Regional water resource management plans include various scenarios related to the anomalies and trends of hydro-climatic parameters. Two methods are used for the identification of the anomalies and trends associated with high flow (annual and seasonal) of the rivers in Eastern Romania, namely the quantile perturbation method (QPM) and the partial trend method (PMT). These methods were selected due to the fact that they are suitable for data sets which do not rely on restrictive statistical assumption as common parametric and nonparametric trend tests do. For six of the nine stations analyzed, the decreasing trend in high extremes for annual high flow based on the PTM is the same as the annual trend obtained with the QPM. Using the PI index (associated with PTM) for the estimation of trend intensity, values between −2.280 and −9.015 m³/s were calculated for the decreasing trend of the annual high flow and between +1,633 m³/s (in autumn) and −9.940 m³/s (in summer) for the seasonal high flow. The results obtained on the anomalies and trends of high river flow may represent a starting point in the analysis of the evolution of water resources and their effective management.

区域水资源管理计划包括与水文气候参数异常和趋势有关的各种情景。罗马尼亚东部地区有两种方法用于识别与河流高流量（年度和季节性）有关的异常和趋势，即分位数扰动法（QPM）和局部趋势法（PMT）。选择这些方法是因为它们适用于不像一般参数和非参数趋势检验那样依赖于限制性统计假设的数据集。对于分析的九个站点中的六个，基于PTM的年度高流量的极端值下降趋势与QPM获得的年度趋势相同。使用PI指数（与PTM关联）估计趋势强度，其值在-2.280和-9.015 m之间³ / s的计算年度高流量的减少趋势，1633米之间³ /秒（在秋季）和-9.940米³ /秒（在夏天），用于季节性高流动。从河流高流量的异常和趋势获得的结果可能是分析水资源演变及其有效管理的起点。
