The river-groundwater interaction is an important component of the hydrological cycle. This study develops an integrated river-GW model that uses a one-dimensional open channel flow model and a three-dimensional saturated GW flow model to describe the dynamic river-GW relationship at the basin scale, as well as groundwater flow and streamflow in arid regions. The model is tested with three cases,...
When visualizing graphs into node-link diagrams, angular resolution is often used as one of the aesthetic criteria measuring the diagram quality in terms of human comprehension. However, angular resolution has not been empirically validated for its relevance to humans. In addition, although many force-directed algorithms have been proposed for automatic graph drawing, performance evaluation of these...
Many automatic graph drawing algorithms implement only one or two aesthetic criteria since most aesthetics conflict with each other. Empirical research has shown that although those algorithms are based on different aesthetics, drawings produced by them have comparable effectiveness. The comparable effectiveness raises a question about necessity of choosing one algorithm against another for drawing...
