From 2330152080 at qq.com Wed Apr 26 03:59:22 2023 From: 2330152080 at qq.com (=?gb18030?B?MjMzMDE1MjA4MA==?=) Date: Mon Mar 18 20:05:52 2024 Subject: [Dhsvm-users] The result of DHSVM model Message-ID: Hello: I am using the DHSVM model to simulate watershed runoff, but the results are relatively poor now. I adjusted some parameters that are acknowledged to be sensitive to the model results, but the results are still poor. The results are shown in the figure below. The orange solid line is the simulated value and the blue is the measured value. The fluctuation of simulation results is small, which can not capture the peak runoff well. I hope you can give me some advice. Thank you very much. If you need more information, please let me know.

I would start with your climate forcings and soil parameter values. Are you using station data for climate?

I?m using station data for climate, so I think the meterological data should be free of major erorrs. I modified soil parameters such as lateral conductivity and field capacity according to your suggestions, and the accuracy of the model was indeed improved. But the results of simulation still could not capture the peak of runoff well. The observation runoff fluctuated a lot and had a large range of changes, while the simulation runoff had fewer fluctuations and a small range of changes. The simulation runoff fit well with the trend of precipitation data, but not well with the observation runoff, especially in August. ------------------ Original ------------------ From: "dhsvm-users" -------------- next part -------------- A non-text attachment was scrubbed...
