This model was developed specifically for the Louisiana 2012 Coastal Master Plan for barrier shoreline and inlet evolution at a decadal scale.
The Eco‐Hydrology models are capable of simulating long‐term hydrodynamic and water quality processes, where the maximum simulation period was 25 years. They can also cover large spatial domains, e.g. the entire Louisiana coast. The models can simulate complex systems such as the nutrient cycles of nitrogen and phosphorus, which involve multiple chemical processes occurring simultaneously. Outputs include TKN, Nitrate+Nitrite, Ammonium, DON, N-removal, TP, and soluble P.
Predictive models used for the 2012 Coastal Master Plan to predict potential habitats suitable for these species into the future. Multiple reports/models, including crawfish (wild caught), shrimp (brown and white), and oysters.
The Surge/Wave Attenuation Potential Suitability Index (SI) is intended to consider the potential effect of a project in attenuating storm surge/waves that would otherwise impact populated areas. It is based on 500 x 500m model grid cells and calculated on a 5 year time step. The model combines location from areas designated for 100 or 500yr level protection, percent land, vegetation type, and elevation inputs to produce a suitability index for surge/wave attenuation potential ranging from 0.0 to 1.0.
The vegetation model (LAVegMod) described in this appendix is the next generation of a similar model (habitat switching module) initially developed as part of the Louisiana Coastal Area study (Visser et al. 2003). LAVegMod divides the original 5‐habitat model for the Louisiana coast into 19 vegetation types. LAVegMod provides longer estimates of interannual variation in aboveground biomass; however, biomass varies with vegetation type. The model is intended as a tool for protection and restoration planning that provides repeatable estimates of the changes in species composition based on changes in hydrology and wetland area. This tool was developed for use by a trained modeler and is dependent on other models that forecast changes in hydrology and wetland area.
The Wetland Morphology model was developed to predict coastal Louisiana wetland morphologic dynamics in a changing environment (e.g., global warming, eustatic sea‐ level rise [ESLR], land subsidence, freshwater and mineral sediment supply reductions). The model consists of relative elevation and landscape change sub‐models that are developed based upon the best available data and our most recent understanding of the role of coastal biophysical processes including land loss, land gain, marsh collapse, sediment transport, sediment deposition, sediment retention, vertical accretion, organic matter production, sea level rise (SLR), and subsidence on shaping coastal morphology.
CropScape is a geospatial data service which offers advanced tools such as interactive visualization, web-based data dissemination and geospatial queries and automated data delivery to systems such as Google Earth. CropScape was developed in cooperation with the Center for Spatial Information Science and Systems at George Mason University and is hosted their website
The CRSSP Imagery-Derived Requirements (CIDR) Tool enables U.S. Federal civil agencies to enter near-term land remote sensing data requirements. Log in from USGS needed. Data tool is for upload of data acquisition for remote sensing data, related to USGS EarthExplorer Tool.
