Box 530,11000 Belgrade, Yugoslavia Preface Although the total amount of water on earth is generally assumed to have Remained virtually constant, the rapid growth of population, together with the extension of irrigated agriculture and industrial development, are stressing the quantity and quality aspects of the natural system. Because of the increasing problems, man has begun to realize that he can no longer follow a "use and discard" philosophy ~ either with water resources or any other natural resources. Asa result, the need for a consistent policy of rational management of water resources has become evident. Rational water management, however, should be founded upon a thorough understanding of water availability and movement. Thus, as a contribution to the solution of the worlds water problems, Unesco, in 1965, began the first world-wide programme of studies of the hydrological cycle - the International Hydrological Decade (IHD).

  • 1 Single-Layer Breakwater Armouring: Feedback on The
    SINGLE-LAYER BREAKWATER ARMOURING: FEEDBACK ON THE ACCROPODE™ TECHNOLOGY FROM SITE EXPERIENCE GIRAUDEL Cyril1, GARCIA Nicolas2, LEDOUX Sébastien3 The single-layer technique appeared at the beginning of the 1980s, with the ACCROPODE™ unit, and is thus entering its third decade. At the time, this solution was a real innovation, reducing the amount of concrete and steepening armour facing slopes, hence reducing the volume of materials required. After three decades in use and more than 200 projects to date, it was important to summarize the lessons learned during this period and to inspect (above and below water) some of these structures in order to assess their behaviour and particularly to confirm the validity of the unit placing rules. In addition to the aspects related to armour stability, the focus has been given to the colonization by marine life of the structures, including the bedding layers, toe berms, underlayer, armour units. The purpose of this paper is to share the experience gained throughout the inspections undertaken since 2010 on structures built more than 10 years ago. A large panel of structures has been inspected, of different ages and at various locations worldwide. Keywords: rubble-mound breakwater; single-layer armouring; ACCROPODE™ units; biodiversity INTRODUCTION The ACCROPODE™ armour unit, well known today, is a plain concrete unit designed to protect the breakwaters, in aiming to reducing considerably the use of material while implementing steeper slopes and a single layer of concrete units (Figure 1). Invented in 1981 thanks to the bases and knowledge acquired with the Tetrapod invented by the same engineering company in 1953, the technology is still currently used and more than 200 applications have been built worldwide.

  • Coastal Management Software to Support the Decision-Makers to Mitigate Coastal Erosion
    Journal of Marine Science and Engineering Article Coastal Management Software to Support the Decision-Makers to Mitigate Coastal Erosion Carlos Coelho * , Pedro Narra, Bárbara Marinho and Márcia Lima RISCO & Civil Engineering Department, Aveiro University, Campus Universitário de Santiago, 3810-193 Aveiro, Portugal; [email protected] (P.N.); [email protected] (B.M.); [email protected] (M.L.) * Correspondence: [email protected] Received: 4 December 2019; Accepted: 8 January 2020; Published: 11 January 2020 Abstract: There are no sequential and integrated approaches that include the steps needed to perform an adequate management and planning of the coastal zones to mitigate coastal erosion problems and climate change effects. Important numerical model packs are available for users, but often looking deeply to the physical processes, demanding big computational efforts and focusing on specific problems. Thus, it is important to provide adequate tools to the decision-makers, which can be easily interpreted by populations, promoting discussions of optimal intervention scenarios in medium to long-term horizons. COMASO (coastal management software) intends to fill this gap, presenting a group of tools that can be applied in standalone mode, or in a sequential order. The first tool should map the coastal erosion vulnerability and risk, also including the climate change effects, defining a hierarchy of priorities where coastal defense interventions should be performed, or limiting/constraining some land uses or activities. In the locations identified as priorities, a more detailed analysis should consider the application of shoreline and cross-shore evolution models (second tool), allowing discussing intervention scenarios, in medium to long-term horizons. After the defined scenarios, the design of the intervention should be discussed, both in case of being a hard coastal structure or an artificial nourishment (third type of tools).

