Improved Characterization of Hydroclimatic Extremes through the Development of a Comprehensive Nonstationary Modelling Framework

民用基础设施的分析、设计和管理需要对包括洪水和干旱在内的水文气候极端情况进行准确估计。现在人们普遍认识到，地球的气候，包括水文气候，不再是静止的，这在很大程度上是由于土地使用的变化和人类对地球气候的影响。洪水和干旱事件的前所未有的变化可能威胁到现有的基础设施，并对未来的设计提出挑战。该研究计划将开发创新框架，以准确估计区域和全球范围内的水文气候极端情况，从而实现更可持续的民用基础设施设计和管理。它包括三个短期目标，这三个短期目标构成了一个有凝聚力的、全面的、非静态的

Analysis, design, and management of civil infrastructure require accurate estimation of hydroclimatic extremes including floods and droughts. It is now widely recognized that the planet’s climate, including its hydroclimate, is no longer stationary, in great measure due to land-use change and human influence on Earth’s climate. Unprecedented changes in flood and drought events may threaten existing infrastructure and challenge future designs. This research program will develop innovative frameworks for accurate estimation of hydroclimatic extremes at regional and global scales, leading to more sustainable design and management of civil infrastructure. It comprises three short-term objectives, which constitute a cohesive and comprehensive nonstationary
