  1. Hydrology of the Hawaiian Islands Colleen Dawes, Energy and Earth Resources November 19, 2013

  2. Freshwater Resources: • Precipitation • Streamflow • Runoff • Soil moisture • Groundwater aquifers Hawaiian Islands

  3. Use GIS to explore the natural factors that influence freshwater distribution on Hawaii Elevation Topography Wind Direction Project Description

  4. Hawaii’s Topography and Elevation

  5. Wind Speed and Direction:Hawaii interrupts Pacific patterns

  6. Rainfall Elevation Trade Winds Rainfall Distribution:Influenced by Topography and Wind

  7. Rain Shadows Visualized:Vegetative Cover

  8. NHD Flowline: Maui Rain Shadows Visualized:Stream Location, Need for man-made diversion

  9. NHD Flowline: Oahu Part 2: Man-Made FactorsFreshwater Distribution and Artificial Paths

  10. Data I Have Data I Need Wind direction Other freshwater: snow, fog, soil moisture Time-Series Data: Flow and Consumption • Topography: DEM • Wind Speed • NHD • Monthly & Annual Rainfall Rasters • Aquifers & Streams Progress ReportQuantify relationships between topography, wind direction and flow
