Hanoi, January 27th 2015 Rodolfo Soncini Sessa DEI – Politecnico di Milano IMRR Project 2 – Framing the system/problem INTEGRATED AND SUSTAINABLE WATER MANAGEMENT OF RED-THAI BINH RIVER SYSTEM IN A CHANGING CLIMATE
The Design Problem (It)(It) scenario
The Policy control information feasible control set state policy (It)(It) control law
What is a policy? h u t w t h u w t1t1 t1t1 Time = t 1 flood supply Policy t2t2 Time = t 2 t2t2 t2t2 101 control law
Reservoirs policy = one cohordinated policy for the 4 reservoirs Policy: a function m t (I t ) that at each day t, given the information I t suggests the optimal release u t from the four strategic reservoirs.
The Design Objectives (It)(It) objective Evaluating the effects: indicators and criteria hierarchy To day 10:00 -11:00
The system model (It)(It) stateexogenous input Modeling the system 1-4 To day and tomorrow
Strategic reservoirs Hanoi
Scheme of RTBR system Hoa Binh proper inflow
Son La (Ta Bu) and Hoa Binh proper inflows a 2 t+1 = a HB t+1 - a 1 t Hoa Binh proper inflow Hoa Binh total inflow Son La inflow = Ta Bu Correlogram of Ta Bu and Hoa Binh recorded flows ( )
Head water recorded data Son La Hoa Binh prop. Yen Bay Thac Ba Ham Yen Tuyen Quang Historical horizon
Reconstruction of Thac Ba inflow
Scheme of RTBR system DELTA Hoa Binh proper inflow The Delta Model Tomorrow 9:00 -10:00
The boundary conditions of the Delta model Water demand
Minor river flows
The tide
Tyde patterns (Son Dong station) Diurnal Semi-diurnal
Center of mass of the Earth-Moon system
The tide
Tide pattern (at Hon Dau) Spring tyde Neap tyde
The intake points
Gravity channels
Nhue canal at the end of the wet season
Nhue canal when the irrigation demand peaks
A pump served by a suction tank
How important is the tyde?
Hystorical flows and tyde
Hystorical flows + no tyde
2.3 meters at Hanoi + tyde
2.3 meters at Hanoi + no tyde
Comparison 2.3 at Hanoi historical flow
Historical Flows + tyde Historical Flows + no tyde 2.3 m at Hanoi + tyde 2.3 m at Hanoi + no tyde 52 Mcm +45% 2 Mcm The tyde cannot be neglected
The scenario (It)(It) exogenous input scenario The scenario 29 th January
