Treasure, Treason and the Tower

El Dorado and the Murder of Sir Walter Raleigh

By: Paul R. Sellin

In this remarkable book, the oft-told narrative of Sir Walter Raleigh is blown apart through the chance discovery of hitherto neglected Dutch correspondence found in a Swedish archive. Following an exciting paper-trail through Jacobean history to modern-day Venezuela, Professor Sellin makes a convincing case for Raleigh's innocence of the charges that led him to the block in 1618. Spurred on by these documents, Sellin undertook two excursions up the Orinoco river in Raleigh's wake, using Raleigh's 1596 book The Discoverie of Guiana as a guide. These trips convinced him that, far from being a fanciful blend of fact and fiction, the Discoverie is a remarkably accurate and verifiable document, which allowed him to locate Raleigh's gold lode on Cerro Redondo, a short distance inland from present-day Los Castillos, Venezuela. In place of a deceitful and scheming Raleigh, Sellin demonstrates how the Duke of Buckingham manoeuvred to have Raleigh executed on trumped-up charges. This left the way open for him to conspire with foreign powers to try to acquire the very mine he claimed Raleigh had invented to justify his actions against Spanish interests in Venezuela. It is rare for a scholarly book to profoundly shake widely-accepted views of so well-known an historical figure as Sir Walter Raleigh, but that is exactly what Paul Sellin achieves here. Crammed with tales of treasure, treason, murder, and international intrigue, this book make us think afresh of one of the greatest Elizabethan heroes. Written in a relaxed and engaging style, it will be of interest not only to specialists of the period but to anyone with a sense of the romance of history.

Practical Channel Hydraulics, 2nd edition

Roughness, Conveyance and Afflux

By: Donald W. Knight,Caroline Hazlewood,Rob Lamb,Paul G. Samuels,Koji Shiono

Practical Channel Hydraulics is a technical guide for estimating flood water levels in rivers using the innovative software known as the Conveyance and Afflux Estimation System (CES-AES). The stand alone software is freely available at HR Wallingford’s website www.river-conveyance.net. The conveyance engine has also been embedded within industry standard river modelling software such as InfoWorks RS and Flood Modeller Pro. This 2nd Edition has been greatly expanded through the addition of Chapters 6-8, which now supply the background to the Shiono and Knight Method (SKM), upon which the CES-AES is largely based. With the need to estimate river levels more accurately, computational methods are now frequently embedded in flood risk management procedures, as for example in ISO 18320 (‘Determination of the stage-discharge relationship’), in which both the SKM and CES feature. The CES-AES incorporates five main components: A Roughness Adviser, A Conveyance Generator, an Uncertainty Estimator, a Backwater Module and an Afflux Estimator. The SKM provides an alternative approach, solving the governing equation analytically or numerically using Excel, or with the short FORTRAN program provided. Special attention is paid to calculating the distributions of boundary shear stress distributions in channels of different shape, and to appropriate formulations for resistance and drag forces, including those on trees in floodplains. Worked examples are given for flows in a wide range of channel types (size, shape, cover, sinuosity), ranging from small scale laboratory flumes (Q = 2.0 1s-1) to European rivers (~2,000 m3s-1), and large-scale world rivers (> 23,000 m3s-1), a ~ 107 range in discharge. Sites from rivers in the UK, France, China, New Zealand and Ecuador are considered. Topics are introduced initially at a simplified level, and get progressively more complex in later chapters. This book is intended for post graduate level students and practising engineers or hydrologists engaged in flood risk management, as well as those who may simply just wish to learn more about modelling flows in rivers.
