To assist in the sustainable management of water resources, a groundwater model of the shallow groundwater in the Plaine du Nord–Massacre transboundary aquifer system was developed. The Plaine du Nord–Massacre Aquifer is one of the largest aquifer systems of Haiti, supposedly bearing a high potential for water supply and irrigation. The shallower part is already tapped by hundreds of domestic wells and hand-pumped public and private boreholes. In the framework of the AVANSE project (Appui à la Valorisation du Potentiel Agricole du Nord, pour la Sécurité Économique et Environnementale), a USAID funded project aiming at developing sustainable agriculture in the region, a groundwater model was built to assist in decision making. The finite-difference-based MARTHE software was used for the model. Due to the lack of monitoring data, the calibration of the model could only be carried out under steady-state hydraulic conditions. It should thus be considered as a first step towards a better characterisation of the aquifer’s potential. However, the model computed a groundwater balance at the scale of the aquifer showing that significant water resources can be easily mobilized if one carefully manages to rule out local operational difficulties. The simulated groundwater drawdowns using transient simulation of irrigation scenarios are pluri-metric, reaching 6–7 m. New irrigation wells must be deeper than the current average depth of wells to support agricultural development projects.

为了协助水资源的可持续管理，我们开发了 Plaine du Nord-Massacre 跨界含水层系统中浅层地下水的地下水模型。Plaine du Nord–Massacre 含水层是海地最大的含水层系统之一，据说具有很高的供水和灌溉潜力。较浅的部分已经被数百口国内井和手动泵送的公共和私人钻孔开采。在 AVANSE 项目（Appui à la Valorisation du Potentiel Agricole du Nord，pour la Sécurité Économique et Environnementale）的框架内，美国国际开发署资助的一个旨在发展该地区可持续农业的项目，建立了一个地下水模型来协助决策。该模型使用基于有限差分的 MARTHE 软件。由于缺乏监测数据，模型的校准只能在稳态水力条件下进行。因此，应将其视为更好地表征含水层潜力的第一步。然而，该模型计算了含水层规模的地下水平衡，表明如果仔细设法排除当地的运营困难，就可以轻松调动大量水资源。使用灌溉场景的瞬态模拟模拟的地下水下降是多尺度的，达到 6-7 m。新的灌溉井必须比目前的平均井深更深，以支持农业发展项目。该模型计算了含水层规模的地下水平衡，表明如果仔细设法排除当地的运营困难，就可以轻松调动大量水资源。使用灌溉场景的瞬态模拟模拟的地下水下降是多尺度的，达到 6-7 m。新的灌溉井必须比目前的平均井深更深，以支持农业发展项目。该模型计算了含水层规模的地下水平衡，表明如果仔细设法排除当地的运营困难，就可以轻松调动大量水资源。使用灌溉场景的瞬态模拟模拟的地下水下降是多尺度的，达到 6-7 m。新的灌溉井必须比目前的平均井深更深，以支持农业发展项目。
