As of 1998 over 290,000 miles of river, almost 7,900,000 acres of lake and 12,500 square miles of estuaries failed to meet water quality standards. Military training maneuvers have the potential to significantly alter land surfaces in a manner that promotes NPS pollution, resulting in the inability of military installations to meet water quality standards and the decline of training lands. Real-Time Sediment Load Sensor Upstream TRAINING INTENSITY + WEATHER + LAND COVER + SOILS + TOPOGRAPHY Input training records in GIS database. Collect environmental GIS data. Run watershed water quality model. Answer the following: Very Low Low Moderate High Very High Given non-frozen soils, mean soil moisture of 23%, and projected vegetation damage (from historical data), what is the potential to generate NPS pollution given a 5 day mechanized infantry battalion force-on-force exercise to be held in training areas A-H?” Riparian Buffer Study Runoff Collection Sump Upland Maneuver Area Military readiness depends upon high quality training. Effective maneuver training requires large areas of land and creates intense stress on this land. Environmental protection requirements place additional restrictions on land use and availability. Because military training schedules are set well in advance to make the best use of installation training facilities and National Training Centers, there is little flexibility to modify training events and maintain readiness. In order to avoid maneuver restrictions, proactive management plans must be developed giving commanders the information they need to assess the environmental cost of training and management practices that reduce the environmental impact. Turbidity Sensors The objective of this work, funded through CP1339 (Characterizing and Monitoring Non-point Source Runoff from Military Ranges and Identifying their Impacts to Receiving Water Bodies) is to identify sources of NPS pollution resulting from military activities, assess the impact of this pollution on surface water quality, and provide information for commanders to lessen the impact of training on water quality. Investigators are assessing the impact of two major sources of NPS pollution on surface water quality at Fort Riley, Kansas: (1) erosion from upland training areas and (2) channel erosion at stream crossing sites. Project objectives will be met through a comprehensive analysis of military activities, climatic factors and environmental response. Researchers are using watershed water quality models in conjunction with remotely sensed information and a geographic information system (GIS) to assess the impact of training on water quality, in particular on the amount of soil erosion. A matrix of training intensity and weather will be created for assessing the environmental cost of training maneuvers. In addition, researchers are collecting surface runoff at three buffer sites to determine the effect of vegetated buffers for controlling NPS pollution and using new real-time data collection systems to assess the impact of vehicle crossings on stream water quality and erosion dynamics at Low Water Stream Crossings (LWSCs).
