RHESSys Simulation for HPC use with new CyberGIS-Compute Service

Introduction

RHESSys (Regional Hydro-Ecological Simulation System) is a GIS-based, terrestrial ecohydrologic modeling framework designed to simulate carbon, water and nutrient fluxes at the watershed scale. RHESSys models the temporal and spatial variability of ecosystem processes and interactions at a daily time step over multiple years by combining a set of physically based process models and a methodology for partitioning and parameterizing the landscape. Detailed model algorithms are available in Tague and Band (2004).

This notebook demonstrates parallel job submissions of RHESSys ensemble simulations from CyberGIS-Jupyer for water to HPC (XSEDE), visualizes RHESSys output, and evaluate RHESSys efficiency with simulation runoff and observation streamflow.

Watershed: Coweeta subwatershed 18, NC, USA

The Coweeta Long Term Ecological Research (LTER) Program is based on a collaborative agreement between the University of Georgia Research Foundation in Athens, Georgia, and the USDA Forest Service Coweeta Hydrologic Laboratory in Macon County, North Carolina. This study area is Coweeta subbasin 18 where is the one of the subbasin in Coweeta watershed. (Coweeta: 16 km2, subbasin18: 0.124km2)
