  • Broad Beach Restoration Project Coastal Development Permit
    Broad Beach Restoration Project Coastal Development Permit Project Description FINAL PREPARED FOR: TRANCAS PROPERTY OWNER’S ASSOCIATION PREPARED BY: 3780 KILROY AIRPORT WAY, SUITE 600, LONG BEACH, CA 90806 JANUARY 2011 JOB NO. 6935 1. INTRODUCTION 2 Broad Beach is located in the northwest portion of the County of Los Angeles and within the City of Malibu. The project area is comprised of the shoreline area fronting approximately 80 homes spanning approximately from Lechuza Point to Trancas Creek. Broad beach has been suffering shoreline erosion over the past 30 plus years, resulting in an almost complete loss of recreation and public access. Public access through dedicated public access ways from Broad Beach Rd. to the beach was rendered impossible during the most severe storms and tidal action over the past few years. The severe erosion problem now threatens private property and dune fields along this stretch of beach. The Trancas Property Owner’s Association (TPOA), representing almost all of the property owners along the Broad Beach shoreline, has elected to address the extensive erosion by privately funding a beach and sand dune restoration project which will not only protect their homes but also restore the beach to its historic grandeur not only for their benefit but for the benefit of the public at large. The Broad Beach restoration project seeks to design, permit, and implement a shoreline restoration program that provides erosion control, property protection, improved recreation and public access opportunities, aesthetics, and dune habitat. Broad Beach Restoration – Project Description FINAL The vicinity and location of the project site are shown below in figure 1.

The Yunlin coast, a first-level protection area in mid-west Taiwan, was then used as an example to illustrate the proposed design criteria. The safety of the present coastal defenses and land use of the Yunlin coastal area was assessed, and coastal protection measures for hazard prevention were proposed based on the generated risk map. The results can be informative for future coastal management and the promotion of sustainable development of coastal zones. Keywords: coastal defense; risk maps; non-engineering measure; coastal vulnerability 1. Introduction Like most developing countries, Taiwan’s coast has been alternatively used for settlement, agriculture, trade, industry, and recreation without careful and thorough planning in the development stage since 70s.

For this purpose we performed field studies, and collected information about these rivers. To predict depth of scour at groynes we used equations proposed by Khosla (1953), Garde et al (1961), Niel (1973), Zaghloul(1983), Ahmad (1953), Gill (1972) and Liu (1961).Our results showed that The groyne constructed on both rivers had performed their performance properly in spite of their design and application. The spaces between groynes and their length had been determined suitably in Sezar river, but it was not suitable in Kashkan river. Using poor materials, poor pier foundation, and improper lateral wall angle were their negative aspects Considering the armoring phenomenon, the river bed has reached a proper balance, and therefore, river protection and thus, erosion between two groynes was conducted properly. KEYWORDS: Kashkan River, Sezar River, river groyne, performance, scour depth, flow pattern, groyne- fields 1. INTRODUCTION Rivers are continuously changing under the influence of various factors including geology and topology of the region, properties of alluvial deposits in floodplain, hydrologic features of the basin, hydraulic condition of the flow, and human exploitations.

The U.S. program adopted an “end-to-end” approach—addressing regional, national, and local aspects of a truly functional warning system—along with multiple other hazards that threaten communities in the region. In partnership with the international community, national governments, and other partners, the U.S. program offers technology transfer, training, and information resources to strengthen the tsunami warning and preparedness capabilities of national and local stakeholders in the region.

This paper presents examples of long-term impacts of entrance jetties and training walls on coastal and estuary processes, gleaned from experience on the NSW coast. COASTALPROCESSES On coastlines with high transport rates of littoral drift, jetties have trapped sand inducing erosion on down-drift beaches at the Tweed River (Delft 1970) and Coffs Harbour (Lord & van Kerkvoort 1981). Another less-appreciated impact of jetties on coastal alignments has been the changes they can induce in near-shore wave patterns that, in turn, will re-align ocean Figure 1 - Left: Entrance to Newcastle Harbour (circa foreshores significantly (Miller & Nielsen 1995, Klein et al. 1850).

  • Concept Designs for a Groyne Field on the Far North Nsw Coast
    CONCEPT DESIGNS FOR A GROYNE FIELD ON THE FAR NORTH NSW COAST I Coghlan 1, J Carley 1, R Cox 1, E Davey 1, M Blacka 1, J Lofthouse 2 1 Water Research Laboratory (WRL), School of Civil and Environmental Engineering, The University of New South Wales, Manly Vale, NSW 2Tweed Shire Council (TSC), Murwillumbah, NSW Introduction On the open coast of NSW, many options exist to adapt to the hazards of erosion and recession. Perhaps the most common historical approach to counter the erosion and recession hazard is to construct a seawall or revetment to protect the existing foreshore. Other alternatives include the construction of a submerged breakwater, assisted beach recovery and/or beach nourishment. For beaches with a littoral drift imbalance, the construction of one or more groyne structures is a further possibility. This paper presents two different concept designs for a long term groyne field at Kingscliff Beach. Background Information Case Study: Kingscliff Beach Kingscliff Beach, located at the southern end of Wommin Bay on the far north coast of NSW (Figure 1), is a section of the Tweed coastline with built assets at immediate risk from coastal hazards. Ongoing erosion in the last few years has resulted in substantial loss of beach amenity and community land. Storm erosion episodes between 2009 and 2012 severely impacted the Kingscliff Beach Holiday Park (KBHP). This section is also affected by moderate ongoing underlying shoreline recession (WBM, 2001). To manage the Kingscliff Beach foreshore (Figure 2) in the longer term, Tweed Shire
