TAILIEUCHUNG - A study on impact of climate change to salinity at water intake points of supply water factories and adaptation solutions proposal
The paper presents a research on impact of climate change to salinity at water intake points of supply water factories and proposes adapting solution. In the research, the change precipitation induced flow as well as the change of discharge of reservoirs flow according to climate change scenarios are calculated by NAM and regulation of reservoirs models. | Journal of Science and Technology 54 (4B) (2016) 116-122 A STUDY ON IMPACT OF CLIMATE CHANGE TO SALINITY AT WATER INTAKE POINTS OF SUPPLY WATER FACTORIES AND ADAPTATION SOLUTIONS PROPOSAL Ky Phung Nguyen1, *, Kim Tran Thi2, Nguyen Thi Hang3, Bay Nguyen Thi4 1 Department of Science and Technology, HCMC. 244 Dien Bien Phu Street, Ward 7, District 3, HCMC 2 3 4 HCM University of Natural resources and Environment. 236B Le Van Sy Street, Ward 1,Tan Binh District, HCMC Industrial University of HCMC. 12 Nguyen Van Bao street, Ward 4, Go Vap District, HCMC University of Technology – Vietnam National University, HCMC. 268 Ly Thuong Kiet Street, Ward 14, District 10, HCMC * Email: kyphungng@ Received: 15th August 2016; Accepted for publication: 10th November 2016 ABSTRACT The paper presents a research on impact of climate change to salinity at water intake points of supply water factories and proposes adapting solution. In the research, the change precipitation induced flow as well as the change of discharge of reservoirs flow according to climate change scenarios are calculated by NAM and regulation of reservoirs models. These flows will be upstream boundary data for Mike 11 model to simulate salinity intrusion on the whole system, and sea level rise condition will be the downstream boundary data. After calculating salinity change at water intake points, solutions will be proposed based on simulation results as well as supply water planning under climate change condition. Keywords: salinization, Sai Gon – Dong Nai River, intake point, climated change. 1. INTRODUCTION In recent years, salinity of Sai Gon River (SGR) tends dramatically increasing. In addition, lack of water in upstream and salinization in drought season severely happen, as a consequence, those effect directly to supply water of HCMC. Although supply water companies themselves gave many solutions, they still stopped to take raw water because of over salinity and increasing production cost of .
