Interest in converting portions of the large volumes of flood control storage capacity in federal multiple-purpose reservoirs in Texas and elsewhere to water supply and other conservation purposes has been growing for some time. Evaluation of storage reallocations involving tradeoffs between flood control and conservation purposes in multiple-purpose, multiple-reservoir systems represents a new area for applying the Water Rights Analysis Package (WRAP) and Texas Water Availability Modeling (WAM) System. A system of 12 multiple-purpose reservoirs operated by the U.S. Army Corps of Engineers (USACE) and Brazos River Authority (BRA) was adopted as a case study in this research to develop and test expanded WRAP/WAM-based methods for analyzing modifications in reservoir storage allocations and related system operations. The research consisted of the following tasks: The Brazos River Basin WRAP input dataset from the Texas WAM System (Brazos WAM) has a 1940-1997 hydrologic period-of-analysis. The research included developing and applying methods to extend the period-of-analysis to 1900-2007 providing a better representation of river basin hydrology. The methodology developed could potentially be used to update the other river basin datasets in the statewide WAM System. The Brazos WAM has 3,830 control points, 670 reservoirs, and hundreds of water rights. The research included developing and applying methods to create a much easier-to-apply condensed dataset focused on the USACE/BRA reservoir system and associated water rights that have only 48 control points and 14 reservoirs. The WRAP/WAM System was developed based on a monthly computational time step. The research included applying developmental methodologies for converting a monthly model to a daily time step that includes disaggregation of monthly naturalized flows to daily flows, calibration of flow routing coefficients, and incorporation of forecasting in the simulation. The WRAP/WAM System is designed for assessing water supply reliabilities and stream flow and storage frequencies from the perspective of conservative purposes. The research added flood risk indices to the WRAP modeling system in order to address tradeoffs between flood control and conservation purposes. The WRAP/WAM-based simulation study performed with the modified WAM dataset developed in this research demonstrates the improvements in water supply capabilities and tradeoffs with flood control associated with various reservoir storage reallocation strategies and other modifications in reservoir system operations.

Reservoir operation and storage allocation are important duties for agencies and water management professionals in Texas and elsewhere responsible for supplying water for municipal, industrial, and agricultural uses, hydroelectric power generation, recreation, navigation, and maintenance of instream flow for fish and wildlife, and protecting human lives and properties from flooding. Flood control capabilities for alternative reservoir storage allocations are assessed in the thesis research using the Water Rights Analysis Package (WRAP) with a daily version of the WRAP input dataset for the Trinity River Basin from the Texas Water Availability Modeling (WAM) System expanded to incorporate flood control operations. Tradeoffs between flood control and water supply in multiple-purpose reservoirs are analyzed. A system of eight multiple-purpose reservoirs operated by the United States Army Corps of Engineers (USACE) in the Trinity River Basin serves as a case study for this research. WRAP/WAM capabilities for simulating reservoir system operations for flood control were tested and improved. Frequency analyses of maximum annual storage levels were performed for both actual observed storage and storage computed by the simulation model for alternative modeling premises and reservoir operating strategies. The frequency analyses focused on determining the probability of exceeding flood control storage capacities. The Hydrologic Engineering Center (HEC) Statistical Software Package (SSP) was used to apply the log-normal and log-Pearson type III probability distribution functions. Various issues in simulating multiple-purpose reservoir systems and performing storage frequency analyses were investigated. Reallocations of storage capacity in the eight reservoirs from water supply to flood control can be implemented by raising the designated top of conservation pool. Impacts on flood control are evaluated in this study in terms of probability of overtopping the flood control pool. Impacts on water supply are quantified based on changes in reliability metrics. Alternative nine simulations are performed in WRAP for the eight Trinity River Basin Reservoirs. Three of the nine simulations are reallocation of storage capacities from flood control pool to conservation pool. Storage capacities, flood frequency analyses, and water supply reliabilities are compared and assessed for both actual observed storage capacities and simulation results.

Introducing the next generation in optimization modeling. This book presents a dynamic new approach to optimization modeling in the design and management of surface water reservoirs. More accurate in its representation of critical flows than traditional synthetic hydrology approaches, ReVelle's model utilizes both deterministic and stochastic constraints to derive a unified water supply, allocation, and reallocation optimization model. Dr. ReVelle begins with an in-depth presentation of conventional approaches to optimizing various reservoir functions and services-including water supply, flood control, hydropower, irrigation, navigation, and recreation. He then describes a method to enhance performance by allocating services and functions. Finally, he develops a unified optimization model that can be applied both to existing reservoirs and in the design of a new generation of efficient surface water reservoirs. A valuable working resource for water resources analysts, engineers, and managers, Optimizing Reservoir Resources features: * A new model to achieve desired levels of water supply reliability. * A multiobjective framework for exploring reservoir services. * Storage rule curves derived with anti-zigzagging methods. * Improved cost allocation models. * Original techniques for linearizing the nonlinear hydropower equation and for the derivation of the storage-energy curve. * Techniques for allocation and reallocation of reservoir services through the derivation of an economic supply curve.

The Corps' Hydrologic Engineering Center (HEC) has developed a generalized simulation model capable of analyzing complex river-reservoir systems. The development of the model, 'HEC-5, Simulation of Flood Control and Conservation Systems' (Eichert, 1974, 1975) has been paced by the changing mission of the Corps as well as the evolution of computer systems. HEC-5 development and management, including code development, testing, documentation, training and field application experience, is discussed. (fr).
