Alluvial fans are gently sloping, fan-shaped landforms common at the base of mountain ranges in arid and semiarid regions such as the American West. Floods on alluvial fans, although characterized by relatively shallow depths, strike with little if any warning, can travel at extremely high velocities, and can carry a tremendous amount of sediment and debris. Such flooding presents unique problems to federal and state planners in terms of quantifying flood hazards, predicting the magnitude at which those hazards can be expected at a particular location, and devising reliable mitigation strategies. Alluvial Fan Flooding attempts to improve our capability to determine whether areas are subject to alluvial fan flooding and provides a practical perspective on how to make such a determination. The book presents criteria for determining whether an area is subject to flooding and provides examples of applying the definition and criteria to real situations in Arizona, California, New Mexico, Utah, and elsewhere. The volume also contains recommendations for the Federal Emergency Management Agency, which is primarily responsible for floodplain mapping, and for state and local decisionmakers involved in flood hazard reduction.

A revolutionary reimagining of the cities we live in, the air above us, and what goes on in the earth beneath our feet Today we live in a world that can no longer be read as a two-dimensional map, but must now be understood as a series of vertical strata that reach from the satellites that encircle our planet to the tunnels deep within the ground. In Vertical, Stephen Graham rewrites the city at every level: how the geography of inequality, politics, and identity is determined in terms of above and below. Starting at the edge of earth’s atmosphere and, in a series of riveting studies, descending through each layer, Graham explores the world of drones, the city from the viewpoint of an aerial bomber, the design of sidewalks and the hidden depths of underground bunkers. He asks: why was Dubai built to be seen from Google Earth? How do the super-rich in São Paulo live in their penthouses far above the street? Why do London billionaires build vast subterranean basements? And how do the technology of elevators and subversive urban explorers shape life on the surface and subsurface of the earth? Vertical will make you look at the world around you anew: this is a revolution in understanding your place in the world.
