SYSTEM STUDY OF SUNKOSI-KAMALA INTER - BASIN WATER - TRANSFER SCHEME (NEPAL)

Abstract

Inter -basin water transfer concept emerged in the field of water resources planning and management is to correct the natural imbalance leading to largely inequitable distribution of water-resources over the vicinity from surplus water area to water deficit area. Nepal's Trai land between Gandhak and Kosi rivers basins, is water deficit land. The majors rivers flowing in this land area, are Kamala and Bagmati rivers which are monsoon fed with discharge in non-monsoon season becoming inadequate to meet the basin demands . Mainly because of this reason, the existing irrigation projects in these basins are water deficit. [Rehabilitation and modernization of the existing projects and further extension of irrigation activities for year round irrigation in these basins have become critical to any further development above the present unsatisfactory low level. The concept of inter basin water transfer applies here to correct the natural imbalance of water distribution] This dissertation study deals with the Sunkosi Kamala inter-basin water transfer scheme. The present trend of water resources development and previous feasibility studies of Sunkosi diversion, suggest the possibility of Sunkosi Kamala inter-basin water transfer scheme....
