本文提供了一种概念性的方法来探索泛滥平原作为完全耦合的人-水系统的复杂动力学。一些水文学家最近调查了人类活动(如防洪措施、土地利用变化和聚落模式)对洪水频率和严重程度的影响。与此同时，社会科学家展示了三角洲和泛滥平原地区的社会和水之间的相互作用，包括洪水的频率和严重程度，如何影响社会关系展开的方式(在治理进程、政策和机构方面)以及社会组织(在空间、政治和社会方面)。然而，我们认为，水文和社会过程之间的相互作用和相关的反馈机制在很大程度上仍然没有被探索和了解。因此，需要更好地了解机构和治理进程如何与三角洲和泛滥平原的水文进程相互作用，以影响洪水的频率和严重程度，同时(反过来)水文进程共同构成社会领域，并对社会关系如何展开以塑造治理进程和机构产生影响。因此，我们的研究目标不是确定循环的一方或另一方(水文或社会)，而是解释它们之间的关系：它们如何、何时、何地和为什么相互作用，以及对社会关系和水文过程都会产生什么结果？我们认为，长时间序列的水文和社会数据，以及遥感数据，可以用来从非常规方法观察洪泛区的动态，并了解在不同的水文气候条件、社会文化背景和治理模式下，洪泛区发生的水与人类系统之间复杂的相互作用，涉及人类影响的规模和程度。
This paper offers a conceptual approach to explore the complex dynamics of floodplains as fully coupled human-water systems. A number of hydrologists have recently investigated the impact of human activities (such as flood control measures, land-use changes, and settlement patterns) on the frequency and severity of floods. Meanwhile, social scientists have shown how interactions between society and waters in deltas and floodplain areas, including the frequency and severity of floods, have an impact on the ways in which social relations unfold (in terms of governance processes, policies, and institutions) and societies are organised (spatially, politically, and socially). However, we argue that the interactions and associated feedback mechanisms between hydrological and social processes remain largely unexplored and poorly understood. Thus, there is a need to better understand how the institutions and governance processes interact with hydrological processes in deltas and floodplains to influence the frequency and severity of floods, while (in turn) hydrological processes co-constitute the social realm and make a difference for how social relations unfold to shape governance processes and institutions. Our research goal, therefore, is not in identifying one or the other side of the cycle (hydrological or social), but in explaining the relationship between them: how, when, where, and why they interact, and to what result for both social relations and hydrological processes? We argue that long time series of hydrological and social data, along with remote sensing data, can be used to observe floodplain dynamics from unconventional approaches, and understand the complex interactions between water and human systems taking place in floodplain areas, across scales and levels of human impacts, and within different hydro-climatic conditions, socio-cultural settings, and modes of governance.
