IAHR, founded in 1935, is a worldwide independent member-based organisation of engineers and water specialists working in fields related to the hydro-environmental sciences and their practical application. Activities range from river and maritime hydraulics to water resources development and eco-hydraulics, through to ice engineering, hydroinformatics, and hydraulic machinery.

Piecewise-linear operating rule for single reservoir using nsga-ii
Author : Taesoon Kim , Jun-Haeng Heo , Deg-Hyo Bae , Younghun Jung
Piecewise-linear operating rule for Soyanggang reservoir in Korea Peninsula is
developed using multi-objective genetic algorithms (NSGA-II) and time series modelling.
Implicit stochastic approach is applied and 100-year synthetic inflow is generated by
autoregressive order one (AR-1) time series model. The simulation model is performed to
evaluate the performance of the developed operating rule using historical average initial
storage at the start of year and historical annual inflow. Regression analysis is not necessary
to get the operating rule since each end point of piecewise-linear operating rule is calculated
by optimization model directly, and multi-objectives which are to maximize sum of
hydroelectric power production and to minimize water shortage index is considered to get a
proper operating rule. Although the piecewise-linear operating rule is developed with only
annual synthetic inflows which are larger than the sum of designated water supply, it can be
used when annual inflow is not enough to supply water resources to downstream. Storage and
release pattern also show good results comparing with historical operation.
