The development of novel interactive visualizations can substantially contribute to environmental modeling and understanding of complex environmental processes. To allow the Web Map Service (WMS) to support this, this paper explores a generic framework in which a dynamic environmental modeling process can be interactively visualized, controlled and tuned on the Internet by using Java 3D-based h...

Information-gap (info-gap) modeling is put forth as a basic approach for enhancing decision making under uncertainty, especially when there is a high level of uncertainty and little information is available. The great need for having realistic techniques for describing severe uncertainty can be illustrated in water resources management by pointing out the wide range of uncertainties present in ...

Dynamic spatial modeling addresses computational aspects of space-time process modeling. The types of processes it is meant to deal with are commonly found in Earth and biological sciences, such as hydrology and ecology. Geographical information systems (GIS) are a popular tool for modeling these application areas. A GIS provides spatial data structures, query capability and functions to manipu...

A distributed model for simulating the land surface hydrological processes in the Heihe river basin was developed and validated on the basis of considering the physical mechanism of hydrological cycle and the artificial system of water utilization in the basin. Modeling approach of every component process was introduced from 2 aspects, i.e., water cycle and energy cycle. The hydrological proces...

An urban watershed in Xiamen was selected to perform the parameter uncertainty analysis for urban stormwater runoff modeling in terms of identification and sensitivity analysis based on storm water management model (SWMM) using Monte-Carlo sampling and regionalized sensitivity analysis (RSA) algorithm. Results show that Dstore-Imperv, Dstore-Perv and Curve Number (CN) are the identifiable param...

Hydrological models are a popular tool for simulating catchment processes in response to a rainfall event. The wide range of available models means that hydrologists are faced with the problem of determining which model is best applied to a catchment in any modeling exercise. An attractive alternative to selecting a single hydrological model is to combine the results from several models, thereb...
