Do you have what it takes to solve 100 dastardly puzzles set across the globe in a race-against-time to uncover the secretest secret of secrets? Summon your inner Dan Brown to catch the culprit and save the world.Renowned theologist Sir Gordon Gladstone has been brutally murdered at the British Museum, mere moments before revealing ‘the secretest secret of secrets’. After the Library of Alexandria was destroyed, its most sensitive document with this all-important secret was moved to a hidden location in Egypt – namely, inside the Sphinx. Just one problem: it’s no longer there!Put your Dan Brown hat on and retrace the footsteps of legendary puzzle solvers Professor Lawrence Lightwood (a cryptographer) and Doctor Dolores Delgado (a literary historian) to find the murderer, retrieve the secretest document, and prove yourself as a puzzle master of the highest order.Join Lightwood and Delgado on a puzzle-strewn chase around the world, with crosswords, sudoku, word searches, mazes, codes, logic puzzles and much, much more. Your quest will take you to ancient sites and great cities, but watch out, because a shadowy group known as S.C.O.W.L (The Secret Circle of Whispering Librarians) is searching for the secret and wants to keep you quiet … dead quiet.Featuring a wide variety of 100 fiendish and humorous puzzles ranging in difficulty, readers will have the option of following the story through from start to finish (with a tough bonus puzzles for those who have collected clues along the way) but each puzzle will also provide context for those who just fancy a quick fix. The Secretest Secret of Secrets is perfect for armchair detectives and adventurers who have what it takes to catch the culprit.

Much of the final shaping of the global landscape is accomplished by incision of river networks. The base-level is a principle determinate controlling the global relief by processes of erosion and aggradation. In the populated world, entrenchments triggered by base-level changes may become devastating events, damaging agricultural lands, undercutting bridges and destroying roads.The aim of this book, as a chapter in fluviomorphology, is to present the base-level control when active in the continental interior, unrelated to marine base-level fluctuations along the continental margins nor to sequence stratigraphic tract models in Exxon sequence stratigraphic sense. The focus is on the morphology and the gross trends of the processes controlling channel evolution through transient signals initiated by base-level changes and communicated upstream through the drainage network.The book brings together principles and conclusions gained by field work, by laboratory studies and by models, based on the widely scattered literature. The chapters include presentation of different types of base-levels, discussing the constraints of their altitude, the degradation and aggradation responses, the temporal and spatial trends along the channel network, the controlling factors, the knickpoint transient retreat process and its rates. Special emphasis is given to the Dead Sea Rift following its extreme base-level conditions which make it a unique field laboratory.This book is relevant to students in earth sciences as well as to planners, hydrologists and engineers dealing with geomorphology and surface drainage.

This book offers a comprehensive overview of the alluvial fan phenomena, including all terminology, morphology, sedimentology, controlling factors, processes and the human impact. It combines the knowledge dispersed widely in existing literature with regional case studies, color figures and photographs. The chapters provide a useful basis to understand alluvial fans and a selection of papers attached to each chapter offers additional, more focused reading. This volume is aimed at engineers, planners and especially students in earth sciences.
