Model Choice and Scale in Urban Drainage Design
This paper addresses the question of model choice and scale by comparing various model applications to a 95-acre gaged catchment, known as the Lake Hills watershed, in Bellevue, Washington....

Kinematic, Diffusion and Dynamic Catchment Modeling
This paper reports on a series of tests aimed at developing improved procedures for catchment routing. The objective is to compare kinematic and diffusion models within several scenarios...

Rainwater Catchment Systems: Advancements in an Appropriate Technology

A Strategy for Caribbean Water Supply Planning

Rainwater Collection and Treatment at a Small Industrial Plant in Puerto Rico

Use of Continuous Simulation Versus the Design Storm Concept for Water Quality
The validity of the design storm concept has been challenged by several investigators since the development of computer simulation models. Of particular interest are the studies that compare...

Stochastic Modeling of Mean Areal Precipitation for Generating Synthetic Streamflows
Statistical precipitation models used as input to conceptual hydrologic models, offer an alternative mechanism for simulating streamflow. In sparsely gauged catchments, or areas where...

Catchment Response Models in the Computer Age
The paper deals with catchment response models and addresses the question - what do we know when we know a model? The history of catchment modelling over the last seventy five years is...

Streamflow Monitoring with Ultrasonic Recorders
In September 1983, four new streamflow monitoring sites were established in a west Chestnut Ridge catchment at the Oak Ridge National Laboratory. Ultrasonic level/flow recorders were used...

A Hydrologic Model Developed for Microcomputers
An event oriented hydrologic catchment model has been programmed for use on a microcomputer. Because the program is written in PASCAL, it uses features of this language that eliminate...

Modelling Percentage Runoff Values for Urban Catchments

Mapping Dispersed Urban Flooding on Alluvial Fans

Urban Hydrology and Catchment Research in the United Kingdom - Progress Since 1979
The Wallingford Procedure for the design and analysis of urban drainage systems was released in late 1981 for use by drainage engineers in the United Kingdom. This was the most significant...

Progress Since 1979 in the Netherlands
Since the last progress-report still more emphasis has been laid on quality aspects of surface waters. Municipalities as well as Provinces and the national government are responsible for...

Hydrology of a South-Central Missouri Cedar Glade

Continuous Models Essential for Detention Design

Run Hydrographs for Prediction of Flood Hydrographs
A bivariate lognormal probability distribution in flood peaks and flood volumes describes families of flood hydrographs, each family with a desired return period. Truncated series of floods...

Airport Catchment Areas and Air Passenger Demand
Air passenger demand modelling is explored for domestic trips between centers of high population in Canada. The research involves a comparison of two methods of zoning. One method considers...

SWMM Model and Level of Discretization
The costs of setting up and running a storm water management model are largely determined by the level of discretization used for a particular catchment. This study investigates the level...
