Water is intrinsic to all living systems, to civilization, event to the earth itself. In the atmosphere, it manifests as weather and climate; on the earth’s surface it shapes landscape, nourishes life, and supports human endeavor. Underground it permeates soil and rock, migrates through vast subterranean aquifers and reemerges in springs, wetlands and surface waterways. In the sequence known as the hydrological cycle it passes into the atmosphere as water vapor, precipitates to earth, and returns to the atmosphere through evaporation. Often too, it wreaks devastation in floods, drought, landslides, avalanches, debris flow, land subsidence, and sudden fault movement. And, increasingly, under the intense pressures of a growing world population and the demands of agricultural and industrial activities throughout the globe, water is degraded by pollutants and depleted by overuse.
Water is Intrinsic to Life
Hydrologic Science is the study of water in all of its aspects as weather, as river basins, as groundwater, as glaciers, as lakes, as streams, as permafrost, as water vapor. Hydrologists measure and analyze water beneath the ground, on the earth’s surface, and in the atmosphere to determine how water is affected by physical, chemical, and biological processes on earth.
Because hydrologic processes touch many disciplines, hydrology has traditionally been studied as a subspeciality of engineering, geology, or agricultural science. But growing awareness of water’s fundamental role in the environment and of the scope and critical nature of water problems worldwide has brought about recognition of the need for a broader, more congruent approach to hydrologic study.
In 1991 the National Research Council, pointing to an undersupply of qualified hydrologists in both the short-term and the foreseeable long-term, called for hydrologic science to be formulated as an independent scientific discipline with distinct training and research programs to bring about "a coherent understanding of water’s role in the planetary-scale behavior of the earth’s system". Just as vital is the need to understand the dynamics of water on other, smaller scales—at the continental, water-shed, and microscopic levels
A Comprehensive Program
UC Davis has responded to the need for a comprehensive hydrologic science curriculum with a new multidisciplinary program—a vigorous integration of chemistry, physics, biology, geology, soil science, engineering, mathematics, and atmospheric science. The hydrologic science program at UC Davis encompasses both undergraduate and graduate study—at present one of only two such programs in the country. The undergraduate hydrologic science program offers both a major and a minor in hydrologic science, leading to a BS degree. The graduate level offers three degree options—hydrology, hydrobiology, and hydrogeochemistry—at the MS and PhD levels. Within each graduate-level option, students can specialize in defined areas of study or develop an individualized program under the guidance of a faculty advisor.
The Hydrological Science Major is diverse and interdisciplinary. Designed to introduce students to a broad range of hydrologic processes, the coursework forms the basis for specialization in such areas as surface or groundwater hydrology (hydrogeology), hydrochemistry, hydrobiology, water management, and irrigation. Courses cover hydrologic processes from the perspectives of various disciplines—atmospheric, soil, plant and water sciences, engineering, and geology. Students in the major program complete a total of 180 units, including 72 units of rigorous coursework in the natural sciences and mathematics, along with general education coursework, followed by 44-54 units of in-depth coursework in physical and chemical hydrology along with water policy/social awareness, and 16-26 units in a chosen area of concentration, such as water quality, irrigation and drainage, groundwater hydrology, and surface hydrology. A concentration in groundwater hydrology requires a number of foundational courses in geology.
The Minor Program is designed for natural sciences students who have an interest in water and environmental issues. The coursework provides fundamental understanding of hydrologic science, enabling the student to pursue broad career opportunities in this growing field. The minor allows for enough flexibility to enable students to pursue water issues and problems of particular interest. Students earning the minor take a minimum of 20-22 units in hydrologic science, including a required principles of hydrologic science course and an array of other classes chosen from a list of offerings, including groundwater hydrology, the biology of running waters, water law, environmental law, irrigation principles and practices, soils in land use and the environment, water quality, salt control and reclamation, groundwater hydrology, soil microbiology, biometeorology, plant-water-soil relationships, and aqueous geochemistry.
Internship and Career Opportunities
As a discipline, hydrologic science is steadily expanding over time and space, extending from delicate interactions between plant leaves and moisture to global-scale atmospheric events, and from short-lived phenomena to seasonal cycles, to climatic change evolving over centuries. With this expansion and with the urgent need to address water problems worldwide has come an opening up of career possibilities in the field—opportunities that remain largely independent of economic cycles. Well-trained hydrologists are needed, for example:
- To find more efficient ways to use scarce groundwater and surface water resources;
- To examine the effect of acid rain on the environment;
- To find ways of preventing subsurface and surface waters from becoming polluted by urban runoff, leaky underground storage tanks, and agricultural drainage;
- To define water quality criteria for drinking water and for fish and other aquatic life;
- To forecast and plan for floods and droughts;
- To understand the social dimensions of water use and to help bring about balance among competing water needs;
- To analyze risk in the operation of surface reservoirs;
- To find ways to replenish groundwater;
- To trace water’s role in the formation of underground ore and petroleum deposits;
- To examine the exchange of water, sediment, and nutrients between river channels and floodplains
The need for experts in subsurface hydrology to address the growing problem of contaminants seeping into the earth and contaminating groundwater aquifers is particularly acute. Hydrologists are needed in private industry and in regulatory agencies to help identify and clean up the contamination, in research laboratories and universities to develop new technologies for addressing contamination problems, and in universities to help train new hydrologists.
California, where the demand for high quality water chronically exceeds supply, affords ample and unique opportunities for the study of hydrology and for careers in hydrologic science. Nowhere is water more central to public policy decision-making than in California, with its burgeoning urban populations and multi-billion dollar agricultural industry concentrated in the mostly arid central and southern regions of the state, its vast water distribution system, and the intense competition for high quality water for domestic use, industry, fish and wildlife, agriculture, and recreation. Groundwater overdraft and contamination, soil salinity, farmland erosion, periodic flooding and drought, saltwater intrusion from oceans into freshwater, seepage from septic tanks, landfills, mine spoils, oil spills, the sharpening conflict between human beings and nature for the use of water, and the need to balance water use to prevent exhaustion of natural resources makes the state a living laboratory for the study of hydrologic problems and principles providing insights applicable all over the world.The Greater Sacramento-Davis Area offers numerous career and internship opportunities with consulting firms, private industry, environmental interest groups, and agricultural concern, as well as with government agencies and research laboratories, including the U.S. Geological Survey, U.S. Fish and Wildlife Agency, U.S. Forest Service, Soil Conservation Service, California Environmental Protection Agency, California Water Resources Control Board, Regional Water Quality Control Boards, the California Departments of Conservation and Fish and Game, and Lawrence Livermore National Laboratory.
