-Smaller drainage area Would groundwater pumping subtract or add to a groundwater budget? Notice that the CaSe is important in this example. RewriteBase / When equipotential lines are not evenly spaced, (e.g., the gradients are changing in space) there is an underlying reason (as indicated by Darcys law). RewriteCond %{REQUEST_FILENAME} !-f -The salt-rich portion of a rock that might dissolve away), Which of these are causes of salt contamination of groundwater? The present study indicated that the groundwater discharge area was extensive during the dry season, and groundwater discharge into Poyang Lake mostly occurred from the aquifers BF and CPF. which of these features signify a groundwater discharge area In this example the image file must be in public_html/cgi-sys/images/. Water in the soil is used by plants in life functions and leaf transpiration, but it also can evaporate directly to the atmosphere.
