Hydraulic calculations and stability calculations for fixed weirs in accordance with "headworks" for land improvement and "floor stop structure design guidelines" for national land development are possible.
Land improvement "pipeline" and "water supply facility design guidelines" are adhered to, and land improvement "headworks" follow the national development "floor stop structure design manual," conducting hydraulic calculations and stability calculations for fixed weirs. The formats correspond to "vertical wall type" and "sloped type." The calculations include judgments such as "submerged overflow," and it is possible to consider the calculations of the water control structure length and the determination of the water hammer length considering the lifting pressure, as well as the examination of the protective floor structure lengths for sections A and B. In stability calculations, up to six cases can be examined 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 Braithwaite formula or the Rand formula. The calculated water hammer length can be reflected in the calculations by manually entering the confirmed water hammer length. - Depending on the hydraulic conditions, it can be determined whether there is a complete overflow condition or a submerged overflow. - Shape dimensions can be input while checking the image diagram based on the selected type. - The consideration of piping (the embedment length of the drainage structure) can be calculated using the Rain formula, the Braithwaite formula, 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 determine whether it meets the required thickness for each cross-sectional change. - For the A section of the protective floor 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 conditions/earthquake conditions, presence or absence of uplift pressure, and upstream/downstream water depth. - The weight calculation for the protective floor work length blocks for the upstream and downstream "A section and B section" is possible. - The stability calculation results can be displayed collectively on the screen for each load case regarding overturning, sliding, and ground bearing capacity, and the details of the calculations can also be reviewed. - The calculation report can be printed or converted to Word after confirming the content on the preview screen.
