MotivationMotivation

• Due to water scarcity during last 10+ years in Rio Grande/Bravo basin, it is necessary to:• Develop new reservoir/river simulation

models;• Determine available water in the basin

using hydrologic principles and actual data

• Provide data analysis capability necessary for improved water management and planning

33


ObjectivesObjectives

Develop a framework to create basinDevelop a framework to create basin--scale scale GIS databasesGIS databasesApply this framework to the Rio Apply this framework to the Rio Grande/Bravo basinGrande/Bravo basinDevelop a rasterDevelop a raster--network regionalization network regionalization technique for large river basins and apply it technique for large river basins and apply it to the Rio Grande/Bravo basin for delineating to the Rio Grande/Bravo basin for delineating watersheds and calculating hydrologic watersheds and calculating hydrologic parametersparameters
