项目摘要
This U.S. - Chile award will support a small workshop on alluvial fan research, accompanied with a field visit to the semiarid region of central Chile. The conditions under which climate variability in arid and semiarid regions affects sediment transfer and deposition from hillslopes to alluvial landforms are well documented in only a few regions in the world. In order to successfully expand knowledge on this multidisciplinary subject, research collaborations in paleoenvironmental reconstruction, paleoclimate, pedology and geomorphology are needed. This project will link complementary research expertise in Chile (Universidad del Norte, Universidad de La Serena, and Universidad de Chile) and the US (Desert Research Institute, DRI). Additionally, this new collaboration will link alluvial processes and landforms to Quaternary climate variability and result in the development of joint research projects. DRI will contribute expertise on soil and chronological analyses of alluvial landforms in arid regions around the world, while the Chilean researchers will contribute extensive experience on South America paleoclimate and geomorphology. The workshop will be organized by Dr. Jose Antinao from DRI in collaboration with Drs. Antonio Maldonado, Rodrigo Riquelme, and Gabriel Vargas from Universidad de la Serena, Universidad del Norte, and Universidad de Chile, respectively. The multidisciplinary nature of the proposed workshop and field visit will promote field-based interactions between researchers and students from both countries and will involve one early-career PI and one graduate student from the US. Furthermore, this project will allow for a broader testing of conceptual geomorphic models for alluvial fan evolution. Currently most of these models are derived from Northern Hemisphere sites. A more precise calibration of variables involved in these models will have a positive impact in our ability to predict effects of future global change in arid and semiarid alluvial landscapes. Improved forecasts of the combined hydrologic, ecological and geomorphic response of hillslopes, and associated alluvial systems, are of high societal relevance. They allow for efficient planning of resource allocation and mitigation of natural hazards, which benefits a large, vulnerable population across the globe. This workshop is supported by the Office of International Science and Engineering, Americas Program and the Directorate for Geosciences, Division of Earth Sciences, Geomorphology and Land Use Dynamics Program.
这项美国-智利奖将支持一个关于冲积扇研究的小型研讨会,并伴随着对智利中部半干旱地区的实地考察。干旱和半干旱地区的气候变化影响从山坡到冲积地貌的泥沙迁移和沉积的条件,在世界上只有少数几个地区得到了很好的记录。为了成功地扩展这一多学科的知识,需要在古环境重建、古气候、土壤学和地貌学方面进行研究合作。该项目将连接智利(北大、拉塞雷纳大学和智利大学)和美国(沙漠研究所,DRI)的互补研究专业知识。此外,这一新的合作将把冲积过程和地貌与第四纪气候变化联系起来,并导致制定联合研究项目。地球科学研究所将提供世界干旱地区土壤和冲积地貌年代学分析方面的专门知识,而智利研究人员将在南美洲古气候和地貌方面提供丰富的经验。研讨会将由DRI的Jose Antinao博士与分别来自Serena大学、北方大学和智利大学的Antonio Maldonado博士、Rodrigo Riquelme博士和Gabriel Vargas博士合作组织。拟议的研讨会和实地访问的多学科性质将促进两国研究人员和学生之间的实地互动,并将涉及一名职业早期PI和一名来自美国的研究生。此外,该项目将允许对冲积扇演化的概念地貌模型进行更广泛的测试。目前,这些模型中的大多数都来自北半球的站点。对这些模型中涉及的变量进行更精确的校准将对我们预测未来全球变化对干旱和半干旱冲积地貌的影响的能力产生积极影响。改进对山坡和相关冲积系统的水文、生态和地貌综合反应的预报,具有很高的社会意义。它们可以有效地规划资源分配和减轻自然灾害,使全球范围内的大量弱势人口受益。这次研讨会得到了国际科学与工程办公室美洲项目和地球科学理事会地球科学、地貌学和土地利用动态项目的支持。
