Influence of gravel mulch on rainfall interception under simulated rainfall

Erodibility of road batters under simulated rainfall

Rainfall simulation experiments on road batters in a forest catchment in New South Wales, Australia, demonstrated the limits of small scale erosion studies. Comparable erodibility studies were carried out on road surfaces, road batters constructed of soil, bedrock and unconsolidated materials and the forest surfaces. There was no significant difference in sediment loss between any type of site,...

A Rainfall Interception Model for Alfalfa Canopy under Simulated Sprinkler Irrigation

Estimating canopy interception of water by plants during rainfall or sprinkler irrigation is a critical step for evaluating water-use efficiency. Most existing experimental studies and mathematic models of canopy interception have paid little attention to the interception losses of water by herbaceous plants. To better understand the canopy interception processes of herbaceous plants and to est...

Impact of Rainfall Microstructure on Erosivity and Splash Soil Erosion Under Simulated Rainfall

Rainfall Interception by Sacramento's Urban Forest

A one-dimensional mass and energy balance model was developed to simulate rainfall interception in Sacramento County, California. The model describes tree interception processes: gross precipitation, leaf drip, stem flow, and evaporation. Kriging was used to extend existing meteorological point data over the region. Regional land use/ land cover and tree canopy cover were parameterized with dat...

Investigation of Rainfall-Runoff Processes and Soil Moisture Dynamics in Grassland Plots under Simulated Rainfall Conditions

The characteristics of rainfall-runoff are important aspects of hydrological processes. In this study, rainfall-runoff processes and soil moisture dynamics at different soil depths and slope positions of grassland with two different row spacings (5 cm and 10 cm, respectively, referred to as R5 and R10) were analyzed, by means of a solution of rainfall simulation experiments. Bare land was also ...
