One-line model description Simulate detachment limited sediment transport.
Extended model description Landlab component that simulates detachment limited sediment transport is more general than the stream power component. Doesn't require the upstream node order, links to flow receiver and flow receiver fields. Instead, takes in the discharge values on NODES calculated by the OverlandFlow class and erodes the landscape in response to the output discharge.

As of right now, this component relies on the OverlandFlow component for stability. There are no stability criteria implemented in this class. To ensure model stability, use StreamPowerEroder or FastscapeEroder components instead.

       K_sp : float, optional
           K in the stream power equation (units vary with other parameters -
           if used with the de Almeida equation it is paramount to make sure
           the time component is set to *seconds*, not *years*!)
       m_sp : float, optional
           Stream power exponent, power on discharge
       n_sp : float, optional
           Stream power exponent, power on slope
       uplift_rate : float, optional
           changes in topographic elevation due to tectonic uplift
       entrainment_threshold : float, optional
           threshold for sediment movement
       slope : str
           Field name of an at-node field that contains the slope.
