This paper presents a method of estimating the capacity of a curb opening inlet as a function of the depth of flow in the approach gutter, the depression of the mlet lip below the flow line of the …

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 …

It is found that the most-efficient types are the combination inlet and the grate inlet. In both cases, the grate should have only longitudinal bars. When the street grade is steep and gutter …

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.

For these types of facilities, the drainage of standing water is accomplished, ideally, by channeling the water along a gutter until it enters a curb opening or "inlet," after which it is car ried away …

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 …

Mar 7, 2020 · the reader wishes to study their background. Inlet capacity, as presented in this chapter, is based on the FHWA Hydraulic Circular No. 22 (HEC-22) methodology (FHWA …

Curb Opening: Depressed Inlet Throat or At-Grade? At largest contributing area modeled, throat can increase inlet capacity 14% and 25% . GI Implications • GI system and pipe utilization may …

From the hydraulic point of view, street inlets are classified into sump and on-grade interceptions. Chapter 6 in this book summarizes the design procedures to size grate, curb opening, slotted, …

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. Inlet interception …

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 …

new hydraulic design curves for depressed curb-opening inlets have been developed from new experimental data. A GENERAL DESCRIPTION OF THE RESEARCH AND OF THE …

Sep 14, 2012 · 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 …

Hydraulic Efficiency of Grate and Curb-Opening Inlets Under Clogging Effect. The goal of this project is to investigate the hydraulic efficiencies of Type 13 (bar inlets), Type 16 (vane inlets), …
