  abstract = {{A} {D}ecision {S}upport {S}ystem has been set up as the result of a fruitful cooperation between several public and research institutions in the framework of a large cooperation program. {T}he {DSS} aims to compare spatially and temporally sectorial water demands of the {H}aouz-{M}ejjate plain ({M}orocco) in regard to available surface and groundwater resources. {I}t is composed of a tool for satellite estimation of {A}gricultural {W}ater {D}emand ({SAMIR}), a tool for integrated water resources planning ({WEAP}) and a groundwater model ({MODFLOW}) each of them relying on a common {G}eographical {I}nformation {S}ystem not described here. {T}he {DSS} is operating on a monthly time scale. {A}gricultural water demand accounts for about 80 % of the total demand. {I}n areas where groundwater abstraction is difficult to quantify by direct methods, multitemporal remote sensing associated to the {FAO} methodology is a simple and efficient alternative to estimate {E}vapotranspiration ({ET}). {I}n this work, a monthly estimate of {ET} from irrigated areas is derived from freely available {MODIS} {NDVI} for the 2001-2009 period. {A}n important part of the paper deals with the validation of these estimates with eddy covariance flux measurements installed on different irrigated crops of the region. {R}esults are satisfactory with a minus 6.5 % error per year on the monthly time scale. {T}his preprocessing allows to dichotomize irrigated versus non-irrigated areas, and then, to estimate groundwater abstraction in subareas distinguishing by their operating modes: traditional, dam or privately irrigated. {A} dynamic linkage between {MODFLOW} and {WEAP} transfers the results of one model as input data to the other. {T}he model restitutes both spatial and temporal variations in head charges and allows the calculation of the ground water balance. {A}fter calibration, piezometric validation is acceptable for the majority of the 21 head control points.},
