2. WHY IS AQUATOOLDMA A GOOD CHOICE? (5 of 7)
EVALHID
 Allows the development of continuous rainfall-runoff models to
assess the available water resources in complex river basins
 Applies aggregated models at subbasin scale, resulting in semidistributed models
 The results of surface runoff are obtained in each subbasin
 Considers that the river basins and the “underground basins” or
aquifers coincide from the top view. It provides the underground
runoff at the surface drainage points

2. WHY IS AQUATOOLDMA A GOOD CHOICE? (6 of 7)
SIMGES
 Solves the management of complex water resources systems with
surface and groundwater storage, intake, transport, artificial recharge,
use and consumption elements
 Applies a simulation-optimisation process through the equation:
Minimise TE  TR1  TR2  TR3  TR4  TR5  TDC  TDN  TRA  TBA 
 The management rules that can be implemented allow the
representation of complex real water resources systems
 Applies continuity for the surface subsystem and offers several aquifer
models for the groundwater simulation
2. WHY IS AQUATOOLDMA A GOOD CHOICE? (7 of 7)
GESCAL
 Simulates the evolution of constituents and pollutants in water
elements.
 The mechanistic models simulate the changes in water quality in a
natural system by attempting to represent the processes that occur in
the real system
 Simulates Water Quality for the entire system.
 Conventional constituents
o Temperature
o Dissolved oxygen
o Nitrogen cycle
o Phosphorous
o Phipoplankton
o Toxic pollutants
o Arbitraty constituents

5. HOW AQUATOOLDMA IS INVOLVED IN DECISION MAKING? (1 of 2)
Evaluate multiple alternatives for different scenarios
Sensitivity analysis
Problem identification
• Water Quantity
• Water Quality
Answer the next questions:
• What measures we have to take?
• What are the effect of these measures?
• Can we assume these effects?
• Can we achieve the environmental objectives?
5. HOW AQUATOOLDMA IS INVOLVED IN DECISION MAKING? (2 of 2)
Estimating Dissolved Oxygen
and amonium concentrations
in the critical point depending
on the flow
And all of these integrated with:
-Reliabilities of the demands
-Water quality in the rest of the basin

6. OTHER MODELS: GEOIMPRESS, PATRICAL Y MODFLOW
GEOIMPRESS is a simulation model which has
been build up in GIS platform (specifically
programmed in graphic script with ESRI
ModelBuilder in ARCGIS 9.2 environment)

The model works in GIS platform, with nonpoint
pollution pressures simulating parameters BOD5
(organic matter) and phosphorus.
MODFLOW is the U.S. Geological Survey (USGS)
modular finite-difference flow model, which is a
computer code that solves the groundwater flow
equation. The program is used by hydrogeologists
to simulate the flow of groundwater through
aquifers.
PATRICAL is a rainfall-runoff model that also
evaluates water quality. This is a distributed
model that reproduces the processes of runoff,
evapotranspiration, infiltration, surface flow and
groundwater flow at the basin scale and includes
capabilities to also simulate water quality.
