Raw data for the channel widths and slopes

Spatio-temporal variations on alluvial fan channel width in response to grain size on the channel bed under constant upstream boundary conditions<b>.</b>This dataset pertains to the alluvial fan tank experiment conducted at the University of Minnesota, Delta Basin-1. The experiment was designed to study the dynamics of alluvial fan formation under controlled conditions, specifically focusing on the following parameters:Experimental Conditions:Constant Upstream Boundary Condition: The experiment maintained consistent inflow rates throughout the duration of the study.No Base-Level Change: The experiment was conducted without altering the base level, allowing for the observation of sediment transport and deposition solely due to inflow dynamics.Sediment Mixture: The sediment used in the experiment consisted of:50% Crushed Walnut Sediment: diameter ranging form 0.149 to 0.40 mm, density of 1.3 g/cm³.50% Quartz Sand: diameter ranging form 0.075 to 0.090 mm, density of 2.65 g/cm³Flow Rates:Low Qw (LQw): 7 × 10⁻⁵ m³/sec (low water flow rate)High Qw (HQw): 10 × 10⁻⁵ m³/sec (high water flow rate)Low Qs (LQs): 2 × 10⁻⁶ m³/sec (low sediment flow rate)High Qs (HQs): 4 × 10⁻⁶ m³/sec (high sediment flow rate)<br>
