Quiz 01
What is a Water Balance Equation for the Albion storm water sewer system
dS= Pr + Gi + Mu - (ET)
What is the water balance equation for the change in storage of stream water at Tim and Beth's property?
dS= (P+Gi+RO)-(ET+Go+O)
Draw a diagram with the following- interflow, discharge out, throughfall, infiltration, lateral floodplain loss, evapotranspiration, interception, return flow, precipitation, saturated overland flow, stem flow, groundwater in/out, surface detention
it wont let me add a photo.. so i'll judge it lmao
Write out a nutrient balance equation for nitrogen in wetlands
dSN= (Atm+Si+Gi)-(So+Go+Bacteria)
Draw the temperature profiles for a monomectic lake in Brazil for the months of May and December
May= colder at surface
Dec= warmer at surface
Which type of tree intercepts the largest amount of precipitation?
What are: coniferous trees
How will urbanization effect storm event hydrographs (compared to forested areas)?
The urbanized location will experience a higher peak in event flow
True/False= when antecedent moisture conditions are dry, event flow/effective precipitation tend to be a larger proportion of total rainfall.
False- dry conditions= more storage space for water in the soil, less water will be immediately added into the stream
What distinguishes a wetland from terrestrial or aquatic systems?
Dry and wet periods, may or may not be fully submerged in water, and plants resilient to both wet and dry conditions.
Also productivity is =terrestrial and >aquatic
Name 2 main differences in the epilimnion and hypolimnion of a stratified lake.
Epi= more light and oxygen
(remember hypo=low)
Would you expect more rapid infiltration near a stream or uphill?
What is: uphill, because the water has more room to infiltrate
Three tributaries of a river system have storm event water arriving at the main branch at the same time. How many peaks will the hydrograph record for this event?
what is... one
How would a hydrograph be effected by a rainfall event that lasts much longer than the time it takes for water to travel the longest flowpath to the stream (3 answers)
The rising limb would be longer, the peak would last until rainfall is over, and recession would occur slowly
Which compound is more likely to be held in wetlands instead of transport? NO3- or NH4+
NH4+ because microbes need it, plants uptake it, and it binds well to soils
True/False= Lakes and ponds have firm distinctions defined systematically based on physico-chemical attributes
False :(, it may be loosely based off of size/surface area/depth, but there are no universal criterion.
How will the infiltration rate compare to hydraulic conductivity under full saturation?
Infiltration rate will take longer
Name the stream order: when two streams converge, you add the numbers together regardless of their value.
What is Shreve
Draw a hydrograph for locations upstream and downstream of a single rainfall event
Again, no photo, but downstream should have a lower and longer peak!
How would Ferric Iron (Fe3+) react in a low-oxygen wetland layer.
It will be reduced to Fe2, and move with water transport before it is deposited in other layers.
What is the relationship between the profundal and pelagic zones?
Pelagic zone= open water
How will the infiltration rate compare to infiltration capacity when rainfall is less than capacity
Infiltration will be slower
Name the stream order: When two branches of a river system converge, you increase the order by 1 only if the branches have the same original value.
What is Strahler
What was the name of the candy joe gave us all that margo thought might be an "iowa thing"
White rabbit (half points cuz i'm mean like that)
Place these chemical compounds in order of most energy to least energy for microbes:
CO2, Fe(OH)3, MnO2, NO3, O2, SO4
If the wind is blowing to the east in the northern hemisphere, describe the net motion of water in relative directions and explain why that occurs.
Water motion is deflected to the right due to the Coriolis effect, so the water moved in a south/southeastern direction.
