PIs: Murugesu Sivapalan, Praveen Kumar, Bruce L. 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.

PIS：Murugesu Sivapalan，Praveen Kumar，Bruce L. Rhoads和Don Wuebblesabstractracthydrolologic Sc​​ience已经演变为拥抱来自各种纪律的科学家，这是由于现在存在于各种科学界面的界面上存在的许多挑战性问题所驱动的。已经取得了长足的进步，但是问题的巨大复杂性继续构成挑战，以预测塑造水文系统行为的物理，生物，生物地球化学和人类子系统之间的相互作用，尤其是在人类引起的气候和土地使用变化的背景下。注重单个组成部分或不变的景观或气候的预测不再被认为令人满意。因此，不断变化的环境既提供了一个挑战，也为开发良好的基础提供了通过基于观察，分析方法，概念，概念和理论的综合方法来改善水周期动态的可预测性，包括整体科学，生态学，地球学，地球学，地球化学，社会科学和社会科学，以使水与水的面对面，并面对现实，并与现成的面对面。该项目的目的是进行一系列综合活动，这些活动将在关键的研究领域产生变革性的结果，以“在不断变化的环境中提高水循环动态的可预测性”，这将是水文群落中合成的有效模型。通过形成有针对性的综合团队和相关的合成活动组，将实现这一目标，并通过这些组进行集中的研究活动，以产生结果，这些结果将充当国家综合功能的国家原型，以研究和解决复杂的水平问题。合成活动将包括研讨会，小组研究活动的组合，再加上网络基础结构的使用。为了实施该项目，已经成立了一个研究联盟，由几个既定的研究中心组成，作为合作伙伴（NCED，HWR/SAHRA，NCAR，NCAR，NCEAS，IRI，IRI，NCSA），用UIUC充当枢纽。合成团队和合成活动组的成员资格将向合作伙伴组织以及一般科学界开放。
