The source areas of headwater streams typically compose 60% to 80% of a catchment. This,
plus the typical increase in precipitation with elevation, means that headwater streams …

Nonpoint source pollution and hydromodification are the leading causes of impairment to
our nation's rivers and streams. Roadside ditch networks, ubiquitous in both rural and urban …

Spatially distributed nonpoint source (NPS) pollution indices are used to identify areas in a
watershed where potential pollutant loading coincides with runoff generating areas …

Roadside drainage networks can affect deleterious changes to watershed hydrology and
water quality. However, very few studies have explored these effects in agricultural settings …

We used a generalized likelihood uncertainty estimation procedure with the Distributed
Hydrology Soil Vegetation Model (DHSVM) for two streamflow and 11 road ditchflow …

In this study, we demonstrate that watershed-scale estimates of road sediment production
are improved if field measurements of road runoff and sediment production are used in the …

Poorly designed and maintained forest road stream crossings can directly link erosion
sources to streams. Forestry best management practices (BMPs) provide techniques that are …

Forest roads can be a source of accelerated erosion, which can be detrimental to aquatic
habitat, fish, and other aquatic biota. Erosion models are increasingly used to quantify …

Buffers, filter strips, and other riparian protection zones are widely accepted practices used
to minimize water quality impacts from forest management and other land use activities …

The prioritization of road maintenance projects is an important forest engineering task
subject to limited budgets and competing investment needs. Large investments are made …
