Description

Experimental Diocese of Hydrologic for Rainfall runoff

The present invention relates to an experimental teaching aid for simulating a rain runoff.

Rainfall-runoff is a process in which water that has fallen to the ground passes through component processes such as evaporation, transpiration, infiltration and percolation, and finally flows into the surface of a river. In order to solve water use, floods and droughts, it is essential to understand runoff, and the measured runoff is being used in the form of a hydrological curve. In particular, the hydrologic curve is of high importance in analyzing the amount of runoff in a watershed unit. However, in the course of the class, there is no teaching aid that can visually confirm the process of the hydrological cycle.

The soil surface of the vegetation body 51 by the inclination adjustment unit 53 may be a slope.

The fluid 60 is formed in a cylindrical shape and is made of a nonwoven fabric through which rainfall can flow. The upper end of the fluid 60 is inserted into the soil of the vegetation body 51 and the lower end is inserted into the soil of the deep part 40 . Accordingly, the soil of the surface soil vegetation part 50 and the soil of the deep part 40 are connected to each other through the fluid 60 so that moisture in the soil can flow up and down. That is, the moisture in the surface soil vegetation part 50 moves into the soil inside the deep part 60 through the fluid 60 (solid arrows in FIGS. 2 and 5), and the moisture in the deep part 60 is the fluid 60. It can move into the soil of the surface soil vegetation part 50 (dotted arrows in FIGS. 2 and 5) through the.

Therefore, it is possible to simulate the vertical movement of water through the fluid 60 and seepage in which the amount of rainfall permeated from the surface moves to the surface and the deep part. In addition, although the number of fluids 60 is shown as four in the drawing [FIG. 1], the number of fluids can be adjusted by reflecting the characteristics of the soil, such as the permeability coefficient.

Then, the weight of the surface soil vegetation part 50 and the deep part 40 is measured for each time unit by the weight measurement part 30 to calculate the amount of evaporation and transpiration lost to the atmosphere.
