GRADUATE PROGRAM The graduate program in Soil and Water Sciences is administered by the Department of Environmental Sciences, and offers both M.S. and Ph.D. degrees. The University requires General Test scores (verbal, quantitative, analytical) from the Graduate Record Examination. As well as fulfilling the University requirements for admission to the Graduate Division, students must satisfy certain program requirements. Admission to the program requires a baccalaureate degree with preparation in both physical and life sciences. Students entering the program are expected to have completed one year of general chemistry, as well as courses in general physics, organic chemistry, calculus through integrals, general biology, statistics, and physical geology or physical geography. A student who has not taken these courses will be directed by the Admissions and Review Committee and his or her major advisor to the appropriate curriculum to correct the deficiencies. The student, in consultation with his/her Advisory Committee and other faculty as appropriate, will develop a program of coursework to satisfy the degree requirements and the student's career objective. A study list of required and elective courses must be completed by the end of the second quarter of study and submitted to the Admissions and Review Committee for review. All students must complete one course in each of the following four broad categories of soil and water sciences: chemistry, physics, biology, and natural structure and diversity. Students may have completed these prior to admission or they may take them early in their graduate program. Courses at UCR that meet the requirement of each category are listed below. Chemistry SWSC 104: Soil Chemistry
Physics SWSC 107: Soil Physics
Biology SWSC 102: Soil Conditions and Plant Growth
Natural Structure and Diversity SWSC 118: Soil Morphology and Classification
In partial fulfillment of requirements for an advanced degree in soil and water sciences, all graduate students must present a departmental seminar summarizing results of his/her thesis or dissertation or internship. This requirement is formalized by enrolling in SWSC 250 for two units during the final quarter of matriculation. For a complete description of the program's requirements, students are referred to the Guidelines for Graduate Students available in the Environmental Sciences Student Affairs Office. Other General University requirements for advanced degrees are given in the Graduate Studies section of this catalog. MASTER'S DEGREE
Two options are available for students seeking the M.S. degree. Under Plan I, the thesis plan, a minimum of 36 quarter units of graduate and upper-division undergraduate courses in, or significantly related to, soil and water sciences are required. At least 24 of the 36 units must be in graduate courses. A maximum of 12 of these units may be in graduate research for the thesis. No more than 4 units of SWSC 290 and 2 units of SWSC 250 may be applied toward the degree. A final oral examination must be passed.
Under Plan II a minimum of 36 quarter units of graduate and upper-division undergraduate courses in, or significantly related to, soil and water sciences are required. At least 18 units must be in graduate courses. No more than 2 units of SWSC 250 and 6 units of SWSC 298-I may be counted toward the required 18 units, and no units from graduate research for thesis or dissertation (SWSC 297 or SWSC 299) will be applicable.
Only seminar courses, directed study, internship, thesis and dissertation hours may be taken on a Satisfactory (S) or No Credit (NC) basis.
A comprehensive written examination that covers fundamental topics in soil and water sciences is required of all Plan II students. The written exam, which is three to four hours in length, is prepared and evaluated by a committee appointed by the Department Chair. The exam is taken during the latter part of the final quarter in the M.S. program. Students must wait at least eight weeks before retaking a failed examination. Students failing the examination twice are dismissed from the program.
DOCTORAL DEGREE
The Ph.D. program provides specialized, research-based training in a variety of soil and water sciences fields. In addition to the four core courses enumerated above, the minimum requirements for the Ph.D. degree include the following:
Before advancement to candidacy, students must complete all required course work as approved by their Advisory Committee, pass a written qualifying examination administered by a five-member committee, and pass an oral examination administered by the same committee; the latter includes the defense of an original research proposal. The examining committee must include one member from outside the graduate program. After successfully completing these examinations and complying with university rules, students are advanced to candidacy.
A dissertation consisting of original research in the field of soil and water sciences is required. The dissertation must be accepted by a three-member Dissertation Committee. The student must then pass a final oral examination, which deals primarily with the dissertation and is conducted by the Dissertation Committee.
The normative time to the Ph.D. degree is 15 quarters.
