Book Description
This book is a collection of overview articles showing how space-based observations, combined with hydrological modeling, have considerably improved our knowledge of the continental water cycle and its sensitivity to climate change. Two main issues are highlighted: (1) the use in combination of space observations for monitoring water storage changes in river basins worldwide, and (2) the use of space data in hydrological modeling either through data assimilation or as external constraints. The water resources aspect is also addressed, as well as the impacts of direct anthropogenic forcing on land hydrology (e.g. ground water depletion, dam building on rivers, crop irrigation, changes in land use and agricultural practices, etc.). Remote sensing observations offer important new information on this important topic as well, which is highly useful for achieving water management objectives.Over the past 15 years, remote sensing techniques have increasingly demonstrated their capability to monitor components of the water balance of large river basins on time scales ranging from months to decades: satellite altimetry routinely monitors water level changes in large rivers, lakes and floodplains. When combined with satellite imagery, this technique can also measure surface water volume variations. Passive and active microwave sensors offer important information on soil moisture (e.g. the SMOS mission) as well as wetlands and snowpack. The GRACE space gravity mission offers, for the first time, the possibility of directly measuring spatio-temporal variations in the total vertically integrated terrestrial water storage. When combined with other space observations (e.g. from satellite altimetry and SMOS) or model estimates of surface waters and soil moisture, space gravity data can effectively measure groundwater storage variations. New satellite missions, planned for the coming years, will complement the constellation of satellites monitoring waters on land. This is particularly the case for the SWOT mission, which is expected to revolutionize land surface hydrology. Previously published in Surveys in Geophysics, Volume 37, No. 2, 2016

Book Description
Water resources are important to both society and ecosystems. However, humans put pressure on water resources with stresses that are likely to be exacerbated by the change in climate. Nonetheless, the lack of continuous data availability and inadequate monitoring networks has been a challenge to the scientific community. Recent advancements in satellite-based hydrology have demonstrated hydrologic variables can be measured from space with sufficient accuracy at limited regional and global scales (GRACE's spatial resolution is 200,000 km2). Therefore, research on the enhancement of the utility of satellite products in understanding and monitoring the water cycle at local scales (with size of 5,000 km2) is necessary, especially to complement studies in the absence or malfunctioning of in-situ observations. This dissertation sought to (1) estimate the spatial and temporal variation of hydrologic fluxes and storages at different scales using satellite remote sensing data, (2) assess the efficacy of publically available data (e.g. satellite remote sensing data) on our ability to predict/understand the terrestrial water cycle and the implications for water management, and (3) measure the relative effect of human-induced (e.g. abstraction) vs. climatic variability on the terrestrial water cycle. Moreover, the potential of multi-source datasets and integrated approaches for predicting the variability were evaluated. The work presented in this research has been conducted using a combined approach of processing and interpretation of satellite data, numerical modeling, analysis of in-situ data, and statistical and geospatial analysis in an effort to overcome data paucity. The results demonstrated the capability of GRACE at measuring water storage variations on a regional scale based on results from a robust integrated hydrologic model. Further, merging GRACE data with other data sources in an ANN (Artificial Neural Network) model reproduced the observed TWS (Terrestrial Water Storage) and groundwater storage anomaly at local scales. This downscaled product also replicated the natural water storage variability due to climatic and human impacts. Finally, the relative impact between humans vs. climate variability was distinguished and measured in Ethiopia using an integrated approach that can be transferable to similar settings. The implications utilizing satellite data for improving local and regional water resources management decisions and applications are clear. This is especially true with areas lacking hydrologic monitoring networks.

Book Description
This book discusses the water and carbon cycle system in the permafrost region of eastern Siberia, Providing vitalin sights into how climate change has affected the permafrost environment in recent decades. It analyzes the relationships between precipitation and evapotranspiration, gross primary production and runoff in the permafrost regions, which differ from those intropical and temperate forests. Eastern Siberia is located in the easternmost part of the Eurasian continent, and the land surface with underlying permafrost has developed over a period of seventy thousand years. The permafrost ecosystem has specific hydrological and meteorological characteristics in terms of the water and carbon dynamics, and the current global warming and resulting changes in the permafrost environment are serious issues in the high-latitude regions. The book is a valuable resource for students, researchers and professionals interested in forest meteorology and hydrology, forest ecology, and boreal vegetation, as well as the impact of climate change and water-carbon cycles in permafrost and non-permafrost regions.

Book Description
This volume provides in-depth coverage of the latest in remote sensing of hydrological extremes: both floods and droughts. The book is divided into two distinct sections – floods and droughts – and offers a variety of techniques for monitoring each. With rapid advances in computer modelling and observing systems, floods and droughts are studied with greater precision today than ever before. Land surface models, especially over the entire Continental United States, can map the hydrological cycle at kilometre and sub-kilometre scales. In the case of smaller areas there is even higher spatial resolution and the only limiting factor is the resolution of input data. In-situ sensors are automated and the data is directly relayed to the world wide web for many hydrological variables such as precipitation, soil moisture, surface temperature and heat fluxes. In addition, satellite remote sensing has advanced to providing twice a day repeat observations at kilometre to ten-kilometre spatial scales. We are at a critical juncture in the study of hydrological extremes, and the GPM and SMAP missions as well as the MODIS and GRACE sensors give us more tools and data than were ever available before. A global variety of chapter authors provides wide-ranging perspectives and case studies that will make this book an indispensable resource for researchers, engineers, and even emergency management and insurance professionals who study and/or manage hydrological extremes.
