“…The weights are established according to the demand class associated with the indicator, ranging from class A (demand > 100 hm 3 year −1 ) to D (demand < 10 hm 3 year −1 ). The Jucar river basin represents a Mediterranean droughtprone and highly regulated basin, featuring one of the most innovative and effective drought management systems, relying on the formulation of an empirically constructed basinspecific drought index (Andreu et al, 2009;Haro et al, 2014b;Haro-Monteagudo et al, 2017;Carmona et al, 2017). As a consequence, it represents the state of the art for basin-customized operational drought indexes employed for drought-restraining purposes, and a remarkable benchmark to test and validate the proposed FRIDA methodology.…”

“…In such a highly regulated basin with long overyear storage, water scarcity is not a necessary condition derived from a meteorological drought (CHJ, 2007a;Carmona et al, 2017). Thus, traditional drought indexes fail at detecting the timing and severity of the incidence of a drought, and an ad hoc monitoring system was conceived to properly capture the hydrological status of the catchment.…”

“…The potential of the proposed framework is demonstrated by the highly regulated Mediterranean basin of the Jucar river, in eastern Spain, where the state-index-based drought management system provides an ideal benchmark for testing the FRIDA index (Andreu et al, 2009;Haro et al, 2014b;Pedro-Monzonís et al, 2014;Macian-Sorribes and PulidoVelazquez, 2017;Haro-Monteagudo et al, 2017;Carmona et al, 2017). The Jucar state index provides guidelines for the application of FRIDA.…”

“…Each drought management plan and the relative state index formulation is the result of a long collaborative process including public participation, basin experts, and stakeholders, and provides an effective multi-sector partnership approach for managing drought risk (Carmona et al, 2017). State indexes are the result of a long trial-and-error process mostly begun in the 80s, through which the variable choice and combination have been progressively adjusted to best suit the basin drought management requirements.…”

Abstract. Socio-economic costs of drought are progressively increasing worldwide due to undergoing alterations of hydro-meteorological regimes induced by climate change. Although drought management is largely studied in the literature, traditional drought indexes often fail at detecting critical events in highly regulated systems, where natural water availability is conditioned by the operation of water infrastructures such as dams, diversions, and pumping wells. Here, ad hoc index formulations are usually adopted based on empirical combinations of several, supposed-to-be significant, hydro-meteorological variables. These customized formulations, however, while effective in the design basin, can hardly be generalized and transferred to different contexts. In this study, we contribute FRIDA (FRamework for Index-based Drought Analysis), a novel framework for the automatic design of basin-customized drought indexes. In contrast to ad hoc empirical approaches, FRIDA is fully automated, generalizable, and portable across different basins. FRIDA builds an index representing a surrogate of the drought conditions of the basin, computed by combining all the relevant available information about the water circulating in the system identified by means of a feature extraction algorithm. We used the Wrapper for Quasi-Equally Informative Subset Selection (W-QEISS), which features a multi-objective evolutionary algorithm to find Pareto-efficient subsets of variables by maximizing the wrapper accuracy, minimizing the number of selected variables, and optimizing relevance and redundancy of the subset. The preferred variable subset is selected among the efficient solutions and used to formulate the final index according to alternative model structures. We apply FRIDA to the case study of the Jucar river basin (Spain), a drought-prone and highly regulated Mediterranean water resource system, where an advanced drought management plan relying on the formulation of an ad hoc "state index" is used for triggering drought management measures. The state index was constructed empirically with a trial-and-error process begun in the 1980s and finalized in 2007, guided by the experts from the Confederación Hidrográfica del Júcar (CHJ). Our results show that the automated variable selection outcomes align with CHJ's 25-year-long empirical refinement. In addition, the resultant FRIDA index outperforms the official State Index in terms of accuracy in reproducing the target variable and cardinality of the selected inputs set.

“…The variables and weights are chosen in order to obtain an integrated 110 indicator representative of the hydrological status in each river basin (Estrela and Vargas, 2012). The value of the State Index is monitored monthly and used to trigger water demand and supply measures when entering a drought period according to the Drought Management Plans (DMPs) established in each Spanish river basin district (Garrote et al, 2007;Gómez and Blanco, 2012;Haro et al, 2014a) as a result of a long collaborative process including public participation, and providing an effective 115 multi-sector partnership approach for managing drought risk (Carmona et al, 2017).…”
