在回顾越南河内市地区第四纪沉积构造的基础上，建立了一个1995 - 2004年的确定性三维数值地下水流动模型。沉积结构是在32次钻探的数据基础上构建的，这些数据覆盖了整个第四纪序列（但沉积学细节很少），以及水文和水文地质数据。对稳态和瞬态条件进行了测试。模型的计算结果似乎表明，所采用的概念假设对于所模拟的领域和时期是合理的。模拟可以计算区域地下水流动趋势。它还用于评估河内浅层含水层系统的各种补给来源的相对重要性，并用于估计地下水与红河之间的相互作用。
On the basis of a review of the Quaternary sedimentary architecture in the area of Hanoi city (Vietnam), a numerical, deterministic and three-dimensional groundwater flow model has been built for a simulation between 1995 and 2004. The sedimentary architecture has been constructed on the basis of the data from 32 drillings covering the entire Quaternary sequence (but with little sedimentological detail), as well as hydrographical and hydrogeological data. Both steady- and transient-state conditions were tested. Results calculated by the model seem to indicate that the conceptual hypotheses adopted are reasonable for the modelled domain and period. The simulation allows for calculation of the regional groundwater flow trends. It is also used for assessing the relative importance of the various recharge sources of the shallow aquifer system in Hanoi, and for estimating the interactions between groundwater and the Red River.
