Automatic hydrological information system for Hidrosur

The Hidrosur SAIH (Automatic Hydrological Data Collection System) Network is a set of remote stations strategically distributed to gather, in real time, information on hydro-meteorological incidents.

The aim is to take the appropriate measures, both in anticipation of forthcoming flood scenarios, as well as in the development of water resources.

The measurements in the stations are made by sensors. These are measurements of hydro-meteorological parameters (water levels, flow rates, rainfall, weather, meteorological stations, gate position sensors, storm detectors, etc ...), as well as parameters necessary to verify the proper functioning and safety of the actual centres.

In particular, the Hidrosur Network covers the Andalusian intra-community basins, such as the Mediterranean basins, the Guadalete, Barbate, Tinto, Odiel, Piedras and Chanza. It extends through the provinces of Huelva, Cadiz, Malaga, Granada and Almería.


All the data coming from the stations is transmitted to the Control Centre stationed in Malaga. There, the software tools responsible for collecting, validating, viewing and analysing the information gathered are stored.

It has been equipped with a Decision Support System (SAD), consisting of a set of hydro-meteorological models and computer tools designed to simulate the current and future hydrological behaviour of the basin, whose purpose is to support the management of Operations Systems in flood scenarios to reduce the magnitude of it and advance as much as possible the notices to Civil Protection should floods occur, as to minimise damage.

Ayesa, as part of a Joint Venture with Ofiteco, currently provides the service of Maintenance, Operations and Technological Renewal of the Network. This service ensures the perfect functioning of the SAIH, that is, the conservation and maintenance of all the elements of the system and the exploitation of the generated information.

Regarding the System's running, this must handle its operations and perform the daily monitoring of the data received, its classification and distribution to authorised users, as well as the drafting of reports on operations affecting resources and floods produced.

Amongst other tasks, the following works have been carried out:

  • Preventive and corrective field maintenance of all Remote Stations, associated instrumentation and communication systems
  • Annual campaigns of batteries and rectifiers, adaptation of communication towers and maintenance of civil works
  • Maintenance of the Control Centre, including the maintenance of all equipment, networks, generic and specific software, administration of the database, the operation of all of these and the installed applications, as well as the updating of the software versions.
  • Renewal of equipment due to depletion, obsolescence or discontinuity in manufacturing

Current challenges and Ayesa's solutions

Major infrastructures must respond to new demands relating to connectivity, brought about by new technology and digitalisation, as this is the only way to increase the number of people living in sustainable cities. Since market globalisation and instant communication have completely changed consumer requirements, companies must now rise to the challenge of adapting their production processes to their demands, ranging from transport and supply improvements to more efficient homes and workplaces. That’s where smart factories come in, offering optimisation, production flexibility, increasingly smaller batches and product customisation. And this is only possible with interconnectivity and digitalisation.

Nowadays, we suffer from information overload. That is why applying intelligence to data is crucial to drive companies forward. Combining big data with the flexible, scalable and agile cloud results in a powerful tool that gives companies a competitive edge. Both information storage and cloud services help companies focus on what really matters—their core business—with reduced costs. However, interconnecting multiple decentralised information points poses new risks and threats. Ayesa’s focus on engineering, technology and consulting (ETC) puts us in the best position to bring intelligence to infrastructures, as well as optimise their operation and maintenance. We can offer a wide range of responses to the challenges of creating a smarter city (transport solutions, sustainable buildings, smart leisure, etc.). We have an overall vision of Industry 4.0 requirements: engineers specialised in processes; process automation, robotisation and optimisation; and expertise in business interconnection and applying intelligence. We have a team of multidisciplinary experts to guarantee the success of artificial intelligence deployments. At Ayesa, we accompany organisations as they introduce cloud solutions, helping them decide which steps to take and offering superscalar solutions. We have over 10 years’ experience working on the design and implementation of hybrid cloud solutions. We also perform jobs that fall under ethical hacking and we conduct cybersecurity audits in both IT and OT. What's more, as specialists in industrial cybersecurity, we perform diagnostics and forensic analyses.

Our expertise and technology

We can optimise your skills, tools and technology with our ETC approach. Our aim is to bring about the full digital transformation of services, entities and companies.
As specialists in the digitalisation of transport infrastructure, we use the latest technology (AR, BIM, AI, IoT, blockchain, BI, etc.) to develop technological platforms for management and maintenance. This includes everything from diagnostics systems to mobile apps for users.
Urban intelligence
We offer a wide range of smart solutions for towns and cities. As such, we provide transport solutions, such as fleet tracking, electric vehicle (EV) charging, smart building management, and digitalisation of water and power supplies.
Ayesa Pilot
This is an IoT industrial solution developed by Ayesa. It allows multiple facilities as well as external information sources to be integrated into a single information platform, thereby giving companies a tool to manage their facilities safely, securely and efficiently..
Artificial Intelligence
We have extensive experience in developing and integrating artificial intelligence to optimise service and infrastructure processes in key industries. What sets us apart is our development of algorithms, combined with in-depth knowledge of technologies, systems, service operations and engineering.
Cloud computing
We specialise in deploying solutions in the main public cloud providers (IaaS, PaaS and SaaS). We implement hyper-converged architecture based on hybrid cloud and multicloud environments, combining data storage, IT resources and networking to become a data centre as a service (DCaaS). As such, we are experts in deploying advanced architectures in the cloud.
As specialists in cybersecurity services in IT and OT environments, we adapt to our clients’ requirements. We design, define and implement secure infrastructure, perform diagnostics and forensic analysis in IT/OT environments, provide technical and regulatory consulting and advice, conduct static (SAST) and dynamic testing (DAST), and assess the status of infrastructure.
