The Watershed Management Sub-Committee Joint Pilot Activity (JPA) for Mountainous Erosion Control in Alenze Sub-Basin of Masal River Basin ended on 18th September 2017.
The JPA is an activity to control erosion in a mountainous area within Anzali Wetland Basin to contribute to the Wetland conservation by reducing the amount of sediment flowing into the wetland.
The integrated study for this project was done in 2015, followed by a detailed design survey in 2016. The implementation of this construction work started at the beginning of May 2017 and after about 5 months the construction work was completed in September 2017. The construction work is composed of two areas 1) Mountainous Stream Area and 2) Mountainous Slope Area. A combination of gabion wall, water channel, contour line and ford crossing structures were constructed as effective measures for erosion and sediment control at the stream area in addition to a series of terraces covered by soil bags, fencing and enclosing for recovering the vegetation and reducing erosion at the slope area.
The shared technology through this JPA contributes to the capacity development of related organizations, especially Natural Resources and Watershed Management General Office (NRWGO), which has the responsibility to control erosion and sediment in mountainous areas.
The attendants of the closing ceremony were Mr. Mohamadi, from Forest, Rangelands and Watershed management Organization, Mr. Yamazaki, from Japan International Cooperation Agency (JICA) Iran Office, Mr. Aoki and Mr. Imai, from JICA Expert Team (JET) of the Anzali Wetland Project and experts from Gilan NRWGO, Gilan Ministry of Jihad Agriculture, Gilan Religion Water Company, Masal NRWGO and Gilan Department of Environment Office.
JICA Expert Team hopes strongly that the shared Japanese technology by the JPA including construction management system will be utilized for further activities which will be implemented by the related organizations and will contribute to wetland and mountain conservation in Iran.
The Iranian side is planning to continue the second phase of this JPA in 2018 by using the same study and management methodology.
