HEC-HMS

The Hydrologic Modeling System (HEC-HMS) is designed to simulate the precipitation-runoff processes of dendritic drainage basins. It is designed to be applicable in a wide range of geographic areas for solving the widest possible range of problems. This includes large river basin water supply and flood hydrology, and small urban or natural watershed runoff. Hydrographs produced by the program are used directly or in conjunction with other software for studies of water availability, urban drainage, flow forecasting, future urbanization impact, reservoir spillway design, flood damage reduction, floodplain regulation, and systems operation.

The program is a generalized modeling system capable of representing many different watersheds. A model of the watershed is constructed by separating the water cycle into manageable pieces and constructing boundaries around the watershed of interest. Any mass or energy flux in the cycle can then be represented with a mathematical model. In most cases, several model choices are available for representing each flux. Each mathematical model included in the program is suitable in different environments and under different conditions. Making the correct choice requires knowledge of the watershed, the goals of the hydrologic study, and engineering judgement.

HMS M30

HMS M30 was a Royal Navy M29-class monitor of the First World War.

The availability of ten 6 inch Mk XII guns from the Queen Elizabeth-class battleships in 1915 prompted the Admiralty to order five scaled down versions of the M15-class monitors, which had been designed to utilise 9.2 inch guns. HMS M30 and her sisters were ordered from Harland & Wolff, Belfast in March 1915. Launched on 23 June 1915, she was completed in July 1915.

Upon completion, HMS M30 was sent to the Mediterranean. Whilst enforcing the Allied blockade in the Gulf of Smyrna, HMS M30 came under fire from the Austro-Hungarian howitzer battery 36 supporting the Turkish, and was sunk on 14 May 1916.

HEC-1

HEC-1 is software that was developed by the US Army Corps of Engineers to estimate river flows as a result of rainfall. It was written in the FORTRAN language and until 1984 could only be run on a mainframe computer. When desktop computers became popular the program was ported to the PC.Engineers and scientists still use it today because of its ability to model a wide range of natural hydrologic systems.
