abstract = "Conceptual large-scale distributed hydrological models (e.g.
MHD-INPE) were developed to not only be used with limited
available data but also to match the scale of atmospheric models.
However, it is unknown if it can be representative for small
watersheds in rural mountainous regions, which are crucial not
only for agriculture, but also for water supply for several uses.
Therefore, the objective of this study is to assess MHD-INPE
performance in a headwater catchment with complex terrain
alongside to a distributed physically based model (DHSVM). The
Lavrinha Watershed (LW) has a drainage area of 6.7 km2, being 63%
of the catchment occupied by native vegetation (Atlantic
Rainforest), while the remaining area is mainly occupied by
pasture for livestock farming. MHD-INPE and DHSVM were applied
using a soil moisture zone map derived from the height above the
nearest drainage (HAND) algorithm. The runoff simulated by the
MHD-INPE better fits the observed data, with a validation
Nash-Sutcliffe efficiency (NSE) of 0.70 for the daily scale,
compared to a 0.55 in DHSVM. In the evapotranspiration simulation,
both models showed similar trends, being 49% of the precipitation
in the MHD-INPE and 46% in the DHSVM, while the observed value was
49%. For the baseflow, the MHD-INPE fitted better to the observed
streamflow, whereas the DHSVM underestimated it during the dry
season. Thus MHD-INPE was able to accurately simulate the
streamflow in a mountainous headwater catchment in southeast
Brazil, despite its large spatial scale.",
