Specifically, the area of ​​the Segura river basin is defined in Article 2.2 of Royal Decree 125/2007 of 2 February, which establishes the territorial scope of hydrographic demarcations:

"Includes the territory of watersheds that flow into the Mediterranean Sea between the mouth of the Almanzora River and the left bank of the Gola del Segura at its mouth, including its transition waters; Also the hydrographic sub-basin of the Rambla de Canales and the endorheic basins of Yecla and Corral Rubio. Coastal waters have as their southern boundary the line with a 122º orientation that passes through the Pozo de los Mones, north of the mouth of the Almanzora River, and as a north boundary the line with a 100º orientation that crosses the coastal boundary between the municipalities of Elche and Guardamar del Segura ".

 

Likewise, on the surface of the Segura hydrographic demarcation, 14 hydraulic zones have been differentiated, taking into account hydrographic, administrative, socio-economic and environmental criteria. The following table shows the different hydraulic zones that form the zoning of the territory of the hydrographic demarcation for surface waters.
