Probabilistic Calculation of Design Floods?SPEED
The probabilistic calculation of design floods was initiated in the 60s to overcome statistical calculation uncertainties. SPEED takes up and expands this original concept in the form...
Stormwater Infiltration Design Based on Rainfall Statistics and Soil Hydraulics
When comparing stormwater infiltration with other methods for stormwater drainage an appropriate design procedure is necessary. The method proposed for future Danish guidelines is based...
Design and Analysis of an Irrigation Pond Using Urban Stormwater Runoff
Stormwater held in detention ponds can be reused for irrigation. A simulation of a mass balance on pond storage volume using rainfall and evaporation data for selected areas is presented...
Retrofitting a Detention Facility for Improved Quantity Control
Historically, detention facilities in the U.S. were first designed, constructed and operated for the single purpose of flood control. This led to a second phase, in which recreation and...
A Semi Passive Nutrient Injection System for In Situ Bioremediation
A permeable cutoff wall is installed across the path of a contaminant plume. The water in the wall can be amended with the desired nutrient solution using pumping and injecting wells within...
A Review of Surface-Groundwater Interaction Models
Surface-water and groundwater systems are in continuous dynamic interaction. Processes such as infiltration from surface waters and precipitation, the discharge of groundwater to surface...
Model Structure Validation in Groundwater Modeling
Structure equivalence models (SEM), a new concept in groundwater modeling, have been developed to assist in groundwater planning and management. Using SEM, the engineer is able to satisfy...
The Computer-Assisted Design of Multi-Ponds in Series for Stormwater Management
When a site's topography prohibits the installation of a single stormwater management pond, the drainage system can be integrated with multi-ponds in series. A computer program written...
Sacramento Drainage Manual?Hydrologic Procedures
For a period of over two years, HDR Engineering, Inc. (HDR) and HYDMET have been working with the City and County of Sacramento to develop a Drainage Manual. This Manual contains seven...
Sacramento Hydrologic Procedures Interim Adoption
In November 1989, the County and City of Sacramento jointly undertook the development of a manual for the design of drainage and flood control facilities in the region. Significant technical...
Linear Pertubation Model: An Application to Tanzanian Catchments
Floods are still a problem to many countries in the world todate. Floods do cause damage to property and sometimes loss to human life. Flood control measures by structural and non-structural...
A Frost Protection Design for Fruit Trees in Southwest Colorado
The project explores the feasibility of producing commercial quantities of fruit in the high and arid environment of Southwestern Colorado by using low-volume water delivery systems for...
Computerized Irrigation Project Earthwork Design
A procedure was developed to perform earthwork optimization and land-leveling design for irrigation projects using aerial photogrammetry, a microcomputer and civil engineering computer...
Overland Flow Resistance Estimation from Small-Plot Data
The correct application of physical process models, such as the kinetic wave approximation to shallow overland flow, is dependent upon selection of appropriate values for parameters which...
Design and Management of Evaporation Ponds
The evaporation ponds in use in the San Joaquin Valley were designed and constructed to dispose of agricultural drainage water in a region of low soil permeability and high water table....
IRRICAD ? Computerized Irrigation Design
IRRICAD is a software program that helps irrigation designers by using a computerized systems approach to design. The program features drawing CAD input, interpolation of elevation data,...
FLUME 3.0: A Computer Program for Designing Flumes and Weirs
Long-throated flumes and broad-crested weirs are becoming the preferred measuring devices for use in irrigation canals. A computer program for calibrating these flumes and weirs has been...
BASIN 2.0 for the Design of Level-Basin Irrigation Systems
The purpose of this paper is to present a computer program for the hydraulic design of level-basin irrigation systems. The first of three design modes provides design based on the advance...
CPIVOT v 2.0 Center Pivot Analysis and Design Software
A micro-computer based software package is presented which can be used for hydraulic design and/or analysis of center pivot irrigation systems. The software is written in C and requires...
Flow Simulation for Surface Irrigation Design
Experience shows that even the most sophisticated and accurate computer models of the surface-irrigation process will not be widely used by design agencies unless they manifest a certain...
