- Conflicts and resolutions in managing water allocation at the watershed scalePublication . Srdjevic, Zorica; Srdjevic, Bojan; Melo, Paulo; Jorge, LuísaMultiple runs of a river basin model produced information about water allocation under different users’ priorities, creating a set of allocation scenarios as possible decision alternatives. To identify the most desired scenario that will, expectedly, be more readily accepted and implemented, involvement of stakeholders and reaching the consensus among them in evaluating scenarios are essential. This article describes methodology for integrating multi-criteria optimization as an efficient tool for the evaluation of scenarios in a group context, with river basin simulation-optimization models. Methodology was developed within the scope of the bilateral project Serbia–Portugal, and it consisted of five phases: defining the preference schemes of allocation, running the ACQUANET model, evaluating the criteria and strategies with analytic hierarchy process, aggregation and initial search for consensus in subgroups, and obtaining the final consensus converged result (best management strategy). The approach was tested on the water allocation problem in the Nadela watershed in Vojvodina Province in Serbia, with participation of 23 stakeholders. Promising results recommended the approach for the testing in different conditions in the area near Bragança in northeast Portugal (Sabor watershed).
- Water allocation for agricultural users based on multi criteria analysis and use of decision-making toolsPublication . Srdjevic, Bojan; Melo, Paulo; Srdjevic, Zorica; Jorge, Luisa; Zoranovic, TihomirRecent research has signaled promising options to create a unique framework to integrate multi-criteria optimization tools with river basin simulation-optimization models. From the multi-criteria decision-making area Analytic hierarchy process (AHP) is selected to evaluate selected parts of output generated by the river basin simulation-optimization model (ACQUANET) which is applied to allocate water to agricultural users within a given river basin. Multiple runs of a river basin model can produce information about water allocation under different prioritization of users, namely a set of allocation scenarios as possible decision alternatives. The analytic hierarchy process can then be used to efficiently perform the evaluation of scenarios in both individual and group contexts, the latter being especially important because stakeholders’ involvement and participation in making decisions is ‘a must’ in modern decisions. A pilot test of the proposed approach was performed for one hydro-system in Serbia. Another pilot test is under preparation in Portugal and will serve as a verification of the methodology briefly described in this paper.
