Abstract |
The Direct/Delayed Response Project (DDRP) has been designed and implemented by the U.S. Environmental Protection Agency to estimate the number of surface waters (lakes, streams) in three regions of the eastern U.S. that might become acidic due to current or altered levels of acidic deposition. As part of DDRP, 36 watersheds in the Mid-Appalachian Region (Pennsylvania, West Virginia, western Virginia) were mapped at a scale of 1:24,000 for soils, vegetation, landuse, drainage system, and depth to bedrock. As was true in other DDRP regions, many more soils were identified during mapping than could practically be sampled. To facilitate sampling, the soils were grouped into 15 soil sampling classes. Each class has been sampled several times across the region. Because a randomized sampling design was used, regional means and standard deviations of soil properties can be computed for each class. The regional data will be combined with the soil maps to estimate soil properties for each watershed. The watershed estimates can then be used in the array of DDRP models to estimate future effects of acidic deposition on streams in the region. The soils identified during mapping were correlated and the sampling classes were defined at a workshop held in Corvallis, Oregon, Aug 22-25, 1988. The report documents the process and results of the workshop, and the post-workshop allocation of sampling effort to sampling classes and watersheds. |
