There are a growing number of hydrologic models with fully 2D and 3D formulations that seek to combine surface and subsurface flow. These complex models fall into two broad categories: integrated and coupled, with about ten of these models available. Additionally, many of these models are coupled to land-surface energy balances, biogeochemical and ecological process models and to atmospheric models. While there is an increasing need and application for large scale, complex models of environmental function for hydrologic prediction and environmental understanding, no formal verification and/or benchmarking of these models has been performed. This workshop will gather many of the authors of these coupled, integrated environmental models for a first-of-a-kind model intercomparison. The workshop will perform a suite of benchmarking problems with each model and will run a series of idealized problems that emphasize and identify various model components and interactions. The benchmarking problems can then be used in subsequent future benchmarking intercomparison exercises and will be provided freely to anyone in the hydrologic community. This intercomparison will be published in a peer reviewed journal.

越来越多的水文模型采用完全2D和3D的公式，试图将地表和地下水流结合起来。这些复杂的模型分为两大类：集成的和耦合的，大约有10个这样的模型可用。此外，其中许多模式与陆地表面能量平衡、生物地球化学和生态过程模式以及大气模式相耦合。虽然对水文预测和环境理解的大规模复杂环境功能模型的需求和应用日益增加，但尚未对这些模型进行正式验证和/或基准测试。本次研讨会将聚集许多这些耦合的、综合的环境模型的作者，进行首次的模型相互比较。研讨会将对每个模型执行一套基准问题，并将运行一系列理想化的问题，这些问题强调并确定各种模型组件和交互。然后，基准问题可用于今后的基准相互比较工作，并将免费提供给水文界的任何人。这一相互比较将发表在同行评议的期刊上。
