1. Evaluation of percent flow captured by a small in-field runoff collector

Author:
Franklin, D.H.; Cabrera, M.L.; Steiner, J.L.; Endale, D.M.; Miller, W.P.

Transactions of the ASAE 2001 v.44 no.3 pp. 551
ISSN:
0001-2351
Subject:
runoff; surface water; land management; water quality; water pollution; pollution load; nutrient management
Abstract:
... Increased environmental concern about nutrient loadings in runoff and surface water has heightened the need for evaluation of management practices at the field scale. Thus, there is a need for small in-field runoff collectors to assess nutrient migration at the field scale on various land management systems. A runoff sampler previously designed for the relatively flat terrain of the Coastal Plain ...

2. Stream nutrient retention in three northeastern Oklahoma agricultural catchments

Author:
Haggard, B.E.; Storm, D.E.; Tejral, R.D.; Popova, Y.A.; Keyworth, V.G.; Stanley, E.H.

Transactions of the ASAE 2001 v.44 no.3 pp. 597
ISSN:

Subject:
streams; water quality; watersheds; watershed hydrology; spatial variation; nutrient retention; seasonal variation; limnology; water pollution; aquatic environment; Oklahoma
Abstract:
... Stream nutrient retention was examined in three adjacent agricultural catchments (Cherokee Creek, Cloud Creek, and Dry Creek) in the Ozark Plateau. Retention efficiency was measured using short-term nutrient and tracer injections to estimate nutrient uptake length (S(w)) during summer 1999 and winter 2000. A one-dimensional transport model was used to estimate dispersion, transient storage size, a ...

3. Evaluation of AnnAGNPS on Mississippi Delta MSEA watersheds

Author:
Yuan, Y.; Bingner, R.L.; Rebich, R.A.
Source:
Transactions of the ASAE 2001 v.44 no.5 pp. 1183
ISSN:
0001-2351
Subject:
watersheds; crop production; crop management; cover crops; winter; pollution control; water pollution; erosion control; water erosion; sediment yield; simulation models; agricultural land; losses from soil; runoff; prediction; best management practices; nonpoint source pollution; Mississippi
Abstract:
... Sediment and its associated pollutants entering a water body can be very destructive to the health of that system. Best Management Practices (BMPs) can be used to reduce these pollutants, but understanding the most effective practices is very difficult. Watershed models are the most cost-effective tools to aid in the decision-making process of selecting the BMP that is most effective in reducing t ...

4. Seasonal occurrence and export of five herbicides from a North Carolina Coastal Plain watershed

Author:
Novak, J.M.; Watts, D.W.; Stone, K.C.; Johnson, M.H.

Transactions of the ASAE 2001 v.44 no.5 pp. 1201
ISSN:

Subject:
coastal plains; watersheds; herbicide residues; alachlor; ametryn; cyanazine; metolachlor; atrazine; herbicides; losses from soil; streams; water pollution; agricultural land; seasonal variation; North Carolina
Abstract:
... Herbicide detection in surface water sources has caused concern about contamination of these sources and adverse effects on human and aquatic health. Understanding surface water herbicide transport from agriculturally intensive watersheds is useful for development of herbicide best management practices to reduce off-site movement. The seasonal occurrence and load of five herbicides exported by a s ...
