help and support granted would serve as a base to determine if the application of those resources was efficient. The construction of performance indicators would be appreciated for future analysis and future use of the damages—support—effects relationship. For example, Jiménez [18] shows methodological guides for the construction of indicators, defining them as a tool that offers quantitative information with respect to achievements of results in the delivery of products or services generated by the institution, covering both quantitative and qualitative aspects. Also, historical water demand data and its relationship to drought declaratives need to be analyzed. In the forensic analysis, even paleoclimatology studies can be considered, such as tree ring studies that can offer

**•** Integration of analysis and objective establishments of causes: In this phase, the integra‐ tion must classify each variable and factor analyzes, giving them the adequate weight. Based on all analysis performed, an integral model with matrix array for the evaluation of categories, variables and factors in a weighted form can be implemented. The results of the model may show two groups, historical trend if it exists, and the causes directly associated to the event under study. Once the causes that favoured or increased the impacts of the phenomena have been determined, the making of a simplified tree diagram can be built. This tree will show the main causes, asking and answering in a very concise and objective manner the why's and what's. This will converge to the main cause of the disaster and to the actions that should be taken immediately. Also it will establish the strategies to be followed in order to reduce the impacts of this phenomenon in the region

**•** Integral actions: The final report should include (a) prioritized causes, (b) lessons learned, (c) actions and recommendations for the immediate time and short and medium terms, (d) critical elements for prevention and preparation in case of droughts and (e) funda‐ mental cultural elements to be implemented so the lessons would become effectively lessons learned in the emergency management. Inclusive vision should be taken as seriously as possible. More than a policy that must be adopted, it will be an action that should be implemented. No stakeholder or decision maker should be excluded. Just remember that drought is a phenomenon that is not scale selective, nor sectorial. It affects big spaces and affects the least resilient systems. Integrative actions favoured by drought forensic analysis should include the institutional, methodological, public and operational parts, so they allow success in the face of a new event. Inclusive vision considers, for example, investments in monitoring and early warning systems, implementation of prevention and mitigation programs, legal framework strengthening, institutional coordination, capacity building, communication and of course research. It is well known that something that can be measured, can be improved, so evaluation and action updating as well as adaptive capacity towards resilience represent step to success. Those are the

type of things drought forensic analysis is seeking.

under study.

Forensic analysis in hydrology can provide the necessary and sufficient information for the authorities and decision makers to establish programs of attention and control of these phenomena in the future elements. Though this to some extent has been given, it is desirable that the process rests on objective technical reports based.

It seems obvious to say that the issues in which forensic hydrology can be applied are numer‐ ous and varied. Cases of floods and droughts are perhaps the most evident, especially urban pressure that every day affects the ability of natural streams that drain a basin or a cultivated area.

As a result of all this, forensic hydrologists, a specialty with a great future, can apply a large number of technical tools in order to make detailed studies on the precise causes of a disaster. From our ability to select, the best forensic techniques depend largely harm reduction or the safety of our sources of supply.

The results of forensic analysis in hydrology effectively contribute in the search for better alternative solutions to recurring problems in all our countries.
