Supply, installation and start-up of compact integrated hydrological stations in the stations of Barbadillo del Pez (Burgos), Otero de Guardo (Palencia) and Tardesillas (Soria)
The Duero International Hydrographic Demarcation is the most extensive in the Iberian Peninsula with 98,073 km2, comprises the territory of the river basin of the Duero river as well as the transition waters of the estuary of Porto and associated Atlantic coasts. It is a shared territory between Portugal (20% of the total area) and Spain (80%). The Spanish part of the Duero demarcation covers 78,859 km2. The Spanish part of the Douro demarcation is bordered by the north – west with the Miño – Sil demarcation, by the north by the Cantabrian, by the north – east and by the Ebro, and by the south by the Tagus River; Towards the west the basin continues with Portugal. In Spain the basin extends to the autonomous communities of Castile and Leon, Galicia, Cantabria, Castilla – La Mancha, Extremadura, La Rioja, Madrid and Asturias. In the vast territory described, a drainage network is located that reaches a length of about 83,200 km, of which 13,491 km have been identified as bodies of water. Most of the rivers of the basin have their origin in the mountain ranges that border it and go down to the main axis of the Duero, which along 744 km (in Spain) divides the basin. It differentiates a right or northern margin with two large tributary suburbs, the Pisuerga that includes the Carrión and the Arlanza with the Arlanzón, and the one of the Esla that unfolds in fan to include rivers like Tera, Órbigo, Porma and Cea. The left or southern margin includes smaller rivers that descend from the Central System to the Duero, such as Riaza, Duratón, Cega, Adaja with Eresma, and other smaller ones (Zapardiel, Trabancos, Guareña …). Finally, to the international section, the Tormes, Huebra and Águeda systems directly deliver their waters. The Confederación Hidrográfica del Duero has among its powers the control of the quantity and quality of both surface waters (rivers, streams, lakes and reservoirs) and underground. The Integrated Network SAIH-ROEA is responsible for the continuous and automatic control of the quantity of surface water, which is constituted by 158 flow stations in channels, 174 rain gauges, 38 control points in reservoirs and 48 control points in channels . The 158 stations of flow rates are distributed in 58 river basins, with 16 stations along the Douro River, 9 Pisuerga River, 8 Tormes River, 7 Esla River River and 6 Carrión River Rivers, Eresma, Luna-Órbigo and Arlanzón.
The flow data provided by the Integrated Network S.A.I.H.-R.O.E.A. Serve two main objectives: – Recording of flows through the basin channels to improve the management of water resources, having a special relevance in hydrological planning. – Report in situations of risk of floods and floods to the competent authorities so that they take the decisions they deem appropriate to minimize the risk and, if necessary, the restoration to the normal situation. Starting from the description of the Duero basin and Its hydrological and territorial characteristics, the Hydrographic Demarcation has decided to rely on ARANTEC to extend its integrated network of riverbeds control in 3 significant points of the rivers Pedroso, Besande and Tera.
The first control point, called Barbadillo del Pez because of its location in this town in the province of Burgos, is located on the Pedroso river, affluent on the right bank of the Arlanza River, which as previously mentioned belongs to the Pisuerga basin , Affluent in its turn by the right margin of the Duero. The second control point, called Otero de Guardo, is located in the town of Velilla of the river Carrión on the bridge over the Besandino river, affluent on the right bank of the river Carrión, also belonging to the Pisuerga river basin.
The third control point, called Tardesillas, is located in the town of Tardesillas on the bridge over the Tera River, affluent on the right bank of the Duero River.
In all locations a radar type river level sensor up to 15 m high has been installed, as well as sensors of ambient temperature and relative humidity, fed by photovoltaic plates and communications through GPRS with the Basin Control Center of The Duero Hydrographic Demarcation located in Valladolid. Arantec, has installed these control points in just a few days and has integrated them, even with its own data and alarm management platform, within the interface that owns the Duero Hydrographic Demarcation managed by software called WISKI. This confirms the great speed and flexibility that the teams possess, being able to be integrated within administrations of great importance as the one of the Duero Hydrographic Confederation.
