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). -

Table of Contents Page Welcome Message 1 Committees and Sponsors 2-6 General Information 7-9 APAC2011 Programme at a Glance 10-12 APAC2011 Oral Sessions 13-25 APAC2011 Poster Sessions 26-27 Keynote Lectures 29-72 Book of Abstracts 73-139 Welcome to APAC2011 It is our great pleasure to welcome you to this 6th International Conference on Asian and Pacific Coasts (APAC2011) and to the great city of Hong Kong. The Conference, hosted by The University of Hong Kong during December 14–16, 2011, aims to provide a platform where engineers and researchers can keep abreast of the current scientific and technological advancements in coastal and port-related research and practice. The response to our Call for Papers announced in March 2011 was very heartening. We ended up receiving more than 300 submissions from more than 30 countries around the world. After peer review, some 250 papers have been accepted for presentation at the Conference. This volume contains the APAC2011 Conference Programme and the Book of Abstracts. The programme consists of 6 keynote lectures, 4 invited lectures, 10 contributions to the Special Session on the 2011 East Japan Tsunami, and 237 other contributions arranged in various oral and poster sessions. These presentations cover a wide range of topics related to coastal, ocean and harbour engineering, such as beach erosion and morphodynamics, climate change and sea level rise, coastal management and shore protection, estuaries and ports, hydrodynamics of offshore and coastal structures, marine ecology and environment, marine and offshore wind energy, seawater intrusion, sediment transport, tsunami and storm surges, waves and tides, wastewater disposal and water quality, and so on. -
Simulation and Experimental Studies of a Multi-Tubular Floating Sea Wave Damper
energies Article Simulation and Experimental Studies of a Multi-Tubular Floating Sea Wave Damper Leszek Chybowski ID , Zenon Grz ˛adzieland Katarzyna Gawdzi ´nska* ID Faculty of Marine Engineering, Maritime University of Szczecin, 70-500 Szczecin, Poland; [email protected] (L.C.); [email protected] (Z.G.) * Correspondence: [email protected]; Tel.: +48-914-809-941 Received: 26 March 2018; Accepted: 11 April 2018; Published: 20 April 2018 Abstract: This article explores the issue of shore protection from sea waves and has presented the main methods used for coastal 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. -
Phd Thesis Wave Overtopping and Crown Wall Stability of Cube and Cubipod-Armored Mound Breakwaters
PhD Thesis Wave overtopping and crown wall stability of cube and Cubipod-armored mound breakwaters AUTHOR: Jorge Molines Llodrá SUPERVISED BY: Dr. Josep Ramon Medina Folgado Date: January 2016 A mi familia y amigos Wave overtopping and crown wall stability of cube and Cubipod-armored mound breakwaters Agradecimientos Tras varios años de trabajo presento esta tesis doctoral, que no habría sido posible sin el apoyo de las personas que me rodean. Ha habido momentos fáciles y otros menos fáciles pero todos ellos forman parte de esta tesis. A todas las personas que han participado de ellos están destinadas estas líneas. A mis padres y mi hermano: siempre conmigo al pie del cañón para tenderme una mano amiga o un comentario agradable en momentos en los que se torcían algunas cosas. A mis amigos, con quienes en muchas ocasiones no he podido pasar todo el tiempo que desearía. A la gran familia formada en el Laboratorio de Puertos y Costas, con quienes he compartido este largo viaje de principio a fin. Quique y Vicente, ¿aún recordáis aquél día que como buenos estudiantes íbamos preguntando por PFC y terminamos en el despacho de Josep? Ahí empezó nuestra andadura por el LPC y la época en la que íbamos en pack indivisible por la escuela y fuera de ella. Gracias Tomás y Guille por regalarme muy buenos momentos, donde una simple carcajada aliviaba la tensión de todo un día. Y por supuesto a Ainoha, Gloria y Cesar, quienes me habéis sufrido durante la última etapa de la tesis y con los que comparto mi día a día. -
Physical Modelling of Coastal Structures
Coastal Engineering Prof. V. Sundar Department of Ocean Engineering Indian Institute of Technology, Madras Module - 8 Physical Modelling Lecture - 1 Physical Modelling of Coastal Structure – I Now, this lecture module will be something about the Physical Modeling in Modeling in Coastal Engineering in general, dealing with a mostly coastal structures. And we will just looking into some of the aspects, why model testing? Problems that cannot be addressed by analytical or numerical modeling. (Refer Slide Time: 00:39) Naturally you have to resort to physical modeling. Non-linear affects such as wave breaking flow separation and overtopping of breakers or overtopping over break waters are mathematically extremely complex very difficult. Prediction equations for a given problem usually has empirical coefficients that need to be derived from tests, there are number of empirical coefficients. For examples, we have also seen in the long shore sediment transport proportionality constant, sediment transport to the immersed weight of the sand. Now, how do you get that proportionality constant may be you do some experiments or you do some field studies only then you can get some proportionality constant. In fact, how did you get the k d value for your breakwater, that is also based on experimental experimental studies. So, then to understand the underlying physics between the behind the problem; for example wave transformation pass a barrier. So, you have a barrier you have the wave transformation passed a barrier, what is the physics behind it. Now in order to understand the physics behind the any problem you also have the flow visualizing techniques, flow visualization techniques where you can under you can also look at the orbital paths. -

Abstrak Seawall merupakan salah satu bentuk konstruksi pelindung pantai yang berfungsi mencegah limpasan gelombang ke darat. Gelombang yang menghantam suatu bangunan akan naik pada permukaan bangunan (runup). Sehingga runup gelombang sangat penting dalam perencanaan sebuah bangunan pantai. Dalam penelitian ini dilakukan analisa runup gelombang pada pemodelan fisik seawall dengan variasi tinggi gelombang, periode gelombang dan sudut kemiringan struktur pelindung. BPPT-lock digunakan sebagai unit lapis lindung dengan pertimbangan kekuatan struktur lebih unggul dibanding dengan unit lapis lindung yang sudah ada serta dapat dipasang dengan pengaturan sederhana. Dari eksperimen yang telah dilakukan, nilai runup dari ketiga variasi kemiringan menunjukkan bahwa semakin kecil kemiringan struktur (curam) maka semakin besar nilai runup gelombangnya dan semakin besar kemiringan struktur (landai) maka semakin kecil nilai runup gelombangnya. -
