Hydrological planning cycle 2021–2027 Hydrological Plans as an instrument for the achievement of the Environmental Goals of water bodies. Hydrographic Demarcation of the Andalusian Mediterranean Basins Málaga, September 3rd 2019 Andalusia Regional Government has full competence in the planning of 3 intra-Community demarcations: Tinto Odiel Piedras, Guadalete-Barbate and Andalusian Mediterranean Basins. DE LAS CUENCAS MEDITERRÁNEAS ANDALUZAS Andalusian Mediterranean River Basin District Territorial Area of the District Decree 357/2009, of October 20 establishing the territorial area of hydrographic districts of the intracommunity basins located in Andalucía Region Andalusian Mediterranean River Basin District Hydrologic Planning Process Andalusian Mediterranean River Basin District Domestic legislation Art. 126 bis Regulation for the Hydraulic Public Property (“ Reglamento de Dominio Publico Hidráulico”) 1) The hydraulical administration will promote the respect for longitudinal and lateral continuity of the river courses making them compatible with current uses and existing infrastructures. 2) It shall require the installation and maintenance of devices ensuring the passage of native ichthyofauna autóctona. 3) In the defense works against floods will take into account the continuity of the riverbed. 4) It will promote the elimination of abandoned Hydraulic Public infrastructures without fulfilling any function linked to water use.. 5) It will take into account possible conditions for the transport of sediments in the granting of new transversal works. Andalusian Mediterranean River Basin District Categorization of Bodies of Water type River The bodies of water in the river category have been classified into the following four types collected by the Water Planning Instruction for the internal Andalusian basins ("Instrucción de planificacion hidrologica cuencas internas andaluzas IPHA") • Permanent rivers • Temporary or seasonal rivers • Intermittent or strongly seasonal rivers • Ephemeral Rivers Andalucian Mediterranean River Basin District ECOLOGICAL FLOWS • The ecological flow regime is the tool that contributes to the good condition or good ecological potential in rivers or transitional waters respectively, because due to the problem arising from water scarcity, it becomes essential establish a restriction on the use of the water resource, with the aim of maintaining the functionality of ecosystems, avoiding their deterioration.. • The minimum flow rate regime has been established in all DHCMA water bodies, with particular interest in those bodies of water where compliance with this flow regime could conflict with other uses.

Andalusian Mediterranean River Basin District Case Study Pilot Study for Hydrological Ordination in River Valleys “Grande de Bérchules” and “Mecina” 1. Why this project comes up? Need to give an answer as much complete as possible to the current concern related to the management of the water resource detected in "La Alpujarra" region: -year-on-year variable rainfall regime, -strong agricultural activity in the most fertile soil areas with irrigated crops during the summer period, Beans Tomato Mosaic of crops 1. Why this project comes up? -steep orography and high slopes: erosion, high speeds, loss of fertile soil. - incomparable ethnographic value in which the network of ditches stands out as a key element in the equation of watershed hydrogeology, 1. . Why this project comes up? -needs of the local population: water supply and irrigation - climate change scenarios augur a reduction in rainfall in both rain and snow forms and an increase in temperature.. 1. Why this project comes up? - ecological singularity: mountain grassland, riverside vegetation, sheep, chestnut trees, endemism, common trout, etc. -competition for the water resource: hydropower, ecological flows, irrigation, etc. EXISTENCE OF DRY STRETCHES THE SCIENTIFIC COMPONENT: KNOWLEDGE AND DATA COLLECTION Characterization of rafts Raft inventory Review of water use files Irrigation surfaces Processing of the Sierra Nevada Natural Area's summer flow control campaign Flow control network Soil moisture and radiation control points THE SCIENTIFIC COMPONENT: VEGETATION WATER NEEDS Using satellite images, the daily water consumption of the different plant covers has been estimated in the municipal terms of Bérchules and Alpujarra de la Sierra (Granada) during the 2013/2014 campaign. This information was integrated into the integral model of the basin Sensor OLI-Landsat 8 Campaign 2013/2014 11 August 2013 12 September 2013 Calibrated and atmospherically corrected 15 November 2013 19 February 2014 23 March 2014 8 April 2014 24 April 2014 10 May 2014 26 May 2014 27 June 2014 13 July 2014 29 July 2014 15 September 2014 24 April 2014 29 July 2014 THE PARTICIPATORY COMPONENT: CONDUCTING WORKSHOPS Whenever people with different goals and resources satisfactorily manage a problem in which everyone has an interest always happens social learning: learning together to manage together.
