Introduction
unconsolidated sediments deposited at the base of hill-slopes
by either rainwash, sheetwash, slow continuous downslope
creep, or a combination of these processes; (2) present day
and fossil valleys, principally two main river systems, Oued
Oum Er-Rbia and Oued Tensift, and several smaller and
secondary rivers; and (3) the Plio-Quaternary dunes com-
plex, with regular dune morphology separated by inter-dune
depressions, the dune ridges extending over large distances
with a SSW trend (Aboumaria
1993
).
The coastal area consists of four geomorphological ele-
ments: (1) the beaches, which are quite commonly rocky,
especially in the south-western part of the region, and sandy
in the north-eastern part; (2) the Plio-Quaternary consolidated
dunes complex, which is aligned sub-parallel to the present
Doukkala-Abda region, study area, is located in the north-
western part of central Morocco, bordering the Atlantic coast
at the crossroads between three of Morocco
'
s main tourist
destinations
Casablanca, Marrakech, and Agadir. It covers
an area of approximately 14,285 km

and incorporates four
provinces, El Jadida, Sidi Bennour, Sa

). The population of the region is 4,284,039 inhabit-
ants. Geographically, the region consists of two main zones:
the coastal zone and the hinterland. The latter, which cor-
responds to the Doukkala-Abda plain, is characterized by
three geomorphological features: (1) base of slope colluvial
deposits, described by Gigout
