Recent studies have proven the importance and functionality of phase space reconstruction model based on the delay time approach. The main scope in this research is to develop the phase space in order to analyse and describe the event along with. The flow discharge of Band-bahman station in daily, weekly and monthly scale between 1348 and 1385 have been considered. The embedding dimension has been calculated 3 based on the simplistic method first. Then the phase space have been developed using the time delay approach. Results indicate less chaotic manner for daily data according to cloudy trajectories of the phase space. Monthly and weekly flow time series indicate more chaotic manner. According to phase space analysis there have been 5 very heavy one day raining at Band-bahman station and 12 very heavy one day raining at basin could be distinguished. Besides, 6 intensive heavy raining with one week durability at the station and 11 at the basin are pointed. The river flow discharge have been varied between 0 to 140 cubic meter per second for daily scale, 1.5 to 60 cubic meter per second for weekly scale and 1 to 23 cubic meter per second for monthly scale data series.
