This research, focused on semi-distributed physically-based hydrological modeling in the tropics and subtropics, is represented in three parts. Part one aims to vigorously evaluate the performance of hydrologic model in simulating the hydrologic response of a subtropical data-rich gauged basin in the U.S., the Upper Kentucky River basin. Part two examines the performance and reliability of the validated model in a tropical data-poor ungauged basin in Central Vietnam, the Huong River basin. This part also studies total suspended solids concentration simulation beside river discharge and indentifies possible anthropogenic impacts on natural river flow. Part three is an assessment of water availability in the Vietnam basin for the twenty first century driven by projected climatic data from different Global Climate Models. The hydrologic model that is used in this research is the Soil and Water Assessment Tool (SWAT), a semi integrated physically-based watershed model. Hydrological modeling in this research takes advantage of the recent advances in Geographic Information Systems and Remote Sensing and employs publicly available products such as climatic data and Global Climate Model projections. Research results suggest that the SWAT model has good performance in the Upper Kentucky River basin and has the capability of reproducing daily discharge in alternative time periods and locations of the river. However, the SWAT model, driven by remotely sensed inputs, can only reasonably simulate runoff processes in absence of ground observations as in the Huong River basin. The study's results also indicate the continuous increase in summer and fall discharge of Huong River within the twenty-first century in A2 and B1 scenarios. In A1B scenario, HadCM3 and GFDL-CM2.1 models predict a decrease in river discharge from present to 2060s and then increase until 2080s; while ECHAM5-OM model produces opposite projection that discharge will increase until 2060s and then decrease for the rest of the century.

The world is facing severe and growing challenges in maintainig water quality and meeting the rapidly growing demand for water resources. In addition, water used for irrigation, the largest use of water in most developing countries, will likely have to be diverted increasingly to meet the needs of urban areas and industry whilst remaining a prime engine of agricultural growth. Finally, environmental and other in-stream water demands become more important as economies develop. The river basin has been acknowledged to be the appropriate unit of analysis to address these chanllenges facing water resources management: and modeling at this scale can provide essential information for policy makers in their decisions on allication of resources. This paper reviews the state of the art of modeling approaches to integrated water resources management at the river basin scale, with particular focus on the potential of coupled economic hydrologic models, and concludes with directions for future modeling exercises.

This book comprehensively accounts the advances in data-based approaches for hydrologic modeling and forecasting. Eight major and most popular approaches are selected, with a chapter for each — stochastic methods, parameter estimation techniques, scaling and fractal methods, remote sensing, artificial neural networks, evolutionary computing, wavelets, and nonlinear dynamics and chaos methods. These approaches are chosen to address a wide range of hydrologic system characteristics, processes, and the associated problems. Each of these eight approaches includes a comprehensive review of the fundamental concepts, their applications in hydrology, and a discussion on potential future directions.

New scientific discoveries in the Congo Basin as a result of international collaborations The Congo is the world's second largest river basin and home to 120 million people. Understanding the cycling of water, sediments, and nutrients is important as the region faces climatic and anthropogenic change. Congo Basin Hydrology, Climate, and Biogeochemistry: A Foundation for the Future explores variations in and influences on rainfall, hydrology and hydraulics, and sediment and carbon dynamics. It features contributions from experts in the region and their international collaborators. Volume highlights include: New in-situ and remotely sensed measurements and model results Use of historic data to assess precipitation and hydrologic changes Exploration of water exchange between wetlands and rivers Biogeochemical processes in the Congo's forests and wetlands A scientific foundation for hydrologic resource management in the region Studies from different parts of the Congo river and its adjoining basins This book is available in English and French. The American Geophysical Union promotes discovery in Earth and space science for the benefit of humanity. Its publications disseminate scientific knowledge and provide resources for researchers, students, and professionals. Find out more about this book in this short video and this article.

Hydrology is the science that deals with the processes governing the depletion and replenishment of water resources of the earth's land areas. The purpose of this book is to put together recent developments on hydrology and water resources engineering. First section covers surface water modeling and second section deals with groundwater modeling. The aim of this book is to focus attention on the management of surface water and groundwater resources. Meeting the challenges and the impact of climate change on water resources is also discussed in the book. Most chapters give insights into the interpretation of field information, development of models, the use of computational models based on analytical and numerical techniques, assessment of model performance and the use of these models for predictive purposes. It is written for the practicing professionals and students, mathematical modelers, hydrogeologists and water resources specialists.

Advanced Tools and Models to Improve River Basin Management in Europe in the Context of Climate Change - AquaTerra has developed from an integrated project of the 6th EU RTD Framework Programme that aims to provide the scientific basis for an improved river basin management through a better understanding of the river-sediment-soil-groundwater system as a whole, by integrating both natural and socio-economics aspects at different temporal and spatial scales. This book aims: To provide better understanding of the river-sediment-soil-groundwater system at various temporal and spatial scales To relate expected climate alterations to changes in deposition, mobility and distribution of pollutants in European river basins To provide the scientific basis for improved river basin management To introduce novel tools for water and soil quality monitoring To show the necessity of integrated modelling frameworks for impact evaluation of pollution as well as climate and land-use changes for definition of long-term management schemes The work illustrates the dynamic behavior of the pathway of pollutants in soils, groundwater, surface water and sediments. It highlights the fundamental importance of integrating knowledge from several combined disciplines on various environmental compartments in order to understand the large number of processes that govern pollutant input, transport and turnover. Results shows that a significant step forward has been made in the development new analytical methods and of process-based numerical models that are capable of making predictions of likely trends and environmental changes to be expected in the near or distant future at the basin-scale. These models can be used e.g. to generate hydrologic scenarios based on climate models and to simulate pollutant distribution and turnover rates from decades to millennia.
