  1. Link Boundary Condition

    Hello, Has anyone run into issues using the "link" boundary condition type, specifically with the SRH-2D preprocessor stalling when a link boundary condition type is used? Thanks!
  2. Hey all! I have a question regarding boundary condition set up. I am working on a regional model of an large aquifer field which is used for drinking water purposes. Hydrologic and hydrogeologic conditions are at this stage of the research verry clear. We are dealing with open aquifer field where boundary condition is representing inflow to the aquifer from surrounding sedimentary formations. We have calculated the infow using National groundwater recharge model and at this stage we have data of infow (Q [m^3/s]) for every cell of the boundary condition. Is it possible to calculate the needed hydraulic head in order to simulate the boundary conditions as constant head?
  3. SRH-2D Error

    We are using SRH-2D to model a proposed channel cut in a river. The inlet boundary condition we're using is a variable flow rate with positive and negative values as we have a tidal flow condition. When I run the model, I receive the error shown below. It seems like the negative flow rates are the source of the error. Does anyone know how to allow for negative flow rates in SRH-2D?
  4. Gaps in boundary conditions with MODFLOW-USG

    Has anyone experienced gaps in boundary conditions (not all cells along a boundary arc are being assigned the boundary condition) with MODFLOW-USG or after converting a structured grid to an unstructured grid? What could be causing this problem? Greg
  5. Node strings

    hello there, of recent i've encountered a typical problem. i've built a mesh for a domain and done a lot of manual editing on it. unknowingly i've lost the land boundary node string, i've tried changing colors, but of no use. ocean nodestring is visible in blue. so 'm sure land node string is gone. is there any automated way to get it back (please don't suggest i've to manually do it). Thanks in advance, great day. --karunakar kintada Scientist
