Download or read book Wellbore and Groundwater Temperature Distribution Eastern Snake River Plain, Idaho written by and published by . This book was released on 2016 with total page 12 pages. Available in PDF, EPUB and Kindle. Book excerpt: A map of groundwater temperatures from the Eastern Snake River Plain (ESRP) regional aquifer can be used to identify and interpret important features of the aquifer, including aquifer flow direction, aquifer thickness, and potential geothermal anomalies. The ESRP is an area of high heat flow, yet most of this thermal energy fails to reach the surface, due to the heat being swept downgradient by the aquifer to the major spring complexes near Thousand Springs, ID, a distance of 300 km. Nine deep boreholes that fully penetrate the regional aquifer display three common features: (1) high thermal gradients beneath the aquifer, corresponding to high conductive heat flow in low-permeability hydrothermally-altered rocks; (2) isothermal temperature profiles within the aquifer, characteristic of an actively flowing groundwater; and (3) moderate thermal gradients in the vadose zone with values that indicate that over half of the geothermal heat flow is removed by advective transport in the regional aquifer system. This study utilized temperature data from 250 ESRP aquifer wells to evaluate regional aquifer flow direction, aquifer thickness, and potential geothermal anomalies. Because the thermal gradients are typically low in the aquifer, any measurement of groundwater temperature is a reasonable estimate of temperature throughout the aquifer thickness, allowing the construction of a regional aquifer temperature map for the ESRP. Mapped temperatures are used to identify cold thermal plumes associated with recharge from tributary valleys and adjacent uplands, and warm zones associated with geothermal input to the aquifer. Warm zones in the aquifer can have various causes, including local circulation of groundwater through the deep conductively dominated region, slow groundwater movement in low-permeability regions, or localized heat flow from deeper thermal features.

Book Synopsis Multi-scale Thermal Mapping of Submarine Groundwater Discharge in Coastal Ecosystems of Volcanic Islands by : Ebony Leah Williams
Download or read book Multi-scale Thermal Mapping of Submarine Groundwater Discharge in Coastal Ecosystems of Volcanic Islands written by Ebony Leah Williams and published by . This book was released on 2023 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Submarine groundwater discharge (SGD), or the flow of groundwater from land to sea, transports different constituents to the coast, such as nutrients, chemicals, and dissolved metals. In volcanic regimes, groundwater might have especially high concentrations of these constituents when, it is hydrothermal in origin. The Verde Island Passage, which lies within the Coral Triangle in the western Pacific, has been designated a marine protected area, as it is home to over thousands of different species of fish and coral reefs. Interactions of this constituent-rich groundwater with coastal waters through fractured volcanic rock can either pose a threat to or promote coastal ecosystem productivity and health. Because of this setting, it is known that SGD is a prevalent source of constituents, but how much and specifically where it is occurring is unknown. Thermal Infrared (TIR) remote sensing has gained popularity as a method of detecting SGD as it helps to resolve spatial variability issues that are inevitably accompanied by this phenomenon. Here, we investigate the use of TIR satellite and airborne remote sensing, coupled with ground-based field measurements including thermistor rods and fiber-optic distributed temperature sensing to identify and quantify submarine groundwater discharge in a coastal area of the Verde Island Passage. This study utilizes USGS Landsat 8 TIR sensor to regionally denote SGD plumes via temperature measurements of ocean water, as well as local airborne TIR remote sensing which provides a finer spatial resolution than its satellite counterpart. This study also employs a 1 km-long fiber optic cable to continuously measure temperature along the coast for the very first time in this region, and thermistor rods buried in the seabed under 20-30 feet of water to measure vertical temperature flux. Results from these approaches reveal multiple SGD signals in both the intertidal and subtidal zones, and tens of meters offshore, with temperatures reaching up to 80°C and estimated fluxes reaching as high as 1.5 m/d. From these approaches, we conclude that airborne TIR remote sensing and vertical thermal profiling are the most feasible thermal sensing methods employed in the study area, as they capture regional to local and point scaled SGD, which yield plume location, morphology, and flux. This study serves as a foundation for mapped SGD locations which can be used in conjunction with flux estimations in future temperature and flow modeling of SGD in the region. This study also has implications on potential outflow points of natural hydrothermal constituents and/or polluted groundwater, which can be of benefit to ecosystem and resource management

Chapter 1 introduces the terms salinity and sodicity and describes various salinity classification systems commonly used around the world. Chapter 2 reviews global distribution of salinization and socioeconomic aspects related to salinity and crop production. Chapters 3 covers comprehensively salinity and sodicity adaptation and mitigation options including physical, chemical, hydrological and biological methods. Chapter 4 discusses the efforts that have been made to demonstrate the development of soil salinity zones under different irrigation systems. Chapter 5 discusses the quality of irrigation water, boron toxicity and relative tolerance to boron, the effects of chlorides on crops. Chapter 6 introduces the role of nuclear techniques in saline agriculture.

Book excerpt: The authors preceive a trend in the study and practice of groundwater hydrology. They see a science that is emerging from its geological roots and its early hydraulic applications into a full-fledged environmental science. They see a science that is becoming more interdisciplinary in nature and of greater importance in the affairs of man. This book is their response, and they have provided a text that is suited to the study of groundwater during this period of emergence.
