Book Description
Land-use and land-cover (LULC) change is a continuous and dynamic process that is driven by human-induced activity. The North River watershed, located in Alabama, exemplifies patterns of forestry practices related to commercial logging that are present with the increasing frequency of intensive forestry practices across the Southeastern U.S. While many studies focus on expanding urbanization within watersheds and the effect on hydrology, there is a need to study effects on hydrology of newer forestry practices, which promote shorter regeneration and growth periods with more frequent tree harvest. Using the Soil and Water Assessment Tool (SWAT), a GIS hydrologic modelling program using watershed data (LULC, soil weather, elevation), a calibrated and validated model (NSE: 0.74 and 0.63, respectively) was produced and run for the study period of 2001-2018. LULC change trends between six NLCD LULC change periods (2001 to 2004, 2004 to 2006, 2006 to 2008, 2008 to 2011, 2011 to 2013, and 2013 to 2016) were examined and the impact on both discharge and water-balance components were analyzed. Using a KS-test on the distribution of climate de-trended monthly simulated discharges, three LULC change scenarios revealed statistically different distributions. With net forest loss in the watershed, water yield and subsequent discharge values increased; scenarios with forest gain resulted in water yield and discharge decreasing through various water-balance components analyzed in SWAT. These results suggest that LULC change can have effects on the hydrologic cycle with impacts on water yield through alteration of the water-balance variables.

Book Description
Agriculture is strongly affected by changes in soil hydrology as well as changes in land use and management practices and the complex interactions between them. This book aims to develop an understanding of these interactions on a watershed scale, using soil hydrology models and addresses the consequences of land use and management changes on agriculture from a research perspective. It includes case studies that illustrate the impact of land use and management on various soil hydrological parameters under different climates and ecosystems. It is suitable for researchers and students in soil sc

Book Description
This book offers a comprehensive overview of the challenges in hydrological modeling. Hydrology, on both a local and global scale, has undergone dramatic changes, largely due to variations in climate, population growth and the associated land-use and land-cover changes. Written by experts in the field, the book provides decision-makers with a better understanding of the science, impacts, and consequences of these climate and land-use changes on hydrology. Further, offering insights into how the changing behavior of hydrological processes, related uncertainties and their evolution affect the modeling process, it is of interest for all researchers and practitioners using hydrological modeling.

Book Description
This new edition is a major revision of the popular introductory reference on hydrology and watershed management principles, methods, and applications. The book's content and scope have been improved and condensed, with updated chapters on the management of forest, woodland, rangeland, agricultural urban, and mixed land use watersheds. Case studies and examples throughout the book show practical ways to use web sites and the Internet to acquire data, update methods and models, and apply the latest technologies to issues of land and water use and climate variability and change.

Book Description
This volume is a synthesis of the NASA funded work under the Land-Cover and Land-Use Change Program. Hundreds of scientists have worked for the past eight years to understand one of the most important forces that is changing our planet-human impacts on land cover, that is land use. Its contributions span the natural and the social sciences, and apply state-of-the-art techniques for understanding the earth: satellite remote sensing, geographic information systems, modeling, and advanced computing. It brings together detailed case studies, regional analyses, and globally scaled mapping efforts. This is the most organized effort made to understand the dominant force that has been responsible for changing the Earth’s biosphere. Audience: This publication will be of interest to students, scientists, and policy makers. This volume includes a CD-ROM containing full color images of a selection of illustrations which are printed in black-and-white in the book.

Book Description
There is a need of strengthening the global and local response to cope with the threat of climate change and adverse effects of rising anthropogenic activities in the mountain ecosystem. This book provides an up-to-date and comprehensive scientific and technical knowledge based on climate and land cover change impact assessment, adaptation and mitigation strategies in the Indian Himalayan watershed. The text updates the understanding scientific analysis to promote evidence-based policy formulation at regional and local levels. It can be used as reference materials with regards to climate and land cover change for those new learners interested in the mountainous region. This comprehensive book covers a wide range of potential research areas including climate change scenarios, science and its applications, adaptation to climate change-theory and assessment, water resources, agriculture, forest, biodiversity, and ecosystems, indigenous knowledge etc.

Book Description
This Festschrift containing sixteen invited essays and papers is a tribute to the distinguished Irish hydrologist James Dooge on the occasion of his 70th birthday. His former students, colleagues and friends in fourteen countries, have provided a varied selection on his favourite topics: flow in open channels and unsaturated soil, and also from his major interest of recent years, large scale hydrology and global change. The book has three sections. The first section on hydrological processes contains six papers. The second section on large scale hydrology has four papers. Six historical, reflective and philosophical essays on the past and future of the hydrological sciences form the third section of the book.

Book Description
This volume is a compilation of studies on interactions of land-cover/land-use change with climate in a region where the climate warming is most pronounced compared to other areas of the globe. The climate warming in the far North, and in the Arctic region of Northern Eurasia in particular, affects both the landscape and human activities, and hence human dimensions are an important aspect of the topic. Environmental pollution together with climate warming may produce irreversible damages to the current Arctic ecosystems. Regional land-atmosphere feedbacks may have large global importance. Remote sensing is a primary tool in studying vast northern territories where in situ observations are sporadic. State-of-the-art methods of satellite remote sensing combined with GIS and models are used to tackle science questions and provide an outlook of current land-cover changes and potential scenarios for the future. Audience: The book is a truly international effort involving U.S. and European scientists. It is directed at the broad science community including graduate students, academics and other professionals in this field.
