Interflow collection facility 2 course of work is: when on-test, and the interflow of observing each layer (that is, each water leg 2-1) in interflow collection facility 2 goes out the stream time, and record each layer respectively go out the stream time.From going out stream, the interflow of each layer is collected in the collection bottle 2-2 of equivalent layer position in 5 minutes by the general setting of timing, measures the water yield of equivalent layer position collection bottle 2-2.Observe going out fluid layer position and going out the stream time of tracer agent simultaneously.And render to according to tracer agent the time that collection facility occurs first, calculate interflow mean flow rate.According to the water yield that each layer timing measures, analyze the discharge process dynamic law of different layers position interflow.Also according to pollutant levels in collected water sample, calculation pollution intensity can be asked.
Embodiment one: in natural rainfall situation, the mensuration of interflow flow velocity and interflow flow dynamics calculate
The first step.According to testing requirements, as mentioned above, first, domatic construction have specific grade, water system independently slope runoff community, ensure that domatic soil layer does not disturb; Secondly, dig consistent with cell-wide, the degree of depth reaches a chorizon vertical section in the lower end of slope runoff community, interflow collection facility 2 is arranged in excavated section.Interflow gathering-device 2 adopts hierarchical design, presses 150mm design, is generally designed with 4-5 layer for every layer, can according to the excavated depth profiled adjustment number of plies; Then, tracer agent is settled to throw in facility 1 in the inner side on the border, upper end of slope runoff community.According to test design requirement, facility thrown in by tracer agent will be placed in domatic certain depth, is generally 50mm-100mm (see Fig. 1).
Second step.Slope runoff community and relevant tracer agent input facility 1 and interflow collection facility 2 at runoff plots outer ledge, gather pedotheque, the initial water content of testing soil after building and installing.Start in rainfall, record start time, measure rainfall intensity and rainfall amount at runoff plots outer ledge.
3rd step.Observation slope runoff community slope runoff and different depth interflow go out to flow the moment, then, collected the interflow of slope runoffs and each layering every 5 minutes, and add up the run-off collected different layers position, until this rainfall terminates.Go out now first in interflow, will the tracer agent release of upper end, slope runoff community be arranged on, and the record release moment.Then, on the layering gathering-device of the interflow collection facility 2 of lower end, slope runoff community, observation tracer agent goes out now and layer position first, thus calculates the flow velocity of interflow.
4th step.Throw in the moment with when lower end, runoff plots occurs according to tracer agent, calculate the time flowed through, then according to the tracer agent degree of depth of throwing in and the layer position going out stream, calculate the distance that tracer agent flows through, thus calculate the mean flow rate of different layers position interflow.
As shown in figure (5), if tracer agent release position is S, l
1, l
2, l
3, l
4represent that different depth tracer agent goes out flow path respectively, the time used is t (s), then the mean flow rate V (m/s) of interflow is:
V＝l/t
5th step.According to the run-off that different layers position is collected for every 5 minutes, be plotted in two-dimensional coordinate system (t represents the time, and y represents flow), just can draw the dynamic process of different layers position interflow.And adding up by each layer of position, draw the run-off of simple layer position.Finally the run-off of each layer of position is added up to, just drawn the interflow total flow in this rainfall.
6th step.Added up by the dynamic change of seasonal effect in time series, different layers position interflow, with single layer bit accumulation calculating, and the accumulation calculating of complete section face interflow, just (t represents the time can to obtain the space-time three-dimensional of interflow in this rainfall, z represents different layers position, and y represents flow) Changing Pattern---i.e. flow rule over time on different layers position.
7th step.By the flow velocity of calculated different depth interflow, combine with the space-time three dimensional change feature of interflow flow, just can carry out interflow Hydrodynamics Analysis.
Embodiment two: the mensuration of interflow flow velocity and interflow dynamic calculation under artificially-simulated rainfall condition
Because the raininess of natural rainfall easily fluctuates wayward, rainfall duration also can change, and sometimes chronic, the time is very short sometimes.Therefore, in decades, this research field studying slope runoff hydrodynamics process, generally all adopts the mode of artificially-simulated rainfall to carry out.
The first step.The same.
Second step.After slope runoff community and relevant tracer agent input facility 1 and interflow collection facility 2 are built and are installed, first, settle in the left and right sides, slope runoff community 4 (2, every side) pressure-controlled, two-way lateral spray type, portable artificially-simulated rainfall device (conventional used).According to test design, by pressure and shower nozzle pore size, control raininess, and set the rainfall duration of certain time length, thus play control raininess and total rainfall amount.Secondly.At slope runoff community outer ledge, gather pedotheque, the initial water content of testing soil.Then, rainfall start time is recorded.
From the 3rd step to the 7th step, the same.
Finally, it is also to be noted that what enumerate above is only several specific embodiments of the present utility model.Obviously, the utility model is not limited to above embodiment, can also have many distortion.All distortion that those of ordinary skill in the art can directly derive from content disclosed in the utility model or associate, all should think protection domain of the present utility model.
