Doctoral Dissertation Research: Fluvial Responses to Climate Change and Human Activities in Burgundy, France

STraffin南伊利诺伊大学卡本代尔分校论文改进研究：河流对气候变化和人类活动的反应，法国勃艮第拟议的研究将开发一个模型，将法国勃艮第的Arroux-Loire河水系的河流过程、洪水制度、土地利用模式和主要气候制度联系起来。该模式将提供对过去气候和环境变化的河流响应的重建，以及对不久的将来区域气候人为变化的河流响应的预测。200多年来河流景观变化的记录将从制图和遥感数据中发展出来。这些变化将在已知的土地利用模式以及气候和河流排放制度的历史性变化的背景下进行解释。然后，将为历史监测时期开发的模型与较老的冲积沉积、史前土地利用和相关的替代古环境数据的重建进行比较，以确定过去2000年河流沉积和侵蚀过程与气候制度之间的关系。如果该模型将气候制度和河流类型联系起来，这对较老的冲积沉积是有效的，那么就有可能预测同一地区河流对未来气候变化的响应。通过这种方式，这项研究提供了将全球环境变化与景观变化联系起来的第一步，使那些具有关键土地使用需求的地区能够更好地规划未来潜在的环境变化

SBR-9506643 Michael D. Blum Eric C. Straffin Southern Illinois University at Carbondale Dissertation Improvement Research: Fluvial Response to Climate Change and Human Activities, Burgundy,France The proposed research will develop a model that relates fluvial processes, flood regimes,land-use patterns, and dominant climate regimes for the Arroux-Loire River system in Burgundy, France. The model will provide for the reconstruction of fluvial responses to past climate and environmental changes, as well as for the prediction of fluvial response to anthropogenic changes in regional climate in the near future. Documentation of over 200 years of changes in the fluvial landscape will be developed from cartographic and remotely-sensed data. Those changes will then be interpreted within the context of known land-use patterns, and historic changes in climate and river discharge regimes. Models developed for the period of historical monitoring will then be compared with reconstructions of older alluvial deposits, prehistoric land-use, and correlative proxy paleoenvironmental data to determine the r elationship between fluvial depositional and erosional processes and climate regimes over the last 2000 years. If the model correlates climatic regimes and fluvial styles, and this is valid for older alluvial deposits, then it may be possible to predict fluvial responses to future climate change for the same region. In this way the study provides a first step towards linking global environmental change with changes in landscape, enabling those regions with critical land-use needs to better plan for potential future environmental change
