How much snow will be melted after 3 days of 4 degrees C? (T0 is 1 degree C, settled snow (ρ = 250kg/m3) , daily melt M=a(T-T0), a=11*ρsnow /ρwater )
2.75
11
8.25
24.75
33
If there would be fresh snow instead of settled snow, how would the answer to the previous question change?
It would stay the same
It would be lower, because the density of fresh snow is lower
It would be higher, because the density of fresh snow is higher
It would be higher, because the density of fresh snow is lower
It would be lower, because the density of fresh snow is higher
What is the difference between IWRM and sociohydrology? (multiple correct answers)
Sociohydrology includes humans, while IWRM does not
Sociohydrology is just a new name for IWRM
Sociohydrology includes feedback mechanisms between humans and water, while IWRM is a more linear approach
Sociohydrology includes ecological systems, which are not represented in IWRM
Sociohydrology can be seen as the science underlying IWRM
What is important for modeling a hydrological system?
The chosen model
The chosen model and input parameters
The chosen model, input parameters and calibration
Input parameters, calibration and experience of the modeller
All of the above
When is a model considered a good model?
This is subjective and based on the purpose of the model and choices of the modeller
When it has a NSE > 0.6
When it is verifiable
When it is validated
When it is calibrated
What is an attribution study (in meteorology)?
A study to find out if an extreme event is caused by climate change
A study to find out how likely the occurance of an extreme event is
A study to find out if (change of) probability of extreme events can be linked to climate change
A study that links extreme events to hydrological impacts
All of the above
What are the KGE and NSE of this simulation using the following formulas:
alpha = ratio between simulated and observed standard deviation
beta = ratio between simulated and observed mean
betan = (mean(simulated) - mean(observed))/standard deviation(observed)
NSE = 2*alpha*r-alpha2-Betan2 (r = correlation)
ED = sqrt((r-1)2+(alpha-1)2+(beta-1)2) (r = correlation)
KGE = 1-ED
KGE = 0.67, NSE = -1,1
KGE = 0.33, NSE = -1,1
KGE = 0.67, NSE = 0.18
KGE = 0.33, NSE = 0.18
NSE is larger than KGE
What is shown in this graph?
The budyko curve
The relation between evaporation and soil moisture
The drainage part of the soil moisture loss function
The evapotranspiration part of the soil moisture loss function
The total soil moisture loss function
What is true for the part of the graph on the left of the dashed line? (multiple correct answers)
Arid
Humid
Energy limited
Water limited
ET(act) = ET(pot) (approximately)
Can the magnitude of a missing water balance term be estimated using the Budyko curve?
No
Yes, without changing anything
Yes, but the x-axis should be changed
Yes, but the y-axis should be adapted
What happens first when flooding in a lowland area occurs
Groundwater rise
Surface runoff
Ponding
Soil moisture rise
Backwater feedback
