Download Documentation on Detention Pond Design (PDF File)
File Size: 1318314 bytes
File Date: Wed May 15 14:36:15 2002
The traditional design of storm drainage systems has been to collect and convey storm runoff as rapidly as possible to a suitable location where it can be discharged. As areas urbanize this type of design may result in major drainage and flooding problems downstream. Under favorable conditions, the temporary storage of some of the storm runoff can decrease downstream flows and often the cost of the downstream conveyance system. Detention storage facilities can range from small facilities contained in parking lots or other on-site facilities to large lakes and reservoirs. This PDF file provides a general design criteria for detention/retention storage basins as well as procedures for performing preliminary and final sizing and reservoir routing calculations.

File Date: Thu Mar 8 15:28:34 2001
This design manual provides a comprehensive and practical guide for the design of storm drainage systems associated with transportation facilities. Design guidance is provided for the design of storm drainage systems which collect, convey, and discharge stormwater flowing within and along the highway right-or-way. Methods and procedures are given for the hydraulic design of storm drainage systems. Design methods are presented for evaluating rainfall and runoff magnitude, pavement drainage, gutter flow, inlet design, median and roadside ditch flow, structure design, and storm drain piping. Procedures for the design of retention facilities and stormwater pump stations are also presented, along with a review of urban water quality practices. A summary of related public domain computer programs is also provided.

This document provides comprehensive culvert design material. Culvert design methods are presented for both conventional culverts and culverts with inlet improvements. Storage routing techniques are included which permit the designer to account for ponding effects upstream of the culvert. Unique culvert applications, erosion and sediment control, debris control, structural aspects, and long span culverts are discussed. Inlet control, outlet control, and critical depth design charts, are included for a variety of culvert sizes, and shapes, and materials. Dimensionless culvert design charts are also provided for the design of culverts.

The Technical Release 55 (TR-55) User Manual presents simplified procedures for estimating runoff and peak discharge in small watersheds. In selecting the appropriate procedure, consider the scope and complexity of the problem, the available data, and the acceptable level of error. While this user manual gives special emphasis to urban and urbanizing watersheds, the procedures apply to any small watershed in which certain limitations are met.
