[1] The stream power erosion law, which describes the erosion rate as a function of channel discharge and gradient, has often been used for modeling landscape evolution in regions dominated by fluvial processes. However, most previous studies utilizing the stream power erosion law simply use drainage area as a surrogate for channel discharge. Despite its convenience this simplification has impo...

Understanding the intensity and duration of tropical rain events is critical to modelling the rate and timing of wetcanopy evaporation, the suppression of transpiration, the generation of infiltration-excess overland flow and hence to erosion, and to river responsiveness. Despite this central role, few studies have addressed the characteristics of equatorial rainstorms. This study analyses rain...

Rainfall patterns and land cover are two important factors that affect the runoff generation process. To determine the surface and subsurface flows associated with different rainfall patterns on sloping Ferralsols under different land cover types, observational data related to surface and subsurface flows from 5 m × 15 m plots were collected from 2010 to 2012. The experiment was conducted to as...

Numerous studies have investigated future changes in extreme precipitation by employing climate models. However, trends short-duration (20–180 min) rainfall intensities, that is, design storm intensities used for stormwater infrastructure design, received considerably less attention despite their importance. This study quantified the effect of change on intensity based observations. Trends were...

This work presents a determination method of rainfall types based on rainfall-induced slope instability to provide an effective approach for early warning different patterns failures/landslides. Firstly, 5808 scenarios are simulated with 11 kinds soil properties under 528 designed intensity-duration (I?D) conditions get the threshold curves failure and properties. Then through analysis when occ...

Urban stormwater with large impervious (paved) areas often produces runoff with a variety of contaminants. Although southern California is among the most urbanized coastal areas in the United States, the effect of rainfall variations on washoff efficiency of contaminants from pervious and impervious surfaces is largely unknown. The goal of this study was to investigate the effect of varying rai...

[1] This work quantifies and explains the direct physical effects of slope angle on infiltration and runoff generation by extending the Green-Ampt equation onto sloping surfaces. A new extended solution using identical precipitation hydrographs was compared to the original formulation and then used to calculate the infiltration and runoff generation for different slope angles but for identical ...
