What is the CISA Project?
Promotes cooperation among research centers to study semiarid region problems related water scarcity.
Involves universities and research organizations in Northeast Brazil, Portugal, Argentina, France and Cape Verde.
Funded by the Brazilian Ministry of Science and Technology (US $1.5 million)
CISA OBJECTIVES
1. Short-term Graduate Students Exchanges
2. Technical visits by researchers
3. Thematic meetings, workshops and mini courses
4. Research activities in selected watersheds in Northeast Brazil.

The CISTERNAS Project Objectives
To identify the relation between existing water laws and the institutions responsible for rainwater harvesting with cistern systems in rural areas of Northeastern Brazil.
To evaluate the application of federal water policies at the local level.
The CISTERNAS Project Motivation
Program: "one million cisterns for the Brazilian Semiarid”, has already
built 300 thousand rainwater harvesting systems and it is funded
by governmental and non-governmental sources.

Early Warning Systems
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.
The SegHidro Project
The SegHidro ProjectCurrent implementations:
Module for: data, storage and simulation models.Simulation models of basin, aquifer and harvesting systems behavior
Groundwater modelling
Regional impact of climate change scenarios

My visit to TTU
My visit to TTU Objectives
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.
My visit to TTU The Early Warning System
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:
Modules for data and storage and execution models.Basin and aquifer behavior simulation models
My visit to TTUBasic 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.
My visit to TTU Why TTU?
Cooperation meetings and understands :II WASLIC/ICASALS Conference in Gravatá – BrazilPartnership 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.
My visit to TTU Schedule Activities
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 TTUTexas Water Development Board (focusing the Innovative Water Technologies Group and Groundwater Resources Division)Texas Rainwater Catchment Association membersRainwater Harvesting Systems, Inc.
Use information obtained from visits/interviews to Brazilian EWS.
My visit to TTU Schedule Activities (cont.)
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.

SJC1 Cistern: estimate vs observed water volume in storage.
My visit to TTUPreliminary Results
Water Demand and Model Parameterization Uncertainties
Legal and Institutional Aspects
Brazilian public health regulations do not address the quality of water in cisterns.
My visit to TTUPreliminary Results
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?
My visit to TTUQuestions about water harvesting in Texas
Activities schedule1. Data collection;2. Data analysis and report writing ;3. Improvement of modeling algorithms based on Texas water harvesting practice.
