We developed a coupled hydrological-agro-economic modelling system to optimize irrigation strategies for a typical rice irrigation system in Central Vietnam (Quang Nam province). The model consists of a fully distributed hydrological model, which simulates the inflow to a reservoir, and an agro-economic model, which optimizes the rice irrigation technology, i.e. Alternate Wetting and Drying (AWD) or Continuous Flooding (CF), and -schedule under given water constraints. Irrigation strategies are derived based on different initial reservoir water levels at the beginning of the cropping season as well as different maximum water releases.
In order to publish our results we need to validate our modelling results. This seems to be a big problem since nearly no written information is available. We interviewed local stakeholders, which confirmed that our results are plausible, however, the reviewers are not convinced and demand for a "real" validation.
There is no time and money to conduct own field experiments. Therefore, we are looking for data about irrigation water requirement, number of irrigation events, irrigation interval, area that can be cultivated etc. for irrigation schemes under AWD and/or CF, preferably but not exclusively for Central Vietnam, in order to check our results.
Also, such data or even similar studies in the East Asian context could be helpful.
Any help on that is highly appreciated! Patrick
Hi Patrick. I have some relevant data for VGTB and Thach Han Basin (next basin to the North). They are unfortunately in Vietnamese only, however Google Translate could be already enough for understanding the tables and figures. I will send them to you per Email.
Dear Quang Dinh Duong,
this would be wonderful if you can share these data with us. The language is no problem at all, because the VN PhD student Thinh Dang works on this topic.
Do we know each other from the LUCCi project? Are you in Prof. Stolpe's group?
Cheers, Patrick
not yet, Camilla. Certainly worth to contact them.
Thanks for all answers.
Patrick
