Figure 3. Concept model of fully penetrating stream with no stream bed resistance. The results from the 3D model for days of pumping are shown in Figure 4. To test the accuracy of the 3D model, the analytical solution of Hunt's model was also given in the figure. It is noticeable from Figure 4 that the results from the 3D model agree well with those of the analytical solution.
Figure 4. The whole computing area is about The recharge in the area is about The outer boundaries are represented by no-flow boundaries in the regional model, as shown in Figure 5. Figure 5.

To further acquire accuracy of the model in regional scale, a relationship, as shown in Figure 6 , of groundwater levels obtained by the model and by observation from the monitoring wells of the MDEQ's database was established. As indicated in Figure 6 , the root mean square error of the groundwater levels is approximately 7. The arithmetic mean error is 1.
Figure 6. Comparison of observed and simulated water heads at monitoring wells in the site model. The velocity field and the groundwater level in the second scenario with the pumping well are shown in Figure 7.
To gain water budget between the two creeks and the pumping well, a sub-model was introduced to reveal the groundwater flow in more details. Moreover, the sub-model function can display the process of stream-flow depletion for both large areas and small-scale local regions.
Figure 7. Groundwater flows simulated by the main model left and the sub-model right. Figure 8 shows the process of water balance into and out from the aquifer in the natural conditions, namely without pumping.
Positive flow above the lateral axis in Figure 8 indicates that creeks and rivers get a water supply from groundwater, while the negative flow below the lateral axis implies creeks and rivers lost water into the aquifers. Infiltration recharge is distributed by the lost water from Twin Creek, Chippewa Creek, Muskegon River and other rivers.
The recharge into the aquifer is in total 3. For Twin Creek and Muskegon River, both of them only gain water from the aquifer. The supplying rate from groundwater is 2. For Chippewa Creek, parts of its reaches gain water from the aquifer and the gaining flux rate is 9. By using the water balance module, some of the other rivers will gain groundwater of 1. In summary, the flux rate of their gaining groundwater is 1.
The error of water budget in the aquifer is 0. It is obvious that the error is quite small by applying the water balance function in this simulation. Therefore, the water balance module in the 3D IGW model is capable of dealing with the interaction between groundwater and river systems. Figure 8. Water balance in the Osceola watershed without pumping condition. Figure 9 illustrates the distributions of precipitation recharging through infiltration in the study watershed.
Owing to the pumping effect of a proposed pumping rate of Therefore, stream-flow will be affected by the withdrawal of the pumping well. The comparison of water fluxes with and without pumping well is given in Table 3. Table 3 Flux comparison under the conditions with and without the pumping well.

Simulating moving boundary using a linked groundwater and surface water flow model. View Metrics. But I didn't find anything preventing it from being used. Could you run remove and then add command again and share the output please? Could you share more information about the error? Then I execute "powershell -noprofile -executionpolicy bypass -file. But I get nothing added I've restarted explorer So strange!
Here are the log file. Looks like all register entries added, but no Drive FS in sidebar. It does add the correct registery keys as I manually verified each one by looking them up in regedit. The two menu items show up. However unfortunately clicking the sidebar menu for the Team Drive does nothing whereas clicking the sidebar menu for the personal drive correctly opens the appropriate folder.
This is really strange as I have been comparing the code you execute for both the personal and team drive and it is exactly the same apart from the variables of course. It actually boggles my mind why this does not work properly as all the properties for the different attributes are exactly the same for both personal and team registery keys, as per your script.
Btw, Google decided to rename their folders again :. The casing for zh-CN might be lower case for 'drives'. This time I could not find the exact translation. Unfortunately I didn't find any solution. I guess there's difference between the implementation of personal drive and shared drive in the filesystem, which may lead to different "Attributes" flags.
But I have no idea which flag need to tweaked. Skip to content.
