Book Description :

Hydroclimatology provides a systematic structure for analysing how the climate system causes time and space variations (both global and local) in the hydrologic cycle. Changes in the relationship between the climate system and the hydrologic cycle underlie floods, drought and possible future influences of global warming on water resources. Land-based data, satellite data, and computer models contribute to our understanding of the complex time and space variations of physical processes shared by the climate system and the hydrologic cycle. Blending key information from the fields of climatology and hydrology - which are not often found in a single volume - this is an ideal textbook for students in atmospheric science, hydrology, Earth and environmental science, geography, and environmental engineering. It is also a useful reference for academic researchers in these fields.

Book Description :

The earth’s cryosphere, which includes snow, glaciers, ice caps, ice sheets, ice shelves, sea ice, river and lake ice, and permafrost, contains about 75% of the earth’s fresh water. It exists at almost all latitudes, from the tropics to the poles, and plays a vital role in controlling the global climate system. It also provides direct visible evidence of the effect of climate change, and, therefore, requires proper understanding of its complex dynamics. This encyclopedia mainly focuses on the various aspects of snow, ice and glaciers, but also covers other cryospheric branches, and provides up-to-date information and basic concepts on relevant topics. It includes alphabetically arranged and professionally written, comprehensive and authoritative academic articles by well-known international experts in individual fields. The encyclopedia contains a broad spectrum of topics, ranging from the atmospheric processes responsible for snow formation; transformation of snow to ice and changes in their properties; classification of ice and glaciers and their worldwide distribution; glaciation and ice ages; glacier dynamics; glacier surface and subsurface characteristics; geomorphic processes and landscape formation; hydrology and sedimentary systems; permafrost degradation; hazards caused by cryospheric changes; and trends of glacier retreat on the global scale along with the impact of climate change. This book can serve as a source of reference at the undergraduate and graduate level and help to better understand snow, ice and glaciers. It will also be an indispensable tool containing specialized literature for geologists, geographers, climatologists, hydrologists, and water resources engineers; as well as for those who are engaged in the practice of agricultural and civil engineering, earth sciences, environmental sciences and engineering, ecosystem management, and other relevant subjects.

Book Description :

The spatial and temporal variability of the hydro-climate as well as land use and land cover (LULC) changes are among the most challenging problems facing water resources management. Understanding the interaction between climate variability, land use and land cover changes and their links to hydrology, river morphology and ecohydrology in the Dinder and Rahad basins in Sudan is confronted by the lack of climatic, hydrological and ecological data. This book investigated the impacts of land degradation on the Dinder and Rahad hydrology and morphology, and interlinkage to the ecohydrological system of the Dinder National Park (DNP) in Sudan. It used an ensemble of techniques to improve our understanding of the hydrological processes and LULC changes in these basins. This included long-term trend analysis of hydroclimatic variables, LULC changes analysis, field measurements, rainfall-runoff modelling, hydrodynamic and morphological modelling of the Dinder river and its floodplain, with special focus on the Mayas wetlands. Moreover, this research is the first study to investigate the eco-hydrology of the DNP. It is expected that the results of the study will be beneficial to all stakeholders concerned and support decision-making processes for better management of water resources and ecosystem conservation in the area and possibly beyond.

Book Description :

A number of indicators of climatic trends in the Queen Charlotte Islands are examined in this report. The purpose of the analysis is to determine extent of climatic influence on recent increases in the incidence of slope failures and stream channel enlargement. Winter (October to April) total rainfall, precipitation, and snowfall; winter mean temperature; water-year (October to September) total stream run off; and the exceedance of daily precipitation amounts were studied using a variety of trend and data homogeneity analysis techniques. Although there was considerable lack of homogeneity foundin the various long-term data sets available from the Queen Charlotte Islands, and a low regional coherence between the data sets, several consistent climatic fluctuations were evident. The most notable are the periods of generally above-average winter rainfall and temperatures, 1923 to 1946, 1957 to 1964, and 1974 to 1984, with intervening periods of generally below-average winter rainfall and temperature, from 1946 to 1957 and 1964 to 1974. The most recent of these fluctuations (since 1946) appear to correspond with general changes in synoptic-scale circulation patterns across the northeastern Pacific Ocean area. The period since 1974, particularly significant to the Fish/Forestry Interaction Program, includes 7 years of exceptionally high precipitation in at least some portion of the Queen Charlotte Islands.

