Identifying effective forecast horizon for real-time reservoir operation under a limited inflow forecast
Identifying effective real-time a limited inflow forecast
2013/7/25
The use of a streamflow forecast for real-time reservoir operation is constrained byforecast uncertainty (FU) and limited forecast horizon (FH). The effects of the two factorsare complicating si...
