Insofar as they reduce water availability and condition agricultural and industrial uses, EF represent a constraint, but they also hold out new opportunities for development. This study focuses on the final stretch of the Ebro River (Spain) and on the competing environmental uses of water (the Ebro Delta is a biosphere reserve) and economic uses (irrigation and electricity generating). Environmental flows in the Ebro Delta are currently managed only from the Mequinenza dam and reservoir in eastern Aragon, and the resulting outflows have more than once driven the level of the reservoir down to critical environmental levels in recent years. In general, this management policy has also caused a range of negative environmental and economic impacts in the area. However, other alternatives exist, which could foster both more cooperative and equitable flow allocations, and the development and sustainability of the Ebro Basin. To this end, we develop a water management model to simulate scarcity scenarios and measure the associated environmental flow default rates assuming current productive uses. Our findings confirm that it is not possible to guarantee EFs in the delta without reservoir-based water management so as to ensure the compatibility of EFs with the irrigation and hydroelectric activities. Moreover, the existence of more equitable and cooperative water management options would reduce water pressures on Mequinenza dam and so help fulfill the subsidized irrigation commitments established in Aragonese Lower Ebro Plan. 000078321 536__ $$9info:eu-repo/grantAgreement/ES/DGA-FEDER/S10$$9info:eu-repo/grantAgreement/ES/MEC/FPU14-01694$$9info:eu-repo/grantAgreement/ES/MINECO/ECO2013-41353-P 000078321 540__ $$9info:eu-repo/semantics/openAccess$$aby-nc-nd$$uhttp://creativecommons.org/licenses/by-nc-nd/3.0/es/ 000078321 590__ $$a6.395$$b2018 000078321 591__ $$aENGINEERING, ENVIRONMENTAL$$b8 / 52 = 0.154$$c2018$$dQ1$$eT1 000078321 591__ $$aGREEN & SUSTAINABLE SCIENCE & TECHNOLOGY$$b6 / 35 = 0.171$$c2018$$dQ1$$eT1 000078321 591__ $$aENVIRONMENTAL SCIENCES$$b18 / 250 = 0.072$$c2018$$dQ1$$eT1 000078321 592__ $$a1.62$$b2018 000078321 593__ $$aEnvironmental Science (miscellaneous)$$c2018$$dQ1 000078321 593__ $$aStrategy and Management$$c2018$$dQ1 000078321 593__ $$aRenewable Energy, Sustainability and the Environment$$c2018$$dQ1 000078321 593__ $$aIndustrial and Manufacturing Engineering$$c2018$$dQ1 000078321 655_4 $$ainfo:eu-repo/semantics/article$$vinfo:eu-repo/semantics/acceptedVersion 000078321 700__ $$0(orcid)0000-0001-9521-4156$$aSánchez-Chóliz, J.$$uUniversidad de Zaragoza 000078321 700__ $$0(orcid)0000-0003-4802-600X$$aSarasa, C.$$uUniversidad de Zaragoza 000078321 7102_ $$14000$$2415$$aUniversidad de Zaragoza$$bDpto.
