•
Simulates water demand, supply,
flows, and storage, and pollution
generation, treatment and
discharge.
Evaluates a full range of water
development and management
options, and takes account of
multiple and competing uses of
water systems
•
Quantifies the impact of
land management practices
in large, complex
watersheds.
Predicts impacts of weather,
soils, land use and land
management on water
supplies and pollution as well
as soil erosion, fertility and
crop production.
Test and recommend
reservoir release policies and
operations to meet current
and future water demands
while meeting downstream
regulations like minimum
environmental flows

Models’s Semantics to represent the watershed
components
Arc Hydro
SWAT
• Basin (highest level)
a set of administratively
chosen drainage areas that
partition a region for purposes of
water resources Management
• Watershed (highest level)
Delineated using DEM
• Watersheds
subdivision of a basin into
drainage areas selected for a
particular hydrologic purpose
• Sub-basin or sub-watershed
For areas that are dominated by
land uses or soils dissimilar
enough in properties to impact
hydrology
• Hydrologic Response Units
further discretization using land
use and soil type considerations
• Catchment
Elementary drainage areas defined
by a consistent set of physical rules.
Project Objectives:
• Design a conceptual data model to represent
reservoirs in water management models (WEAP, HECResSim, SWAT, and Arc-Hydro)
• Organize and deliver reservoir data to water
resources models above for Weber River Basin
Methods
• List data requirements for each model (entities,
attributes, and temporal and spatial representation)
• Develop a relational data model for each water
management model
• Design relational a data model that organize and
deliver reservoir data to water resources models
above for Weber River Basin
Progress and further
work
• Listed data requirement for
WEAP. HEC-ResSim to come.
• Developed a rough relational
data models the models
• Focus on the reservoir data
requirements
• Design the relational data model
that can transform reservoir data
to the selected models
Conclusions
• Water management models represent reservoirs with
different levels of attribute details
• Water management models use different semantics
for the same entities or attributes
• Relational data model would help to transform and
deliver reservoir water management data to different
models
