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

8.25

24.75

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

beta_n = (mean(simulated) - mean(observed))/standard deviation(observed)

NSE = 2*alpha*r-alpha²-Beta_n² (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?

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
