  abstract = {in the semi-arid {B}razilian {N}ortheast, the exploitation of alluvial aquifers for irrigation and domestic supply to rural communities over the last 10 years has upset the traditional mechanisms of water resources management. {I}n the {F}orquilha watershed (221 km(2): 5 degrees 17 ' {S}, 39 degrees 30 ' {W}), the two main water resources are reservoirs (with a capacity exceeding 0.9-6.7 x 10(6) m(3)), used for domestic water supply only, and an alluvial aquifer (2.3 x 10(6) m(3)), used for irrigation and domestic water supply. {F}rom 1998 to 2006, the irrigated area with alluvial groundwater increased from 0 to 75 ha, and the fraction of population supplied through domestic water networks, using reservoirs and the aquifer, increased from 1% to 70%. {B}ased on physical and socioeconomic issues, three main water territories have been defined ("{A}quifer", "{R}eservoirs", and "{D}isperse {H}abitat"). {C}onsidering the next 30 years with a realistic population growth, three hypotheses regarding irrigated area (i.e., 0, 75, or 150 ha), and several possible water-management scenarios, hydrological balance models were built and used to simulate the different impacts on water resource availability and salinity. {S}imulation results showed that, in all cases, releases from the upstream main reservoir are necessary to keep reservoir salinity below 0.7 g {L}-1 and for guaranteeing domestic needs in the whole watershed. {A}s a consequence, a management approach that takes into account the interrelations among the three territories is necessary. {M}oreover, the simulations showed that the area of irrigated fields cannot exceed the current extent (75 ha), or serious restrictions on water availability and salinity will take place. {M}oreover, important socioeconomic problems are expected, including a high cost of palliative water supply with tank trucks from external sources.},
