This study investigates the recurring floods within the Nekor Basin of NE Morocco, a phenomenon dating back to 1944. A multitude of factors has contributed to these recurrent floods, which profoundly affect the northern region encompassing the Nekor Plain. The research primarily investigates the influence of specific weather conditions on the surge of water levels in “Wadi Nekor” and the ensuing consequences when the valley veers from its primary course. The research findings strongly indicate that a significant portion of these flood events can be attributed to “Cut-Off Low” (COL) and atmospheric rivers (ARs), frequently aligning with mean sea level pressure (MSLP) systems located over, or in proximity to, the Moroccan region. This study employs a systematic classification and arrangement methodology for both upper and lower atmospheric levels in analyzing pertinent cases.
