Approximately 60 bridges have been identified as potentially scour critical in the state of Hawaii based on observed or anticipated conditions at the bridges. These studies allowed the Hawaii Department of Transportation to prepare a Plan of Action (POA) for each bridge, which includes a scour vulnerability assessment and recommended actions, including a bridge closure plan.
Bridges involved in this effort cross waterways ranging from large, sand-bed rivers along the coastline of Oahu to the steep, rocky Hamakua Coast on the Big Island. Several bridges further inland are located on steep, cobble and boulder streams. A number of bridges on the historic Hana Highway on Maui are also included, with construction dating from as early as 1912. Drainage areas range from less than 0.5 km2 for some small coastal bridges to nearly 650 km2 for the Wailuku River (on the Big Island), which is subject to not only riverine scour, but also to scour from a tsunami-generated tidal bore.
Arc Hydro and ArcGIS were used to determine the areas contributing to streamflow at each bridge and flows were developed based on flood frequency gage analysis, regional regression equations, or published FEMA flows. Scour vulnerability of each bridge was determined by a detailed hydraulic analysis using HEC-GeoRAS and the HEC-RAS hydraulic model. Based on the scour vulnerability and foundation material and type, a POA was developed specific to each bridge describing procedures for Hawaii DOT personnel to follow during high flow events to ensure public safety.

The United States Army Corps of Engineers Honolulu District (USACE) completed a reconnaissance study to assess potential hydroelectric power sources across the State of Hawaii. The goal of the study was to compile existing information about potential sites identified for hydropower energy development and provide an assessment of the applicability of various hydropower generating technologies in Hawaii. GIS was used to support the assessment of the power potential of existing, retired and proposed traditional hydroelectric plants in the State. GIS was also used delineate areas preferential to ocean energy development through low-level marine spatial planning, screen potential sites based on environmental and social criteria as well as to visualize the results of the study. The study methods and key results will be presented, with an emphasis on how GIS and existing geospatial data at the State level were leveraged to complete the state-wide reconnaissance of hydroelectric power potential.

The Hawaiian Islands have one of the most diverse rainfall patterns on earth. Knowledge of these patterns is vitally important for a number of resource management issues, including the restoration and protection of native ecosystems, ground water and surface water development and protection, and planning for the effects of global warming. A new set of digital maps of mean monthly and annual rainfall from 1978-2007 for the major Hawaiian Islands has been developed. A monthly rainfall database was assembled with over 1,000 stations, using several gap-filling techniques to address missing values in the station records. "Virtual raingage" sites were estimated in remote areas based on patterns of natural vegetation. The final gridded maps were created using a Bayesian data fusion method that merged the station data with three predictor maps derived from Radar rainfall, MM5 model rainfall, and PRISM rainfall maps.
A new interactive website was created to make the rainfall maps, data, and related information easily accessible. Users can download map images, GIS and Google Earth layers, and station data or obtain information via an interactive map. To access the website, visit:

During summer 2010, Michigan State University partnered with the Hawai'i Fish Habitat Partnership (HFHP) and other organizations to complete a state-wide assessment characterizing Hawai'i stream condition. This assessment, conducted in support of the National Fish Habitat Action Plan, followed a landscape approach and used best available GIS data to characterize disturbances to stream habitat. We sought expert knowledge from local partners to select anthropogenic disturbance datasets, which were attributed to local and network stream catchments associated with individual reaches of the 1:24K National Hydrography Dataset. For each reach, disturbances at both scales were combined into a single cumulative score. Results of this work are being incorporated into the Atlas of Hawaiian Watersheds and are also being used by NOAA to assess effects of inland disturbances on priority coastal habitat. Despite its immediate utility, a refinement to the assessment is under way. Currently, we are developing a landscape-based classification of the ecological potential of Hawaii stream reaches. This classification will incorporate natural landscape variables that are unalterable by humans and climate variables known to be important in structuring physical and biological characteristics of streams. We will use a multi-step process to select influential variables and will rely on biological data to ensure ecological meaning of resulting groups. With streams classified into specific groups, we can characterize vulnerability to climate change on a reach by reach basis. Additionally, we can use the classification to refine the condition assessment, allowing managers to consider disturbance in the context of stream type.

GIS for Environmental, Community and Public Health
Tuesday March 6, 2012 - 10:45 am to noon
The Hawaii State Department of Health's Environmental Health Administration (EHA) has made great strides with GIS and geospatial technologies in recent years. EHA has integrated GIS capabilities into several applications to enhance finding and viewing environmental information across the state. We will showcase three separate systems developed at EHA that utilize GIS and geospatial tools.
EHA implemented an Environmental Health Warehouse in late 2009. This warehouse extracts information from the administration's environmental and health systems, reconciles the points of interest, and presents a holistic view of the data to consumers. A spatial inquiry system is used to find and explore known environmental information within locations and areas.
The Safe Drinking Water Branch designed and implemented a custom map viewer application, providing county and environmental health specialists ways to query water system, facility and sample point information. The solution also provides field users with a way to improve locational data with GPS-collected coordinates using custom mobile software on Trimble handheld devices.
The Clean Water Branch (CWB) created a custom water quality data viewer that gives internal and external users access to water quality data and beach warnings, advisories and postings. The system also includes a mapping utility that helps the CWB quickly and easily define affected locations and areas.
EHA has integrated ArcGIS Server technologies into many of its systems available inside and outside of the organization, often overlaying ArcGIS server layers over GoogleMaps as well as deriving geopolitical data to enhance the search capabilities of its inquiry tools.

Tuesday March 6, 2012 - 3:15 to 4:30 pm
The National Hydrography Dataset (NHD) is a comprehensive set of digital spatial data that contains information about surface water features such as lakes, ponds, streams, rivers, canals, dams and gages. Its rich set of attributes is continually maintained through system-wide revisions, a stewardship program, and contributions from the user community.
The NHD was designed to be simple enough for anyone with basic GIS skills to use, yet robust enough to allow for powerful geospatial analysis. These analyses are possible because the NHD contains a flow network that allows for tracing water upstream or downstream. It also provides a framework for linking scientific information such as water discharge rates, water quality, and aquatic population. These qualities give the NHD unique analytical powers for a number of scientific applications in the study of hydrology, pollution control, resource management, and fisheries biology.
This presentation will provide an overview of the structure of the NHD and its framework for linking scientific data to the NHD drainage network. Find out why the current generation of scientists and cartographers are adopting the National Hydrography Dataset as the standard for hydrography data. Hear how local partnerships continue to evolve this dataset to meet the challenges facing the earth sciences for the remainder of the century and beyond.
