Hi,
I am trying to produce a hyporheic water flow map at my small study site (25-m x 25-m). I have 10 piezometers from which water level data was being collected. Eight were located on the riparian across a meander bend of a stream and two were located in the stream. The first map I attached "april21flowpathmap.jpg" was developed without using the Darcy Flow function. The variables I used to develop flow direction arrows were rasters of land surface elevation (slope) and groundwater level. The second map "w_darcy.pdf" was created using the Darcy Flow function in Spatial Analysis. The Darcy Flow map is showing spiraling around piezometers.
My questions are:
- Do either of these look indicative of shallow groundwater flow?
- What is the reasoning for the spiraling flow?
- Is it possible that the spiraling around the piezometers is trying to show movement downward, as these in-stream piezometers are downwelling?
- Which map would you choose to represent the system?
Thank you kindly for your help!
Leah
