Application of goal programming techniques for optimal reservoir operations
The optimal reservoir operations problem consists of obtaining releases, storages of a reservoir and downstream reach routed flows such that benefits derived from operating the reservoir are maximized. These are obtained on the basis of forecasted inflows to the reservoir, and forecasted …

Data quality enhancement in oil reservoir operations : an application of IPMAP
… Product MAP (IPMAP) methodology is used in reservoir pressure and reservoir simulation data, to propose data quality recommendations for the company under study. In particular, a new 4-step methodology for examining data quality for reservoir pressure management systems is proposed: 1. Trace …

Implications of the Value of Hydrologic Information to Reservoir Operations -- Learning From the Past
… the data mining procedure with conventional reservoir optimization techniques to build an enhanced stochastic dynamic programming (SDP) model. The enhanced SDP model is applied to the Shelbyville Reservoir, IL, and then compared to two classic SDP formulations. From a data mining procedure, …

Impacts of Reservoir Operations with Extreme Hydrologic and Climatic Conditions on Fish Sustainability below Shasta Lake
Reservoir managers on the Sacramento River are required by law to provide artificial cold water habitat downstream for endangered winter-run Chinook salmon. At Shasta Lake, a temperature control device was installed on Shasta Dam that allows selective withdrawal of reservoir water at different …

Developing a data-driven model for dynamic reservoir operation using a combined hidden Markov-decision tree and classification tree algorithms
Reservoir operations are faced with greater challenges than before due to growing water demands and climate change, and thus understanding and improvement of reservoir operations are critical. This study extends the hidden-Markov-decision tree (HM-DT) model developed by Zhao and Cai (2020) and …

The analysis of reservoir operation rules in the southwestern United States using a hidden Markov-decision tree model
Realistic reservoir operation is an important component in basin hydrological models. However, the operation rules can be complex under various situations and are not well understood yet. The objective of the study is to find out patterns of actual reservoir operation rules in a specific region …

A Dynamic Decision Support System for Drought Resiliency and Climate Change
… time period 2051-2070. Results show that utility operations are drought resilient for both scenarios, but substantially more stressed under the future drought conditions; due to a shift in the timing of snowmelt and runoff.. Dynamic monitoring of snowpack and drought conditions could help to ease …
