This completely revised and enlarged second edition provides an up-to-date overview of all major topics in sedimentary geology. It is unique in its quantitative approach to denudation-accumulation systems and basin fillings, including dynamic aspects. The relationship between tectonism and basin evolution as well as the concepts of sequence cycle and event stratigraphy in various depositional environments are extensively discussed. Numerous, often composite figures, a well-structured text, brief summaries in boxes, and several examples from all continents make the book an invaluable source of information for students, researchers and professors in academia as well as for professionals in the oil industry.

Sediments are a natural part of aquatic systems and they are essential for the hydrological, geomorphological and ecological functioning of those systems. For society they are important and represent an important resource. However, due to the ever increasing use of river catchments, sediments need to be managed in a balanced and sustainable way. Sediment Management at the River Basin Scale reviews some of the key requirements and challenges facing scientists, river basin managers, and policy makers for sustainable sediment management at the river basin scale, and puts forward important recommendations. This volume also available as part of a 4-volume set, ISBN 0444519599. Discount price for set purchase. * First book to consider management at the basin scale* State-of-the-art review chapters* New conceptual frameworks and approaches to management

The degree of landscape connectivity has wide-ranging implications for sediment availability, frequency of transport, and the nature of sediment storage within a basin. Looking at the system as a whole, and identifying the connections that facilitate or impede sediment movement within a catchment is central to these applications. This thesis examines landscape connectivity within the highly diverse landscapes of the upper Yellow River (UYR) basin at a broad scale, with detailed focus on a smaller tributary that lies in the incised basin fill deposits of the Guide basin close to the margin of the Qinghai-Tibetan Plateau (QTP), the Garang subcatchment. Uplift of the QTP has resulted in a high-altitude landscape with a cold, semi-arid continental climate within the upper Yellow River. The region is characterized by several wide, low-relief basins separated by the two major mountain ranges (up to 2 km in relief) that run through the region, with tectonic deformation enduring within a series of strike-slip fault complexes. The thesis results are presented as a series of three papers. Findings are brought together in a discussion chapter. The first paper focuses on the pronounced variability in the landscapes of the upper Yellow River basin. The classification presented in this paper provides an effective organizational framework to describe the landscape diversity. Stark contrasts in landform assemblages and associated process relationships are evident across three very different terrains, reflecting the complex inter-relationships between tectonics, climate and surficial processes over time. A broad, low-relief, and highly disconnected upper plateau area at the headwaters of the UYR represents a relict peneplain that may have formed prior to regional uplift. The ranges of the Anyemaqen Shan in the central basin form a high-relief and highly connected landscape. Finally, the incisional story of the UYR dominates within the lower portion of the study area, where low-relief basin fills have been highly incised as a result of headward erosion of the Yellow River as drainage was established through the area. The second and third papers present a detailed examination of the landscape connectivity and sediment dynamics within the Garang study catchment. The second paper applies two methodological approaches for assessing landscape connectivity, a GIS-based geomorphometric index and a methodology linking interpretation of satellite imagery and field mapping of sediment storage to slope threshold analysis. Landscapes of the Garang catchment are differentiated into three geomorphic zones characterized by distinct landscape configuration and dominant geomorphic processes: i) a highly disconnected upper catchment of low-relief with large inactive sediment stores; ii) a transitional zone where present landscape dynamics are controlled in large part by past incisional processes in the form of large alluvial fan/terrace deposits; and iii) a highly connected and highly dissected landscape within the lower catchment that has little accommodation space for sediment storage. The findings from this paper emphasize the need for field-based observations that are capable of differentiating between landforms and activity levels of sediment stores, as well as providing inference on geomorphic process, that may not be evident with the use of cell-based morphometrics. The final paper expands upon these findings and presents an overview of sediment distribution and volume within the highly incised Garang catchment, combining field and GIS-based analyses. The magnitude and pattern of sediment storage is shown to be highly disparate between three distinct geomorphic zones of the Garang catchment. Findings of the study also reveal a somewhat unconventional pattern of sediment storage, whereby sediment storage is greater within the headwaters and decreases with distance downstream, adding to the range of landscape settings in which catchment-scale patterns of sediment storage have been assessed. The study also provides insight into the influence of long-term landscape evolution within the area, and how the response to lowering of the base level through Yellow River incision has impacted landscape connectivity and associated patterns of sediment storage and reworking within the catchment. Findings from both studies highlight the importance of field-informed appraisals of landscape dynamics, site-specific characteristics and the significance that basin-scale history can have on determining contemporary sediment dynamics. Issues associated with scales of analysis and the importance of localized influences are a key theme within the thesis. The final discussion chapter contextualizes findings of the thesis, focusing primarily on scale relations between landforms, geomorphic compartments (zones) and the subcatchment-scale analysis, and prospects to meaningfully up-scale these understandings to the UYR as a whole, linking analyses at the subcatchment scale to considerations of how we approach connectivity analyses across differing scales and contexts. Limitations and implications of the study are outlined.

Rivers provide the primary link between land and sea. Utilizing the world's largest database, this book presents a detailed analysis and synthesis of the processes affecting fluvial discharge of water, sediment and dissolved solids. The ways in which climatic variation, episodic events, and anthropogenic activities - past, present and future - affect the quantity and quality of river discharge are discussed in the final two chapters. The book contains 26 tables and more than 165 figures - many in full color - including global and regional maps. The book's extensive appendix presents the 1534-river database as a series of 44 tables and 132 maps that provide quantitative data regarding the discharge of water, sediment and dissolved solids. The complete database is also presented within a GIS-based package available online at www.cambridge.org/milliman. River Discharge to the Coastal Ocean provides an invaluable resource for researchers, professionals and graduate students in hydrology, oceanography, geology, geomorphology and environmental policy.
