Calculation template for the unit-scale framework for designing step-pool sequences

This is the calculation template for the manuscript titled "A unit-scale framework for designing step-pool sequences" by Chendi Zhang, Marwan A. Hassan, Matteo Saletti, André E. Zimmermann, Mengzhen Xu and Zhaoyin Wang. The design method described in the manuscript is specifically for river restoration using artificial step-pool sequence (Zhang et al., 2018, 2020; Zimmermann et al., 2020). Version 1.0 of the calculation template was applied to a total of 21 artificial step-pools built in the Maso di Spinelle River in Italy (Lenzi 2002; Lenzi and Comiti 2003; Comiti et al. 2009). A natural step-pool sequence including 20 units in the Erlenback in Switzerland (Golly et al., 2019) was used in the Version 2.0 of the template. The instructions are included in the file. With changes in the inputs, this template can also be used for other cases where design for artificial step-pools is needed. The flow competence estimation method (Richardson and Carling, 2021) has been incorporated in the Version 2.1.
