1.1 Brief Introduction to the Project
1.1.1 Project Class and standard
The Project is is a multipurpose project, which takes shipping as the main purpose, gives consideration to power generation and flood control. The project belongs to second-class large (2) type project, with normal impounding level of 56.50m, total reservoir capacity of about 632 million m3, the reservoirarea at normal level of 29.2km2，backwater length of 38km，6 water turbine power generating sets, installed capacity of 117MW，annual average power generating capacity of 4.8×108kW·h，belonging to low head building.
The protection work of the reservoir area is composed of five protection areas of TaiheCounty seat, Wanhe, Yongchang, Yanxi and Zhangtang.
⑴ Engineering grade and flood control standard
The village protection work is Grade IV, the protection work of the TaiheCounty seat is Grade III, their flood control standard reoccurrence periods are 10～20 years and 20～50 years respectively. The flood reoccurrence periods of the protection work of the TaiheCounty seat and the village protection work are respectively 20 years and 10 years.
The Wanhe Drainage Pumping Station, the Yanxi Drainage Pumping Station, and the Jintan Drainage Pumping Station belong to middle scale pumping stations. The building grade of the said three pumping stations are the same with that of the fending groynes in which they are located, belonging to Grade 4, the design flood standard is once-every-10-year-flood. The building grade of Huangjiaba and Dongmen drainage pumping stations are the same with that of the fending groynes of the TaiheCounty seat, belonging to Grade 3, the design flood standard is once-every-20-year-flood.
The Zhangtang Regulating Sluice is of middle scale gate, Grade 3 building, with design flood standard of once-every-20-year-flood; The Wanhe Regulating Sluice is of small (1) type gate, Grade 4 building, with design flood standard of once-every-10-year-flood. The crest elevations of typical sections of fending groynes of each protection area are shown in Table 1.1-1.

⑵ Drainage design standard
For the protection area with villages and towns, the drainage standard is to apply a once-in-a-five-year 3-day rainstorm and drain to the inundation resistant depth within 3 days; the drainage standard of the Taihe County seat is to apply a once-in-a-10-year 1-day storm and drain to the elevation of main buildings non-inundated within 1 day, indicated in the Preliminary Design Report of Flood Control Work of the Taihe County Seat by Ji’an City Water Conservancy and Hydropower Plan and Design Institute; The drainage standard of the guide support canal within the protection area is to apply the corresponding drainage reoccurrence period standard of the protection area, the foreign water guide support canal (river) within the protection area is based on the design flood standard of the fending groyne of the protection area.
1.1.2 Arrangement of protection works
The engineering contractor has designed and arranged five protection areas of Wanhe, Yanxi, Zhangtang, Yongchang and Taihe County Seat. The total length of fending groyne lines of the protection works is 38.38km, including 3.36km Taihe Fending Groyne，8.12km Wanhe Fending Groyne，0.80km Zhangtang Fending Groyne，15.79km Yongchang Fending Groyne and 10.32km Yanxi Fending Groyne，the total length of guide support canal is 61.33km，including 17.18km long county seat guide support canal to be dredged and resumed as per the original section，14.45km Yongchang Guide Support Canal to be refit as per the design standard，29.70km Yanxi and Wanhe guide support (drainage) canals to be built；11.85km diversion canal to be refit；6 new pumping stations with total installed capacity of 5456kW and 2 new regulating sluices.
The arrangement of all the protection works is shown in Table 1.1－2.
⑴ Fending groyne design
The designed fending groyne types are as follows:
Wanhe Section: ~1km long fending groyne close to the pivot area is a clay core pebble one, flood wall is locally applied for earth rockfill fending groyne section with restriction, the remained part is earthen groyne.
Zhangtang Section: the whole section is made of homogeneous soil groyne.
Jintan Section: ~5km long homogeneous soil groyne is arranged near the excavated place of the YuntingRiver rerouting and along the upstream of the Yunting River，flood wall is locally applied for earth rockfill fending groyne section with restriction, the remained part is clay core pebble groyne.
