GEOTEXTILE TUBE and GABION ARMOURED SEAWALL for COASTAL PROTECTION an ALTERNATIVE by S Sherlin Prem Nishold1, Ranganathan Sundaravadivelu 2*, Nilanjan Saha3
PIANC-World Congress Panama City, Panama 2018 GEOTEXTILE TUBE AND GABION ARMOURED SEAWALL FOR COASTAL PROTECTION AN ALTERNATIVE by S Sherlin Prem Nishold1, Ranganathan Sundaravadivelu 2*, Nilanjan Saha3 ABSTRACT The present study deals with a site-specific innovative solution executed in the northeast coastline of Odisha in India. The retarded embankment which had been maintained yearly by traditional means of ‘bullah piling’ and sandbags, proved ineffective and got washed away for a stretch of 350 meters in 2011. About the site condition, it is required to design an efficient coastal protection system prevailing to a low soil bearing capacity and continuously exposed to tides and waves. The erosion of existing embankment at Pentha ( Odisha ) has necessitated the construction of a retarded embankment. Conventional hard engineered materials for coastal protection are more expensive since they are not readily available near to the site. Moreover, they have not been found suitable for prevailing in in-situ marine environment and soil condition. Geosynthetics are innovative solutions for coastal erosion and protection are cheap, quickly installable when compared to other materials and methods. Therefore, a geotextile tube seawall was designed and built for a length of 505 m as soft coastal protection structure. A scaled model (1:10) study of geotextile tube configurations with and without gabion box structure is examined for the better understanding of hydrodynamic characteristics for such configurations. The scaled model in the mentioned configuration was constructed using woven geotextile fabric as geo tubes. The gabion box was made up of eco-friendly polypropylene tar-coated rope and consists of small rubble stones which increase the porosity when compared to the conventional monolithic rubble mound. -
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. -

BULLETIN OF MARINE SCIENCE, 55(2-3): 1240-1250, 1994 COASTAL STRUCTURES, WASTE MATERIALS AND FISHERY ENHANCEMENT K. J, Collins, A. C. Jensen, A. P. M, Lockwood and S. J. Lockwood ABSTRACT Current U.K. practice relating to the disposal of material at sea is reviewed. The usc of stabilization technology relating to bulk waste materials, coal ash, oil ash and incinerator ash is discussed. The extension of this technology to inert minestone waste and tailings, contam- inated dredged sediments and phosphogypsum is explored. Uses of stabilized wastes arc considered in the areas of habitat restoration, coastal defense and fishery enhancement. It is suggested that rehabilitation of marine dump sites receiving loose waste such as pulverized fuel ash (PFA) could be enhanced by the continued dumping of the material but in a stabilized block form, so creating new habitat diversity. Global warming predictions include sea It:vel rise and increased storm frequency. This is of particular concern along the southern and eastern coasts of the U.K. The emphasis of coastal defenses is changing from "hard" seawalls to "soft" options which include offshore barriers to reduce wave energy reaching the coast. -

Numerical Modelling Approach for the Management of Seasonally Influenced River Channel Entrance
Numerical Modelling Approach for the Management of Seasonally Influenced River Channel Entrance Michael T. W. TAY Numerical Modelling Approach for the Management of Seasonally Influenced River Channel Entrance by Michael T.W. Tay Thesis Submitted in partial fulfilment of the requirements for the award of the degree of Doctor of Philosophy of the University of Portsmouth. 2018 i Abstract The engineering management of river channel entrances has often been regarded as a vast and complex subject matter. Understanding the morphodynamic nature of a river channel entrance is the key in solving water-related disasters, which is a common problem in all seasonally influenced tropical countries. As a result of the abrupt increase in population centred along coastal areas, human interventions have affected the natural flows of the river in many ways, mainly as a consequence of urbanisation altering the changes in the supply of sediments. In tropical countries River channel entrances are usually seasonally driven. This has caused a pronounced impact on the topography of river channel entrances especially in the East Coast of Borneo which is influenced by both North East (NE) and South West (SW) monsoons on top of related parameters such as waves and tides, sedimentation as well as climate change. Advanced numerical modelling techniques are frequently used as a leading approach to investigate the complicated nature of river channel entrances to represent the actual conditions of a designated area. Furthermore, the conventional ‘command and control’ approach of river channel entrance management has largely failed in this region due to the lack of process- based understanding of river channel entrances. -
Environmentally Friendly Coastal Protection the ECOPRO Project Abstract
Environmentally Friendly Coastal Protection The ECOPRO Project Brendan Dollard1 Abstract In the battle to preserve land against the ravages of the sea man has created many inappropriate protection structures on the coast. Often the coastline which is being protected is, inherently, in dis-equilibrium with nature. When combined with the increased recreational usage of the coastal zone, the rise in sea level and the increased incidence of storms, accelerated erosion rates are often the result. The Environmentally Friendly Coastal Protection project, or ECOPRO for short, developed a coastal erosion assessment method for the non-specialist. It devised a system for optimising erosion monitoring and developed a guide to select of an appropriate coastal protection response. The project results are contained in the ECOPRO Code of Practice. This 320-page guide explains the steps involved in assessing and monitoring coastal erosion problems, planning protective actions and evaluating their environmental impact. Prepared by the Offshore & Coastal Engineering Unit of Enterprise Ireland, it is the result of four years of work which was supported under the EU LIFE Programme and drew on expertise from Ireland, Northern Ireland and Denmark. This paper presents details of the project and the development of the Code. 1. Introduction In recent years it has become accepted that the coastline is a valuable natural resource which needs careful and sensitive management. This is especially so in the case of small island countries where the coastal zone has a direct and major influence on the economic welfare of the country. Coastal erosion has always been seen as one of the main threats to this resource and for centuries man has been fighting what was perceived as the ravages of the sea. -
