title: Analysis of Design and Construction Practices in Marsh Creation Projects

description: This study analyzed the relationship between different factors affecting the efficiency of marsh creation projects. Through a historical analysis of completed marsh creation projects in different basins around Louisiana, it was demonstrated that there is a direct relationship between the percentage of fines in the dredge material and the volume of marsh that can be created with it. A recently completed marsh creation cell, Increment 1 of the Caminada Headlands Back Barrier Marsh Creation Project (BA-171), was also studied to better comprehend the dredge material’s behavior after placement. A combination of Cone Penetrometer Tests (CPT), vibracores, and Multi-Sensor Core Loggers (MSCL-S) was performed in carefully selected sites across the cell.

description: CMAQ-ready gridded hourly observed lightning flash density data for the 12US1 domain from the World Wide Lightning Location Network (WWLLN) with scaling (WWLLNs). These daily 24-hour input files contain one 2D variable “LNT” (lightning flash density in flashes/km2/hr, dimensions: (TSTEP, LAY, ROW, COL), with LAY=1) and are used for CMAQ’s lightning NO module to produce inline lightning NO emissions that are distributed vertically by the lightning NO module (https://gmd.copernicus.org/articles/12/3071/2019). To use the inline lightning NO production, the following environmental variables in CMAQ runscript need to be set: setenv CTM_LTNG_NO Y setenv LTNGNO "InLine" setenv USE_NLDN Y (will be changed to USE_FLASH in next CMAQ release) setenv NLDN_STRIKES ${IN_LTpath}/WWLLNs_12km_60min_${YYYYMMDD}.ioapi (The NLDN_STRIKES will be changed to FLASH_FILE in next CMAQ release) setenv LTNGPARMS_FILE ${IN_LTpath}/LTNG_AllParms_12US1.ncf (should be available in the same directory with the WWLLNs data or otherwise be instructed).
