CEDEX

CEDEX is the centre for public works studies and experimentation. It is a cutting-edge public body in the field of public works, mobility, inland and marine waters, the environment and climate change. It is attached to the Ministry of Transport and Sustainable Mobility, which also reports to the Ministry for Ecological Transition and Demographic Challenge.

CEDEX is divided into eight specialised technical units called Centres and Laboratories. From each centre, CEDEX provides high-level technical assistance, carries out applied research and technological development, and transfers knowledge through courses, conferences and seminars. Of the eight centres, the Centre for Hydrographic Studies stands out, providing the climate data necessary for this project.

Its functions include the evaluation and certification of materials and techniques, the development of standards and regulations, and the promotion of R&D&I projects in line with national and European plans. In addition, it provides specialised technical assistance to administrations and private entities, collaborates in the conservation of infrastructure heritage, and promotes knowledge transfer through publications, courses and technical meetings. It also promotes national and international cooperation in the scientific-technical field and, in certain cases, acts as an arbitrator in disputes related to its area of competence.

API

CEDEX has a large amount of data available on its website. As such, it does not have an API for accessing the data. The data is fully accessible from the website itself.

Among the available data, CEDEX presents eight different databases, each covering a different area of those described above. The databases are as follows:

  • Environmental Restoration Portal

  • Capacity Yearbook

  • Noise Mapping System

  • Coast and Sea Information System (INFOMAR)

  • Spanish Precipitation Isotope Monitoring Network (REVIP)

  • Spanish Water Information System (Hispagua)

  • Catalogue of waste materials that can be used in construction

The database of interest for the project is the Flow Measurement Yearbook. This database is an official publication that compiles daily, monthly and annual data on flow rates measured at river and reservoir gauging stations.

It includes hydrological records such as:

  • Average daily, monthly and annual flow rates.

  • Precipitation and inflows in the basins.

  • Information on the measuring stations (location, technical characteristics, etc.).

  • Evapotranspiration data such as temperature and precipitation.

The data files are divided by each basin organisation. Among them is the Júcar Hydrographic Conference (CHJ), which has all the data on the reservoirs and the Júcar River, which is the basin of interest for the project.

The update times are not defined on the website. The time range covered by the data is from the last century to a few years ago. Depending on the dataset downloaded, the time span is different. For example, for the CHJ data, specifically the daily data files on reservoirs, canals, rivers and evaporation, the time span is different.
