Herbaceous biomass, harvested and handled as hay, has potential for bioenergy production. In the Upper Southeast, fields that cannot be competitively managed to produce another crop can produce an acceptable yield of switchgrass. Using a delayed harv

Nonpoint-source (NPS) or diffuse pollution is a major environmental problem in developed countries, and modeling is an important tool used to evaluate the effectiveness of pollution control measures. The use of NPS models in the tropics usually invol

Incorporating variability in soil and chemical properties into root zone leaching models should provide a better representation of pollutant distribution in natural field conditions. Our objective was to determine if a more mechanistic rate-based mod

Fecal coliform TMDL plans for five impaired segments were developed in the 388 square mile Big Otter River (BOR) basin in Virginia. These stream segments are Sheep Creek, Elk Creek, Machine Creek, Little Otter River, which are tributaries of the BOR,

Calculation of fecal coliform source loads for TMDL development can be both tedious and timeconsuming. However, these source loads are the main fecal coliform inputs to the HSPF model, and accurate estimation of these loads is crucial. Both daily and

The emphasis on a watershed-scale approach to management of water quantity and quality has renewed the focus on hydrologic/water quality modeling at that scale. While the most widely used modeling approach to TMDLs continue to be a lumped approach us
