"Our company, Aqua Ingenieria (Puerto Montt, Chile) is dedicated mainly to the development of projects in the Hydraulic and Sanitary area, such as: Hydrological studies, hydraulic work, river modelling, outdoor and indoor potabilization water projects, along with the design of sewage systems. We work mainly with real estate, architectural companies, aquaculture industry and within the private sector in general. We found HEC‑RAS software very unfriendly and rigid, does not allow to erase any mistakes, and everything is done based on tables, which makes the system tedious and slow, and when you have a river of a big length much of the time is spent building up the model. On a frequent basis, I design water intakes for the aquaculture industry, and the National Water Authority requests these type of projects need to be designed in such a way the new civil work is guaranteed to be free of any risk of floods within the vicinity, so I have to build together a model of the river showing off the situation before the project and also with the water intakes. Before, this process could take me a whole day, but now with GeoHECRAS software I can do it in a couple of hours some 50% to 60% less time I believe. What I like most is that the core point relies on the fact that everything is done based on a drawing interface, without having to manually enter data. I’d recommend GeoHECRAS to anybody as its friendly interface is very easy to learn and has everything that one as an engineer needs to be able to perform within river modelling. Last but not least, I’ve had no problem with the technical support, they are always in contact to see how the projects are doing and asking if I need more help."
