Base Level Impact

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.

Focuses on lessons learned from four rounds of base realignments and closures (BRACs) held in 1988, 1991, 1993, and 1995. Addresses the applicability of these lessons to future BRACs as related to savings, costs, and economic impact; legislative actions needed to authorize future BRAC rounds; and what improvements would be needed in the Department of Defense's process for identifying bases for realignment and closure.

​The work investigates the impact of religiosity of women and men on their completed fertility in an international comparison considering a long time period. Sandra Hubert aims at uncovering all mechanisms through which religiosity and religious institutions can affect fertility. Hence, both the micro- and the macro-level of each country are explicitly integrated, and theoretically as well as empirically dealt with. The selection of differing countries rests upon the expectation that religiosity influences fertility decisions independently of the institutional context, social norms, state church-relations, and the national degree of religious vitality. These factors are intensively compared with each other at the country level. At the micro-level the impact of religiosity on fertility is tested by means of regressions and based on the Generations and Gender Survey. Results depend on gender, country, the diverse religious affiliations, and more.
