Regional Sediment Management: Integrated Solutions for Sediment Related Challenges Hawaii Regional Sediment Management: West Maui Region; Nearshore Sedimentation at Honokowai Stream by Jessica H. Podoski, Lauren Molina, Zeki Demirbilek, and Lihwa Lin PURPOSE: This study was conducted as a conceptual effort, at an island scale as opposed to the extensive watershed scale within the continental United States, to apply the Coastal Modeling System (CMS) and the Particle Tracing Model (PTM) numerical models to investigate the transport and fate of inland sediment inputs to the nearshore littoral environment. In tropical islands with high elevations, terrestrial runoff can pose a severe threat to the health of surrounding coral reefs (Pinniak 2004). Because inland sediment input to the nearshore littoral environment is a coral reef stressor, the CMS and PTM were applied to better understand the circulation patterns along the coast that influence the transport and fate of the Honokowai stream sediment inputs within the nearshore littoral environment of the West Maui, HI, region. Further comprehensive three-dimensional (3D) modeling of the region is recommended to quantify cohesive sediment transport, temperature and salinity effects, and pre- and post-storm sedimentation data at coral reefs. BACKGROUND: Regional Sediment Management (RSM) refers to the effective use of littoral, estuarine, and riverine sediment resources in an environmentally sensitive and economically efficient manner. RSM was officially implemented at the U.S. Army Corps of Engineers (USACE), Honolulu District (POH), in February 2004. The POH overall RSM strategy is to investigate RSM opportunities along all regions in Hawaii and the U.S. Pacific Territories. Conceptual regional sediment budgets have been developed in various regions throughout the islands to gain a general understanding of the control that morphology and

The Tomas H. (Hinojosa) Molina Collection consists of .5 linear feet of documents including correspondence, personal, political, and religious papers about activities in which members of the family were involved, or discovered in their study of Duval County history. The collection also contains 379 images of family activities and historic events, most prominently, baseball teams from the early 1900s. Five photographs of Lyndon Johnson while he taught at Cotulla, TX in the early 1930s are included.
