Method for calculating non-point source pollution distribution in plain rivers
Water Science and Engineering, 2011 The land area in a river network is divided into certain-scale square cells for the sake of precision, and, based on the physical mechanisms of rainfall-runoff processes and runoff pollution, the non-point source pollution from cells is estimated using ...

A new method for multi-point pollution source identification
Atmospheric and Oceanic Science Letters, 2021 Abstract Rapid and accurate identification of the characteristics (source location, number, and intensity) of pollution sources is essential for emergency assessment of contamination events. Compared with single-point source identification, the reconstruction of multiple sources is more challenging.

Comparison of terrain corrections based on the point source and line source DC methods
Frontiers in Earth Science, 2022 In the direct current (DC) exploration method, topographic relief distorts the apparent resistivity curve. To eliminate effects of terrain fluctuations, two undulating terrains comprising valleys and ridges were investigated in the present study.
