水文过程的第二个年度评论问题的介绍试图把收集的论文优惠流量和旅行时间分布到一个更一般的背景下测试模型的假设流域系统如何运作。有人建议，由于数据和模型中存在非平稳和认识错误的可能性，这种检验可以在拒绝主义的可接受性限度框架内进行。在这些特定的研究领域的假设检验的原则和困难进行了讨论。从这一讨论中得出的一个重要观点是，使用正式的测试框架，以及在考虑到数据中的不确定性后拒绝模型作为假设，是开发更好的理论和数据集的起点。版权所有© 2010约翰威利父子有限公司.
This introduction to the second annual review issue of Hydrological Processes tries to put the collection of papers on preferential flows and travel time distributions into a more general context of testing models as hypotheses about how catchment systems function. It is suggested that, because of the possibilities of non‐stationary and epistemic errors in both data and models, such tests could be carried out within a rejectionist limits‐of‐acceptability framework. The principles and difficulties of hypothesis testing within these particular research areas are discussed. An important point to take from this discussion is that the use of a formal testing framework, and the consequent rejection of models as hypotheses after allowing for uncertainties in the data, is the starting point for developing better theories and data sets.
