Build Status
Brief Introduction
The Spatially Explicit Integrated Modeling System (SEIMS), is a lightweight, modular, and parallelized watershed modeling framework, that focusing on build and perform watershed process models in a plug-and-play way, and conduct scenario optimization of watershed best management practices (BMPs).
SEIMS is implemented using standard C++ and Python to be cross-platform compatible. SEIMS uses CMake to manage the entire project for compatibility on mainstream compilation environments. The compiled C++ programs include the SEIMS main programs (the OpenMP version and the MPI&OpenMP version), SEIMS module library (i.e., dynamic/shared libraries), and executable programs for data preprocessing. Python is used for utility tools including data preprocessing, calibration, sensitivity analysis, scenario analysis, and so on.
SEIMS contains several module categories, include Hydrology, Erosion, Nutrient, Plant Growth, BMP Management, etc. Algorithms are integrated from SWAT, LISEM, WetSpa Extension, DHSVM, CASC2D, etc.
SEIMS is still being developing and any constructive feedback (issues or push requests) will be welcome and appreciated.
Installation
Users are highly recommended to take a look at the automatic workflow of installation and testing of SEIMS on Windows, Linux, and macOS through GitHub actions. The configuration yml scripts are located in SEIMS/.github/workflows. The detailed instruction for installing SEIMS can be found here.
