Developed by the Hydrologic Engineering Center, HEC-1 is the most commonly-used lumped parameter model available. HEC-1 is designed to simulate surface runoff from a single precipitation event.


HEC-HMS is the next generation hydrologic model developed by the Hydrologic Engineering Center. Its intent is to replace HEC-1, and it features many of the same modeling capabilities as HEC-1 and additional capabilities such as the MODClark quasi-distributed (2D) hydrologic model. WMS has a fully-featured interface to the MODClark hydrologic model and includes documentation and step-by-step tutorials showing how to setup MODClark and other types of HMS models.


NSS contains all of the NFF functionality and equations as well as low flow and other probability equations.


Developed by the NRCS, TR-20 is designed to compute surface runoff from natural or synthetic rainstorm events.


TR-55 was developed by the NRCS as a simplified method to compute storm runoff in small, urbanized watersheds.


MODRAT is the specialized Modified Rational Method program used by the County of Los Angeles, California to compute surface runoff.

Rational Method

One of the simplest and best-known methods of hydrology, the Rational Method computes peak discharge from an area based on rainfall intensity and a runoff coefficient.


The Hydrological Simulation Program - FORTRAN simulates hydrologic and water-quality processes on land surfaces, streams, and impoundments. It is Often used in the development of TMDLs.


The EPA Storm Water Management Model (SWMM) is a dynamic rainfall-runoff simulation model used for single event or long-term (continuous) simulation of runoff quantity and quality from primarily urban areas.


xpswmm, developed by XP Software, is a comprehensive software package for modeling stormwater, sanitary and river systems. xpswmm is used by scientists, engineers and managers to develop link-node (1D) and spatially distributed hydraulic models (2D). It simulates natural rainfall-runoff processes and the performance of engineered systems that manage our water resources.


HEC-RAS is a 1D hydraulic model for computing water surface profiles for steady state or gradually varied flow.


The Simplified Dam-Break (SMPDBK) was developed by the National Weather Service (NWS) for predicting downstream flooding produced by a dam failure.


Developed by USACE ERDC, GSSHA is a distributed (2D) hydrologic model developed for analysis of surface runoff, channel hydraulics, and groundwater interaction. Water quality and sediment transport are also supported.


CE QUAL W2 is a 2D (profile) hydraulic model used for water quality analysis in rivers and reservoirs where vertical variation analysis is required.
