Settlement Systems in Sparsely Populated Regions: The United States and Australia provides an understanding of the special difficulties encountered by those living in sparselands and the issues facing government policy makers. This book discusses the regional aspects of human settlement as well as the regional differences in human welfare. Organized into 18 chapters, this book begins with an overview of the special set of characteristics and problems of sparsely populated regions. This text then describes the rapid changes affecting lightly populated areas. Other chapters consider the collective accessibility of any location in connection to the total national population as represented by maps of population potential. This book describes as well the more self-sufficient nucleated rural settlement of the far outback. The final chapter deals with the six general observations concerning sparsely populated lands thought to have applicability beyond just the United States and Australia. This book is a valuable resource for government policy makers.

This report presents the results of theoretical studies performed to understand and be able to predict better the response of "short" drilled shafts. A "short" drilled shaft has been defined as a shaft which undergoes less than two points of zero deflection when subjected to lateral loads. The first portion of this study was directed towards developing simplified procedures for estimating when a drilled shaft would respond as a "short" shaft, taking into account at least approximately the nonlinear response of the soil. The second portion of this study was directed toward improving the present procedure for predicting the response of "short" drilled shafts. Several modifications were made to existing procedures based on "p-y" curves to improve their ability to predict the response of short drilled shafts. These modifications were incorporated into a computer program with other modifications, which are presented in a companion project report
