Hydrogeology hydro- meaning water, and -geology meaning the study of the Earth) is the area of geology that deals with the distribution and movement of groundwater in the soil and rocks of the Earth's crust , (commonly in aquifers ). The term geohydrology is often used interchangeably. Some make the minor distinction between a hydrologist or engineer applying themselves to geology (geohydrology), and a geologist applying themselves to hydrology (hydrogeology). Contents Introduction Hydrogeology in relation to other fields Definitions and material properties Hydraulic head ... edit Introduction Hydrogeology (like most earth sciences ) is an interdisciplinary subject; it can be difficult to account fully for the chemical physical biological and even legal interactions between soil water nature and society . The study of the interaction between groundwater movement and geology can be quite complex.

Hydrology is the science of water occurrence, movement and transport. Hydrogeology is the part of hydrology that deals with the occurrence, movement and quality of water beneath the Earth's surface. Because hydrogeology deals with water in a complex subsurface environment, it is a complex science. On the other hand, much of its basic terminology and principles can be understood readily by non-hydrogeologists. This section presents basic terms and principles of hydrogeology. The first section introduces many key terms and concepts in definition form. Subsequent definitions include graphics to aid in explanation. The following sections introduce principles of a ground water movement, using these terms. Graphics are included to further define terms and illustrate concepts.

Current Projects Publications Staff The Hydrogeology Department (HD) consists of more than 50 scientists, postdocs, research associates, and graduate students carrying out a broad range of cutting-edge research in fundamental and applied hydrology. HD has expertise in theoretical, experimental, field, and modeling approaches in a variety of research areas, among which are unsaturated zone hydrology (including fracture flow and transport), reservoir engineering (including pore-level modeling and gas hydrate studies), contaminant hydrology (including reactive and colloid-assisted transport), and coupled nonisothermal, geochemical, and geomechanical processes. The HD addresses national needs in the areas of subsurface energy resource recovery, subsurface remediation, geologic CO2 storage, and nuclear waste disposal. Highlights of research efforts in these areas over the last two years include the following: Subsurface Energy Resource Recovery Subsurface Remediation Geologic CO2 Storage Nuclear Waste Disposal in the Unsaturated Zone A considerable amount of general unsaturated zone hydrology knowledge and understanding is generated by HD researchers. For example, new broadly applicable conceptualizations of fracture-matrix interaction and scale dependence of matrix diffusion have been investigated. Often models developed in one area find application in other areas. The large effort in HD on a broad range of hydrologic processes related to nuclear waste disposal typifies the strong integration of field, laboratory, and modeling analyses characteristic of ESD scientific investigations.

What is hydrogeology? Hydrogeology is the study of groundwater and its qualities: flow, amount, speed, direction, sustainability, extraction or replenishment capabilities. Hydrology includes this and the study of the properties, quantity, and distribution of both surface and underground waters. Hydrogeology is an underground specialty within the broader field of water resources. What is a hydrogeologist? What do they do? A hydrogeologist evaluates the quality, quantity, reliability and sustainability of all aspects of water resources. With this information the hydrogeologist makes management recommendations. They study the properties of underground and surface waters, locate water and energy resources. They may predict water-related geologic hazards or give environmental site assessments or advice on hazardous-waste-site remediation. What do qualifications do hydrogeologists need?

About DWR Contact Us Jobs News ... Hydrogeology Basic Hydrogeology Aquifer - "A water-bearing layer of rock, or of unconsolidated sediments, that will yield water in a usable quantity to a well or spring." Confining Bed - "A layer of rock, or of unconsolidated sediments, that retards the movement of water in and out of an aquifer and possesses a very low hydraulic conductivity." From these definitions, all rocks can be thought of as either aquifers or confining beds. Moreover, aquifers are often considered to be unconfined or confined. An aquifer is considered unconfined if water only partially fills the aquifer materials and water freely rises and declines along the unsaturated/saturated zone boundary. These unconfined aquifers are often referred to as water-table aquifers and wells that are opened to these unconfined aquifers indicates the position of the water-table. A confined aquifer is generally defined when water completely fills the aquifer materials and is overlain by a confining bed. A common term for a confined aquifer is an artesian aquifer. The water level from a well that permits water solely from a confined aquifer to enter the well will stand at some point above the top of the confined aquifer but not necessarily above the land surface. The water level in a well open to a specific confined aquifer stands at the level of the potentiometric surface. If the potentiometric surface is above land, the well is often considered as a free-flowing artesian well. Reference: modified from Heath (1993)

