Subject: Calibration daily model Posted: 2/9/2022 Viewed: 2259 times
I have calibrate and validate (with a very good indicators (Moriasi et al 2007)) mensual hydrological model in a pyrenean valley using soil moisture method. However now I transform this mensual model into a daily model. Therefore I have started with a new calibration process. However it seems no posible to calibrate. I have a very extrems flow peaks and at the same time a very small baseflows. So the model it seems having extreme reactivity. I have tried to decrease RRF and RSC values, and also I have decreased preferred flow directions values, but it doesn't work. I also used PEST calibration but it not helps: results doesn't not improved, and sometimes PEST simple doesn't work.
