Thomas SoerensOISE- 1042778 U.S.-Sri Lanka Planning Visit: Hydraulics and Hydrology of Sri Lanka?s Dry Zone Tank Cascade Systems in a Changing Landscape This planning visit will initiate a new research collaboration between University of Arkansas (UA) Civil Engineering Professor Thomas Soerens and University of Sri Jayewardenepura (USJ) Geography Professor G.M. Bandaranayake to study the hydraulics and hydrology of the reservoir cascade system in Sri Lanka's dry zone. Sri Lanka, which has no natural lakes, has a network of about 18,000 small to large water reservoirs, called 'tanks', which date back to at least the fourth century BC. Their purpose is to reuse water over and over and to recharge groundwater. The tank cascade systems show a high degree of sophistication in their construction and design. During the visit, the co-investigators will visit field sites in the dry zone to identify research sites, design the subsequent research project, and meet with Sri Lankan government officials. Intellectual Merit- Professor Bandaranayake has studied the tank cascade systems using Landsat imagery and other geographic data, but now hopes to incorporate the engineering aspects of the systems. The collaboration with Dr. Soerens will bring expertise in hydraulics, water monitoring, and groundwater modeling and access to advanced geographic tools at UA?s Center for Advanced Spatial Technologies; Soerens will gain access to the field sites in Sri Lanka and the geographic expertise of his counterpart. This research collaboration will advance the study of the tank cascade systems, which to date have been studied only from historical, cultural, and geographic perspectives. The inclusion of quantitative investigations of their hydraulics and hydrology will advance understanding or these systems and enable the creation of a comprehensive model to analyze and predict the reaction of this important water resource in a changing landscape. Broader Impacts- The tank cascade systems are the critical water resource for Sri Lanka's dry zone, which faces stresses from climate change and changes in population. The results of the proposed research could be key in planning and management of water resources and other infrastructure. The proposed collaboration will lead to an ongoing program for students and researchers from UA and USJ to work together in the field and at the universities. The connection between the PIs, USJ, and CAST will strengthen the capability of the PI and his students in geographic analysis and hydrologic modeling. For UA students, the work will broaden their education as they consider the historical and social perspective of the tank systems. For UA students that participate in the field research, it will be a transformative experience.

托马斯SoerensOISE- 1042778美国-斯里兰卡规划访问：斯里兰卡的水力和水文？这次规划访问将启动阿肯色州大学（UA）土木工程教授托马斯·苏伦斯和斯里兰卡杰耶瓦德纳普拉大学（USJ）地理学教授G. M.班达拉纳亚克研究斯里兰卡干旱地区水库梯级系统的水力学和水文学。 斯里兰卡没有天然湖泊，但拥有约18，000个大大小小的水库，称为“坦克”，其历史至少可以追溯到公元前世纪。 它们的目的是重复利用水和补充地下水。 槽栅系统在其构造和设计方面显示出高度的复杂性。 在访问期间，共同研究人员将访问干旱地区的实地，以确定研究地点，设计随后的研究项目，并会见斯里兰卡政府官员。 知识专长-班达拉纳亚克教授利用陆地卫星图像和其他地理数据研究了坦克级联系统，但现在希望将该系统的工程方面结合起来。 与Soerens博士的合作将带来水力学，水监测和地下水建模方面的专业知识，并获得UA？Soerens将进入斯里兰卡的实地考察，并获得他的同行的地理专业知识。 这项研究合作将推进对罐级联系统的研究，迄今为止，这些系统仅从历史，文化和地理角度进行了研究。 对这些系统的水力学和水文学进行定量调查将促进对这些系统的理解，并建立一个综合模型，以分析和预测这一重要水资源在不断变化的景观中的反应。 更广泛的影响-水箱级联系统是斯里兰卡干旱地区的关键水资源，该地区面临气候变化和人口变化的压力。 拟议研究的结果可能是水资源和其他基础设施规划和管理的关键。拟议的合作将导致一个持续的计划，让来自UA和USJ的学生和研究人员在该领域和大学共同工作。PI、USJ和CAST之间的联系将加强PI及其学生在地理分析和水文建模方面的能力。对于UA学生来说，这项工作将拓宽他们的教育，因为他们考虑坦克系统的历史和社会视角。对于参加实地研究的UA学生来说，这将是一次变革性的经历。
