Hydraulic calculations and stability calculations for fixed weirs in accordance with the "Headworks" of land improvement and the "Design Guidelines for Floor Stop Structures" in national land development are possible.
Land improvement "pipeline" and "water supply facility design guidelines" compliant, land improvement "headworks" follow the national development "floor stop structure design manual," performing hydraulic calculations and stability calculations for fixed weirs. The formats accommodate "vertical wall type" and "sloped type." The calculations include assessments for "submerged overflow" and others, as well as evaluations of the water hammer length considering the pump pressure, and the examination of the protective floor lengths for sections A and B. In the stability calculations, up to six cases can be considered for changes in water depth during normal and seismic conditions. The calculation results can be reviewed on a preview screen, and Word output is also possible.

basic information
- The design target structure can be selected as either a vertical wall type or an inclined type. - The calculation formula for the water hammer length can be specified as either the Brai method or the Rand method. The calculated water hammer length can be adjusted by manually inputting the confirmed water hammer length. - Depending on the hydraulic conditions, it can be determined whether there is complete overflow or submerged overflow. - Shape dimensions can be input while checking the image diagram based on the selected format. - The examination of piping (the embedment length of the waterworks) can be calculated using the Rain method, the Brai method, or both (for comparative analysis), taking into account the length of the infiltration path to calculate the required length. - The thickness of the water hammer length is assessed to ensure it meets the required thickness for each cross-sectional change. - For the A-section flooring work, it is possible to calculate the required length by specifying the arrangement of the step-up and end sill (χ0). Additionally, the height (W) can also be calculated. - Design cases can be combined for normal/earthquake conditions, the presence or absence of uplift pressure, and upstream/downstream water depths. - The calculation of the block weight for the flooring work lengths in the upstream and downstream "A section and B section" is possible. - The stability calculation results can be displayed collectively on a single screen for each load case regarding overturning, sliding, and ground support capacity, and the details of the calculations can also be verified. - The calculation report can be previewed for content confirmation, and then printed or converted to Word format.
