The SegHidro is a Decision Support System
conceived as computational platform that
provides:
The aggregation of computing and storage resources
through grid computing middleware.
The sharing of data.
The discovery of data and resources through a
distributed information service.
The coupling of models through a workflow
composition tool.
Tools for enabling communication among users.
Current implementations:
Module for: data, storage and simulation models.
Simulation models of basin, aquifer and harvesting
systems behavior
Groundwater modelling
Regional impact of climate change

My visit to TTU
To diagnose some of the most important legal
and institutional frameworks related to
rainwater harvesting and aquifer management
of the State of Texas.
To improve the Early Warning System (EWS)
under development by considering the
uncertainties associated to climate forecasting,
monitored data and model parameterization.
The EWS includes the following components:
Basins and aquifers features, including time series of
monitored data.
Institutional and legal context.
Rainwater harvesting and aquifer simulation models.
Scenario generator procedures.
Scenario evaluation procedures.
Currently the following have already been
implemented:
Basic approaches to scenario generation and
evaluation.
Experiments in Brazilian semiarid aquifers and
rainwater harvesting systems had been made.
These experiments improved the parameterization
of small shallow aquifers and showed which EWS
components had to be improved.
Cooperation meetings and understands :
II WASLIC/ICASALS Conference in Gravatá – Brazil
Partnership between ICASALS (Dr. A. C. Correa) and CISA (Dr.
Carlos Galvao, UFCG) to appoint faculty and student
exchange.
ICASALS and WRC’s experience on semi-arid aquifer
modeling and management.
State of Texas advanced institutional framework on
rainwater harvesting.
Analysis of the legal and institutional frameworks of the State of
Texas related to rainwater harvesting and aquifer management,
through interviews with relevant actors in these settings.
The following institutions/companies/people will be
visited/interviewed:
ICASALS and WRC at TTU
Texas Water Development Board (focusing the Innovative Water
Technologies Group and Groundwater Resources Division)
Texas Rainwater Catchment Association members
Rainwater Harvesting Systems, Inc.
Improvement of the scenario generator and evaluation
procedures uncertainties associated to input variables
to take into account.
Water demands.
Seasonal rainfall forecasts.
Models parameterization.
Physical characteristics of aquifers and rainwater harvesting
systems with cisterns.
Sumé shallow aquifer, Paraiba, Brazil.
Relationship between groundwater
availability and water demands
Parameterization of the small shallow aquifer
Seasonal climate forecasts
Hydraulic heads estimate
Hydraulic heads variation
Uncertanties: water demands, seasonal rainfall
forecasts, and characteristics of aquifer.
Rainwater harvesting with cisterns
SJC1 Cistern
SJC1 Cistern: estimate vs observed water
volume in storage.
Water Demand and Model
Parameterization Uncertainties
Legal and Institutional Aspects
Brazilian public health regulations do not address
the quality of water in cisterns.
Which TX government policies promote water
harvesting through small systems?
What are integrated (Federal, State and Municipal)
water harvesting policies?
What are the legal aspects of water harvesting in
Texas?
What are the characteristics of the Texas harvesting
practices that could be applied in Northeastern Brasil?
Activities schedule
1. Data collection;
2. Data analysis and report writing ;
3. Improvement of modeling algorithms based on Texas water harvesting
practice.
