It emphasizes the effects of agricultural management practices on physical, chemical and biological processes. RZWQM2 is a one-dimensional model with a pseudo 2-dimensional drainage flow. Crop simulation options include the generic plant growth model, DSSAT-CSM 4.0 and HERMES SUCROS models. It also can simulate surface energy balance with components from the SHAW model and water erosion from the GLEAMS model. An automated parameter estimation algorithm (PEST) was added to RZWQM2 for objective model calibration and uncertainty analysis. </p><div><br>Resources in this dataset:</div><br><ul><li><p>Resource Title: RZWQM2 download page.</p> <p>File Name: Web Page, url: <a href=\"https://www.ars.usda.gov/research/software/download/?softwareid=412&modecode=30-12-30-25\">https://www.ars.usda.gov/research/software/download/?softwareid=412&modecode=30-12-30-25</a> </p></li></ul><p></p>", "distribution": [{"@type": "dcat:Distribution", "downloadURL": "https://www.ars.usda.gov/research/software/download/?softwareid=412&modecode=30-12-30-25", "mediaType": "text/html", "title": "https://www.ars.usda.gov/research/software/download/?softwareid=412&modecode=30-12-30-25"}], "identifier": "10113/AA22582", "keyword": ["Root Zone Water Quality Model", "crop production", "climate change", "drainage", "growth models", "energy balance", "water erosion", "GLEAMS model", "algorithms", "uncertainty analysis", "rangelands", "Colorado", "watersheds", "Nematoda", "Georgia", "crops", "soil profiles", "nutrients", "pesticides", "rhizosphere", "irrigation", "tile drainage", "weather", "best management practices", "environmental sustainability", "probability distribution", "temperature", "wind", "relative humidity", "carbon dioxide", "water quality", "environmental impact", "crop rotation", "planting date", "nitrates", "runoff", "pollution load", "groundwater", "pollutants", "rain", "micropores", "macropores", "heat flow", "water table", "evaporation", "transpiration", "soil water", "melting", "climatic factors", "carbon", "mortality", "root growth", "soil pH", "soil solution", "nitrogen", "humus", "crop residues", "ammonium", "mineralization", "nitrification", "denitrification", "volatilization", "adsorption", "organic matter", "bulk density", "surface roughness", "soil density", "fertilizers", "irrigation scheduling", "furrows", "water content", "corn", "wheat", "potatoes", "databases", "statistics", "computer software", "crop models"], "license": "https://creativecommons.org/publicdomain/zero/1.0/", "modified": "2024-02-13", "programCode": ["005:040"], "publisher": {"@type": "org:Organization", "name": "Agricultural Research Service"}, "title": "RZWQM2"}
