Paper Abstract

The water monitoring network in Northern California provides us with an integrated flow and water-quality dataset of the Sacramento-San Joaquin Delta, the reservoirs, and the two main rivers feeding the Delta, namely the Sacramento and the San Joaquin rivers. Understanding the dynamics and complex interactions among the components of this large water supply system and how they affect the water quality, and ecological conditions for fish and wildlife requires the assimilation of large amounts of data. A multivariate, time series data visualization tool which encompasses various components of the system, in a geographical context, is the most appropriate solution to this challenge. We have developed an abstract representation of the water system, which uses various information visualization techniques, like focus+context techniques, graph representation, 3D glyphs, and colormapping, to visualize time series data of multiple parameters.
