Statement

Observed stream discharge data per unit micro-basin area (mm/15min) were modelled from observed rainfall data from a single raingauge within the micro-basin (mm/15min). The simulated discharge time-series (mm/15min) was modelled using the RIVSID algorithms of the CAPTAIN Toolbox (https://wp.lancs.ac.uk/captaintoolbox) that represent dynamics in the form of Transfer Functions. RIVSID is an abbreviation of ‘Refined Instrumental Variable System Identification’ algorithms. These algorithms are available for optimal RIV estimation of multiple-input, discrete-time and hybrid continuous-time Transfer Function models. Details of how to use RIVSID within the Matlab programming environment are given at: https://eprints.lancs.ac.uk/id/eprint/86904/4/CAPTAIN_Getting_Started.pdf. The derived Transfer Function characteristics, sometimes called ‘Dynamic Response Characteristics’ or DRCs, of Time Constant, Steady State Gain and Pure Time Delay. The Time Constant is the transfer time of the propagating flood wave (i.e., celerities) through the catchment (Cheng et al. 2023. Water Resources Research, 59: e2022WR033625, https://doi.org/10.1029/2022WR033625 ). The Steady State Gain a rainfall-runoff system is simply the simulated runoff coefficient (Chappell et al., 2006. For. Ecol. Manage. 224, 58-80, https://doi.org/10.1016/j.foreco.2005.12.008 ). The Pure Time Delay in simple terms is the time between a rainfall input and the first discharge response (Chappell et al., 2012. IAHS Publication 353, IAHS Press. 82-93, http://iahs.info/redbooks/a353/iahs_353_0082.pdf ). Full and complex explanation of the Transfer Function identification is given within Box, G.E.P, Jenkins, G.M. and Reinsel, G.C. 2008. Time Series Analysis. John Wiley and Sons, pp746. For the specific application of RIVSID, each discharge hydrograph event was modelled separately. The characteristics of each simulated discharge hydrograph were then derived from the simulated stream discharge data per unit micro-basin area (mm/15min) also within the Matlab programming environment. For fine technical details of how RIVSID was applied to the specific micro-basins, please see Mindham, D., Beven, K. and Chappell, N. 2023.
