世界大部分地区都在见证气候变暖，预计未来这一趋势还会加剧。重要的是要评估流域水文学对这种变暖的反应。此外，人类相互作用和气候变化影响着流域的水量平衡。我们使用Budyko框架和两个参数(动态偏差和修正弹性)进行了贡献分析和弹性研究，以了解人为应力和气候变化对降水分配的参与及其与印度半岛55个集水区对气候变暖的水文弹性的关系。这里，23个集水区表现出对气候变暖变化的水文弹性(低偏离和高弹性)。只有37.14%的人为主导流域(人类活动对径流变化的贡献较大)具有弹性，而58.82%的气候主导流域具有弹性属性。印度西部和最南部的大多数集水区在水文方面没有弹性。在关键气候条件下(在我们的研究中，气候变暖)，广泛的人类相互作用往往偏离预期的水文功能，导致水文弹性下降。
Most parts of the world are witnessing climatic warming and the trend is expected to increase in the future. It is important to assess the response of watershed hydrology to this warming. Moreover, human interactions and climatic variability influence the water balance of a catchment. We perform contribution analysis along with resilience study using Budyko framework and two parameters (dynamic deviation and modified elasticity), in-order to comprehend the involvement of anthropogenic stress and climatic variance on partitioning of precipitation and their relation with hydrologic resilience to warming shifts across 55 catchments in peninsular India. Here, 23 catchments have displayed hydrologic resilience (low departure and high elasticity) to climatic warming shifts. Only 37.14% of anthropogenic dominated catchments (higher contribution from human activities in runoff changes) were found to be resilient whereas 58.82% of climate dominated catchments had resilience attributes. Most of the catchments on western and extreme southern part of India were not hydrologic resilient. Extensive human interactions tend to depart the catchment from expected hydrological functioning under critical climatic conditions (Warming in our study) that lead to declining of hydrological resilience.
