OFFICE OF SURFACE WATER TECHNICAL MEMORANDUM NO. 97.03

Subject:  Distribution of Water-Resources Investigations Report 97-4050,
          Enhancements to the Branched Lagrangian Transport Modeling
          System, by Harvey E. Jobson

The Branched Lagrangian Transport Model (BLTM) is widely used throughout WRD 
as an unsteady water-quality model, and it has undergone a number of 
modifications and improvements since it was first documented in 1987. The 
attached report documents these modifications and, especially, addresses the 
addition of reaction kinetics which mimic those in the popular steady state 
model, QUAL2E.

The purpose of this memorandum is to announce and to distribute a number of 
copies of the subject report.
