2023年M沟水量监测报告

2023M水量监测报告20233流域概况4230m，2500m。M〔152mm，M流。M沟为白杨河的一条支流，发源于天格尔山东部低山区，流域海拔最高4230m，源头无冰川，高山区降水约150mm，水系发育稀疏，呈羽状水系。该沟是一条典型的泉水沟，流域山区降水形成地表径流后，经下渗蒸发，在沿途河谷断续有泉水溢出，并在下游M18km植物种类以梭梭、红柳、骆驼刺等耐旱灌木为主。水文测验与资料整编水文测验状况111231E88°12′3631〔1。10.0010.009.50河底高程9.00〔m〕8.508.00051015202530起点距〔m〕图1 2023年M沟测流断面图水文资料整编状况水位：因测验河段长期无人居住，未设立水尺，因此无水位资料。整编主要以电算为主。料牢靠，精度较高，可满足本次水文分析计算的需求。成果分析整编成果经2023年施测水量分析，该沟年内水量变化不明显，计算年平均流量为0.945m3/s，370.181m3/s，210年内变化平均流量0.50(m3/s〕12平均流量0.50(m3/s〕1234567891011 月份22023M四季安排变化20.9%-31.3%，其中春季水量在占年比例较大，夏、冬、秋季水量相对平缓。年份年份春季〔3-5〕夏季〔6-8〕秋季〔9-11〕冬季〔12-2〕〔10m3〕 〔10m3〕 〔10m〕 〔10m3〕年水量〔10m3〕2023290.771203.558240.399193.787928.515占年比例31.3%21.9%25.9%20.9%提交的主要成果〔1〕2023年M沟实测流量成果表〔2〕2023年M沟逐日平均流量表结论及建议928.515×104m3202383666×104m325.3%，主要缘由：〔1〕2023〔3监测。〔2〕四周无人居住或无监控系统无法了解到洪水过程。和整编资料牢靠，可供参考。施测号起月日施测号起月日时:止时:断面位置测验方法根本水(m)流量(m3/s)断面面积(m2)流速(m/s)平均最大数分分11117:5018:02基流速仪5/0.60.2470.260.951.1021514:5015:10〃〃7/0.60.2340.260.901.1132712:5613:04〃〃5/0.60.2450.290.841.00421015:5016:10〃〃5/0.60.1810.280.650.8552015:4015:52〃〃7/0.60.2570.320.801.1762714:1014:25〃〃5/0.60.2600.300.871.0273713:1013:16〃〃6/0.60.9450.511.854.2882112:5012:58〃〃5/0.60.2740.300.911.2394212:4012:50〃〃5/0.60.2910.360.811.11101214:4514:55〃〃5/0.60.2390.330.721.11112416:0016:10〃〃5/0.60.2810.300.941.21123012:3013:00〃〃5/0.60.2930.320.921.30135912:5413:00〃〃5/0.60.2820.300.941.35142412:2012:40〃〃6/0.60.3670.301.221.65156313:3513:45〃〃6/0.60.2650.261.021.33161212:3013:00〃〃7/0.60.2030.320.620.95172613:1013:16〃〃5/0.60.1900.200.951.16187214:4014:50〃〃5/0.60.2450.320.771.011914:5215:02〃〃5/0.60.2320.320.720.91201615:2015:30〃〃5/0.60.2840.310.921.26212515:0015:12〃〃5/0.60.2820.330.851.02223112:5013:00〃〃5/0.60.3000.301.001.23238714:1014:20〃〃5/0.60.3030.281.081.53241515:1815:28〃〃5/0.60.3050.251.221.53252615:0015:12〃〃5/0.60.2280.300.760.92施测号数起根本施测号数起根本月日时:止时:断面位置测验方法水尺水位流量(m3/s)断面面积(m2)流速(m/s)说明：全年涉水施测。分分(m)平均最大269413:4013:50〃〃5/0.60.2680.251.071.34271613:5214:00〃〃6/0.60.2760.290.951.28283012:5613:04〃〃5/0.60.3620.311.171.5129101014:1514:25〃〃5/0.60.3260.311.051.31301714:0014:10〃〃8/0.60.3160.340.931.2131102813:0113:11基流速仪5/0.60.3080.320.971.2232111212:5813:10〃〃6/0.60.2900.390.741.05332214:0214:12〃〃4/0.60.3260.340.961.433412415:1015:16〃〃6/0.60.2320.410.571.21351212:2412:30〃〃6/0.60.2660.320.831.07363113:1013:15〃〃5/0.60.3250.301.081.372023年M12123456789101112日期10.2470.2220.4240.2890.2920.2860.2340.30.2550.3580.3030.25720.2460.2180.510.290.2910.2760.2380.3010.2590.3550.3020.24930.2450.2130.5960.2860.290.2660.2360.3010.2630.3510.3010.24140.2440.2090.6820.2810.2880.2590.2390.3020.2670.3480.30.23450.2430.2040.7680.2760.2870.2520.2430.3020.2690.3440.2990.23660.2420.20.8540.270.2860.2450.2460.3020.2690.340.2970.2470.2410.1950.9270.2650.2850.2380.250.3030.270.3370.2960.24580.240.1910.8990.260.2830.2310.2540.3030.2710.3340.2950.24990.240.1860.8510.2550.2830.2240.2580.3030.2710.330.2940.253100.2390.1830.8040.250.2880.2170.2620.3040.2720.3260.2930.258110.2380.1870.7560.2450.2930.210.2650.3040.2730.3250.2910.262120.2370.1950.7080.240.2990.2040.2690.3040.2730.3240.290.266130.2360.2020.660.2420.3050.2020.2720.3040.2740.3220.2940.268140.2350.210.6120.2460.310.2010.2760.3050.2750.3210.2970.272150.2340.2180.5640.2490.3160.20.280.3040.2750.3190.3010.276160.2350.2250.5160.2520.3220.1990.2830.2990.2770.3180.3040.278170.2360.2330.4680.2560.3270.1990.2840.2920.2820.3160.3080.282180.2360.240.420.260.3330.1980.2840.2850.2880.3150.3120.284190.2370.2480.3720.2630.3390.1970.2830.2780.2940.3150.3150.288200.2380.2560.3240.2660.3440.1960.2830.2710.30.3140.3190.29210.2390.2570.2810.270.350.1950.2830.2640.3060.3130.3220.294220.240.2580.2750.2740.3560.1940.2830.2570.3120.3130.3250.296230.2410.2580.2770.2770.3610.1930.2830.250.3190.3120.3190.3240.2420.2590.2780.280.3650.1920.2820.2430.3250.3110.3110.302250.2430.2590.2790.2820.3570.1910.2820.2360.3310.310.3040.306260.2440.2590.2810.2840.3470.1910.2840.230.3370.310.2960.308270.2450.2670.2820.2860.3360.1980.2880.2320.3430.3090.2880.312280.240.3380.2840.2880.3260.2080.290.2370.3490.3080.280.314290.2360.2850.2910.3160.2160.2940.2410.3560.3070.2720.318300.2310.2860.2930.3060.2260.2960.2460.3610.3060.2640.32310.2270.2880.2960.2990.250.3050.324平均 0.2390.228平均 0.2390.2280.510.2690.3150.2170.2710.2790.2940.3230.30.278最大0.2470.3810.9450.2930.3670.2910.30.3050.3620.360.3260.325日期12873024131143012231最小0.2250.1810.2740
