Guidelines for Surface Water Drainage Plan for a Municipal Solid Waste Facility - Quiz

Quiz Question

1. In order to properly evaluate the effects of changes in the magnitude of peak flows, you should consider the timing of peak flows from the site and their contribution to peak-flow rates in receiving streams or channels.
True
False
2. The peak flow can be controlled by detention pond volumes, they are a function of the area draining to a discharge point, as well as the amount of precipitation losses for a given design storm.
True
False
3. A _________________________ site is a characteristic description of a proposed municipal solid waste site that has a natural condition or an undeveloped condition.
Red field

True
False
7. In analyzing the natural condition of sites where there has been no prior landfill development (green field sites), the appropriate comparison should be between the condition at the time the application is filed and the post development condition.
True
False
8. The ________________ condition is defined as the condition of the drainage pattern – at the time the application is submitted reflecting any previous development activities on the tract that may have changed the natural drainage patterns.
Predevelopment
Post development

True
False
11. Direct runoff methods were developed for a network of relatively large drainage subareas.
True
False
12. The purpose of detention ponds in landfill drainage design is to accommodate and attenuate excess rainfall, and to provide a controlled release of that rainfall.
True
False
