Bedrock fracturing, threshold hillslopes, and limits to the magnitude of bedrock landslides
a r t i c l e i n f o Keywords: bedrock fractures threshold slopes landslides landscape evolution erosion Bedrock fracturing and rock strength are widely believed to influence landscape morphology and erosional resistance. Yet, understanding of the quantitative relationship between rock-mass strength and landscape evolution remains limited. Here we present a new application of seismic refractio...

متن کاملControls and limits on bedrock channel geometry
[1] Data on channel geometry in naturally incising bedrock rivers reveal variable relationships between channel width, slope, and erosion rate. To explain the range of relationships between these parameters, we propose an optimized channel geometry model. The model reproduces previous theoretical and numerical modeling scaling relationships; however, to explain the field data, the model must in...
متن کاملQuantifying bedrock‐fracture patterns within the shallow subsurface: Implications for rock mass strength, bedrock landslides, and erodibility
[1] The role of bedrock fractures and rock mass strength is often considered a primary influence on the efficiency of surface processes and the morphology of landscapes. Quantifying bedrock characteristics at hillslope scales, however, has proven difficult. Here, we present a new field‐based method for quantifying the depth and apparent density of bedrock fractures within the shallow subsurface...
متن کاملAn analytical model for hydraulic fracturing in shallow bedrock formations.
A theoretical method is proposed to estimate post-fracturing fracture size and transmissivity, and as a test of the methodology, data collected from two wells were used for verification. This method can be employed before hydrofracturing in order to obtain estimates of the potential hydraulic benefits of hydraulic fracturing. Five different pumping test analysis methods were used to evaluate th...
