RISEstablishing Opportunities and Limitations of Forecast Use in the Operational Management of Highly Constrained Multiobjective Water Systems
Publisher: ASCE
Abstract: The potential utility of forecast information to improve reservoir control is well established, but physical, operational, and institutional constraints inhibit the full realization of these benefits. To help integrate ...
Influence of Subseasonal-to-Annual Water Supply Forecasts on Many-Objective Water System Robustness under Long-Term Change
Publisher: ASCE
Abstract: The sensitivity of forecast-informed reservoir operating policies to forecast attributes (lead-time and skill) in many-objective water systems has been well-established. However, the viability of forecast-informed operations ...
Hierarchical Bayesian Model for Streamflow Estimation at Ungauged Sites via Spatial Scaling in the Great Lakes Basin
Publisher: American Society of Civil Engineers
Abstract: This study presents a regional, probabilistic framework for estimating streamflow via spatial scaling for the purposes of informing water balance estimates in the Great Lakes basin. The framework follows a twofold strategy, ...
Evaluation of Environmental Degradation Kinetics Using Hierarchical Bayesian Modeling
Publisher: American Society of Civil Engineers
Abstract: This paper introduces the use of hierarchical Bayesian modeling as a method to estimate how kinetic properties of environmental contaminants vary across experimental factors. The hierarchical modeling framework utilizes a ...
Selecting Stochastic Climate Realizations to Efficiently Explore a Wide Range of Climate Risk to Water Resource Systems
Publisher: American Society of Civil Engineers
Abstract: There are significant computational requirements for assessing climate change impacts on water resource system reliability and vulnerability, particularly when analyzing a wide range of plausible scenarios. These requirements ...

Abstract: There are significant computational requirements for assessing climate change impacts on water resource system reliability and vulnerability, particularly when analyzing a wide range of plausible scenarios. These requirements ...
Spatiotemporal Impacts of Climate and Demand on Water Supply in the Apalachicola-Chattahoochee-Flint Basin
Publisher: American Society of Civil Engineers
Abstract: The transboundary Apalachicola-Chattahoochee-Flint (ACF) Basin in the southeastern United States has a long history of competition for water resources and litigation surrounding these conflicts. This case study applies the ...
Reservoir Management Optimization for Basin-Wide Ecological Restoration in the Connecticut River
Publisher: American Society of Civil Engineers
Abstract: Evidence from ecological studies suggests that the alteration of river flows downstream of reservoirs can threaten native aquatic ecosystems and the services they offer. Innovative revisions to water management practices ...
Improved Regionalization of the CN Method for Extreme Events at Ungauged Sites across the US
Publisher: American Society of Civil Engineers
Abstract: The curve number (CN) equation is a semiempirical, event-based model commonly used to estimate rainfall runoff. This model was originally developed in the 1950s to estimate storm runoff from 24-h rainfall events from small ...
Characterizing Hydrologic Vulnerability under Nonstationary Climate and Antecedent Conditions Using a Process-Informed Stochastic Weather Generator
Publisher: ASCE
Abstract: The evaluation of water systems based on historical statistics is problematic when shifts in the hydrologic system occur due to a changing climate. An explicit link to thermodynamic and dynamic pathways in the climate ...