Book Description :

"Analysis on hydroclimatic variables can provide information on how the climate has evolved over time. This can be accomplished through time series analysis. Trend analysis in hydroclimatic variables is challenging due to their non-stationary nature and the presence of noise and stochastic components in them. The principal objective of this study is to detect and analyze trends in mean surface air temperature, total precipitation and mean streamflow obtained from several stations in Ontario and Quebec, Canada. To accomplish this, we co-utilized the wavelet transform (WT) technique (more specifically, the discrete wavelet transform (DWT)) and the Mann-Kendall (MK) trend test. The time series used were decomposed via the DWT in order to separate their high-frequency and low-frequency components, prior to testing their statistical significance with the MK trend test. The trend (i.e. slowly changing processes) is assumed to be contained in the low-frequency component of the data. The trends in temperature, precipitation and flow are assessed on different bases: monthly, seasonal, and annual. Temperature trends for the different seasons (i.e. winter, spring, summer, and autumn) were also assessed. In this study, we demonstrated the use of WT in extracting information contained in the time series that is not obvious in the raw data. The advantages of the WT technique are highlighted by its ability to extract time-frequency information contained in the analyzed time series manifested in the form of periodicities ranging from intra-annual to decadal events. A new criterion is also proposed in this study where the relative error of the MK Z-values between the approximation component of the last decomposition level and the original data was used to determine the number of decomposition levels of the analyzed time series, the type of Daubechies (db) mother wavelet, and the border condition to be used in the DWT procedure.The procedures contained in the methodology for trend analysis outlined in this study have not been explored in the existing literature. First of all, we tested for the presence of a significant autocorrelation in a time series prior to applying the MK test, which is often ignored in many trend detection studies. The time series were then decomposed via the DWT; the MK trend test and sequential MK test were then applied in order to determine the most significant periodic mode affecting the observed trends. In this study, three versions of MK test were used, depending on the characteristics of the analyzed data. The original MK test was used on data that exhibit neither seasonality patterns nor significant autocorrelations. Seasonal MK test by Hirsch and Slack (1984) was used on the time series exhibiting seasonality cycles (with or without significant autocorrelations). Modified MK test by Hamed and Rao (1998) was used on data with significant autocorrelations. Finally, combining the application of the DWT and MK test in trend assessment in hydroclimatic time series (especially in the context of Canadian studies) has not been explored. Therefore, the results obtained in this study contribute to furthering the overall understanding of climatic change in Southern Ontario and Quebec. Although the trends in the different variables studied are affected by different time periodicities, the study found that generally positive trends are more dominant. Among the most important findings of this study are: (i) all temperature data show positive values, which implies warming trends (ii) precipitation and flow trends are affected by fluctuations of up to four years, and (iii) annual positive trends in temperature may be attributed mostly by winter and summer warming. This suggests that if the temperature trends remain in the positive direction, other hydroclimatic indices may also experience significant changes in the future." --

Book Description :

"An underlying assumption of traditional hydrologic frequency analysis is that climate, and hence the frequency of hydrologic events, is stationary, or unchanging over time. A stationary series is relatively easy to forecast: one simply predicts that statistical properties will be the same in the future as they have been in the past. Anthropogenic climate change and better understanding of decadal and multi-decadal climate variability present a challenge to the validity of this assumption. The workshop ... was organized to present and discuss possible operational alternatives to the assumption of stationarity in hydrologic frequency analysis."--Abstract.
