Advancing reservoir operations modelling in SWAT to reduce socio-ecological tradeoffs

Journal Article Environmental Modelling and Software · November 1, 2022 The Soil & Water Assessment Tool (SWAT) is a useful model for evaluating socio-ecological tradeoffs and analyzing coupled natural-human system dynamics in agricultural watersheds. However, reservoir operating options in SWAT are limited. This study advance ... Full text Cite

Neuro-Evolutionary Direct Policy Search for Multiobjective Optimal Control.

Journal Article IEEE transactions on neural networks and learning systems · October 2022 Direct policy search (DPS) is emerging as one of the most effective and widely applied reinforcement learning (RL) methods to design optimal control policies for multiobjective Markov decision processes (MOMDPs). Traditionally, DPS defines the control poli ... Full text Cite

Policy Representation Learning for Multiobjective Reservoir Policy Design With Different Objective Dynamics

Journal Article Water Resources Research · December 1, 2021 Most water reservoir operators make use of forecasts to inform their decisions and enhance water systems flexibility and resilience by anticipating hydrological extremes. Yet, despite numerous candidate hydro-meteorological variables and forecast horizons ... Full text Cite

When timing matters-misdesigned dam filling impacts hydropower sustainability.

Journal Article Nature communications · May 2021 Decades of sustainable dam planning efforts have focused on containing dam impacts in regime conditions, when the dam is fully filled and operational, overlooking potential disputes raised by the filling phase. Here, we argue that filling timing and operat ... Full text Cite

Data-driven control of water reservoirs using an emulator of the climate system

Conference IFAC-PapersOnLine · January 1, 2020 This study presents a novel approach to combine a data-driven control strategy with an emulator model of the climate system in order to make the optimal control of water systems more flexible and adaptive to the increasing frequency and intensity of extrem ...
