what relationship is rainfall run off to overland and what are
the factors that plays an important role in this aspects of
hydrology?
How does rainfall run off contribute and affect overland
flow?
How does different type of soil affect both confined and
unconfined aquifer and which soil type works best for each aquifer
and reason ? and how does their permeability characteristics
contribute to that.
What is the relationship between porosity and permeability
and hydraulic conductivity as well as Discharge for both
unconfined and confined aquifer? How does decreasing/ increasing of
any of this variables affect the other in both aquifers(
confined and unconfined).
Overall how is rainfall run off and Overland and both (confined
and unconfined aquifer ) contribute to the hydrological cycle?
