英文摘要	The objective of the study was to verify the applicability of P-k-C* model to evaluate the treatment response of horizontal CWs (H-CWs) and to assess key design parameters for the model optimization in Mediterranean climate conditions. The experimental study was carried out in 4H-CWs located in the province of Catania (Eastern Sicily, Italy). The parameters P, k(A20 )and theta were optimized to minimize the sum of the square of the errors (SSE) between observed and modeled outlet concentrations for COD, BOD5 and NO3- quality parameters. Once the minimization process was carried out by an iterative, nonlinear procedure, then data were divided into calibration and validation sets for each CW. The calibration was set by fixing a P value from the literature range and varying k(A20 )and theta and then by using the obtained values of k(A20 )and theta and by varying P. This procedure was repeated until two successive P calibrated values differed less than 2%. The performance of the model was very good in most of the cases, as also evaluated in terms of R2, NSE and RMSE. In particular, considering the three investigated pollutants, the calculated k(A20 )values were generally higher than those from CWs located in temperate climate zone (65-157.1 m year(-1)), while the theta values were slightly lower than 1 (0.88-0.91). This study can be considered a first contribute for P-k-C* model application in semi-arid regions characterized by Mediterranean weather conditions.