Yanxi Section: ~1.6km long homogeneous soil groyne close to YanxiTown with application of the existing groyne, flood wall and wave protection wall are locally applied for earth rockfill fending groyne section with restriction, the remained part is clay core pebble groyne.
Taihe Section: the whole section is made of clay core pebble groyne.
① Groyne type design
Clay core pebble groyne: the inside and outside slopes are in gradient 1:1.8, the river-facing groyne is face protected with C15 prefabricated slab with protection slope thickness of 0.15m，downstream slope is of grassed slope, groyne top has cemented stone road and 0.6m high wave protection wall. The groyne body is built with pebble and with clay core for antiseepage, crest width of 2m，gradient of 1:0.25. C15 concrete drain ditch is set at the back of the groyne with depth of 0.5m and bottom width of 0.5m.
Homogeneous soil groyne: the river-facing groyne is face protected with C15 prefabricated slab with protection slope thickness of 0.15m and o.15m thick bedding pebble，gradient of 1:2.5, downstream slope is of grassed slope, groyne top has cemented stone road and 0.6m high wave protection wall with gradient of 1:3. The groyne body is built with homogeneous clay for antiseepage. Drain ditch is also set at the back of the groyne.
Flood wall: C20 concrete gravity wall, top width of 1.5m and back slope gradient of 1:0.3.
② Groyne foundation antiseepage
When the ground elevation of the protected object at back of the groyne is higher than the backwater elevation of the reservoir area at 4700m3/s, impervious wall shall be built at the groyne foundation to assure the safety of the protection area.

⑵ Arrangement of drainage pumping stations (regulating sluices)
The drainage pumping stations (regulating sluices) of every protection area are set at the discharge of the original canal within the protection area. Considering when standard-exceeding flood happens, the protection area will be filled fully with water, which is required to drain out timely after flood, axial flow pumps will be applied, the pump house shall be of wet house type, composed of pump storey and motor storey, the ground elevation of pumping stations shall be filled up flush with groyne top.
⑶ Arrangement of guide support (diversion) canals
Guide support canal line, section guide drainage flow, landform, geology, houses and farmland distribution along the canal line will be decided as per related code, try to minimize house relocation, land occupation, and to make full use of the existing drainage canals. The longitudinal slope of canal normally i＝0.00015～0.00050, earth canal at side slope of excavated canal m＝1.5，stone canal m＝0.75，fill canal m＝1.50，flow in canal meets the condition of no scouring and no silting. Canal top superelevation is calculated as per h/4+0.2, canal outlet level is not lower than the level of the outside river. The top width of fill section of guide support canal is 2.0m.
1.1.3 Main inundated substances of the reservoir area
After the fending groynes and farmland elevating measures, the Project is still involved in inundation of five townships, one reclamation farm, forty-four administrative villages of TaiheCounty. Main inundated substances of the upper dam site plan (the recommended plan) at normal impounded level of the reservoir area 56.5m are as follows:
After the fending groynes and farmland elevating measures, the reservoir inundation and the bury of protection works will need to permanently occupy 2829.8Mu farmland (including 701.85Mu paddy field, 2127.9Mu dry land, among which there are 198.27Mu basic farmland), 104.4Mu garden plot, 3130.9Mu other types of land, 32588.6Mu water area; It is involved in relocation of 711 people, impacts of 8 enterprises and institutions, house relocation of 4.56×104m2 and fence relocation of 6392.59m2，11610m2 cement ground, 48 simple buildings, 8 wells, 161 pressing wells, 1 water tower, 221 tombs, 1576 odd fruit trees; 2.21km Grade 4 road, 10.71km tractor road, 18 ferries and docks, 8.62km aerial fiber cable，5.84km underground cable，2.48km CATV line，5.03km 10kV transmission line，7.55km 0.4kV transmission line，3 transformers, 1 tiny hydropower station (200kW), 15 small electrical pumping stations, 1 water plant, 27 sand picking facilities and some other facilities.
