Typically, water has been allocated by some priority criteria like water rights in each country . However, water allocation by priority might have the problem in which the area of lowest priority can suffer from water shortage all the time. So, this study has tried to develop water allocation rules by weighting factor techniques. The weighting factors are estimated by sectoral and regional factors. The Analytic Hierarchy Process (AHP) is applied to estimate the sectoral factors and the regional factors can be divided by the regional-characteristic and regional-scale ends. The water allocation rules for the reservoir are developed by applying those weighting factors and the rules are applied to Andong dam reservoir which supplies the water to Busan-Si, Daegu-Si, and Goryeong-Gun, Korea in water deficit situation. As a result, all sectors and regions could share the burdens of water shortage by the water allocation using the relative weighting factors.

Relative Weighting

The analytic hierarchy process has been used to evaluate and prioritize decision criteria for over 25 years. This case examines an application of the process to a source selection problem in an environment with several stakeholder organizations with disparate assessments of the relative weighting of various decision criteria. The process served as an effective way to establish consensus and produce a supportable decision model.

Summary Multiple 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).

This study deals with the assessment and mapping of neotectonic landscape deformation in the northern part of the Evia Island (Central Greece). Multi-Criteria Decision Analysis (MCDA) utilizing Analytic Hierarchy Process (AHP) and Weighted Linear Combination (WLC) procedures were conducted for the calculation of the Neotectonic Landscape Deformation Index (NLDI). The study is based on the combination of morphotectonic, geomorphological and geological parameters. The GIS-based spatial MCDA led to the classification of the study area into five classes of neotectonic deformation (from very low to very high) and to a neotectonic deformation map. The results were compared with the outputs of a relative tectonic activity classification approach based on quantitative geomorphic analysis at a regional scale, including site-specific field observations. Areas of high and very high deformation are related to the major active faults of Dirfis, Kandili and Gregolimano–Telethrio. Other minor active normal faults of medium to high seismic risk level, affecting the northern and northeastern parts of the island, are also associated with areas of intense landscape neotectonic deformation.
