简介：
Overview
This study outlines the design and construction of a facility for measuring runoff from simulated urban lawns. It details the methods for collecting and analyzing runoff water samples for chemical constituents.
Key Study Components
Area of Science
- Environmental Science
- Hydrology
- Urban Ecology
Background
- Understanding runoff from urban lawns is crucial for environmental management.
- Runoff can carry various chemical constituents affecting water quality.
- Simulated lawns provide a controlled environment for study.
- Measuring runoff helps in assessing the impact of urban landscaping.
Purpose of Study
- To design a facility for measuring total runoff volumes from urban lawns.
- To collect runoff water samples for chemical analysis.
- To evaluate the effects of lawn management practices on runoff quality.
Methods Used
- Selection of a site with a uniform slope for the facility.
- Construction of retaining walls and collection troughs for runoff.
- Installation of measuring and sampling equipment below the retaining wall.
- Preparation of plot areas with irrigation and barriers to manage water flow.
Main Results
- Successful construction of a facility with 24 individual plots.
- Accurate measurement of runoff volumes over time.
- Collection of runoff water samples at selected intervals.
- Quantification of chemical constituents in the runoff water.
Conclusions
- The facility design effectively measures and collects runoff data.
- Findings can inform urban landscaping practices to minimize runoff pollution.
- This method can be applied to other urban environments for similar studies.
