Urban Nonpoint Pollution Control Kettering Demonstration Project
The development of effective nonpoint pollution control programs has become one of the most complex challenges facing local and state authorities. Because of the multifarious nature of...
Evaluation of the Effects of Weather Modification to Enhance Reservoir Yield During Drought?Salinas Valley, California
Cloud seeding has been conducted for water years 1990-91 and 1991-92 in Monterey County, California in response to the extended drought. The Monterey County Water Resources Agency weather...
The Method of Derived Distributions Applied to Peak Flows
Random variables which are functionally related have their probability distributions also related in a prescribed manner. Thus, in theory, the probability distribution of peak discharge...
A Revised Snowstorm Maximization Method for Canadian Boreal Regions
A proposed refinement in the development of design snowpacks for use in the derivation of probable maximum floods (PMF) estimates in the Canadian Boreal is presented. Shortcomings in the...
A Probabilistic Approach to Estimate Design Parameters for Flood Control Projects
The purpose of this paper is to provide engineering consultants with an improved method to estimate design parameters for various return periods in rural areas. The proposed method combines...
Kinematic Mixing in Stratified Aquifers
The mixing process in heterogeneous aquifers is presented as the bending and stretching of material lines. A linear mixing efficiency is defined in terms of the mean values of a unit length...
Unit Hydrograph Estimation Procedures Using Orthogonal Functions
All unit hydrograph estimation procedures based on orthogonal functions are reviewed in this paper. A more physically based orthogonal function (a gamma function) for unit hydrograph estimation...
An Operational GIS to Support State-Wide Hydrologic and Nonpoint Pollution Modeling
A geographic information system(GIS) that is structured for hydrologic and nonpoint pollution modeling(GISHYDRO) became operational in the Maryland State Highway Administration's Division...
A Lake Water Quality Management Model to Evaluate Stormwater Management
A research project was completed to develop a dynamic lake water quality management model for Lake Tarpon, a 10.3 km2, shallow lake in Central Florida....
New Directions in Integrated Hydrologic Modeling with GIS
In 1988, the Florida Institute of Phosphate Research funded a project to develop an integrated hydrologic model to more adequately represent mine reclamation hydrology. Five years later,...
Formulation of a Hydrologic Model, for Use with Remotely Sensed Data
Research is currently being conducted at the Pennsylvania State University, as well as, many other sites, in the area of Geographical Information Systems (GIS) and implementing its application...
An Integrated Software System for 3DFEMWATER: A 3D Grid Generator, A Graphical Post-Processor, and Additional Analysis Tools
An integrated software system for 3DFEMWATER has been developed to improve the groundwater flow modeling process. The system generates finite-element grids, graphically portrays simulation...
Modeling Two-Dimensional Subsurface Flow, Fate and Transport of Microbes and Chemicals
A two-dimensional model to simulate the subsurface flow, microbial growth-degradation, and transport and biodegradation of chemicals in groundwater environments (2DFATMIC) is developed....
A Two-Dimensional Flow and Hydrogeochemical Transport Model
A two-dimensional flow and hydrogeochemical transport model is designed for estimating the movement and attenuation of chemicals after they are released into subsurface systems. This model...
Estimating Exceedance Probabilities of Extreme Floods
Estimates of the exceedance probabilities of extreme floods are needed for risk analysis of dams and nuclear energy facilities. A new approach using a joint probability distribution of...
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...
Adapting BMPs to California Hydrology and Climatology
The State of California has the most diverse hydrology and climatology in the United States. It boasts the highest and lowest elevations in the continental U.S. and annual rainfall varies...