Hydrogeology of the Edwards Aquifer Formation of the Edwards Aquifer Present Hydrogeology Movement and Storage of Water in the Aquifer Water Quality and Aquifer Protection The key to why the Edwards is a good aquifer lies in the fact that the limestone was exposed, extensively eroded, and then covered over again with new limestone formations. When the Edwards limestone was exposed, erosion created cavities and conduits and made the limestone unit capable of holding and transmitting water. When it was covered over again, the new sediments were relatively impermeable and formed a confining unit . The story of how the Aquifer formed begins a long time ago... About 500-600 million years ago in the Paleozoic era, long before the calcium precipitate that became the Edwards limestone was deposited on the seafloor, the area that is now the Gulf of Mexico was high and mountainous and an ancient sea came in from the northwest. A shoreline extended through Texas from southwest to northeast and sediments from erosion were fed to the northwest (see Figure 1). By the Jurassic period of the Mesozoic era, about 200 million years ago, a massive change had occurred that no one really completely understands.

Hydrogeology Idaho Geological Survey Primacy over managing and regulating the state's water rights and water quality lies with the Idaho Departments of Water Resources and Environmental Quality, respectively. The Idaho Geological Survey, a non-regulatory agency, works closely with these and other state agencies, providing unbiased technical assistance, conducting applied hydrogeologic research, and mapping the geologic and hydrogeologic characteristics that are critical to informed water-resource decisions. Ground Water. Idaho's ground water is one of the state's most valuable natural resources. If water were so classified, it would be Idaho's most valuable mineral resource. Ground water accounts for over 20% of Idaho's 20 billion gallons of daily water usage and for over 92% of the state's drinking water supply. Over six trillion gallons of water are applied annually to almost four million irrigated acres of land, supporting a $5.3 billion agricultural economy. Half of this acreage is irrigated by ground water which represents only one fifth of all agricultural water usage, a fact that reflects the greater efficiency of sprinkler-based irrigation over flood irrigation methods.

Ground water is the largest and most readily available source of potable water in Florida. Hydrogeology is the study of ground water with emphasis given to its chemistry, modes of movement, and relation to the geologic environment. Hydrogeology integrates geology, hydrology, chemistry, physics, mathematics, biology, and engineering to understand the occurrence and movement of water in the complex subsurface environment. Water-bearing sedimentary rocks in Florida can generally be divided into two types: siliciclastics (sands, silts, clays) or carbonates (limestone and dolostone). All of these rocks, no matter how "hard" or solid they appear, contain some voids or pores, which may contain water. Two properties that are common to all these rocks, and which control the movement of their ground water, are porosity and permeability. Porosity and permeability are intimately related. Porosity refers to the pores themselves, while permeability is a measure of a rock's ability to allow fluids to move through its pores. For a rock to be permeable, its pores must be interconnected so that water can move freely.

Karst Geomorphology and Hydrogeology, Principal References Based upon original printed compilations by Ernst H. Kastning, Associate Professor of Geology, Radford University. Additional revsions and HTML programming by Ira Sasowsky and Paula Dungjen, Dept. of Geology, University of Akron. INTRODUCTION This bibliography provides a handy list of some important, standard references on karst and cave geology. Most works are in English, and this is not an exhaustive bibliography on the subject; however, it serves as a key to works that in turn lead the researcher to additional material. The intent is to provide a selected list of primary sources to those who are relatively unfamiliar with karst research. This edition contains 124 citations and 6 journals. Listings such as this one are inherently biased due to the background of the persons who compile them. Undoubtably many worthy publications have not been placed on this list. For this, we apologize, and hope that the presented list will be of use to those who view it. The bibliography is arranged as follows: Textbooks on karst and speleology Monographs that introduce the principles of karstic landform development, the origin of caves, and the geomorphic, hydrologic, and geochemical processes of karst. Emphasis is placed on texts originally written in the English language or on foreign language books translated into English.
