Environmental problems in the humid tropical regions, where the focus is on the fate and management of the surviving rainforest and climate change, are attracting increasing attention internationally. The distribution of tropical rainfall is highly variable, and in many regions the supply of potable water is inadequate. By the end of the century one-third of the world's population will be living in the humid tropics. This book considers all aspects of hydrology in the humid tropics. The first four parts of the book cover the physical basis of hydrology in the humid tropics: climatology, meteorology, process hydrology, sedimentation, water quality and freshwater ecology. This is followed by extensive treatment of the human and societal issues: land-use changes, water resource management, and rural and urban water supply in the tropical regions. The book is a uniquely integrated summary of hydrology in the tropics.

The demand on land to produce food, for urban development such as housing, industry, shopping areas, infrastructure and also for recreation has increased during the history of mankind. This has resulted in such activities as the reclamation of swamps, flood plains, tidal areas and even lakes by impoldering. Model simulations can be use to gain insight into the system behaviour of different land use and soil composition under temperate humid and humid tropic conditions, The existing package OPOL, based on a non steady model, was further developed to the version OPOL5 for the simulation of hydrological conditions and optimization of the main components of water management systems in polder areas in the temperate humid and humid tropical zone. This model reveals a system's behaviour as well as the effects of variation in the main components of the systems to the overall costs. For example, the designs of pumped drainage systems in polder areas can be optimized by varying the main components until the annual equivalent costs are minimum. A GIS tool has been used to complement OPOL5 for the simulation of the real situation in an area with respect to land use, damage, topography, and soil type. The model package has been applied to two case studies: one in the temperate humid zone, namely the Netherlands and to Thailand in the humid tropical zone.

The movement of sediment and associated pollutants over the landscape and into water bodies is of increasing concern with respect to pollution control, prevention of muddy floods and environmental protection. In addition, the loss of soil on site has implications for declining agricultural productivity, loss of biodiversity and decreased amenity and landscape value. The fate of sediment and the conservation of soil are important issues for land managers and decision-makers. In developing appropriate policies and solutions, managers and researchers are making greater use of erosion models to characterise the processes of erosion and their interaction with the landscape. A study of erosion requires one to think in terms of microseconds to understand the mechanics of impact of a single raindrop on a soil surface, while landscapes form over periods of thousands of years. These processes operate on scales of millimetres for single raindrops to mega-metres for continents. Erosion modelling thus covers quite a lot of ground. This book introduces the conceptual and mathematical frameworks used to formulate models of soil erosion and uses case studies to show how models are applied to a variety of purposes at a range of spatial and temporal scales. The aim is to provide land managers and others with the tools required to select a model appropriate to the type and scale of erosion problem, to show what users can expect in terms of accuracy of model predictions and to provide an appreciation of both the advantages and limitations of models. Problems covered include those arising from agriculture, the construction industry, pollution and climatic change and range in scale from farms to small and large catchments. The book will also be useful to students and research scientists as an up-to-date review of the state-of-art of erosion modelling and, through a knowledge of how models are used in practice, in highlighting the gaps in knowledge that need to be filled in order to develop even better models.

Excess water in the urban environment results in flooding,which causes structural damage, risks to personal safety and disruption to city life. Water is also a major contributory factor for disease transmission as well as being the medium for transport of many pollutants. These problems are of increasing concern due to climate changes and are particularly apparent in the humid tropics. Integrated Urban Water Management in the Humid Tropics – the output of a project by UNESCO’s International Hydrological Programme on the topic – focuses on engineering aspects related to water supply, wastewater and stormwater management in the humid tropics. Flood control is dealt with a specific emphasis on reducing vulnerability to flood disasters in urban areas.The book also addresses environmental health concerns related to the different components of the urban water system and strategies for their control. The volume provides illustrations of different aspects of integrated water management in the urban environment by drawing upon a set of case studies – predominantly from South America. Urban Water Series - UNESCO-IHP, ISSN 1749-0790 Following from the Sixth Phase of UNESCO’s International Hydrological Programme (2002–2007), the Urban Water Series – UNESCO-IHP addresses fundamental issues related to the role of water in cities and the effects of urbanization on the hydrological cycle and water resources. Focusing on the development of integrated approaches to sustainable urban water management, the Series should inform the work of urban water management practitioners, policy-makers and educators throughout the world.

Climate change is expected to modify the hydrological cycle and affect freshwater resources. Groundwater is a critical source of fresh drinking water for almost half of the world’s population and it also supplies irrigated agriculture. Groundwater is also important in sustaining streams, lakes, wetlands, and associated ecosystems. But despite this, knowledge about the impact of climate change on groundwater quantity and quality is limited. Direct impacts of climate change on natural processes (groundwater recharge, discharge, storage, saltwater intrusion, biogeochemical reactions, chemical fate and transport) may be exacerbated by human activities (indirect impacts). Increased groundwater abstraction, for example, may be needed in areas with unsustainable or contaminated surface water resources caused by droughts and floods. Climate change effects on groundwater resources are, therefore, closely linked to other global change drivers, including population growth, urbanization and land-use change, coupled with other socio-economic and political trends. Groundwater response to global changes is a complex function that depends on climate change and variability, topography, aquifer characteristics, vegetation dynamics, and human activities. This volume contains case studies from diverse aquifer systems, scientific methods, and climatic settings that have been conducted globally under the framework of the UNESCO-IHP project Groundwater Resources Assessment under the Pressures of Humanity and Climate Change (GRAPHIC). This book presents a current and global synthesis of scientific findings and policy recommendations for scientists, water managers and policy makers towards adaptive management of groundwater sustainability under future climate change and variability.

The impact of climate on human activities and the effect of humans on cli mate are two of the most important areas of inquiry in climatology. These interactions conducted through physical, chemical and biological process es were described as early as Roman and Greek times. Marcus Vitruvius (75-25 B. C. ), a famous Roman engineer and architect, made the following observation about the climatic conditions necessary for founding a city: Land ideal for the health is slightly elevated and there should be neither fog nor frost. The direction of the slope and the distance to the swamps, lakes, and beaches must also be considered. The prevailing wind directions, observed by a wind tower at the center of the city, like Horologium at Athens, should be taken into consideration in city planning. The main and narrow streets should be placed in the middle angle of the two prevailing wind directions. Then the location of the Pantheons and squares should be decided. The influence of humans on climate was a major subject for discussion in the 19th century, inspired in part, by the rapid industrial growth and expanding deforestation of the time. D. L. Howard wrote brilliant pieces on the climate of London in the 1830s, while G . P. Marsh discussed the effects of forests on precipitation in the U. S . A. in the second half of the 19th century.
