This paper describes analyses being performed to aid in the development of operation strategies for the Long Term Flow Test at the Hijiori Hot Dry Rock reservoir, Japan. Testing has shown that the reservoir is dominated by flow in natural fractures that connect the reservoir to the far-field. When the injection flow is doubled, the production flow rate stays approximately constant. Also, during...

This paper utilizes the Colliding Bodies of Optimization (CBO), Enhanced Colliding Bodies of Optimization (ECBO) and Vibrating Particles System (VPS) algorithms to optimize the reservoir system operation. CBO is based on physics equations governing the one-dimensional collisions between bodies, with each agent solution being considered as an object or body with mass and ECBO utilizes memory to ...

Water reservoir programming studies aim to determine the final cultivated land area based on predefined agricultural models and water requirements. Dam utilization rule curve is also provided in such studies. The system of Dez dam water resources was simulated applying the basic information in order to determine the capability of its reservoir to provide the objectives of the performed plan. As...

A novel multi-objective simulation-optimization (S-O) framework for flood mitigation in a river-reservoir system with multiple reservoirs and control points is proposed. Different combinations of objectives regarding flood mitigation in one or more of the reservoirs and/or one or more of the control points can be specified within the framework, namely, (1) maximizing the flood releases from the...

We extend the non-Markovian quantum state diffusion (QSD) equation to open quantum systems which exhibit multi-channel coupling to a harmonic oscillator reservoir. Open quantum systems which have multi-channel reservoir coupling are those in which canonical transformation of reservoir modes cannot reduce the number of reservoir operators appearing in the interaction Hamiltonian to one. We show ...
