Arizona Planning Guide for Natural Resource Concerns
Water Quality Degradation–Excess Sediment in Surface Waters
USDA Natural Resources Conservation ServicePage 1Arizona
Field Office Technical Guide, Section IIIJuly 2014
Resource Concern Description–Off-site transport of sediment from sheet, rill, gully, wind, and irrigation-induced erosion into surface water threatens to degrade surface water quality and limit use for intended purposes.
Planning Criteria–Land use and management does not cause accelerated erosion. Upslope treatment and buffer practices address concentrated flows to water bodies.
- Planning criteria for all applicable types of soil erosion are also met for this resource concern.
- Where applicable, SVAP2 bank condition element score is ≥ 5.
- Where applicable, livestock and vehicle water crossings are stable.
Methods for evaluating resource condition
- Visual assessment
- Volume calculations
- Rangeland Health Assessment
- Pasture Condition Score
- SVAP2
- RUSLE2
- WEPS
- Irrigation-induced Erosion worksheet
- WINSRFR
- Hillslope Erosion Model
