Previous studies have highlighted the importance of natural environmental conditions on the development of ancient societies. Besides prominent natural disasters, adaptation of societal and economics strategies might even origin from subtle and less dramatic changes such as natural river dynamics. However, the individual impact and its spatial and temporal dimensions need to be investigated in each particular region. The aim of this project is to enlighten the interaction between fluvial dynamics and the response of local societies in the area of the Nan River system, northern Thailand. Our hypothesis is that the natural dynamics of the Nan River had a major effect on the settlement strategies in the region. In the meandering fluvial landscape, the channels of the Nan River shifted towards and away from settlements, which led to problems with either flooding or the cut-off from water supply and the most important transport paths. The approach of this study is to use remote sensing in combination with fieldwork to decipher past configurations of the river network. Once suitable locations have been identified, fluvial sediments will be sampled in natural outcrops, hand-excavated ditches, and in drill-cores. Sediment taken from the exposures will be used to characterise and date with the aim to reconstruct the geometry of the river network at different times. These reconstructions will be cross-checked with ancient documents for deciphering the likely interaction between natural river dynamics and human response. Due to the wealth of written documents and archaeological sites, we will concentrate on the Lanna and Sukhothai periods (800-200 years ago).

以往的研究强调了自然环境条件对古代社会发展的重要性。除了突出的自然灾害外，社会和经济战略的调整甚至可能源于微妙和不太剧烈的变化，如自然河流动态。然而，需要在每个特定区域调查个别影响及其空间和时间方面。该项目的目的是启发河流动力学和当地社会的反应之间的相互作用，在泰国北方的南河系统的区域。我们的假设是，南河的自然动态对该地区的定居策略产生了重大影响。在蜿蜒的河流景观中，南河的河道向定居点和远离定居点移动，这导致了洪水或供水中断和最重要的运输路径的问题。本研究的方法是利用遥感结合野外工作来破译过去的河流网络的配置。一旦确定了合适的地点，将在天然露头、人工开挖的沟渠和岩心中对河流沉积物进行取样。从暴露中提取的沉积物将用于测量和日期，目的是重建不同时间的河流网络的几何形状。这些重建将与古代文献进行交叉检查，以破译自然河流动力学和人类反应之间可能的相互作用。由于丰富的书面文件和考古遗址，我们将集中在兰纳和素可泰时期（800-200年前）。
