| Abstract: | In this paper the process to implement the Soil and Water Assessment Tool (SWAT) in
Catamayo-Chira binational basin (11 910.74 Km2) placed in the border area between
Ecuador and Peru (South America) is detailed. The basin under study has a low density
of meteorological and hydrological stations, as well as a notable variation in its
biophysical characteristics, which further highlights the lack of information. The SWAT
model requires a great amount of parameters for its implementation. So, we intended to
study its performance although having scarce information. In the present study, the
SWAT model made a relatively satisfactory reproduction of the historical record of
flows (EF=0.73) with certain limitations in calculation of sediment production. Two
land use scenarios were analyzed, observing that an increase of natural forest and shrubs
areas could significantly reduce sediment production. |
