Rhoads and Don WuebblesAbstractHydrologic science has evolved to embrace scientists from a diverse range of disciplines, driven by the many challenging problems that now exist at the interface of various science disciplines,. Tremendous strides have been made but the enormous complexity of the problems continues to pose challenges for predicting interactions among the physical, biological, biogeochemical, and human subsystems that shape the behavior of hydrologic systems, especially in the context of human-induced changes to climate and land use. Predictions focused on individual components or unchanging landscapes or climate are no longer deemed satisfactory. The changing environment therefore provides both a challenge and an opportunity for developing sound foundations for improving the predictability of water cycle dynamics through an approach based on a synthesis of observations, analysis methods, concepts and theories across a broad range of scientific fields, including hydrology, ecology, geomorphology, geochemistry, and the social sciences, in a manner sufficient to meet the water challenges we now face and will face in the future. The aim of this project is to conduct a range of synthesis activities that will produce transformational outcomes in the critical research area of "improving predictability of water cycle dynamics in a changing environment," which will serve as an effective model of synthesis within the hydrological community. This objective will be achieved by through the formation of a targeted synthesis team and associated synthesis activity groups, and through these groups, carrying out focused research activities to generate outcomes that will serve as national prototypes of the power of synthesis for investigating and solving complex hydrologic problems. The synthesis activities will consist of a mix of workshops, small-group research activities, combined with the use of cyber-infrastructure. To undertake this project, a research consortium has been formed consisting of several established research centers as partners (NCED, HWR/SAHRA, NCAR, NCEAS, IRI, NCSA) with UIUC acting as the hub. Membership of the synthesis team and synthesis activity groups will be open to partner organizations as well as the general scientific community.

Rhoads和Don Wuebrant摘要水文科学已经发展到拥抱来自不同学科的科学家，由许多具有挑战性的问题驱动，现在存在于各种科学学科的界面。已经取得了巨大的进步，但问题的巨大复杂性继续对预测物理，生物，地球化学和人类子系统之间的相互作用提出挑战，这些子系统塑造了水文系统的行为，特别是在人类引起的气候和土地利用变化的背景下。专注于个别组成部分或不变的景观或气候的预测不再被认为是令人满意的。因此，不断变化的环境为建立健全的基础提供了挑战和机遇，以便通过一种综合各种科学领域，包括水文学、生态学、地貌学、地球化学和社会科学的观测、分析方法、概念和理论的方法，提高水循环动态的可预测性，以足以应对我们现在和将来面临的水挑战的方式。该项目的目的是开展一系列综合活动，在“在不断变化的环境中提高水循环动态的可预测性”这一关键研究领域产生变革性成果，并将作为水文界综合的有效模式。这一目标将通过组建一个有针对性的综合小组和相关的综合活动小组来实现，并通过这些小组开展有重点的研究活动，以产生成果，这些成果将作为调查和解决复杂水文问题的综合力量的国家原型。综合活动将包括各种讲习班、小组研究活动以及利用网络基础设施。为了开展这一项目，成立了一个研究联盟，由几个已建立的研究中心作为合作伙伴（NCED，HWR/SAHRA，NCAR，NCEAS，IRI，NCSA）组成，UIUC作为中心。综合小组和综合活动小组的成员将向伙伴组织以及一般科学界开放。
