OFFICE OF SURFACE WATER TECHNICAL MEMORANDUM NO. 95.08

Subject:  Release of Water-Resources Investigations Report 94-4168,
          "Users Manual for an Expert System (HSPEXP) for Calibration
          of the Hydrological Simulation Program - Fortran"

The purpose of this memorandum is to announce the availabilty of the 
subject report and to distribute documentation to Districts and other 
selected offices. The program HSPEXP is provided to substantially 
shorten project time for the hydrologic calibration of the 
Hydrological Simulation Program - Fortran (HSPF). We recommend the 
report be brought to the attention of technical and management 
personnel concerned with watershed and river basin modeling studies.

HSPF is currently being used in District investigations (1) to 
provide cooperators a calibrated tool to evaluate the impact of 
proposed land use changes and water control structures on urban 
flooding, (2) to determine the contributions through time of nutrient 
loads from urban lands, agricultural lands, atmospheric deposition, 
and wastewater treatment plants and to assess management scenarios 
for the reduction of the nutrients, (3) to identify and evaluate 
possible options to reduce high water levels in a recreational lake 
in a rural setting, (4) to evaluate management scenarios for managing 
urban point and nonpoint sources, and (5) to evaluate impacts of 
water allocations and operations on frequencies of water shortages 
and water quality conditions critical to an endangered specie. 

HSPEXP is the product from a productivity enhancement project 
involving the Water Resources and Geologic Divisions. The program 
interactively provides the user quick access to tabular summary 
statistics of results, 11 types of graphic summaries, expert advice 
on parameter changes for calibration, input parameters for 
modification, and simulation of the HSPF model.

The Hydrologic Analysis Support Section (HASS) is providing the 
distribution of HSPEXP. To obtain the program for use on the Data 
General, connect to hassrvares.er.usgs.gov/ by anonymous ftp, change 
to directory pub/SW, and retrieve files hspexp.tar.Z and 
readme.hspexp.  

The readme file contains instructions for installing the program. If 
there are problems installing the program, contact HASS by electronic 
mail, wrdapp@usgs.gov, or call Kate Flynn, (703/648-5313). For 
technical assistance contact Alan Lumb (703/648-5306) or Kate Flynn.  
To obtain a copy of HSPEXP for a PC running MS DOS, or a copy of the 
HSPF USers Manual, send electronic mail to wrdapp.
