ANA Hydrological System: Portals and Products Overview

The Agência Nacional de Águas e Saneamento Básico (ANA), or National Water and Basic Sanitation Agency, plays a crucial role in managing and regulating water resources in Brazil. A key aspect of this role involves the operation of a comprehensive Hydrological Information System (HIS). This system comprises various portals and products, each designed with specific objectives to ensure effective water resource management. Understanding the purpose of each component is essential for stakeholders, researchers, and the public to leverage the wealth of data and tools provided by ANA. Let's dive into the objectives of each portal and product within ANA's Hydrological Information System.

Understanding the Hydrological Information System (HIS)

The Hydrological Information System (HIS) is the backbone of water resource management at ANA. It serves as a centralized platform for collecting, processing, storing, and disseminating hydrological data. This data includes everything from river levels and rainfall measurements to water quality parameters and groundwater levels. The HIS is designed to provide timely and accurate information to support decision-making in various sectors, including agriculture, industry, water supply, and environmental management. The primary goal of the HIS is to ensure that water resources are managed sustainably and efficiently, balancing the needs of different users while protecting the environment.

Key Objectives of the HIS

  1. Data Collection and Integration: The HIS aims to gather hydrological data from a wide range of sources, including telemetric stations, manual gauges, and remote sensing technologies. This data is then integrated into a centralized database, ensuring consistency and accuracy.
  2. Data Quality Control: Maintaining the quality of hydrological data is paramount. The HIS incorporates rigorous quality control procedures to identify and correct errors, ensuring that the data is reliable and trustworthy.
  3. Data Dissemination: A key objective of the HIS is to make hydrological data readily available to the public, researchers, and decision-makers. This is achieved through various portals and products that provide access to data in different formats and levels of detail.
  4. Decision Support: The HIS is designed to support decision-making in water resource management. By providing timely and accurate information, it helps stakeholders make informed decisions about water allocation, drought management, flood control, and other critical issues.
  5. Hydrological Modeling: The HIS supports the development and application of hydrological models. These models are used to simulate hydrological processes, forecast water availability, and assess the impact of different management scenarios.

Specific Portals and Products of ANA's HIS and Their Objectives

ANA's Hydrological Information System is composed of several portals and products, each catering to different user needs and objectives. Here's a breakdown of some key components:
