The Changjiang (Yangtze) River Delta: A Review
The Changjiang river delta is the best studied one in China in terms of hydrology, sedimentology and evolution history. The construction of Pudong New Area in Shanghai in the 1990s has...
Stochastic Generation of Daily Low Flows in Estuaries for Salinity Intrusion Studies
Stochastic data generation technique was used to provide a probabilistic approach to a salinity intrusion/low flow study of an estuary in West Malaysia. The Kemaman River on the east coast...
A Sharp-Interface Salt Water Intrusion Code for Layered Aquifer Systems
This paper presents a quasi three dimensional, sharp-interface code that simulates salt water intrusion problems in layered aquifer systems. Efficient and robust numerical schemes make...
GIS Utilization for Analysis of District Drainage Water Recycling
An ARC-INFO GIS system was used to identify physical drainage facilities in a 32,000 ha area of the San Joaquin Valley of California. Once the drainage facilities and linkages were established,...
