Re: rRoot (T-level)/Transp (Meteo_out)

The rRoot (1900 mm) and Transp (1400 mm) values ​​are cumulative transpiration for one year. I summed all the transpiration for 1 year and those are the results. Through Hydrus, I have tried to find out how much water the pine transpires in a year. But my question is if there can be differences betw...

Re: rRoot (T-level)/Transp (Meteo_out)

Sorry, I was wrong in the Transpiration values.
In the case of rRoot, the result is 1900 mm but in the transpiration of Meteo_out it is 1400 mm. I wanted to understand why the values are different.

Thanks Jirka.

rRoot (T-level)/Transp (Meteo_out)

Hello, I hope you are well. I´m using hydrus1d to simulate pine evapotranspiration. I inserted in the hidrus LAI and meteorological data. Hydrus calculated PET (Penman.Monteith). My question is: I don't understand why rRoot (T-level) and transpiration (Meteo_out) are so different if they are both po...

Re: Storage of probe

Maybe, I didn't express my question correctly. I want to know how to calculate the "Storage of water in the soil" ... I know that the storage of water in the soil is an integral part of the volumetric content of water in depth. But for example, I have an observation node at 30 cm, and another at 50 ...

Storage of probe

Hi,
I have a question. I want to compare the water storage between the simulation of "hidrus" and the actual measurement of the probe. So, I want to know what the methodology for "water storage in the soil".
I didn´t find more details in hydrus manual.

Eto Penman monteith vs Eto Hargreaves

Eto Hargreaves and Eto Penman Monthei Hello, I write because I had a doubt. I have been using hydrus 1d and to estimate the eto, use the part of hydrus that allows you to estimate the eto according to Penman monteith. Use hydrus in centimeters and per hour. When I enter the data it asks me to calcul...

Precipitation interception / root distribution

Hi, I am using hidrus to estimate the water consumption of pinus radiata at 35 ° south latitude (Chile). I have some questions. 1. Precipitation interception: I am using the model from Von Hoyningen-Hüne [1983], Braden [1985] and van Dam et al. [1997]. I wanted to know how I can calculate parameter ...
