摘要运用二维水流数值模拟方法，计算比较了在宜昌枝城的长江河段内选取重点控制河段，进行护底加糙及回填深槽对维护并抬高宜昌水位的效果。 - Comparison of water level between measured and computation shows that the local head loss coefficient cannot give head loss by spur dike completely , and the effective area of passage is difficult to be ascertain . for this reason the two methods for water surface profile computation cannot predict the raise of water level upstream the spur dike accurately
计算结果表明，局部水头损失系数并不能完全反映出由于丁坝阻挡所带来的水头损失，而丁坝附近的有效过水面积难以准确地确定，这些导致前两种方法均不能很好地计算出丁坝上游水位的壅高值。
