  1. MBRS Watershed Hydrology Río Motagua, Río Chamelecón and Río Ulúa Paul Kirshen & Ned Spang

  2. Watersheds “an area of land within which all waters flow to a single river system” ---Heathcote 1998 “the specific land area that drains water into a river system or other body of water” ---The World Bank

  3. Features of a Typical Watershed Overland flow Groundwater flow Reef

  4. Río Motagua • Countries: Guatemala, Honduras • Watershed Area: 12,670km2 • Guatemala: 10,529 km2 • Honduras: 2,141km^2 • Average Annual Precipitation: 1,400 mm • Length: 487 km • Average Discharge: 530m^3/sec Source: Gulf of Honduras: Preliminary Transboundary Diagnostic Analysis, Final Draft (August 2003) Abt Associates/ Woods Hole Group, Global Environment Facility--Inter-American Development Bank Project Development Facility (PDF-B), pp. 5-6.

  11. Río Motagua: Water Quality 4 Dissolved Oxygen Saturation (%) Dissolved Oxygen (mg/L) Source: adapted from “Calidad de Agua de los Rios de La Republica de Guatemala” (December 2003), INSIVUMEH, Guatemala

  12. Findings & Stresses: Sufficient water quantity to meet needs Natural hydrology: peak rainfall conducive to high levels of erosion Even the limited water quality shows water quality stress and the value of water quality sampling Potential exists for future water quality problems from point and non-point source threats Climate Change? Interventions: Expand water quantity and quality monitoring Manage land use to respond to present and potential water quality threats Ensure effective management of wastewater Harmonization of transboundary water management Motagua: Conclusions

  13. Río Chamelecón • Countries: Honduras • Watershed Area: 4,350 km^2 • Average Annual Precipitation: 1,445 mm/yr • Length: 256 km • Average Discharge: ~370m^3/sec Source: Gulf of Honduras: Preliminary Transboundary Diagnostic Analysis, Final Draft (August 2003) Abt Associates/ Woods Hole Group, Global Environment Facility--Inter-American Development Bank Project Development Facility (PDF-B), pp. 5-6.

  17. Findings & Stresses: Sufficient water quantity to meet needs Significant lack of water quality data Potential exists for future water quality problems from point and non-point source threats Natural hydrology: peak rainfall conducive to high levels of erosion Climate Change? Interventions: Develop effective water quality monitoring programs Maintain consistent water quantity monitoring Manage land use to respond to potential water quality threats Ensure effective management of wastewater Río Chamelecón: Conclusions

  22. Findings & Stresses: Sufficient water quantity to meet needs in most areas Significant lack of water quality data Potential exists for future water quality problems from point and non-point source threats Natural hydrology: peak rainfall conducive to high levels of erosion Climate Change? Interventions: Plan for potential supply/demand imbalance in eastern portion of the watershed Develop effective water quality monitoring programs Maintain consistent water quantity monitoring Manage land use to respond to potential water quality threats Ensure effective management of wastewater Río Ulúa: Conclusions
