  1. Dear all, Thanks for taking time to read this email. I am a beginner for GMS, and I am wondering to simulate a scenario of groundwater extraction from a trench, which package should I use? For a local scale, model set up 2km ᵡ 2km, the trench size is 100m long ᵡ 3m wide ᵡ 2m deep, I am using LAKE package to simulate a dewatering process, is it correct? For a large scale, model set up is 50km ᵡ 40km, the trench network will be around 20km long ᵡ 3m wide ᵡ 2m deep, should I use Drain package? And for Drain package, the only attributes are elevation (-2m below ground level), and Conductance (Ca
  2. Hi everyone, Can any of you help me with the following question please? I am a beginner of GMS modelling. I want to set up a transient modflow of trench pump testing, however I don't know how to conceptualize the trench. The trench is 100m long, 2m wide, 1m deep, with 7 observation bores locating around the trench. The water levels of trench and bores were logged for 5 hours with pumping rate 1000L/min, and I need to set up a modflow and calibrate the model. The Drain (DRN) package seems not suitable for conceptualizing the trench as the water level of trenching decreasing with time. So
