表: 洪水シミュレーションの全般の設定項目と説明

設定項目		説明
河川	定期縦横断データの読み込み時の動作	河川の定期縦横断データのインポート時の動作を設定します。初期値は、「自動推定」です。「自動推定」: 節点名フラグを考慮した自動推定します。「節点名フラグに従う」: 節点名フラグを優先した設定になります。詳細はテクニカルリファレンス/ 河川モデル/ 縦横断データのインポートをご参照ください。
	縦断図の右を上流にする	河川断面図画面の縦断図を表示する方法を設定します。初期値は、「False」です。「False」: 縦断図の左側を上流にして表示します。「True」: 縦断図の右側を上流にして表示します。
流速表示	基準とする流速（m/s）	地図上に表示する流速ベクトル（矢印）の基準とする流速を指定します。
	矢印の最小長（%）	地図上に表示する流速ベクトル（矢印）の最小長を%で指定します。
	矢印の最大長（%）	地図上に表示する流速ベクトル（矢印）の最大長を%で指定します。
	矢尻の長さ（%）	地図上に表示する流速ベクトル（矢印）の矢尻の長さを%で指定します。
	間引き間隔	地図上に表示する流速ベクトル（矢印）の間引き間隔を指定します。
	表示色	地図上に表示する流速ベクトル（矢印）の色を指定します。

矢印の描画方法について

矢印を大きくしたい場合は、 [基準とする流速（m/s）] を小さい値にしてください。
矢印が込み合っている場合は、[間引き間隔] を大きい値にしてください。
なお、矢印は次の方法で描画されます。
- 流速が0ならば矢印は描画されない。
- 流速が0でないならば、流速 / [基準とする流速] * ([基準とする流速] の矢印の長さ) の矢印が描画される。
- ただし、(矢印の最小長) が最小、 (矢印の最大長) が最大となるように調整されます（clamp演算）。
- 間引き間隔1の場合、すべての矢印が表示されます。間引き間隔Nの場合、X方向およびY方向にN個おきに矢印が表示されます。
- ([基準とする流速] の矢印の長さ) = (セルの長さ) * [間引き間隔] * 1/2
- (セルの長さ) = sqrt((X方向のセルの長さ)^2 + (Y方向のセルの長さ)^2)
- (矢尻の長さ) = ([基準とする流速] の矢印の長さ) * [矢尻の長さ(%)] （個々の流速に関わらず一定の大きさ）
- (矢印の最小長) = ([基準とする流速] の矢印の長さ) * [矢印の最小長(%)]
- (矢印の最大長) = ([基準とする流速] の矢印の長さ) * [矢印の最大長(%)]
