Till instance Surficial units hydraulic conductivity 1.58 5.01 6.31 Hydraulic conductivity for the hydrogeological unit. The median value for hydraulic conductivity is 10^-6.2 m/s, but it ranges from 10^-7.8 to 10^-4.8 m/s. Hydraulic regional conductivity The decreasing trend of transmissivity with depth in the rock is observed in all contexts. The average hydraulic conductivity is 10^-3.9 m/s near the top of bedrock (z = 1 m) which gradually loses an order of magnitude at a depth of 10 m (10^-4.9 m/s), 25 m (10^-5.9 m/s), 60 m (10^-6.9 m/s) and 200 m (10^-7.9 m/s). 0.09 Regional precipitation 2012-04-012013-03-31 regional precipitation (not scope to this area) 2012-04-01 2013-03-31 2013-03-31 2013-03-31 1023.9 1306.5 1064.5 Noire River Valley 2012-04-012013-03-31 Region Recharge 2012-04-01 2013-03-31 2013-03-31 2013-03-31 0 417 114.7 Regional evapotranspiration Yamaska study area 2012-04-012013-03-31 Region Recharge 2012-04-01 2013-03-31 2013-03-31 2013-03-31 370 644.4 575 Regional runoff Yamaska study area 2012-04-012013-03-31 Region Recharge 2012-04-01 2013-03-31 2013-03-31 2013-03-31 79.2 1146.2 460.2 Yamaska Richelieu watershed Watershed General regional fluid body filling Richelieu Yamaska aquifer Vulnerability 2012-04-01 2013-03-31 2013-03-31 2013-03-31 77 187 142 true
