15- Visual MODFLOW creates detailed contour maps of modeling results including: (a) Heads, drawdown and multispecies concentrations (b) Water table elevations and net recharge all of the above (c) Head difference between layers and flux between layers 16- The groundwater model is an abstraction or an approximation of the real system depends on...... (a) The mathematical equation (b) The groundwater flow direction (c) The purpose of the model. (d) The porosity and permeability 17- The model design phase really needs to be balanced because......... (a) The model grid really is the largest scale, at which the model solution will be not computed, (b) The model grid really is the largest scale, at which the model solution will be computed, (c) The model grid really is the smallest scale, at which the model solution will be not computed, (d) The model grid really is the smallest scale, at which the model solution will be computed. 18- In specified head boundaries, the head remains constant, which means that... (a) Water is simulated as moving in the groundwater at a rate sufficient to maintain the specified head (b) Water is simulated as moving out of the groundwater at a rate sufficient to maintain the specified head. (c) Water is simulated as moving in or out of the groundwater at a rate sufficient to maintain the specified head. (d) Water is simulated as stagnant the groundwater at a rate sufficient to maintain the specified head. 19-Once the model has been calibrated, it must be verified, this is done by using..... (a) Historical data not used for calibration and running the model through that time period to make sure the model can represent data that was used during calibration. (b) Historical data used for calibration and running the model through that time period to make sure the model can represent data that wasn't used during calibration. (c) Historical data used for calibration and running the model through that time period to make sure the model can represent data that was used during calibration. (d) Historical data not used for calibration and running the model through that time period to make sure the model can represent data that wasn't used during calibration. 20- The groundwater encounters these underlying issues (a) Waterlogging (b) Groundwater mining (c) Groundwater Pollution (d) All of the above
