HydroJULES是一个由NERC资助的项目，该项目汇集了NERC中心调查，以研究如何改善模型中整个水文循环的模拟。BGS的作用是告知将地下水纳入陆地表面模型联合英国陆地环境模拟（JULES）（Best等人，2011; Clark等人，2011年）和水文模型网格到网格（例如贝尔等人，2009年）。为了促进这一文献综述已经进行了目前的方法，包括地下水在陆面模型。使用关键词“全球地下水模型”、“陆面模型”和“参数化”/“参数化”检索文献。此外，还总结了与HydroJULES相关的主要全球数据集。主要发现是LEAF-Hydro方法（Miguez-Macho等人，2007）是文献中将地下水模拟纳入陆面模型的最实用方法之一。建议针对英国现有的BGS地下水流模型对LEAF-Hydro方法进行测试。
HydroJULES is a NERC-funded project that brings together NERC Centre-Surveys to investigate how to improve the simulation of the whole hydrological cycle in models. BGS’ role is to inform the inclusion of groundwater in both the land surface model Joint UK Land Environment Simulation (JULES) (Best et al., 2011; Clark et al., 2011) and the hydrological model Grid to Grid (e.g. Bell at al, 2009). To facilitate this a literature review has been undertaken of the current methods for inclusion of groundwater in land surface models. The keywords ‘global groundwater model’, ‘land surface models’ and ‘parameterisation’/‘parameterization’ were used to search the literature. Further, the main global datasets of relevance to HydroJULES have been summarised. The main finding is that the LEAF-Hydro approach (Miguez-Macho et al., 2007) is one of the most practical methods in the literature for including groundwater simulation in a land surface model. It is recommended that the LEAF-Hydro approach should be tested against existing BGS groundwater flow models for the UK.
