SALINE WATER INGRESSION IN UPPER PART OF BALESWAR RIVER NEAR NAZIRPUR UNDER PIROJPUR DISTRICT: A CASE STUDY

A five year project was undertaken to address the salinity problem in upstream of Baleswar river. The information generated during this period have been presented paper. Previously Madhumati-Baleswar river system completely non saline throughout year. Recently fresh water flow from Madhumati through passing between Chitalmari and Nazirpur Upazila is about cease due prolonged siltation on bed. During intensive monitoring work (1995-1999) some canals such as Chitra river, Vasa canal, Santoshpur Lara canal etc. are identified portals dry season. Due tidal effect they carried Daratana As a result high prevailed February May. Maximum ECw 17.6 dS/m soil ECe 4.4 were recorded Water extraction for irrigation riparian area restricted salinity. To minimize has be increased. Increased volume will push back downward direction. major namely may closed seasonally by constructing sluice gate with proper engineering design prevent entry
