SCS or NRCS Curve Number (CN) Method - Introduction

[@suseendar]

Beautifully explained , your lecture covers both theoretical and practical applications of hydrology. I found it much useful in 2D flood mapping where we have zero available data.

[@amisourov2304]

very well explained. Loved it. Good wishes

[@peterokitoi7757]

Could you make a video on the different hydrological methods and when best to use them for analysis like you did for this video of SCS ? Thanks

[@hydrologyvideos8253]

coming in the future!

How can i get the CN for my area if i have just the landuse ?

[@beingyourself818]

Is there any tutorial for surface runoff estimation using qgis

[@knowlege2024]

it is very informative. but the soil as usually we get from FAO, the hydrological group is not given but the soil type is given such as loam, clayey etc. do you have any table in which soil type and their infiltrations rates are known?

this tutorial (little old) may be useful: web.ics.purdue.edu/~vmerwade/education/fao_soil_tutorial.pdf

[@hydrologyvideos8253]

You need land use and soil data to get CN for your area.

[@hydrologyvideos8253]

@@fratacet9968 yes. Use this tutorial: web.ics.purdue.edu/~vmerwade/education/qcngrid.pdf

How to get land use data?

[@hydrologyvideos8253]

It depends on the area that you are interested in. For US, you can use national land cover dataset. Google NLCD

@@hydrologyvideos8253 my area is near elephant butte dam reservoir in New Mexico,can you tell me where I can get data

[@hydrologyvideos8253]

@@Deocy19 get landuse data from NLCD and soil data from gSSURGO. google these names to get the data.

[@peterokitoi7757]

And for guys outside USA, what’s our go to, to get land use and soil data
