A comprehensive analysis of hydrological conditions in a river basin, focusing on the temporal and spatial distribution of water, is essential for understanding the complex interactions and dynamics of water resources. This knowledge forms the basis for effective water resource management and enables the assessment of distribution patterns. Such analysis is key to developing more efficient water management strategies, which are essential for the sustainable use of water resources. The Keritis catchment is an important source for the Chania region as it plays a crucial role in meeting the water needs for irrigation and domestic use. In this study, the WEAP (Water Evaluation and Planning) model was applied to evaluate both the water distribution patterns and the hydrological conditions in the Keritis catchment for the period 2013–2020. Although WEAP is primarily designed to analyze water allocation, due to the lack of detailed hydrological parameters, it was also used to simulate streamflow and total runoff using a simplified rainfall-runoff method. The simulated runoff results were compared with reference values from the literature and showed a satisfactory correlation with the performance indicators: NSE = 0.57, RSR = 0.65 and R² = 0.74. These results indicate that the simplified rainfall-runoff method adequately reflects the variability of runoff in the catchment. In addition, the assessment of water allocation patterns revealed that the existing allocation system effectively met all water demand during the study period and there were no instances of unmet demand. While the simplified rainfall-runoff method captures the general runoff trends, it does not simulate deep percolation or groundwater-surface water interactions in sufficient detail to fully represent the hydrological complexity of the catchment.
