Chitresh Anand: Spatio-temporal trends in Indian Rainfall: Evolution over the past century
Abstract: The Indian rainfall pattern exhibits notable spatial heterogeneity and temporal variability, influenced by changing climate conditions and global warming. Despite extensive studies in the literature, there remains a lack of consensus regarding trend patterns in Indian rainfall. This study aims to analyze spatial and temporal trends in rainfall across the Indian landmass, focusing on the effects of data resolution on trend analysis. Utilizing daily rainfall data from the India Meteorological Department (IMD), both parametric and nonparametric tests are employed for trend detection, considering potential differences in methodologies. Results indicate that while varying data resolutions yield different outcomes, methodological differences also significantly impact trend results. Specifically, a cluster of grid points spanning central and eastern Indian landmass exhibits a notable decreasing trend, identified through field significance testing. Additionally, trends derived from rain gauge data are compared with those from gridded data, revealing the complexities introduced by missing values in rain gauge datasets Ultimately, the study underscores the importance of meticulously selecting datasets and trend analysis tools to accurately discern trends in rainfall data.
Layda Spor: A review on Hydrological impacts of Agricultural Conservation Practices
Abstract: The Conservation Reserve Program (CRP) is a voluntary land conservation initiative implemented by the U.S. Department of Agriculture (USDA) which aims to improve the natural environment. This review focuses on analyzing the effects of CRP on hydrological processes, highlighting the effects on water quality, groundwater levels, surface water yields, surface water runoff, and effects on the hydrological cycle.
