Discussion of “<i>Limitations on Seasonal Snowmelt Forecast Accuracy</i>” by Dennis P. Lettenmaier (July, 1984)
Publisher: American Society of Civil Engineers
Bringing Water Data Together
Publisher: American Society of Civil Engineers
Time Patterns of Water Use in Six Texas Cities
Publisher: American Society of Civil Engineers
Abstract: Time series of monthly water use data from 6 Texas cities are examined. The time variation of the data may be divided into long memory (on average, 70% of total variation), short memory (15%) and residual error (15%). ...
Application of GIS Network Routines for Water Flow and Transport
Publisher: American Society of Civil Engineers
Abstract: Network routines are implemented within several geographic information systems (GISs). These routines are primarily used in traffic routing and allocation analyses, and very little work has been done on their application ...
Design of Wastewater Storage Ponds at Land Treatment Sites. II: Equilibrium Storage Performance Functions
Publisher: American Society of Civil Engineers
Abstract: A new reliability‐based method is presented to size a storage pond at a land treatment site operated for the disposal of municipal wastewater. Reliability is defined as the probability that wastewater levels remain below ...
Design of Wastewater Storage Ponds at Land Treatment Sites. I: Parallels With Applied Reservoir Theory
Publisher: American Society of Civil Engineers
Abstract: The problem of designing a wastewater storage pond at a land treatment site is similar in many respects to sizing a water supply reservoir subject to variable inflows and outflows. The similarities and differences of the ...
Modeling Water Demands of Irrigation Projects
Publisher: American Society of Civil Engineers
Abstract: A simulation model for assessing the water demands of large irrigation areas is developed and applied to the mid‐Canterbury region of New Zealand. Observations from historical water use patterns provide a basis for demand ...
Projecting Storage in Highland Lake Reservoir System
Publisher: American Society of Civil Engineers
Abstract: The probability distribution of storage in the Highland Lakes reservoir system on the Lower Colorado River in Central Texas is projected up to six years into the future. Projections are based on simulation using historical ...
Definition and Connection of Hydrologic Elements using Geographic Data
Publisher: American Society of Civil Engineers
Abstract: Constructing a lumped parameter hydrologic model of a watershed involves dividing the watershed into subbasins and determining their connectivity through the stream network. Subbasin boundaries and stream networks can be ...
Coordinate Transformations for Using NEXRAD Data in GIS-Based Hydrologic Modeling
Publisher: American Society of Civil Engineers
Abstract: Gridded precipitation products created as part of the U.S. National Weather Service's Next Generation Weather Radar (NEXRAD) program are referenced to a national grid called the Hydrologic Rainfall Analysis Project (HRAP) ...
