Research at Walnut Creek The Walnut Creek Watershed at the Iowa MSEA site provides an opportunity for scientists to study the complex interaction of soils, weather, water, agrichemicals, hydrogeology, economics, and farm management systems.
The Walnut Creek Watershed is an intensively farmed 18 square mile area south of Ames, Iowa. Long-term monitoring of a watershed with intensive row crop production and little animal agriculture will provide a baseline of crop production impacts on surface water quality.
The LSNT N management system will be applied to a subbasin within Walnut Creek and compared to two companion subbasins by a Iowa - Walnut Creek watershed book watershed approach.
The Walnut Creek Watershed is located in western Polk and eastern Dallas counties in central Iowa. The 53, acre landscape is rapidly changing, with over six-square miles being developing between The creek itself is a primary source for the metro area drinking water, joining up with the Raccoon River just above Des Moines Water Works.

Also posted here is the presentation about the plan that was given in January and February to member governments of the Walnut Creek WMA. Using the Comprehensive Economic and Environmental Modeling System (CEEPES), this paper evaluates six alternative sustainable agricultural policies at the Iowa MSEA site, Walnut Creek.
CEEPES is an integrated modeling system capable of evaluating the economic and environmental consequences of alternative policies affecting pesticide use. The Midwest Region of the United States produces 80% of the nation's corn and soybeans and is a primary user of fertilizers and pesticides. The impact of corn-soybean farming systems on water resources in the region is a concern, and as part of the President's Water Quality Initiative, the Management Systems Evaluation Areas (MSEA) Program was established in Iowa, Minnesota, Cited by: Delin, G.N., and Landon, M.K.,Effects of focused recharge on the transport of agricultural chemicals at the Princeton, Minnesota Management Systems Evaluation Area--Preliminary results, in Agricultural Research to Protect Water Quality--Proceedings of the Conference, Minneapolis, Minn., FebruaryAnkeny, Iowa, Soil and Water.
Dec 01, · Abstract Soil respiration is an important component of the carbon dynamics of terrestrial ecosystems. Many factors exert controls on soil respiration, including temperature, soil water content, organic matter, soil texture, and plant root activity.
This study was conducted to quantify soil respiration in the Walnut Creek watershed in central Iowa, and to investigate the factors controlling Cited by: western United States.
Within this program, Management System Evaluation Areas (MSEAs) were selected as research sites for study of the complex inter-actions of soils, weather, water, and farm management systems.

Sincethe watershed has been intensively monitored for flow, sediment, nitrogen and pesticide losses as part of the Management Systems Evaluation Areas Program. Topography of the watershed is relatively flat, and soils are poorly.

Ground-water levels and flow at selected study sites in the Walnut Creek Management System Evaluation Area, Boone and Story counties, Iowa. Nine sites within the Walnut Creek watershed basin near Ames, Iowa, were investigated with the U.S. Army Engineer Waterways Experiment Station Site Characterization and Analysis Penetrometer System (SCAPS).
The SCAPS performed soil classification and stratigraphy with the conventional cone penetrometer. Electrical resistivity measurements were made at two sites with the penetrometer Author: Landris T Lee, Jeff F Powell. ARS Benchmark Watershed Studies About the Studies.
In 14 benchmark watersheds, the Agricultural Research Service (ARS) is conducting in-depth studies that will help to validate physical-process models used for the National Assessment component of the Conservation Effects Assessment Project (CEAP).

The Walnut Creek, IA Watershed in Central Iowa near Ames began to be monitored for water quality and quantity in as a study site for the Management Systems Evaluation Area (MSEA) program. Representative of a large portion of the Midwest Corn-Soybean Belt, this area is a geologically young landscape with glacial till soil parent material.
Project Methods The modified watershed simulation model, SWAT, will be evaluated vs. the measured water flow and chemical concentration data from Walnut Creek, Story Co., IA to explicitly calculate the impact of extensive subsurface tile drainage systems on pesticide fate and movement. The model will be used to compare to the four year LSNT experiment that was conducted in WCW.
