2 Contents Development In CUAHSI Outside CUAHSI Improvement Conclusions

3 1. Web Service Development
Paper copy, Disk storage, , FTP, Web page Web services XML, SOAP, WSDL, UDDI Desktop software Integrated Data Viewer HydroDesktop Currently, Paper copy is still a part of data source in China, and typing data from paper copy into computer is an important job for hydrology students. FTP (File Transfer Protocol) XML is used to tag the data, SOAP is used to transfer the data, WSDL is used for describing the services available and UDDI is used for listing what services are available.

16 4. Suggestions for Improvement
Minor changes Base Model Some minor changes will be suggested in the report. One thing I like to talk here and the only thing I want you to remember is a concept of base model.

17 Base Model (Base Map, Structure & Data)
USGS EROS Data Center Arc Hydro Base Model (Base Map, Structure & Data) Setting up HydroModeler → HydroDesktop download data automatically. USGS Streamflow data USDA Soils Data National Land Cover Institute National Climate Data Center Nexrad stage III precipitation data (Figures from AGWA model)

18 Base Model Base Model Offers everyone a model.
Model structure and data needed. Base Model Offers everyone a model. Saves users’ time for their research interests. Standard. USGS EROS Data Center National Land Cover Institute Download to Database HydroDesktop Delineate & Link maps together DEM Base Model Land use If not all the data needed, at least it can link to and download the common used data. Hopefully, in the near future, when people comparing models or results, they have to refer to HydroDesktop base model. … Soil USDA Soil data Precipitation National Climate Data Center Nexrad stage III precipitation data

19 5. Conclusions Integrates the products in CUAHSI project
Has more features than some other likewise products Base model for everyone Future work More suggestions Report Especially, I expect to hear some good suggestions from you.
