The purpose of the modern watershed study is to use a regional pilot to select an erosion sub-basin and restore it to preserve the downstream wetland. In this research, Alanza watershed, located in the upstream reaches of Anzali wetland, has been selected as a sub-watershed (pilot) with the aim of investigating the effect of mechanical, biological and biomechanical operations on modern watersheds. At first, the location of the construction of the watersheds was determined using field operations. Then, due to the planting of species, structural design and also to study the current status of the flow in the river flow modelling channel, using flow and sediment modelling software (HEC-RAS) was used. Using the HEC-Geo RAS extension in the GIS software, the spatial data related to the shape of the river and its longitudinal slope were entered into the HEC-RAS software, and flood flows analysis was calculated. Then, for the design of the structure, the highest score was assigned to the coverage of a mortar coating with a score of 36. Due to the climatic, ecological and environmental conditions of Alanzeh sub watershed for seedling of several forest species, seedlings with ecological conditions of the study area were used.
