Available in PDF, EPUB and Kindle. Book excerpt: Several example applications of water quality models were discussed to provide background into the development of a comprehensive mathematical model capable of evaluating water quality conditions in any river-reservoir system. A need exists for a river-reservoir water quality model which can be continuously updated and maintained with the best available concepts. The 'Water Quality for River-Reservoir Systems' (WQRRS) model was developed by the Hydrologic Engineering Center (HEC) to meet these needs. The HEC continuously updates the WQRRS based on the advantages of water quality research work brought to their attention. (Author).

Available in PDF, EPUB and Kindle. Book excerpt: This paper overviews the general features of computer program 'HEC-5, Simulation of Flood Control and Conservation Systems', with emphasis on the capabilities of the most recent release of HEC-5, Version 7.2, dated March 1991. HEC-5 can simulate the essential features and operation goals and constraints of simple or complex systems with simulation intervals ranging from minutes to one month. Single event flood analysis and period of record conservation analysis may be accomplished with the model. Flood control analysis includes balanced system operation for downstream damage centers with consideration of forecasted local flows and hydrologic routing. In addition, induced surcharge operation based on spillway gate regulation schedules can be simulated. Hydropower analysis may include run-of-river, peaking, and pumped storage plants as well as system power operation. Water supply simulation can include reservoir and downstream flow requirements in addition to divers ions and return flows. Water Quality analysis can include simulation of temperature, dissolved oxygen, up to three conservative and up to three nonconservative constituents.

Download or read book Water Quality Modeling That Works written by Wu-Seng Lung and published by Springer. This book was released on 2023-01-19 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book offers a practical guidance for environmental engineers and scientists charged with assessing the cause-and-effect of pollutants in receiving water systems. Instead of blindly running models, which is a practice seen too often in today’s field that can result in results with uncertainty, modelers must first understand the physical insights of the specific water systems in order to properly calibrate the parameters of the models. This book reinforces the critical importance of properly understanding the physical attributes of water systems by drawing on the author’s extensive experience in modeling with strong data support. This is also what sets this book apart from the volumes currently available in the water quality modeling field – nearly all other books in the field are categorized as textbooks, and unlike this book, offer few practical examples or exercises to follow. Environmental engineers and scientists engaged in quantifying the water quality impacts of pollutants to specific water systems will find this book valuable in their day-to-day practices. This book is a necessary volume for water quality engineers and scientists to consult for the regulatory planning and management of water systems

Download or read book HEC 5Q System Water Quality Modeling written by and published by . This book was released on 1986 with total page 23 pages. Available in PDF, EPUB and Kindle. Book excerpt: Several state-of-the art models are available for analyzing water quality conditions in complex reservoir systems for a given set of operational conditions. Some of these models can even make operational decisions regarding proper gate regulations to obtain a desirable water quality condition at a dam site for a given set of flow conditions. HEC-5Q, Simulation of Flood Control and Conservation Systems (Including Water Quality Analysis) computer model, has the unique capabilities to accept user-specified water quantity and quality needs system-wide and to decide how to regulate the network of reservoirs. The decision criteria are programmed to consider flood control, hydropower, instream flow (municipal, industrial, irrigation, water supply, fish habitat) and water quality requirements. The HEC-5Q program was first applied to the Sacramento River System in California and a report was published in July 1985. Two other applications are in progress the Kanawha and Monongahela River systems, and are expected to be completed by September 1986. Keywords: Reservoir System Analysis, Water Quality, Case Study, Stream System Analysis, Computer Model.

This paper presents review of model development and an overview of the capabilities and types of applications for the most recent computer programs, 'Simulation of Flood Control and Conservation Systems' (HEC-5) and 'Water Quality for River-Reservoir Systems' (WQRRS). Also, current research and development dealing with reservoir analysis are described. (Author).

Download or read book River Reservoir System Water Availability Modeling Support for Drought Management written by Ankit Bista and published by . This book was released on 2015 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Water Availability Modeling (WAM) System maintained by the Texas Commission on Environmental Quality (TCEQ) consists of the Water Rights Analysis Package (WRAP) and datasets for all the river basins of Texas. The modeling system is used to support long-term regional and statewide planning and evaluation of water right permit applications. The research is designed to explore and improve WRAP/WAM capabilities as a decision-support tool for drought management. The WRAP/WAM model for the Colorado River Basin is applied in this research in both long-term planning and short-term conditional reliability modeling (CRM) modes. A strategy using iterative long-term simulations is developed for modeling water management plans that combine interruptible and firm water supply commitments. The methodology is tested and demonstrated by application to the LCRA System. Improvements in water supply reliabilities provided by off-channel storage are also investigated in the simulation study. The research is designed to explore and improve modeling capabilities in general, not to support specific decisions regarding water management in this particular river basin. CRM features in WRAP provide short-term storage frequency and supply reliability analyses conditioned on preceding reservoir storage and can be employed as a decision-support tool for water management during drought or operational planning studies for preparing for future drought. The research explores alternative methods and combinations of options for performing various CRM tasks and develops several additional new options. Climate teleconnection patterns, drought indices, and flow persistence are investigated from the perspective of potential improvements to WRAP/WAM CRM capabilities. The literature regarding climate cycles and metrics for identifying these cycles is reviewed. Correlation analyses are performed to analyze the relationship between flows at selected sites on the Colorado River and various climate cycle indices. The correlations are generally found to be fairly weak. The Rapid Intervention Program (RIP) is designed for improving on-farm irrigation management strategies. A new interactive web interface tool being developed by other researchers at Texas A&M University, called the Irrigation Water-Use Efficiency Maximizer (IWEM), will link WRAP with RIP. WRAP CRM methods are tested and compared to determine the optimal combination of options for use with the IWEM platform.
