Curb-opening inlet capacity depends on the inlet dimensions, longitudinal slope, gutter and roadway cross slope, local depression, and approach flow characteristics. Curb-opening inlets …

Aug 20, 2024 · Technical updates also include updating stormwater quality information with current design practices and performance data, and presenting a new curb opening inlet …

CITY CURB OPENING INLETS OF Carl F. Izzard* SYNOPSIS This paper presents a method of estimating the capacity of a curb opening inlet as a function of the depth of flow in the …

The capacity of an inlet located on a continuous grade is dependent upon a variety of factors including gutter slope, depth and velocity of flow in the gutter, height and length of the curb …

THE capacity of many storm-water inlets can be found by comparing the flow into the inlet with the flow into a wide opening. In this manner, formulas are derived for the design of curb-opening …

Apr 26, 2012 · This study develops a new hydraulic design procedure for curb-opening inlets from experimental data and theory. The results are presented in diagrammatic form for practical use.

The study had three objectives: (1) to determine the hydraulic characteristics of recessed curb inlets for different flow conditions and curb inlet ge ometries; (2) to determine the hydraulic …

Mar 7, 2020 · The hydraulic capacity of combination inlets in sumps depends on the type of flow and the relative lengths of the curb opening and grate. For weir flow, the capacity of a …

This study develops a new hydraulic design procedure for curb-opening inlets based on experimental data. The results are presented in graphical form for practical use.

Nov 1, 2006 · The current design procedure for sizing a single-unit curb opening inlet has been expanded to multiple-unit inlet designs. The decay function derived in this study can …

How does a green infrastructure system capture water in urban areas? Capture Water Through Green Infrastructure Inlets

Types of inlets considered in UDINLET include grate, curb-opening, combination of grate and curb opening, and slot drain. Inlets can be placed on a sump or on a grade.

A curb inlet and two combination inlets (with a grate and curb opening) used for storm-water drainage were tested under varying road conditions, and equations were developed for their …

NEW HYDRAULIC DESIGN CURVES FOR DEPRESSED CURB-OPENING INLETS HAVE BEEN DEVELOPED FROM NEW EXPERIMENTAL DATA. A GENERAL DESCRIPTION OF …

Sep 5, 2002 · This study develops a new hydraulic design procedure for curb-opening inlets from experimental data and theory. The results are presented in diagrammatic form for practical use.

Dec 15, 2009 · In this study, a three-dimensional computational fluid dynamics (CFD) software, FLOW-3D, is used to develop models simulating unsteady, free-surface, shallow flow through …

The goal of this project is to investigate the hydraulic efficiencies of Type 13 (bar inlets), Type 16 (vane inlets), and Type R (curb-opening inlets) for street and roadway drainage.
