Summary:To provide a rainwater inflow amount prediction device that accurately predicts a rainwater inflow amount.SOLUTION: A rainwater inflow amount prediction device according to one embodiment comprises: calculating main line flow velocity and a main line flow amount at multiple points; calculating a flow time from the multiple points to a pump well 14 from the main line flow velocity at the multiple points and main line extension from the multiple points to the pump well 14; calculating a rainwater inflow amount flowing into the pump well 14 using a water level measured by one of multiple water level gauges and an inflow culvert water gauge installed in the pump well; recording the main line inflow amount and the flow time corresponding to the main line inflow amount in association with each other to calculate an actual flow time corresponding to the main line inflow amount from the rainwater inflow amount and the main line inflow amount; compensating the flow time using a measured flow time corresponding to the main line flow rate; and calculating a predicted value of the rainwater inflow amount using the main line inflow amount, a corrected flow time, and a predicted time required for controlling a rainwater pump installed in the pump well 14.SELECTED DRAWING: Figure 2 【課題】 精度よく雨水流入量予測を行う雨水流入量予測装置を提供する。【解決手段】 実施形態による雨水流入量予測装置は、複数の地点における幹線流速と幹線流量とを算出し、複数の地点における幹線流速と、複数の地点からポンプ井１４までの幹線延長とから、複数の地点からポンプ井１４までの流下時間を算出し、複数の水位計およびポンプ井に設置された流入渠水位計のいずれかで測定された水位を用いて、ポンプ井１４に流入する雨水流入量を算出し、幹線流量と幹線流量に対応した流下時間とを関連付けて記録するとともに、雨水流入量と幹線流量とから、幹線流量に対応する実測流下時間を算出し、幹線流量に対応する実測流下時間を用いて流下時間を補正し、幹線流量と、補正後の流下時間と、ポンプ井１４に設置された雨水ポンプ制御に必要な予測時間と、を用いて、雨水流入量の予測値を算出する。【選択図】図２
