CONTROL of .ALLUVIAL RIVERS by STEEL JETTIES By
CONTROL OF .ALLUVIAL RIVERS BY STEEL JETTIES by E. 1. Carlson and R. A. Dodge, Jr. A paper to be presented at The First Water Resources Engineering Conference of The American Society of Civil Engineers, Omaha, Nebraska, May 14-18, 1962 CONTROL OF ALLUVIAL RIVERS BY STEEL JETTIES by E. J. Carlsonl / and R. A. Dodge, Jr. 2 / SYNOPSIS Both field and laboratory studies were conducted to refine the methods used in the design of steel jetty fields for river aline- ment. A set of dimensionless friction head-loss curves, verified by model studies are developed and described. Using the developed curves and reconnaissance field data, a method is given for predict- ing the changes in a riverbed after the designed jetty field is installed. /Head, Sediment Investigations Unit, Hydraulics Branch, Division of Engineering Laboratories, Bureau of Reclamation, Denver, Colorado. 2 /Hydraulic Engineer, Hydraulics Branch, Division of Engineering Laboratories, Bureau of Reclamation, Denver, Colorado. INTRODUCTION Steel jacks and jetties have been used successfully by the Corps of Engineers, highway departments, railway companies, and others to prevent damage to riverbanks, levees, bridge abutments, and other structures. The Bureau of Reclamation and the Corps of Engineers are using them to stabilize the channel of the Rio Grande within the floodway in the Middle Rio Grande Valley. (1)1 / The individual jack unit consists of three angle irons, 12 or 16 feet in length placed at 90° angles in three planes and joined at their cen- ters, Figure 1. Wire is laced through the angle irons in a standard pattern to tie them together. -

The CSA recalls that the JPC, at its second session, following its review of the Feasibility Study of the Senegal River Basin area entitled "Senegambia Project : Onchocerciasis Control in Guinea, Guinea-Bissau, l,la1i, Senegal and Sierra Leone", had asked the Prograrrne to prepare a Plan of Operations for implementing activities in this area. It notes that the Expert Advisory Conrnittee (EAC) recormnended an alternative strategy, emphasizing the need to focus, in the first instance, on those areas where onchocerciasis was hyperendemic and on those rivers which were sources of reinvasion of the present OCP area (Document JPC3.3). The CSA endorses the need for onchocerciasis control in the Western extension area. However, following informal consultations, and bearing in mind the prevailing financial situation, the CSA reconrnends that activities be implemented in the area on a scale that can be managed by the Prograrmne and at a pace concomitant with the availability of funds, in order to obtain the basic data which have been identified as missing by the proposed plan of operations. -

Livelihood Zone Descriptions
Government of Senegal COMPREHENSIVE FOOD SECURITY AND VULNERABILITY ANALYSIS (CFSVA) Livelihood Zone Descriptions WFP/FAO/SE-CNSA/CSE/FEWS NET Introduction The WFP, FAO, CSE (Centre de Suivi Ecologique), SE/CNSA (Commissariat National à la Sécurité Alimentaire) and FEWS NET conducted a zoning exercise with the goal of defining zones with fairly homogenous livelihoods in order to better monitor vulnerability and early warning indicators. This exercise led to the development of a Livelihood Zone Map, showing zones within which people share broadly the same pattern of livelihood and means of subsistence. These zones are characterized by the following three factors, which influence household food consumption and are integral to analyzing vulnerability: 1) Geography – natural (topography, altitude, soil, climate, vegetation, waterways, etc.) and infrastructure (roads, railroads, telecommunications, etc.) 2) Production – agricultural, agro-pastoral, pastoral, and cash crop systems, based on local labor, hunter-gatherers, etc. 3) Market access/trade – ability to trade, sell goods and services, and find employment. Key factors include demand, the effectiveness of marketing systems, and the existence of basic infrastructure. Methodology The zoning exercise consisted of three important steps: 1) Document review and compilation of secondary data to constitute a working base and triangulate information 2) Consultations with national-level contacts to draft initial livelihood zone maps and descriptions 3) Consultations with contacts during workshops in each region to revise maps and descriptions. 1. Consolidating secondary data Work with national- and regional-level contacts was facilitated by a document review and compilation of secondary data on aspects of topography, production systems/land use, land and vegetation, and population density. -
Shadow Colony: Refugees and the Pursuit of the Liberian
© COPYRIGHT by Micah M. Trapp 2011 ALL RIGHTS RESERVED SHADOW COLONY: REFUGEES AND THE PURSUIT OF THE LIBERIAN- AMERICAN DREAM BY Micah M. Trapp ABSTRACT This dissertation is about the people living at the Buduburam Liberian refugee camp in Ghana and how they navigate their position within a social hierarchy that is negotiated on a global terrain. The lives of refugees living in Ghana are constituted through vast and complex social relations that span across the camp, Ghana, West Africa and nations further afield such as the United States, Canada and Australia. The conditions under which these relations have developed and continue to unfold are mediated by structural forces of nation-state policies, the United Nations High Commissioner for Refugees (UNHCR), the international governing body for refugees, and the global political economy. Situated within the broader politics of protracted refugee situations and the question of why people stay in long-term camps, this research is a case study of one refugee camp and how its people access resources, build livelihoods and struggle with power. In particular, this dissertation uses concepts of the Liberian-American dream and the shadow colony to explore the historic and contemporary terms and circumstances ii through which Liberian refugees experience and evaluate migratory prospects and restrictions. iii ACKNOWLEDGMENTS The production of this dissertation has been an outcome of many places and people. In Washington, DC my committee members, Dolores Koenig, Geoffry Burkhart, and David Vine have provided patient support and provocative feedback throughout the entire process.

The Effects of Urban and Economic Development on Coastal Zone Management
sustainability Article The Effects of Urban and Economic Development on Coastal Zone Management Davide Pasquali 1,* and Alessandro Marucci 2 1 Environmental and Maritime Hydraulic Laboratory (LIAM), Department of Civil, Construction-Architectural and Environmental Engineering (DICEAA), University of L’Aquila, 67100 L’Aquila, Italy 2 Department of Civil, Construction-Architectural and Environmental Engineering (DICEAA), University of L’Aquila, 67100 L’Aquila, Italy; [email protected] * Correspondence: [email protected] Abstract: The land transformation process in the last decades produced the urbanization growth in flat and coastal areas all over the world. The combination of natural phenomena and human pressure is likely one of the main factors that enhance coastal dynamics. These factors lead to an increase in coastal risk (considered as the product of hazard, exposure, and vulnerability) also in view of future climate change scenarios. Although each of these factors has been intensively studied separately, a comprehensive analysis of the mutual relationship of these elements is an open task. Therefore, this work aims to assess the possible mutual interaction of land transformation and coastal management zones, studying the possible impact on local coastal communities. The idea is to merge the techniques coming from urban planning with data and methodology coming from the coastal engineering within the frame of a holistic approach. The main idea is to relate urban and land changes to coastal management. Then, the study aims to identify if stakeholders’ pressure motivated the Citation: Pasquali, D.; Marucci, A. deployment of rigid structures instead of shoreline variations related to energetic and sedimentary The Effects of Urban and Economic Development on Coastal Zone balances. -
