“…Indeed, the disconformity can be traced across the entire Tonlé Sap lake, with the facies above this surface characterised by parallel-bedded sediments that contain individual point reflectors (Table 1; labelled 'p' in Figures 2 and 3B). These point reflectors likely represent siderite concretions (Pottier et al, 2012) or accumulations of the Asiatic clam Corbicula fluminaea (Penny, 2006) that are commonly found in the upper layer of the Tonlé Sap lake sediments. If the thickness of the parallel reflectors in Facies 3 that are truncated by the erosion surface are examined (Figure 2, inset X), it is evident that erosion of c. 1.2 m of lacustrine sediment must have taken place before the resumption of lacustrine sedimentation in Facies 4, a key point that is returned to below.…”

“…Sedimentation in Tonlé Sap lake due to sediment suspension settling, but after a period of widespread erosion that generated the extensive erosion surface that separates PES Facies 3 and 4 across all of the Tonlé Sap lake. Parabolic point reflections generated from diagenetic siderite concretions, of siderite and manganese (Pottier et al, 2012),, or accumulations of the clam Corbicula fluminaea (Penny, 2006) within the sediments.…”

We provide evidence for a large-scale geomorphic event in Cambodia's great lake, the Tonlé Sap, during the middle Holocene. The present-day hydrology of the basin is dominated by an annual flood pulse where water from the Mekong River raises the lake level by c. 8m during the monsoon season.We present new subsurface geophysical data, allied to new and past core studies, which unequivocally show a period of major mid-Holocene erosion across the entire Tonlé Sap basin that is coincident with establishment of the lake's flood pulse. We argue that this widespread erosion, which removed at least 1.2 m of sediment across the lake's extent, was triggered by up to three, likely interacting, processes: (1) base-level lowering due to mid-Holocene sea-level fall, leading to (2) capture of the Tonlé Sap drainage by the Mekong River, and (3) a drying climate that also reduced lake level.Longer-term landscape evolution was thus punctuated by a rapid, river capture-and base-level fallinduced, lake drainage that established the ecosystem that flourishes today. The scale of change induced by this mid-Holocene river capture event demonstrates the susceptibility of the Tonlé Sap to ongoing changes in local base-level and hydrology induced by anthropogenic activity, such as damming and sand mining, within the Mekong River Basin.

This article is an overview of the work that has been conducted so far on river usage and nautical technology in the history of Angkor, and a discussion on how maritime approaches can contribute to the creation of new knowledge by opening new lines of research that can help us reconstruct a more nuanced view of Angkor’s fluvial history. Although Angkor’s connection to the river network was made in the early 20th century, the compartmentalized studies that have been carried out so far on the subject of Angkor’s relationship to its watery environment have resulted in interpretations that do not reflect the complexity of the subject. It will be argued here that archaeologists who do not integrate maritime approaches in studies of cultures like Angkor, where waterways play an important role in their environment, are likely to miss important aspects of fluvial cultures. By applying concepts such as the Maritime Cultural Landscape, it will be possible to push beyond the boundaries of terrestrial approaches and discover how the environmental conditions of cultures like Angkor – with river networks as the main means of communication – resulted in the development of specific cognitive and functional traits that gave form to fluvial cultural landscapes. An example of such an approach is offered as a conclusion in an analysis of masonry bridges in Angkor’s transport network.ជាទិដ្ឋភាពរួមនៃការងារស្រាវជ្រាវដែលបានធ្វើកន្លងមក ស្តីពីការប្រើប្រាស់ទន្លេ និងបច្ចេកវិទ្យាផ្លូវទឹក ក្នុងប្រវត្តិសាស្ត្ររាជធានីអង្គរ ហើយជាការជជែកថាតើមធ្យោបាយផ្លូវសមុទ្រអាចរួមចំណែកដល់ការបង្កើតចំណេះដឹងថ្មី តាមរយៈការបើកខ្សែស្រាវជ្រាវថ្មីដែលអាចជួយយើងឱ្យច្នៃឡើងវិញនូវគំហើញលាយឡំពីប្រវត្តិសាស្ត្រផ្លូវទន្លេរបស់រាជធានីអង្គរ។ ទោះបីទំនាក់ទំនងរាជធានីអង្គរជាមួយបណ្តាញទន្លេត្រូវបានសិក្សារួចហើយកាលពីដើមសតវត្សទី២០នោះ ការសិក្សាដោយបែងចែកតាមផ្នែកដែលបានធ្វើរួចកន្លងមក លើប្រធានបទ សម្ព័ន្ធភាពរាជធានីអង្គរ ចំពោះបរិស្ថានផ្លូវទឹកបានបង្កឱ្យមានការបកស្រាយដែលមិនឆ្លុះបញ្ចាំងពីភាពសាំញ៉ាំនៃ ប្រធានបទនេះទេ។ អ្វីដែលត្រូវ ដេញដោលនៅក្នុងអត្ថបទនេះគឺបុរាណវិទូ ដែលមិនបញ្ចូលមធ្យោបាយផ្លូវសមុទ្រ ចូលក្នុងការសិក្សាវប្បធម៌ដែលដូចរាជធានីអង្គរ ដែលផ្លូវទឹកដើរតួនាទីសំខាន់ ក្នុងបរិស្ថានតំបន់នោះ ទំនងជាភ្លេចចំណុចសំខាន់នៃវប្បធម៌ផ្លូវទន្លេហើយ។ តាមរយៈការអនុវត្តទស្សនាទានដូចជាទេសភាពវប្បធម៌ផ្លូវសមុទ្រ អ្វីដែលអាចទៅរួច គឺការរុញឱ្យផុតព្រំដែនមធ្យោបាយផ្លូវគោក ហើយរកមើលថាតើលក្ខណ្ឌបរិយាកាសនៃវប្បធម៌ដូចរាជធានីអង្គរ ដែលមានប្រព័ន្ធទន្លេ ជាមធ្យោបាយប្រាស្រ័យទាក់ទងចម្បង បង្កឱ្យមានការអភិវឌ្ឍសញ្ញាណចំណេះ និងមុខងារជាក់លាក់ដែលបង្កើតជា ទេសភាពវប្បធម៌ផ្លូវទន្លេយ៉ាងណា។ ឧទាហរណ៍មួយនៃមធ្យោបាយបែបនេះ នឹងផ្តល់ជាការសន្និដ្ឋាន ក្នុងការវិភាគស្ពានកំបោរនានា នៅក្នុងបណ្តាញដឹកជញ្ជូនរបស់រាជធានីអង្គរ។
