The North Area of the Gorganrood &Gharesoo Rivers Drainage Project (280,000 ha)

Narrative Description of Project

Following the sustainable development policies, Golestan province water authority has considered preventing desertification and increase of saline soils, salt balance control, flood control of Gorganrood & Gharesoo rivers, modifying existing surface and subsurface drainage systems and development of conventional drainage techniques, bio drainage, controlled drainage, dry drainage, evaporation accelerators, phytoremediation, sequestration carbon, haloculture agro industry, channel improvement, by – pass floodways, flood storage areas, water harvesting, river bank protection, physical, chemical & biological soil reclamation methods in order to improve the social and economic status by increasing the agriculture production in project area, 280000 hectare with the approximate population of 200,000 who inhabit in 4 cities & 300 villages.
