tutorial 2:Steady flow using Hec-Ras

how is it over there hope you're doing well today I want to start the new course about haircuts we start from beginner to advancing and in the first tutorial I share with you how you install the hekron software for free and I put the link in the tutorial in the description you can find it easily now we have this cross section as you see here two meter language is a bed with 6 meter and the Swedish 2 meter the height from the bottom to embankment is 3 meter we have two cross section and the link is between them 500 meter let's put this data into the aircraft and in the next tutorial we talk about real application and real example which solve it by haircross just to be familiar with the software we show you how you calculate the profile velocity fraud number and shows all the data regarding this channel it is open the across software that's hey class it appears like this double click from here first we have to create a new project new project from here you can determine the directory I selected disk e this file here class otherwise you can click folder new folder if you want I already could folder its name heygrass from here you can enter my title Channel 4y okay good second step we have to change the unit you see us customer unit we I want to change it to metric system from immune system select International System okay yes then click this icon from library you can click the reach double click OK arrive name it driver maybe this driver has its name but now there is no name so I just write arrive and Rich one okay and from cross section you can add a cross section here option add a new Option add a new cross section ID W1 DNA description cs1 how we can insert the data if you look at the cross section here is zero from left to right here is zero and from here is two it just we have to add X Direction here length 0 station 0 and elevation 3 meter from here links to 2 meter but elevation is three here elevation 0 but land guess is 8 meter two plus six eight here elevation is 3 and the language is 10. let's insert this data to the hair cross okay zero elevation three two elevation 0 8 elevation 0 10 elevation three from here Downstream Rich language from here to here how long it it is 500 meter 500 right Bank 500 Manning is value you have a man in this value for your channel but I here for left back I put 0.02 and for the channel always it's greater 4.023 is the 24 right Bank 4.0 2 they also a 0.02 okay Left Bank you have to add zero here zero left to right 10 meter apply the data you see your Channel here 0 to 2 2 8 8 10 and the elevation is 3 meter if we want to create another cross section just here from option copy current cross section here you have to add the ID to private Station 2 station 2. okay cross section two there should be a slope to flowing water so we add the difference between this cross section is three meter from option adjust elevation here at -3 meter okay you see how it change okay every data is correct to this cross section also apply data if you don't see your channel just from plot option full plot you can see your channel here it's the same geometry 2 to 8 10 and the elevation is three you see minus three to zero it's three is a h okay from tools interpolation with an RH here you can select it I selected all RS linear interpolation and the lengths of each segment I selected 50 meter we will get 10 segment just click interpolate close now we have a 10 segment if you count them okay we don't need this anymore yes from edit steady flow data we have to add flow break from here let me the QD shards 300 meter per second Bridge boundary condition for example in the second boundary in the second cross section we know the water surface let b 2 meter okay good you can save save flow data okay do it now we are ready just from run steady flow analysis here I delete B1 you select subscript subcritical supercritical mixed with isolated subcritical compute okay Saran is completed let's see the our result from here cross section also you can from here you can get but I directly get cross-section you see that's our cross section and also we get the different velocities velocity here as you see 1.09 velocity here 3.89 that is a velocity distribution within the channel and let's Energy Grade line it shows you what a surface that's what surface okay switch to the second cross section that's the second switch to the first one that is the first one if you want to see the profile from here you can see the profile this Energy Grade line this one water surface this one critical hate and just on the ground and also from table you can see all the data Q minimum Channel elevation water surface elevation for each station as you see is at the station one station 1.1 station 1.2 Energy Grade line shows energy grid line slope velocity is a channel flow area top with this fraud number you see it's subcritical okay that's all for today I hope it can be helpful have a nice time
