Resumen
Understanding the hydrology of the páramos is of vital importance, since they are
responsible for regulating hydrological processes and guaranteeing water supply
for the population. Because of this, several hydrological modeling studies have
been carried out in Ecuador, however, they have focused on southern páramo
areas of the country. The present project focuses on the study of two páramo
micro-catchments in northern Ecuador that are part of the Jatunhuaycu
Hydrographic Unit (UHJ). In order to conceptualize their hydrological processes, a
rainfall-runoff modeling approach based on multiple hypotheses was developed.
Two- and three-reservoir models were tested in parallel for the above-mentioned
micro-catchments, which have already yielded satisfactory results in other paramo
areas. Interestingly, although the micro-catchments are located in the same
hydrographic unit next to each other, different runoff coefficients (EC) were
obtained for each one (0.08 and 0.41). In general, it was observed that the model
with three reservoirs in parallel had a better performance; however, in the microcatchments with the lowest EC, a water loss due to deep infiltration had to be
included to make it possible to simulate the flow at its outlet. In conclusion, this
thesis points out the possibility of finding important differences between nearby
micro-catchments and the importance of flows in all soil layers to maintain the
dynamics in their flows. This can help decision makers to be clear about the
importance of the soils in these catchments, as well as to consider the differences
that can be found in these catchments. So that constant monitoring is necessary
for their proper management
