Estimating Runoff and Peak Discharge (EFH2)
(4.87MB): windows NT version : CCE approved
This program provides simplified procedures for estimating surface runoff and peak discharge from small rural watersheds for use in designing soil and water conservation measures. Computation procedures are described in the Engineering Field Handbook, Chapter 2 (EFH2).
TR-55 Urban Hydrology for Small Watersheds
(264 KB): version: 2.00 Date: 01/15/90 Prompts for data input
This program provides simplified procedures to calculate storm runoff volume, peak rates of discharge, and storage volumes required for storm water detention basins. These procedures are applicable in small watersheds, especially urbanizing watersheds. The program provides for hydrologic analysis of a watershed under various combinations of land uses using single-event storm rainfall frequency data. The program can accommodate division of the watershed into 10 subareas and will estimate individual subareas as well as total area peak rates of runoff. This program can also be obtained from the NRCS Water Science and Technology Services web page for Hydrology & Hydraulics / Tools and Models / TR-55. A windows version WinTR-55 is also available.
SITES - Water Resource Site Analysis Software
The SITES software is a descendent of the SCS DAMS2 program. DAMS2 was a full- featured rainfall-runoff routing program developed over an extended time period for use in SCS dam design and analysis. In developing the SITES software, DAMS2 was recorded and the auxiliary (emergency) spillway analysis portion of the program was rewritten and expanded to include new technology for spillway performance evaluation developed through the joint efforts of the Agricultural Research Service and the NRCS.
TR-20 HYDROLOGY - Project Formulation Hydrology (270 KB)
This program can also be obtained from the NRCS Water Science and Technology Services web page for Hydrology & Hydraulics / Tools and Models / TR-20.
