抽象的。无资料流域的一个主要研究挑战是快速评估流域的主要水文过程。在本文中，我们提出了一个自上而下的方法，从第一场侦察感知模型的发展，模型概念化，评估，拒绝，并最终，一个更实质性的实地活动，建立在初始建模。这种方法使我们从一个初始状态，很少有人知道集水区的水文过程，包括初步确定水源和评估我们的采样设计的有效性，对一个更完整的看法行为。
Abstract. A major research challenge in ungauged basins is to quickly assess the dominant hydrological processes of watersheds. In this paper we present a top-down approach from first field reconnaissance to perceptual model development, model conceptualization, evaluation, rejection and eventually, to a more substantial field campaign to build upon the initial modeling. This approach led us from an initial state where very little was known about catchment behavior towards a more complete view of catchment hydrological processes, including the preliminary identification of water sources and an assessment of the effectiveness of our sampling design.
