| In the analysis of the relationships between precipitation, flow and erosion events, large and important events that occur with a relatively long return period have a very high contribution to the sedimentation of the entire watershed. Today, the analysis of these events and their mutual behavior has been the focus of researchers. Dehgin representative and paired watershed is one of twelve representative and paired watersheds of the country, which are designed and equipped with the aim of obtaining basic hydrological data and other data needed for watershed management and also evaluating watershed management operations. However, comprehensive study has not been done to analyze and evaluate the quantity and quality of monitored data and data mining of climatic data, flow and soil erosion. In this research, while introducing precipitation extreme events, their impact on flow and soil erosion values in sample and control sub-watersheds of Dehgin watershed were compared. The results showed that data sufficiency in climate and flow monitoring units made it possible to provide a suitable and competent analysis of simultaneous rainfall and flow data as well as the comparison of control and sample sub-watersheds. Also, in the relevant rainfall and erosion events, clear and valuable analyzes of the difference in the behavior of the sample and control sub-watersheds can be observed against rainfall events. But the investigation of erosion and flow in the mentioned sub-watersheds was faced with few comparable scenarios. This shows that with the continuation of data collection in the long term, generalizable data can be obtained from this representative watershed for hydrological modeling in the watershed. In this watershed, extreme flow events have more consistency with higher intensity rainfall events with about 70% overlap in terms of time and quantitative ranking, but most of the extreme erosion events follow the maximum values of rainfall quantity. | ||
