| Abstract | The Oceanside Littoral Cell, extending about 80 km southward from Dana Point in Southern California to Point La Jolla, is one of the most extensively studied coastal regions in the world and among the first to be investigated regionally. It is clearly defined by prominent rocky headlands at either boundary with evidence that there is little sediment exchange with neighboring cells. It is maintained by episodic river borne sediment inputs and erosion from the bluffs that back the majority of the beaches. It also suffers episodic losses of sand from the flushing of a submarine canyon near its southern boundary. The cell contains several coastal lagoons, some with jettied entrances and some connected to the sea episodically, hi addition to these jetties, a system of jetties and breakwater extensions was constructed to protect an artificial harbor at the city of Oceanside, roughly in the middle of the cell. With the exception of these entrances, the cell consists of continuous beaches throughout its length. The paper describes the Oceanside cell geography, the near-coast geology that impacts the beach and the physical forces that result in beach changes. It then discusses the background variability of beach volumes and the positive and negative impacts of human activities on the variations. To accomplish this analysis, the cell is divided into a small number of subregions with similar characteristics and histories. There is limited use of conventional profiles in the discussion. Emphasis is placed on changes to the recreational beach asset, that which is exposed at low tide. Seasonal, long-term and human-induced changes are separated to the extent possible for each of the subregions. Maps and aerial photography are utilized to illustrate the significant attributes. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
