Item Decision support for active water management(2013-05) Wood, Alison Powell; Maidment, David R.Active water management uses real-time information to continually respond and adjust to water management needs and situations. To support active water management, the Texas Commission on Environmental Quality (TCEQ) needs tools to access and understand data and to apply that understanding to operational decisions. The work described herein addresses two objectives in providing decision-support for the TCEQ: (1) methods for including environmental pulse flow regulations in water rights documents, and (2) improved ease of access to information needed for TCEQ watermaster operations, particularly in times of drought. A Pulse Scaling Method for calculating the trigger flow rate, volume, and duration of flow pulses, using known characteristics at a reference location A, that are appropriate at a target location B (with unknown characteristics) was developed from three key relationships found in the written environmental flow regulations for fifteen locations in the Trinity, San Jacinto, Sabine, and Neches basins. Applying the method and analyzing the results shows that the predictions are statistically consistent with original regulations. A Common Operating Picture is a layered web-map allowing simultaneous access to one or more spatially-related datasets that TCEQ watermaster staff need to consider in decision-making. By its very nature as a dynamic map with associated time series, the Common Operating Picture presents data as information in a way that can support water resource management and decision-making. The project is currently in the pilot stage, with a number of data sources included and an interface available, but with additional work planned and further testing needed before larger-scale implementation.Item Session 2D | Introduction to ArcGIS Online(2022-05-24) Shensky, Michael; Jones, Sylvia; Carter, KateThis 90-minute session will provide a brief introduction to geographic information systems (GIS) and ArcGIS Online. It will show how ArcGIS Online can be used to manage, visualize, and share geospatial data. Participants will learn how to search ArcGIS Online for data, upload local datasets, customize dataset symbology, and carry out basic analysis. They will also learn how to create content in ArcGIS Online by publishing a hosted feature layer and by saving and sharing a web map. The workshop structure will consist of presentation slides and a hands-on interactive portion where participants will gain direct experience working with ArcGIS Online. This session is intended for all TCDL attendees who are interested in GIS and no prior experience is required. It is preferred that attendees have a pre-existing institutional ArcGIS Online account created prior to the start of the workshop, but this is not a requirement and attendees will have the option to create a public ArcGIS Online account during the session. Participants will be given time to ask questions at the end of the workshop.
