Описание: This book is an exhaustive investigation of surface and subsurface runoff generation processes in a tropical forested catchment. Different hydrological, hydrochemical, geophysical and numerical modelling methods were used to investigate the hydrological catchment response to geomorphological and hydro-climatic characteristics. The study covers different temporal and spatial scales, examining differences in catchment behaviour. It provides insight on the hydrological regime of a poorly gauged catchment subject to future water resources development under touristic and real estate development. The analysis is also applicable to similar catchments in South Pacific Coast of Nicaragua, which is quickly developing.

Описание: The key highlights of the book include an innovative rainfall classification methodology based on stormwater quality to support the planning and design of stormwater treatment systems.
Urban informal settlements or slums are growing rapidly in cities in sub-Saharan Africa. Most often, a sewer system is not present and the commonly-used low-cost onsite wastewater handling practices, typically pit latrines, are frequently unplanned, uncontrolled and inefficient. Consequently, most households dispose of their untreated or partially treated wastewater on-site, generating high loads of nutrients to groundwater and streams draining these areas. However, the fate of nutrients in urban slums is generally unknown. In excess, these nutrients can cause eutrophication in downstream water bodies. This book provides an understanding of the hydro-geochemical processes affecting the generation, fate and transport of nutrients (nitrogen and phosphorus) in a typical urban slum area in Kampala, Uganda. The approach used combined experimental and modeling techniques, using a large set of hydrochemical and geochemical data collected from shallow groundwater, drainage channels and precipitation. The results show that both nitrogen-containing acid precipitation and domestic wastewater from slum areas are important sources of nutrients in urban slum catchments. For nutrients leaching to groundwater, pit latrines retained over 80% of the nutrient mass input while the underlying alluvial sandy aquifer was also an effective sink of nutrients where nitrogen was removed by denitrification and anaerobic oxidation and phosphorus by adsorption to calcite. In surface water, nutrient attenuation processes are limited. This study argues that groundwater may not be important as regards to eutrophication implying that management interventions in slum areas should primarily focus on nutrients released into drainage channels. This research is of broad interest as urbanization is an ongoing trend and many developing countries lack proper sanitation systems.

Описание: This book is an integrated approach to present a detailed case study in order to address the taxonomic and ecological features of this planktonic choreotrich protists in an iconic tropical mangrove wetland - Sundarban. To identify each tintinnid species, emphasis is given with regards to taxonomic features accompanied by high resolution images. This work explores the interaction between man-induced stress and the impact of climate change which is threatening the tintinnid biodiversity, and suggests, for example, remedial measures by adopting sound management strategies. Tintinnids (Protozoa: Ciliata: Tintinnida) are a coherent group ecologically recognized as micro-zooplankton. They deserve special attention because of their unique biodiversity and their crucial, functional role in the marine food chain. This is a valuable reference source for students, researchers, policy planners and coastal managers engaged in the field of marine biology, microbial ecology and marine bio-resources.

Описание: This book offers a comprehensive and accessible guide covering various aspects of trace metal contamination in abiotic and biotic matrices of an iconic Indian tropical mangrove wetland – Sundarban. Divided into nine chapters, the book begins by discussing the fundamental concepts of sources, accumulation rate and significance of trace metal speciation, along with the impact of multiple stressors on trace metal accumulation, taking into account both tourist activities and the exacerbating role of climate change. The second chapter presents a detailed account of the sampling strategy and preservation of research samples, followed by exhaustive information on sediment quality assessment and ecological risk, instrumental techniques in environmental chemical analyses, quality assurance and quality control, along with the Sediment Quality Guidelines (SQGs). Using raw data, the sediment quality assessment indices (e.g., pollution load index, index of geoaccumulation, Nemerow Pollution Load Index etc.) and conventional statistical analyses are worked out and interpreted precisely, allowing students to readily evaluate and interpret them. This is followed by chapters devoted to trace metal accumulation in sediments and benthic organisms, as well as acid-leachable and geochemical fractionation of trace metals in sediments. The book then focuses on chemical speciation of butylin and arsenic in sediments as well as macrozoobenthos (polychaetous annelids). Finally, potential positive role of the dominant mangrove Avicennia in sequestering trace metals from rhizosediments of Sundarban Wetland is elaborately discussed. This timely reference book provides a versatile and in-depth account for understanding the emerging problems of trace metal contamination – issues that are relevant for many countries around the globe.

As a wetland of international importance located in China, the Poyang Lake Basin's incredible topographical and biological diversity has provided a congregating point for scientists from around the world to engage in cross-disciplinary research. In particular, the International Conference on Poyang Lake Complex Environment System was instrumental in bringing together scholars from China, North America, and Europe to explore the latest innovations in water resource science and watershed management.
Featuring cutting-edge research in watershed management presented at this landmark event, Wetland and Water Resource Modeling Assessment pairs the accounts of Poyang Lake with additional information on the important watersheds of North America and Asia to help facilitate the development of decision support tools. The book explains that successful ecosystem assessment and modeling requires three key criteria: 1. Large spatial scales in data collection and analysis must be used to encompass major watershed features 2. Landscape features are needed to appropriately characterize hydrological processes and ecosystem components 3. Management decisions must be linked to results to facilitate ecosystem assessment Through the study of the diverse watersheds featured in Wetland and Water Resource Modeling Assessment, such as Poyang Lake, government, academia, and Industry can obtain the innovative technical tools needed to stay on top of this active field.
