Abstract:

        The Hutuohe River has been a flood discharge alleyway after the build of the Huangbizhuang and Gangnan reservoirs in the exit of Taihangshan. Because the surface water is holded up,the shallow groundwater is bankrupt in discharge function of the surface water.Under the condition of intermit flood, the shallow groundwaters in different distances from riverway appear marked spatiotemporal dynamic changing rules and different responds. Based on the analysis of long-term observation data, this article sums up the dynamic changing rules as following, in the view of time, the groundwater levels in different distances from the river have different rising and falling rules,from the viewpoint of space, the groundwater level changes slow down gradually with the distance from the center of the river growing.

Key words: Hutuohe alongshore, shallow groundwater, changing rule
