Unsteady Flow Toward Partially Penetrating Artesian Wells, Y. H. Huang Jun 1971

Unsteady Flow Toward Partially Penetrating Artesian Wells, Y. H. Huang

KWRRI Research Reports

A numerical method programmed for a high-speed computer was developed for determining the drawdown around an artesian well. A salient feature of the program is that it can be used for both fully and partially penetrating wells in either infinite or finite aquifers. The method Involves the application of finite difference equations to the well-known heat equation using a graded network. A comparison of the finite difference solutions with those obtained from the close-form formulas of Muskat, Theis, and Hantush indicates the validity of the method. A comparison between the finite difference solutions and the drawdowns measured on a sand …

Irrigating With Underground Water, T C. Calder

Journal of the Department of Agriculture, Western Australia, Series 4

MANY farmers in South-West areas are looking to irrigation to increase and diversify farm production, particularly on the sandy coastal plain where irrigation in summer is essential for vegetable, fruit and fodder production.
