Acru model calibration

WebThe ACRU hydrological model, developed by Schulze ( 1995 ), is a daily time step process-based model with a multi-soil-layer water budget, which is sensitive to land management and changes thereof, as well as to climate input and changes (Smithers and Schulze 1995, Smithers et al. 1997, Schulze and Perks 2000 ). WebApr 27, 2024 · Model parameter calibration is based on both the optimization algorithm SCE-UA and artificial adjusting, by using a combined objecting function of flood peak, volume and process. Each model singles out a set of optimal parameters as input to simulate the design flood process.

WebOct 4, 2024 · Calibration methods There are at least a couple of methods you can calibrate your model with. The most popular ones remain to be Platt scaling (also known as the sigmoid method) and isotonic regression, although some other alternatives are possible (for instance the tempered version of Platt scaling). WebSep 5, 2024 · The ACRU CS model was used to validate the peak discharge estimates derived from surveyed flood lines and hydraulic calculations (Van Bladeren and Van der Spuy, 2000), i.e., since the exceptional flooding resulted in the failure and destruction of several gauging stations (Van Biljon, 2000) and therefore no observed flow data was …

WebACRU is a multi-purpose, multi-level, integrated physical-conceptual model that is designed to simulate total evaporation, soil water and reservoir storages, land cover and abstraction impacts, snow water dynamics and streamflow at a daily time step (Fig. 1).
