Effects of Frozen Soil on Snowmelt Runoff and Soil Water Storage at a Continental Scale
The presence of ice in soil dramatically alters soil hydrologic and thermal properties. Despite this important role, many recent studies show that explicitly including the hydrologic effects of soil ice in land surface models degrades the simulation of runoff in cold regions. This paper addresses this dilemma by employing the Community Land Model version 2.0 (CLM2.0) developed at the National C...
متن کاملPhosphorus runoff from two water sources on a calcareous soil.
Phosphorus (P) in irrigation runoff may enrich offsite water bodies and streams and be influenced by irrigation water quality and antecedent soil surface conditions. Runoff, soil loss, and P fractions in runoff using reverse osmosis (RO) water or mixed RO and well water (RO/ Tap) were studied in a laboratory sprinkler study to evaluate water source effects on P transport. A top- or subsoil Port...
متن کاملRelating soil phosphorus to dissolved phosphorus in runoff: a single extraction coefficient for water quality modeling.
Phosphorus transport from agricultural soils contributes to eutrophication of fresh waters. Computer modeling can help identify agricultural areas with high potential P transport. Most models use a constant extraction coefficient (i.e., the slope of the linear regression between filterable reactive phosphorus [FRP] in runoff and soil P) to predict dissolved P release from soil to runoff, yet it...
متن کاملEffects of Rainfall and Runoff Variables on Phosphorus Loss in a Forest Watershed, Iran
Suspended sediment resulted from distributed soil erosions facilitates nutrient transportation and influences soil depletion. Phosphorus (P) is one of the major limiting nutrients controlling eutrophication of surface water. Irregular P load pulsed by heavy rainfall may damage the ecological quality of downstream waters. P transport study during rainfall events is important in both predicting a...
متن کاملImpacts of Organic Soil Amendments on Runoff and Soil Ero- Sion under the Natural Rainfall Conditinos, Preliminary Re- Sults
Organic amendments such as composts and mulches have been shown to improve soil quality and reduce the impacts of stormwater runoff and soil erosion Previous studies using rainfall simulators have documented that runoff volumes and soil erosion can be significantly reduced when organic materials are added to the soil profile. The objectives of this study are to measure the changes in runoff and...
