The system has 10 circuits, and up to 5 facilities can be added within one circuit! Precise calculations will be performed to determine the adjustment capacity.
This system performs capacity calculations for adjustment ponds using a lateral overflow method, aimed at reducing downstream flow by lowering part of the side walls or embankments adjacent to rivers or waterways, referencing technical standards such as the draft technical standards for sewer rainwater adjustment ponds and disaster prevention adjustment ponds. It allows for integrated calculations of flood control facilities where single, multi-stage, or multiple systems ultimately flow into a single disaster prevention adjustment pond using a rigorous solution method. In the case of multi-stage systems, it is possible to consider direct inflow areas at intermediate stages. 【Features】 - Allows for the setting of multi-stage facilities with the final storage pond as a lateral overflow type storage facility. - Up to 10 systems can be configured, with the ability to add up to 5 facilities within a single system. - Performs calculations of adjustment capacity using rigorous methods. - Outflow from inflow areas can be determined using methods based on rainfall intensity formulas, actual rainfall amounts, or by directly specifying flow rates for each time period. *For more details, please refer to the PDF materials or feel free to contact us.

basic information
【Other Features】 ■ Rainfall intensity types can be selected from Talbot type, Sherman type, Kuno-Ishiguro type, Kimishima type, Nagano Prefecture type, Yamanashi Prefecture type, and Kinki Regional Development Bureau type. ■ Channel cross-sections (river cross-sections) can be input as single cross-sections or multiple cross-sections. ■ Supports adjustment ponds without discharge facilities and adjustment ponds that consider discharge facilities. ■ The water level (flood level) in the adjustment pond at the start of rainfall can be specified. ■ For calculating infiltration volume, options include effective rainfall model, constant deduction model, and retention infiltration model. ■ Calculation of flood spillway and non-overflow section top height is possible. 【Applicable Standards】 ■ Technical Standards for Sewage Rainwater Adjustment Ponds (Draft) Explanation and Calculation Examples, October 1984 (Japan Sewage Works Association) ■ Hydraulic Formula Collection, October 1999 (Japan Society of Civil Engineers) ■ Technical Guidelines for Rainwater Infiltration Facilities (Draft), September 2006 (Rainwater Retention and Infiltration Technology Association) ■ [Supplementary Revision (Partial Correction)] Technical Standards for Disaster Prevention Adjustment Ponds, August 2001 (Japan River Association) and others. *For more details, please refer to the PDF materials or feel free to contact us.
