Water quality data from estuarine variable hydrologic flow regimes during frequent drought

摘要

The present article provides water quality data collected from three South Texas Estuaries (Guadalupe, Nueces and Lavaca-Colorado Estuaries) during frequent drought from 2011 to 2014. The data described here are presented in the research article “The relationship between suspended solids and nutrients with variable hydrologic flow regimes” Paudel et al., 2019. Quarterly (i.e. four times a year) surface water quality data presented here were collected from various stations lie along river-estuary mouth to oceanic salinity gradient. Followings are the water quality data provided from Texas estuaries at different river flow regimes: pH, DO, TSS, salinity, chlorophyll-a, secchi disc reading, and nutrients (dissolved nitrogen, dissolved phosphorus and dissolved silicate). Surface inflow was obtained by adding gauged, modeled and return flow.
