Presentation Transcript

    1. Overview of National Water Services, Data Sources & Information Needs Belize Rudolph Williams Jr. Hydrologist Hydrology Unit National Meteorological Service - Belize

    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. Sources of Data Meteorological Monitoring Network

    6. Sources of Data Hydrological Monitoring Network

    7. Sources of Data Radar Observations

    8. DATA SOURCES Forecast Model Results

    9. Data Sources - Satellite Imagery

    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)
