Assigning Spatially Variable PM Properties using “Map property from raster for chosen elements”
If you have ever tried to assign spatially variable material properties in your HGS models using raster files, you will already know that there were several different command specific to individual properties.
Boundary Condition: Reservoir with Spillway
The February 2022 release of HydroGeoSphere (Revision 2356) introduced an advanced boundary condition: the reservoir with spillway. This new feature builds upon the basic reservoir boundary condition, offering enhanced control over water release in your models. With parameters for surcharge reservoir storage, spillway discharge rates, and gate discharge, this boundary condition simulates complex hydraulic operations with greater precision. Unlike the basic reservoir BC, which relies solely on time-value tables, the reservoir with spillway incorporates inflow hydrographs, spillway discharge, and overflow discharge mechanisms, making it an invaluable tool for realistic water management scenarios.
Simple Drain and Makeup Water Boundary Conditions
This post describes how to use two boundary conditions that maintain a target head in the event that head would exceed (simple drain) or undershoot (makeup water) a specified value. Conceptually we can think of these boundary conditions as one-way boundary conditions where water can only enter (makeup water) or exit (simple drain) the system and are active only when the target value is reached. We find these two boundary conditions very useful when trying to represent water management scenarios.
