When you construct your sim = flopy.mf6.MFSimulation()
gwf = flopy.mf6.ModflowGwf(sim, modelname="my model", save_flows=True)you can also get a list of the unique record names in your budget file by calling cbc = gwf.output.budget()
rec_names = cbc.get_unique_record_names() |

For example, I know the river leakage may be stored in But how can I visualize the number above? I'm really struggling on this :( |

For Modflow 2005 based models, the parameter riv = fp.modflow.ModflowRiv(sim,
ipackcb=53,
stress_period_data=stress_period_data)As far as visualization is concerned, you can get budget output as a 3d array and then plot it using FloPy's import matplotlib.pyplot as plt
leak = cbc.get_data(text="RIV", totim=times[-1], full3D=True)
pmv = flopy.plot.PlotMapView(model=gwf, layer=0)
pc = pmv.plot_array(leak, masked_values=[0,])
plt.colorbar(pc)
plt.show() |

Thank you for your reply! I tried the code above, but got an error as:
Then I checked the How can I fix it? |

The array looks like it's being returned within a list (ie. 4D, with time as the outer dimension). If you remove the time dimension as such you should be able to plot this: leak = leak[0]
pc = pmv.plot_array(leak, masked_values=[0,]) |

Thank you so much. It works! I see in some literature the analytical flow pattern is often used to represent river-aquifer interactions (see the figure below for example). Using flopy, how can I plot such an analytical figure? |

Hi all,
Following a previous discussion (#1704), I added a river object to the model. The river model is built as:
#adding riverriv_row = [0,1,1,2,3,3,4,5,6,6,7,8,9]riv_col = [4,4,5,5,5,6,6,6,6,7,7,7,7]riv_len = delr #river lengthriv_wdt = delc #river widthriv_bdp = 10. #river bed depthriv_bk = 5e-5 #hydraulic conductivity of river bedriv_rbot = 4 #river bottomriv_cond = riv_bk*riv_len*riv_wdt/riv_bdp #conductance of the riverbed material#stress period 1riv_sp1 = []stage_sp1 = 10 #river head at stress period 1for inum in range(len(riv_row)):riv_sp1.append([0, riv_row[inum], riv_col[inum], stage_sp1, riv_cond, riv_rbot])print("Adding ", len(riv_sp1), "Stages for stress period 1.")#stress period 2riv_sp2 = []stage_sp2 = 12 #river head at stress period 1for inum in range(len(riv_row)):riv_sp2.append([0, riv_row[inum], riv_col[inum], stage_sp2, riv_cond, riv_rbot])print("Adding ", len(riv_sp2), "Stages for stress period 2.")stress_period_data = {0: riv_sp1, 1: riv_sp2}#create river objriv = fp.modflow.ModflowRiv(sim,ipackcb = 1,stress_period_data = stress_period_data)The model is run successfully but I tried to extract the river leakage and flow lower face from the budget file, they cannot be found by the code I use (see below). I wonder is this because the river model was not added to the simulation, or some other reason (wrong post-processing code for example)?
The processing code I use is:
cbbobj = fp.utils.CellBudgetFile("./toy_tvar_mf05/modflowtest.cbc")times = cbbobj.get_times()leak = cbbobj.get_data(text = "RIVER LEAKAGE", totim = times[-1])[0]face_lower = cbbobj.get_data(text = "flow lower face", totim = times[-1])[0]The error information is:

I'm very much appreciated for your kind help!