  • Design & Construction of Coastal Structures
    DESIGN & CONSTRUCTION OF COASTAL STRUCTURES A.V. SITARAMA SARMA, Research Officer Central Water & Power Research Station, Pune 1. INTRODUCTION Coastal structures are the marine structure located in coastal waters. Marine structures can be broadly classified into two types: a) Offshore Structures and b) Near-shore Structures The design of Near-shore structures and offshore structures varies greatly in terms of environmental factors, depth of water etc. Offshore structures are located in deepwater and are subjected to forces due to short crested multi-directional waves, which are predominant, apart from other forces due to wind, ocean currents etc. The different types of offshore structure are:- Gravity Type Structures Pile Supported Structures Floating Structures Submarine Pipelines The near-shore structures can be grouped into:- Rigid structure – Sheet piles, Walls Semi-rigid or Composite structures – Caissons or cells on rubble base Flexible Structures – Rubblemound breakwaters, Sea walls Fig 1: Types of Near-shore Structures Training Course on Coastal Engineering & Coastal Zone Management Thus these near shore structures are subjected to various marine environmental forces due to waves, winds and currents. The wave forces are the dominant forces and are decisive in the design of near shore coastal structures. Rubblemound structures are the most commonly applied type for breakwater and seawall. The stability of rubblemound coastal structures depends primarily upon the stability of individual armour units on its seawards slope. The other hydrodynamic aspects of the effect of waves on the rubblemound are wave run-up, rundown, overtopping, reflection and transmission. Design of flexible rubblemound structures is complex as it involves various aspects such as wave-structure interaction interlocking, characteristics of armour, friction between armour and secondary layer etc.

Arif Rahman Hakim 51 Surabaya [email protected] ABSTRACT Coastal abrasion is one of the serious problems with shoreline change. In addition to natural processes, such as wind, currents and waves. One method for overcoming coastal abrasion is the use of coastal protective structures, where the structure functions as a wave energy damper at a particular location. Coastal buildings are used to protect the beach against damage due to wave and current attacks. Groyne is a coastal safety structure that is built protrudes relatively perpendicular to the direction of the coast, the importance of built coastal security with a groyne structure on the Jetis beach is as a flood control infrastructure that is as a final disposal of floods in the Ijo Watershed system, addressing coastal abrasion in detail. So we get the design drawings of sediment control buildings to reduce sedimentation / siltation from the direction of the sea into the river mouth, material structure costs and time schedule. Keywords: Abrasion, Groin, Material, Cost, Time Schedule. INTRODUCTION Research Background The problem at the Jetis beach is a estuary sedimentation, so that the flood discharge and economic activities of the people who use the river estuary channel as their fishing boat route are disrupted. Jetty or Groin which was built for the purpose of protecting the channel protrudes towards the sea to a distance of 300 m, with such conditions the river mouth is expected to get optimal protection.

It discusses the construction and operation of the multi-tubular floating sea wave damper that has been developed at the Maritime University of Szczecin by Professor Bolesław Ku´zniewski.This paper presents the results of the research project aimed at creating and examining a prototype of the device. The research aimed to confirm the two hypotheses: “the largest damping force should occur when the damping units are placed at an optimal distance equal to half the length of the wave to be damped” and “a compensation of the horizontal forces caused by the rippling of water should occur in the damping device”. Simulation studies of the behaviour of the device’s buoyancy elements when floating on waves were performed using the ANSYS AQWAWB and AQWA software. The buoyancy components were modelled as TUBE elements with a diameter of 0.11 m and a length of 1.5 m and as triangular and square surface elements. The results of the experimental research and the computer simulation of the operation of the prototype device have also been presented.

    ARTIFICIAL REEFS Concept & Indian Experience ENVIS - MoEF Newsletter on Coastal Zone Management Vol.9 (2) July - September 2010 and Coastal Shelterbelts Coastal Updates Visit our blog for latest news and events on Coastal Zone Management at www.iomenvis.in/coastal_updates Coastal zones are dynamic interfaces between land and water and are common locations of high-density development. Coasts are subjected to frequent natural hazards; including flooding, storm impacts, coastal erosion, and tsunami inundation. It is however, constantly adjusting to changes in wave and tide processes and sediment supply. As a result, the position of the coastline advances and retreats. This is a natural and expected process on sandy shorelines. Coastal managers are frequently faced with serious erosion of sandy coasts. Although possible causes of erosion could be natural processes (i.e. action of waves, tides, currents, sea level rise, etc.), human impacts (i.e. sand mining and coastal engineering works) overwhelmingly contribute to shoreline changes. Countermeasures for coastal erosion control function depend on coastal geomorphology, coastal processes and sediment transport. As an immediate solution to prevent coastal erosion, hard coastal protection structures such as ripraps, seawalls, groynes and breakwaters are used extensively. In modern times, artificial reef structures are increasingly utilized as submerged breakwaters, providing wave attenuation for shoreline erosion control plus habitat enhancement. Geosynthetic turf reinforcement mats or Geotubes, provide a low-cost alternative to hard armor on eroding critical areas and are effective bioengineering systems for shoreline stabilization. This issue of Coast track provides an overview of the various available methods for shore stabilization and coastal erosion control, with special emphasis on the alternative solutions, novel materials and systems, and various design implementations in Indian coasts.
