   ·Description of the course (what, why, philosophy, teaching methodology)

       It is a Surface Water Hydrology Analysis of the basic principles of surface hydrology. The precipitation, evapotranspiration, infiltration, and run off components of the hydrologic cycle are discussed in detail. Topics include water balance, precipitation analysis, unit hydrograph theory and Flood prediction.

Course Objectives

    • Students will obtain an understanding of hydrologic processes, particularly the

processes of precipitation, evaporation, infiltration, and surface water.

    • Students will learn about methods of hydrologic analysis, including unit hydrograph,

flow routing, statistical methods and frequency analysis in hydrology.

    • Students will learn about methods of hydrologic design, including the development of

design storms and design flows.

    • Students can estimate the time of concentration of a watershed, based on

information about surface type and travel length, slope, and rainfall intensity.

        • Students can estimate peak discharges and develop unit hydrographs and design

hydrographs for small-scale watersheds.

    • Students have a basic understanding of hydrologic and hydraulic methods of flow

routing.

    • Students can apply current software to the hydrologic design of small-scale rural or

urban watersheds.

Prerequisites by Topics:

    • Calculus

    • Statistics

    • Fluid Mechanics

    • Open channel Flow

..

  Computer Usage: Students have the option to complete homework using compute        applications such as spreadsheets and word processors

  Approach: The homework and tests are designed to train the students to think about a variety of hydrology-related problems, show the interconnection between the various components of the hydrologic cycle.,  . In the context of this design process, students develop skills that constitute design components:

                    analysis and synthesis skills, creative and original thinking,

                    problem-solving when the problem itself and problem constraints

                    are not clearly defined.

Grading Policy

 Your grade depends on in-class participation and performance on your quizzes, exams, and assignments.

 Quizzes: Bi-weekly quizzes will be brief (about 5 mins.) and are intended to help prepare you for the exams.

 Exams: Exams will be a combination of multiple choice and short-answer questions, and will also have components similar to the work you do on the problem sets. Make-up exams can be arranged if extraordinary circumstances prevent you from taking the exam at the scheduled time. Be sure to arrange for a make-up as soon as extenuating circumstances arise.

 Assessment of final course grade will be based on:

Quizzes                   10%

Homework              20%

Exam 1                    15%

Exam 2                    15%

Final  Exam             40% 

  TOTAL                     100%

REVIEW OF BASIC MATHEMATICS

 The following short review of basic mathematics may be useful to you in solving the problems.

    LOGARITHMS

     The logarithm of a number is the exponent of that power to which a base number must be raised to yield the value of the number. There are two bases. Common logarithms use the base 10 and are designated by log. Natural logarithms use the base 2.718… and are designated by ln. The number 2.718… is also designated by the letter e.

  The log of 25.7 is 1.409933 and may be found by entering the number 25.7 on your calculator and then pressing the “log" key. This means that if you take the number 10 and raise it to the 1.409933 power, you will get 25.7. You can do this on your calculator by entering 10, pressing the “y^x" key, entering 1.409933 and then pressing the “=” key. This process is known as finding the antilog or inverse log of a number. Thus, if 1.409933 is the log of 25.7, then 25.7 is the inverse log of 1.409933.

 The ln of 25.7 is 3.246491 and may be found by entering the number 25.7 on your calculator and then pressing the "ln x" [or “ln"] key. This means that if you start with e and raise it to the 3.24691 power, you will get 25.7. If you have an “ex" key on your calculator, you can enter 3.246491 and the press the “ex" key to yield 25.7. If you don't have an “ex" key, you can still perform the operation. Since we are finding the inverse ln, enter 3.246491 and press the “INV" key followed by the “ln" [or "ln x"] key.

Logarithms have the following relationships:

                 log ab = log a + log b

                 log a/b = log a -log b

                 log an = n log a

 Both the natural and common logarithm of 1.0000 is 0. The logarithm of any number greater than 1.0000 is positive. The logarithm of any number less than 1.0000 is negative.

             The log of 10 is 1, the log of 100 is 2, the log of 1000 is 3, etc.

    EQUATIONS FOR AREA

                Area of a circle with radius r

     A =  pr²           (pi = 3.1416)

              Area of a triangle with a base b and altitude h    

    A = 1/2 bh

Area of a rectangle with sides a and b

    A = ab

             Area of a parallelogram with sides a and b and an included angle z

    A = ab sin z.

             Area of a trapezoid whose parallel sides are a and b and with an altitude h

    A = 1/2(a + b)h.

    EQUATIONS FOR CIRCUMFERENCE

             Circumference of a circle with a diameter  d

        C = p d.

Circumference of a triangle of sides  a, b and  c

        C = a + b + c.

Circumference of a rectangle with sides a  and  b

                    C  = 2 a +  2b.

    EQUATIONS FOR VOLUME

             Volume of a regular prism

    V = area of base x altitude.

             Volume of a pyramid

    V= 1/3 area of base x altitude.

             Volume of a cylinder with radius r and height h

    V = p r² h

Volume of a cone with radius r and height h

    V = 1/3 p r² h

    EQUATION OF A STRAIGHT LINE IN RECTILINEAR 

    COORDINATES

                             y  =   m x + b

        where :

        m     is the slope of the line 

        b     is the intercept of the y axis.

    TRIGONOMETRIC FUNCTIONS OF A RIGHT TRIANGLE

             Sine A = sin A = a/h

            Cosine A = cos A = b/h

            Tangent A = tan A = a/b

            Cotangent A = cot A = b/a

            Secant A = sec A = h/b

            Cosecant A = csc A = h/a

    DIFFERENTIALS

             d ax = a dx

             d (u + v) = du + dv

             d uv = udv + vdu

             d (u/v) = (vdu – udv)/v²

             d xⁿ = n x^n-l dx

    d x^y = yx^y-1 dx + x^y ln x dy

             d e^x = e^x dx

             d e^ax = a e^axdx

             d a^x = a^x ln a dx

             d ln x = x ^-1 dx

             d log x = x ^-1 log e dx
