Integrating Policy Factors in Stream-Aquifer Models
One of the main issues appearing today in the field of water resources is the management of complex hydrologic systems consisting of surface streams and aquifers. The management problem...
Analysis of Alluvial Fan Flooding
Alluvial fans are estimated to cover approximately one third of the land area in the southwestern United States. Because of their relatively gentle slopes and well draining characteristics,...
Storm Dynamics in the Lake Ontario Region
A program package, RAINPAK, was written to develop appropriate rainfall input, based on concepts of the physical processes behind the temporal and spatial distribution of storm rainfall...
Continuous Modelling of Downstream River Erosion Caused by 40 Years of Urbanization
The US EPA Stormwater Management Model (SWMM3) was installed on an IBM-PC compatible network. The adapted program, known as PCSWMM3, and incorporating a simple algorithm for modelling...
A New Dam in California?Piece-of-Cake!
It initially appeared that a series of insurmountable roadblocks would prevent the City of Morro Bay from constructing a new dam and water supply reservoir on San Bernardo Creek near the...
