTeX=>PS=>PDF”.
- Go to tab POSTPROCESSOR and click “Ghostscript (ps2pdf). In the Executable line write the location of ghostscript (e.g. C:\Program Files\GS\gs8.64\bin\gswin32c.exe). [if Ghostscript is not installed, first install it :)]
An annoying bug: when you have JabRef open and then start TeXnicCenter and try to run your code with a reference to your JabRef-database, TeXnicCenter crashes. I did not find any solution for it, but at least it helps to first open TeXnicCenter and then open JabRef. Don’t ask me why, but it often helps.
According to the bug-report it has to do with the link to your bib-file: http://sourceforge.net/tracker/?func=detail&aid=3042060&group_id=36323&atid=416430
For the course “Measuring for water” (part of the minor “De Delta Denker“) thirty 3rd year Bachelor students had to develop their own sensor to measure something related to water. They used Arduino to control and process the data from the sensors. After one day getting acquainted with Arduino the students started to think about their own sensor. After three days of developing, constructing, and testing they came up with a wide variety of instruments. Tipping buckets, psychrometers to measure humidity, turbidity sensors, salt concentration meters, discharge meters, water level meters, were all developed in a short period of time. Below a short photo impression of the sensors.
