Selection of Sediment Transport Relations: Part I, Review of Sediment Transport Comparisons
There are a great number of sediment transport relations in existence in the world today. The engineer is often faced with the problem of choosing the most appropriate relation for the...

Construction of Performance Contours on the Storage-Yield Plane of a Within-Year Reservoir System
The reservoir storage-reliability-yield (S-R-Y) relationships developed in the past have considered only the probability of failure to meet the target requirements, but not the likely...

Protection against Flooding: A New Delta Plan in the Netherlands
The Netherlands are situated on the delta of three of Europe's main rivers: the Rhine, the Meuse, and the Scheldt. As a result, the country has been able to develop into an important industrial...

Controlling the Impacts of Development on Storm Water Quality through Proper Site Planning and Design
Land development and construction activities can significantly alter drainage patterns, increase runoff peak flow and volume, and contribute pollutants to storm water runoff. Federal and...

Analysis of Long-term Supply-demand Planning of Water Resources in Taiwan
