ABSTRACT: This study aims to compare
the performance of two hydrological models, conceptual (HEC-HMS) and spatial
(ATHYS) on the Aguibat Ezziar watershed. The comparative analysis is based on
the performances of simulation in terms of Nash-Sutcliffe and RSR. The study
requires the collection of a series of data as inputs models namely rainfall
data, water quantity, soil occupation, DTM and requires also a calibration in
order to evaluate these models in validation phase. The simulation results were
obtained from the validation phase aiming to replicate the operation of
watershed Aguibat Ezziar, and present a suitable adjustment perspective of the
observed hydrograph. These results show that the objective is achieved and a
model distributed like ATHYS plays an effective role to improve the efficiency
and present a high advantage in anticipation of runoff volume comparing with
other models.
