A Systems Approach to Modeling the Water-Energy-Land-Food Nexus, Volume II
This two-volume book describes a flexible and adaptive system-based methodology and associated guidelines for the management and allocation of community-based WELF resources. Over the next 50 years, rapid population, urbanization, and economic growth worldwide will create unprecedented demands for water, energy, land, and food (WELF) resources. The discussion on how to meet human needs for WELF resources and how to guarantee their respective securities has changed over time from looking at all four sectors in isolation to understanding their interdependency through the so-called WELF nexus. The approach presented in this book responds to the overall agreement in the WELF nexus literature tha...
Navigating the Complexity Across the Peace–Sustainability–Climate Security Nexus
Explores the interaction between the different components of peace and the relationship between peace, sustainability, and climate security using semi-qualitative and quantitative tools. Explains how climate adaptation and mitigation are related to peace or conflict. Presents generic system dynamics modeling that can be used in different contexts.
Rock Stress and Its Measurement
Rock masses are initially stressed in their current in situ state of stress and to a lesser natural state. Whether one is interested in the extent on the monitoring of stress change. formation of geological structures (folds, faults, The subject of paleostresses is only briefly intrusions, etc. ), the stability of artificial struc discussed. tures (tunnels, caverns, mines, surface excava The last 30 years have seen a major advance our knowledge and understanding of rock tions, etc. ), or the stability of boreholes, a in the in situ or virgin stress field, stress. A large body of data is now available on knowledge of along with other rock mass properties, is the state of stress in the near su...
Rock Anisotropy and the Theory of Stress Measurements
Any undisturbed rock mass is subject to natural stresses inclu ding gravitational stresses due to the mass of the overburden and possibly tectonic stresses due to the straining of the earth's crust and remanent stresses due to past tectonism. Knowledge of the in situ stress field must be integrated into any rock engineering design along with general rock mass characteristics such as de for mability, strength, permeability and time dependent behavior. For example, the choice of optimum orientation and shape of deep underground caverns or complex underground works will be controlled by the orientation and the magnitude of the in situ stress @ield if it is necessary to minimize stress concentra...
Increasing National Resilience to Hazards and Disasters
Natural disasters are having an increasing effect on the lives of people in the United States and throughout the world. Every decade, property damage caused by natural disasters and hazards doubles or triples in the United States. More than half of the U.S. population lives within 50 miles of a coast, and all Americans are at risk from such hazards as fires, earthquakes, floods, and wind. The year 2010 saw 950 natural catastrophes around the world-the second highest annual total ever-with overall losses estimated at $130 billion. The increasing impact of natural disasters and hazards points to increasing importance of resilience, the ability to prepare and plan for, absorb, recover from, or ...
Rock Mechanics
This volume presents the proceedings of a symposium on rock mechanics, held in the USA in 1995. Topics covered include: rock dynamics; tool-rock interaction; radioactive waste disposal; underground mining; fragmentation and blasting; theoretical and model studies; hydrology; and rock creep.
Introduction to Rock Mechanics
Introduces a new approach to rock mechanics called ``block theory,'' which formalizes procedures for selecting proper shapes and orientations for excavations in hard jointed rock. Applies block theory to rock slopes and underground excavations, and covers the Q theory of rock classification, the empirical criterion of joint shear strength, rock bolting, properties of weak rocks, statistical frequency of jointing, an empirical criterion of rock strength, and design of underground supports. Contains many new problems with worked-out solutions.

Global Technology
Engineers know what they mean by the word technology. They mean the things engineers conceive, design, build, and deploy. But what does the word global in the phrase global technology mean? Does it mean finding a way to feed, clothe, house, and otherwise serve the 9 billion people who will soon live on the planet? Does it mean competing with companies around the world to build and sell products and services? On a more immediate and practical level, can the rise of global technology be expected to create or destroy U.S. jobs? The National Academy of Engineering held a three-hour forum exploring these and related questions. The forum brought together seven prominent members of the engineering ...
