  1. Overview of National Water Services, Data Sources & Information NeedsBelize Rudolph Williams Jr. Hydrologist Hydrology Unit National Meteorological Service - Belize LIMA Water Cycle Capacity Building Workshop November 30 – December 4 2009

  2. Belize Location : northernmost Central American country. South of Mexico East & North of Guatemala Bounded on east by the Caribbean Sea. Area 8,867 mi2 ( 22,965 km2) Population ≈350,000 (mid 2008 est.)

  3. Belize has 4 Hydrological Regions 39 Identifiable watersheds 18 Classified as major watersheds 5 Transboundary watersheds Rio Hondo Rio Mopan Moho River Temash River Sarstoon River 6 Groundwater Provinces

  4. Water Services/Activities • Water classification for Potable, Agriculture, Industrial and Commercial water • Flood Forecasts • Drought Monitoring & Reporting • General water quantity & quality assessments • Protection and Conservation of water • Groundwater Assessment • Regulation of water abstractions • Resolution of water conflicts • Climate Change impacts on water resources

  5. 32 weather stations • 29 monitoring & reporting every 24hours via telephone • 2 monitoring every 15 minutes & reporting hourly via Satellite & NESDIS • 1 Synoptic weather station hourly monitoring & reporting via WMO GTS & internet Sources of Data Meteorological Monitoring Network

  6. Sources of Data Hydrological Monitoring Network 29 River level monitoring stations 24 staff gauges monitor every 12 hours & report every 72 hours via telephone 5 hydrological stations monitoring every 10 minutes and reporting hourly via satellite & NESDIS

  7. Sources of DataRadar Observations

  8. DATA SOURCESForecast Model Results GFS UKMET NAM MFEWS 01-06/12 2009 CAFFG

  9. Data Sources - Satellite Imagery GOES-FLOATER RAINBOW IR CH4 Oct 15 2008 Tropical Depression 16 2008

  10. DATA NEEDS • Flood Forecasts/Drought Monitoring & Reporting • Greater station density in the hydro-meteorological networks (more data needed – limited or no river level data in some watersheds) • Real or near real time reporting of rainfall and river levels (Reporting frequency in some watersheds is greater than time of concentration) • Algorithms to automatically convert models forecasts and radar observations to spatially referenced data for routine modeling (lumped watershed QPF, temperature, Eto, soil moisture, etc.) • Construction, refinement or replacement of hydrologic models (Coarse or no hydrologic models for some watersheds) • Construction of Hydraulic models ( no river channel models)

  11. DATA NEEDS Ground Water Assessments • Rapid assessment of the extent and capacity of the Groundwater Provinces – satellite image Analyses? (Increasing groundwater demand; very little knowledge, no comprehensive scientific studies conducted) Water Quality Assessments • Comprehensive program for the monitoring and reporting of surface and groundwater quality. (ad hoc program in place) Climate Change impact on Water Resources • Reconstruction of Historical datasets (Difficult to establish baselines due lack of historical data sets)
