### Hello, I’m running the 3.11.0 model for urban flood risk mitigation model problem, I don’t know that to do because my Soil Hydrologic Group data only 3, 4, 13 and 14 but then the model needs only values 1-4, and I really don’t know what to do. 2022-10-28 15:44:53,310 (natcap.invest.utils) utils.prepare\_workspace(162) Level 100 Writing log messages to [C:\Users\63916\Documents\ArcGIS\thesis 3\InVEST-natcap.invest.urban\_flood\_risk\_mitigation-log-2022-10-28–15\_44\_53.txt] 2022-10-28 15:44:53,310 ( **main** ) cli.main(475) Level 100 Starting model with parameters: Arguments for InVEST natcap.invest.urban\_flood\_risk\_mitigation 3.11.0: aoi\_watersheds\_path F:\Downloads\Shapefils\Map\City\_of\_Marikina.shp built\_infrastructure\_vector\_path curve\_number\_table\_path F:\Downloads\CSV.

Welcome to the forums @r4mle ! This more recent error: **ValueError: The biophysical table is missing a row for lucode(s) [10]** is reporting something different, which is that your biophysical is missing an entry for lucode `10`. Could you check your biophysical table and make sure that there’s an entry for lucode 10? Also feel free to attach your biophysical table here if you’d like and we’ll be happy to take a look.

Hello, I already have the results thank you for helping I have more question, the value needed for the Rainfall Depth, is that annually or monthly? ---

@r4mle it really depends on the storm you’re trying to model (the “design storm”). From the [user’s guide appendix:](https://storage.googleapis.com/releases.naturalcapitalproject.org/invest-userguide/latest/urban_flood_mitigation.html#depth-of-rainfall-for-design-storm) > Depth of Rainfall for Design Storm > > A design storm is a hypothetical rainstorm used for modeling purposes. The design storm precipitation value should be chosen according to the area and goals. For instance, it could be the average precipitation per rain event, the precipitation at a certain percentile, or the maximum precipitation expected to occur once in 100 years. > > To calculate the design storm, users can look up intensity-frequency-duration (IFD) tables available for their city. The storm duration is equal to the average time of concentration of the studied watersheds. Time of concentration can be derived from existing studies or from web tools: eg. [Watershed Time of Concentration](https://www.lmnoeng.com/Hydrology/TimeConc.php). See Balbi et al. (2017) for a detailed description of these methods. Hope this helps, James ---

Thank you for the information. It helped me a lot. Another question is that, is that normal to the model that high runoff retention is low in flood volume and vice versa? How can I interpret this? ---

> [@r4mle](#): > > Another question is that, is that normal to the model that high runoff retention is low in flood volume and vice versa? Yes, runoff retention has an inverse relationship with flood volume (also referred to as runoff volume). The more runoff that is retained by vegetation or other landcover types, the less flooding will occur. ---

Thank you so much! I was just confused by the flood volume. I thought it should be direct proportional. But anyways, thanks for the information! ---
