Publikováno v: Journal of Hydrology. 591:125676
An estimation method for evaluating groundwater velocity by means of the Single-Well Push-Pull (SWPP) test by Leap and Kaplan (1988) was applied to a confined aquifer at 100 m depth with a very slow groundwater movement. The SWPP test consists of a p

Distribution of quantities of submarine groundwater discharge on the Japanese Islands
Autor: Atsunao Marui, Narimitsu Ito
Publikováno v: Journal of Japanese Association of Hydrological Sciences. 40:1-18
Submarine groundwater discharge (SGD) is considered to be the sustainable water resource, and also the important factor of the water cycle. Methods to evaluate the quantity of SGD can be divided into mathematical analysis and in-site survey, and in t
