| This work develops an understanding of the manner in which the observed large-scale climate variations (with multiple time scales) manifest in the surface hydrologic response. For the flood frequency analysis based on limited length record, a framework that recognizes the slow modes of climate can provide valuable insights into the assessment and design of hydraulic structures, reservoir operation, floodplain management, and resource allocation. The approach undertaken here is to carry out a systematic analysis of historical and model data, with a goal to understand the underlying factors that govern the relative sensitivity of extreme response to large-scale climate modes, in turn allowing the development of a new climate-based flood risk assessment framework. |
