Book Synopsis Simulation of Streamflow, Evapotranspiration, and Groundwater Recharge in the Middle Nueces River Watershed, South Texas, 1961-2008 by : Benjamin J. Dietsch
Download or read book Simulation of Streamflow, Evapotranspiration, and Groundwater Recharge in the Middle Nueces River Watershed, South Texas, 1961-2008 written by Benjamin J. Dietsch and published by Geological Survey (USGS). This book was released on 2012-01-01 with total page 37 pages. Available in PDF, EPUB and Kindle. Book excerpt: The U.S. Geological Survey---in cooperation with the U.S. Army Corps of Engineers, Fort Worth District; City of Corpus Christi; Guadalupe-Blanco River Authority; San Antonio River Authority; and San Antonio Water System---configured, calibrated, and tested a watershed model for a study area consisting of about 7,726 square miles of the middle Nueces River watershed in south Texas. The purpose of the model is to contribute to the understanding of watershed processes and hydrologic conditions in the middle Nueces River watershed. The model simulates streamflow, evapotranspiration, and groundwater recharge by using a numerical representation of physical characteristics of the landscape and meteorological and streamflow data. Model simulations of streamflow, evapotranspiration, and groundwater recharge were performed for various periods of record depending upon available gaged data for input and comparison, starting as early as 1961. Because of the large size of the study area, the middle Nueces River watershed was divided into eight subwatersheds, and separate Hydrological Simulation Program---FORTRAN models were developed for each subwatershed. Simulation of the overall study area involved running simulations in downstream order. Output from the model was summarized by subwatershed, point locations, stream and reservoir reaches, and the Carrizo-Wilcox aquifer outcrop area. Four long-term U.S. Geological Survey streamflow-gaging stations were used for streamflow model calibration and testing with data from 1990 to 2008. Monthly evaporation estimates from 2001 to 2008 and water-level data from 1961 to 2008 at Lake Corpus Christi also were used for model calibration. Additionally, evapotranspiration data for 2006-8 from a U.S. Geological Survey meteorological station in Medina County were used for calibration. Streamflow calibrations were considered poor to very good. The 2000-8 calibration results were characterized as good to very good for total flow volumes and for the volume of the highest 10 percent of daily flows. Calibration results for streamflow volumes of the lowest 50 percent of daily flows were considered poor. The daily streamflow calibration at U.S. Geological Survey streamflow-gaging station 08210000 Nueces River near Three Rivers, Tex., had the lowest (best) root mean square error, and U.S. Geological Survey streamflow-gaging station 08194500 Nueces River near Tilden, Tex., had the highest root mean square error expressed as a percentage of the mean flow rate. The mean daily reservoir volume during 1961-2008 was 182,000 acre-feet. Simulated mean daily reservoir volume was within 9 percent of this computed volume. Selected results of the model include streamflow yields for the subwatersheds and water-balance information for the Carrizo-Wilcox aquifer outcrop area. For the entire model domain, the area-weighted mean streamflow yield from 1961 to 2008 was 1.12 inches/year. The mean annual rainfall on the outcrop area during the 1961-2008 simulation period was 21.7 inches. Of this rainfall, an annual mean of 20.1 inches (about 93 percent) was simulated as evapotranspiration, 1.2 inches (about 6 percent) was simulated as groundwater recharge, and 0.5 inches (about 2 percent) was simulated as surface runoff.

Book Synopsis Karst Management by : Philip E. van Beynen
Download or read book Karst Management written by Philip E. van Beynen and published by Springer Science & Business Media. This book was released on 2011-06-21 with total page 490 pages. Available in PDF, EPUB and Kindle. Book excerpt: Focusing specifically on the management of karst environments, this volume draws together the world’s leading karst experts to provide a vital source for the study and management of this unique physical setting. Although karst landscapes cover 12% of the Earth’s terrain and provide 25% of the world’s drinking water, the resource management of karst environments has only previously received indirect attention. Through a comprehensive approach, Karst Management focuses on engineering issues associated with surface karst such as quarries, dams, and agriculture, subsurface topics such as the management of groundwater, show caves, cave biota, and geo-archaeology projects. Chapters that focus on karst as an integrated system look at IUCN World Heritage sites, national parks, policy and regulation, measuring systematic disturbance, information management, and public environmental education. The text incorporates the most up-to-date research from leading karst scientists. This volume provides important perspectives for university students, educators, geoengineers, resource managers, and planners who are interested in or work with this unique physical landscape.
Book Synopsis Groundwater Recharge and Wells by : R. David G. Pyne

Available in PDF, EPUB and Kindle. Book excerpt: Understanding the issues that have been encountered at other sites, and the steps that have led to successful resolution of these issues, can provide great help to those considering, planning, or implementing new groundwater recharge projects. Recent technical advances and operational experience have demonstrated that well recharge is a feasible and cost effective method of artificially recharging natural aquifers. This practical guide reviews the technical constraints and issues that have been addressed and resolved through research and experience at many sites. The book presents aquifer storage recovery (ASR) technology and traces its evolution over the past 25 years in the United States. Procedures for groundwater recharge are presented, and selected case studies are examined. Drinking water quality standards and conversion factors are provided in the appendix for easy reference.

This book was released on 2009-09-13 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Achieving a sustainable, reliable drinking water supply has emerged in recent years as an increasingly important goal, not only in the United States but also worldwide. This is being driven by population growth, increasing water demands, declining groundwater levels, contamination of water sources, greater awareness of adverse environmental impacts, concern regarding the potential impacts of global warming, and many other factors. Among the many methods that are being applied to achieve this goal, managed aquifer recharge is proving to be viable and cost-effective. Recent advances in the science of aquifer recharge, including the geochemistry, microbiology, and hydraulics, provide a strong foundation for the successful implementation of aquifer recharge projects. However, to achieve success, it is necessary to understand the lessons learned, taking advantage of good ideas that worked and not repeating the ideas that did not work. The overall goal of this project was to identify technical variables that result in successful design, operation, and maintenance of sustainable underground storage (SUS) facilities. The key objectives of the project were to increase the available knowledge base of SUS facilities throughout the United States, survey a variety underground storage facilities, identify and evaluate sites where SUS performance failed to meet objectives, address the use of SUS to reduce the vulnerability of water facilities, and create an easy-to-use, practical guidance document and outreach program to distribute research findings. The final report discusses surface and well recharge methods and includes a concise summary of the most important lessons learned from the 22 operating and failed recharge sites that were visited. It also includes a proposed analytical approach that may be applied for water utilities to reduce their vulnerability to service interruption and thereby enhance their system reliability. The appendix includes case studies for the 18 operating and four failed SUS facilities that were visited as part of this project. These are presented on a CD, providing useful perspectives regarding how different water utility systems have approached the need for SUS.
