Observation of Rip Currents by Synthetic Aperture Radar
OBSERVATION OF RIP CURRENTS BY SYNTHETIC APERTURE RADAR José C.B. da Silva (1) , Francisco Sancho (2) and Luis Quaresma (3) (1) Institute of Oceanography & Dept. of Physics, University of Lisbon, 1749-016 Lisbon, Portugal (2) Laboratorio Nacional de Engenharia Civil, Av. do Brasil, 101 , 1700-066, Lisbon, Portugal (3) Instituto Hidrográfico, Rua das Trinas, 49, 1249-093 Lisboa , Portugal ABSTRACT Rip currents are near-shore cellular circulations that can be described as narrow, jet-like and seaward directed flows. These flows originate close to the shoreline and may be a result of alongshore variations in the surface wave field. The onshore mass transport produced by surface waves leads to a slight increase of the mean water surface level (set-up) toward the shoreline. When this set-up is spatially non-uniform alongshore (due, for example, to non-uniform wave breaking field), a pressure gradient is produced and rip currents are formed by converging alongshore flows with offshore flows concentrated in regions of low set-up and onshore flows in between. Observation of rip currents is important in coastal engineering studies because they can cause a seaward transport of beach sand and thus change beach morphology. Since rip currents are an efficient mechanism for exchange of near-shore and offshore water, they are important for across shore mixing of heat, nutrients, pollutants and biological species. So far however, studies of rip currents have mainly relied on numerical modelling and video camera observations. We show an ENVISAT ASAR observation in Precision Image mode of bright near-shore cell-like signatures on a dark background that are interpreted as surface signatures of rip currents. -

Energy and material are continually exchanged at the interfaces between water and air, ice, rocks, and sediments. In addition to the physical and chemical processes, biological processes play a significant role. Vast areas of the ocean remain unexplored. Investigation of the surface ocean is carried out by satellites. All other observations and measurements have to be carried out in-situ using research vessels and spe- cial instruments. Ocean observation requires the use of special technologies such as remotely operated vehicles (ROVs), autonomous underwater vehicles (AUVs), towed camera systems etc. Seismic methods provide the foundation for mapping the bottom topography and sedimentary structures. We cordially welcome you to the international OCEANS ’09 conference and exhibition, to the world’s leading conference and exhibition in ocean science, engineering, technology and management. OCEANS conferences have become one of the largest professional meetings and expositions devoted to ocean sciences, technology, policy, engineering and education. -

The Effect of Variable Grain Size Distribution on Beach's
Delft University of Technology Faculty of Civil Engineering and Geosciences Department of Hydraulic Engineering MSc Thesis THE EFFECT OF VARIABLE GRAIN SIZE DISTRIBUTION ON BEACH’S MORPHOLOGICAL RESPONSE Graduation committee: Prof.dr.ir. A.J.H.M. Reniers Author: Dr.ir. Matthieu de Schipper Melike Koktas Ir. Tjerk Zitman Dr. Edith L. Gallagher May 2017 P a g e 2 | 67 EXECUTIVE SUMMARY Field studies with in-situ sediment sampling demonstrate the spatial variability in grain size on a sandy beach. However, conventional numerical models that are used to simulate the coastal morphodynamics ignore this variability of sediment grain size and use a uniform grain size distribution of mostly around and assumed fine grain size. This thesis study investigates the importance of variable grain size distribution in a beach’s morphological response. For this purpose, first a field experiment campaign was conducted at the USACE Field Research Facility (FRF) in Duck, USA, in the spring of 2014. This experiment campaign was called SABER_Duck as an acronym for ‘Stratigraphy And BEach Response’. During SABER_Duck, in-situ swash zone grain size distribution, the prevailing hydrodynamic conditions and the time-series of the cross-shore bathymetry data were collected. The data confirmed a highly variable grain size distribution in the swash zone both vertically and horizontally. Additionally, the two trench survey observations showed the existence of continuous layers of coarse and fine sands comprising the beach stratigraphy. Secondly, a process based numerical coastal morphology model, XBeach, was chosen to simulate the beach profile response to wave and tidal action. A 1D cross-shore profile model was built and tested with the bathymetry data and accompanying boundary conditions that were collected during SABER_Duck. -

The Barnegat Bay Watershed Educational Resource Guide
Barnegat Bay Watershed Educational Resource Guide Prepared by Christine R. Raabe For the Ocean County Soil Conservation District and the Barnegat Bay Watershed Environmental Educators Roundtable Updated: March 2012 by the Barnegat Bay Partnership Table of Contents Introduction How to Use this Guide 1. Organizations and Agencies Involved with Barnegat Bay Watershed Education 2. National Organizations for Additional Resources 3. A Synopsis of Teacher Resources 4. Other Resource Guides and Directories 5. Map Resources 6. Barnegat Bay Watershed Environmental Educators Roundtable Steering Committee Members i Introduction The Ocean County Soil Conservation District and the Barnegat Bay Watershed Environmental Educators Roundtable discovered that educators within the watershed need assistance in finding pertinent information and resources if they are to effectively teach about the Barnegat Bay watershed and the issues that impact it. This guide has been compiled to answer that need. What began as a simple directory has grown into an annotated compendium of resources and organizations offering numerous programs, publications, field trips, and watershed information which educators can incorporate into their lessons and activities. It is a guide that will prove useful to anyone searching for information about the features and functions of the Barnegat Bay watershed. This Educator’s Resource Guide will be updated periodically. Please help us keep the document current by e-mailing Mary Judge at [email protected] with any additions, deletions, or corrections to the entries in this directory. Thank you for your help with this ongoing project. Original funding for this guide was provided by the USEPA and the NJDEP through the Barnegat Bay Partnership (BBP, formerly Barnegat Bay National Estuary Program) and the Partnership for Nonpoint Source Pollution Control in the Barnegat Bay Watershed. -

BOROUGH OF POINT PLEASANT BEACH STRATEGIC RECOVERY PLANNING REPORT OCEAN COUNTY, NEW JERSEY Executive Summary When Hurricane Sandy struck the coast of New Jersey on October 29, 2012, it brought extensive damage to Point Pleasant Beach Borough. A large number of residential properties and businesses suffered damage. Additionally, roadways were flooded and covered with sand, and electricity service was disrupted. The Borough also experienced damage to bulkheads, dunes, its boardwalk, and other important features. In response to the impacts of Hurricane Sandy, the Borough’s recovery efforts have been extensive. For example, it: evacuated residents; enacted a curfew and banned the sale of alcoholic beverages; filled barricades and cordoned off dangerous areas; responded to gas leaks and other disaster-related fire alarms and fires; cut and removed downed power lines; built a berm to protect property at the terminus of Arnold Avenue; cleaned sand from storm drains; made emergency repairs to sewer and water lines; removed storm-generated
