Letters exchanged in November 1946 between Lorenzo A. Richards and Henry J. Welge
No full textLetters exchanged in November 1946 between Lorenzo A. Richards and Henry J. Welge: (1) Letter dated 1 November 1946 from Henry J. Welge at Carter Oil Company, Tulsa, Oklahoma, to Lorenzo A. Richards at the U.S. Salinity Laboratory at Riverside, California, seeking a reference on soil moisture for a paper; (2) Letter dated 5 November 1946 from Lorenzo A. Richards to Henry J. Welge in response to his letter of 1 Novmeber 1946VICE PRESIDENT CD THE CARTER OIL COMPANY EXPLORATION DEPARTMENT NATIONAL BANK OF TULSA BUILDING TULSA 2, OKLAHOMA H. F. M O S E S POST OFFICE BOX 801 < November 1, 19^6 Dr. L. A. Eichards kk55 Fifth Street Riverside, California Dear Dr. Richards: I have been looking for a reference in connection •with a paper we are writing covering our displacement work, and thought you might be able to supply it to us even though you did not happen to be its author. The reference desired deals with displacement phenomena of water from soils at very high pressures, I think up to several hundred atmospheres. The point made in the reference was, that the water saturation of the soils can approach zero at sufficiently high capillary pressure. I hope you can help us in this matter. Yours very truly, Henry J. Welge HJW:h 3 t 0 o * V ! A A c A A f Q 0 § /6<0&9 L A-F. $. Regional Salinity Laboratory P. 0. Box 6?2 Riverside, California November 5, 19*+6 Mr. Henry J. Welge Carter Oil Company Tulsa 2, Oklahoma Dear Mr. Welge: Tour letter of November 1st was duly received, but I am not sure that I can be of much help to you. I have seen no published w*rk on moisture extraction from porous media at pressures greater then 20 atmospheres which was used in thp paper by myself and Weaver, "Moisture retention by some irrigated soils ae related to soil. moisture tensioc. Jour. Agr. Fes. 69:?15-?35, illus,W. •A paper by Bussell wSoil moisture sorption curves for four Iowa soils. Soil Sci. Soc. Amer. Proc. U?51-5h (1939) however, throws light on this subject. It is to be expected that the energy of absorption of water on soil minerals at oven-dry (105° C.) condition would be a constant for various soils. Huasell used centrifugation for moisture extraction, but this amounts to the same thing sn pressure membrane extraction. He extended his curves into the low moisture content range by vapor equilibrium over known sulfuric acid solutions. ^e scale he uses in plotting his data was devised by sn agricultural scientist for purposes of confusion. In this case, pF is simply the log rythm to the base ten of the equivalent soil moisture tension expressed in centimeters af water. It is seen from Russell\u27s data that moisture content of the soil approaches oven-dry at an extraction pressure equivalent to 10,000 stmospheres. He has done some work at the Laboratory up to 150 atmospheres with cellophane membrane, but this was the limit of our interest. I hope the above will be of use to you. Very truly yours.

Pricing Weather Derivatives
No full textThis article presents a general method for pricing weather derivatives. Specification tests find that a temperature series for Fresno, CA follows a mean-reverting Brownian motion process with discrete jumps and autoregressive conditional heteroscedastic errors. Based on this process, we define an equilibrium pricing model for cooling degree day weather options. Comparing option prices estimated with three methods: a traditional burn-rate approach, a Black-Scholes-Merton approximation, and an equilibrium Monte Carlo simulation reveals significant differences. Equilibrium prices are preferred on theoretical grounds, so are used to demonstrate the usefulness of weather derivatives as risk management tools for California specialty crop growers.

A mass-conservative control volume-finite element method for solving Richards’ equation in heterogeneous porous media
No full textWe present a mass-conservative vertex-centred finite volume method for efficiently solving the mixed form of Richards’ equation in heterogeneous porous media. The spatial discretisation is particularly well-suited to heterogeneous media because it produces consistent flux approximations at quadrature points where material properties are continuous. Combined with the method of lines, the spatial discretisation gives a set of differential algebraic equations amenable to solution using higher-order implicit solvers. We investigate the solution of the mixed form using a Jacobian-free inexact Newton solver, which requires the solution of an extra variable for each node in the mesh compared to the pressure-head form. By exploiting the structure of the Jacobian for the mixed form, the size of the preconditioner is reduced to that for the pressure-head form, and there is minimal computational overhead for solving the mixed form.\ud
\ud
The proposed formulation is tested on two challenging test problems. The solutions from the new formulation offer conservation of mass at least one order of magnitude more accurate than a pressure head formulation, and the higher-order temporal integration significantly improves both the mass balance and computational efficiency of the solution.\u

Richards to Charles Black in response to his letter of 3 January; (2) Letter dated 3 January 1969 from editor C. A. Black to Lorenzo A. Richards as the author of an article in a soils science book, soliciting corrections prior to a second printingI O W A S T A T E UNIVERSITY of Science chnology AMES, IOWA 50010 Department of Agronomy January 10, 1968 To: Authors, Monograph on Methods of Soil Analysis From: C. A. Black £7!77$. Subject: Correction of errors before second printing Copies of the first printing are about gone. Before preparing the second printing, we wish to eliminate all discovered errors. We need your help in this matter because the author is more likely than anyone else to know of errors. To make it easy for you to get the information to us, an unbound copy of your contribution to the monograph is enclosed. Please indicate the errors in the margin, as for proof corrections. Make note of both typographical errors and errors of text content. If you find it necessary to replace certain passages with new material, make the length of the new material as nearly identical with the old as you can. The type is not being reset for the monograph as a whole. Please mail the copy of your contribution with corrections by March 31 to the writer. This timing will give me opportunity to review all modifications and carry out any needed correspondence with the authors before the revised copy is forwarded to Mr. Dinauer. Thank you for your cooperation. I suspect many of you have shared my observation that copies of Monograph No. 9 characteristically have a well-worn character that testifies to constant use. It is gratifying to know that our colleagues so appreciate our efforts on this project that they not only buy the books but use them as part of their daily work
