Abstract: In the present application, a method for assessing water shortage risk, device, computer device and storage medium are provided, wherein the method for assessing water shortage risk comprises: acquiring a volume of blue water flowing into soil of a to-be-assessed-area within a target time period, and a volume of retention water flowing into and retained in the soil of the to-be-assessed-area within the target time period; and determining a water shortage risk indicator of the to-be-assessed-area indicating a degree of water shortage risk of the to-be-assessed-area, according to a ratio of the volume of blue water to the volume of retention water. A higher ratio of the volume of blue water to the volume of retention water indicates poor ability of the soil's water to meet the demand for use and greater degree of the water shortage risk of the soil.

Abstract: The technical solution of the present application is applicable to the technical field of geophysical exploration, and provides a surface wave prospecting method and an acquisition equipment. This method comprises: obtaining vibration data by a vibration collecting device; calculating a dispersion graph by applying a vector wavenumber transform method to the vibration data, extracting dispersion curves from the dispersion graph, wherein the dispersion curves include fundamental mode and higher modes of dispersion curves of surface wave; establishing an initial stratigraphic model according to the dispersion graph; and performing a dispersion curves inversion based on the initial stratigraphic model and an inversion algorithm. The present technical solution can extract dispersion information of higher modes of surface wave from vibration data for reducing the non-uniqueness of inversion; computation time of the inversion algorithm can be reduced by establishing the initial stratigraphic model, and the instability of the inversion algorithm can be reduced, too. In this way, vibration collecting devices can be arranged arbitrarily, the requirement for the site layout is reduced, and the adaptability of surface wave prospecting is improved.
