It originates from Jidantou (both Maying) in Shigou Town, flows through Daping, and goes down to Wandong in Huangtian to join the Suijiang River. The water collection area is 101 square kilometers, the river length is 22 kilometers, and the average slope of the river bed is 3.6‰. Heli River: Also known as Dengzhai River, it is a secondary tributary of Suijiang River and a tributary of Longjiang River.

Among the characteristics of the rivers in the territory, the Suijiang and Longjiang are most closely related to floods and droughts, while the rise and fall of the Beijiang and Xijiang rivers have an important impact on the water levels of the Suijiang and Longjiang. In ancient times, there was a saying "If the Xijiang rises, the Qingqi will rise." If the mouth of the river cannot absorb water from the tributaries of the river; if the Beijiang River rises, the mouth of Nanjin cannot absorb the water of the runoff of the river." The Beijiang River is the main water outlet of the Suijiang River. If the water rises, the water in the Suijiang River will be difficult to subside. The Xijiang River is the largest water system in the Pearl River Basin, with rich runoff and ferocious floods. It has the characteristics of large peak volume and long duration. The Suijiang River starts from Taoye Mouth. It is diverted to the Qingqi River and flows out of the Xijiang River. It is often supported by the floods of the Xijiang River, causing the water level to rise. The city's average annual surface water runoff is 1.25 billion cubic meters, and the transit passenger water runoff is 7.08 billion cubic meters. There is a big difference between wet years and dry years; the sediment content of the water flow, the average annual sediment transport rate is 0.345 kg/s, and the sediment transport rate is 0.345 kg/s. The volume is 1.184 million tons.

【Climate】

Most areas within the territory are south of the Tropic of Cancer and have a subtropical monsoon climate with relatively high humidity, abundant heat, sufficient sunlight, abundant rainfall, a warm climate, a long frost-free period, and are suitable for farming in all seasons. Spring (according to the lunar calendar, the same below): From the beginning of spring to Grain Rain, the stationary front in South China is frequently active, with low temperatures, lots of rain, and less sunshine. After the Jingzhe, the temperature gradually rises and the rainfall becomes more and more, leading to the rainy season and the first flood season. At this time, cold air continues to move southward, and in a few years there will be "late spring cold" around the vernal equinox. Sometimes there will be one or two local hailstorms during the Grain Rain; at the same time, when the warm and humid air currents are weak and the dry and cold air is obvious, spring drought will occur in some years. Summer: From the beginning of summer to the summer, typhoons become active due to the influence of frontal troughs and ocean warm and moist airflow, which is the time when rainfall is most concentrated. Around the Dragon Boat Festival, "dragon boat water" usually appears. During this period, the temperature also increased significantly. During the period from Minor Heat to Major Heat, the highest temperatures of the year often occur. Due to strong heat convection, there are sometimes strong winds, thunderstorms and typhoons. After the Great Heat, there are mostly typhoons and hot thunderstorms, but under the control of subtropical high pressure, high temperature, drought and hot weather will also occur. Autumn: From the beginning of autumn to the frost, there will be a post-flood season before the autumnal equinox due to the control of the Pacific subtropical high pressure and the influence of typhoons. After the autumnal equinox, the activity of warm and humid air flow weakens, and the cold air from the north begins to move southward, causing the weather to become cooler, resulting in high and cool autumn weather. Before and after the cold dew, cold air frequently invades, causing "cold dew wind" weather. At this time, typhoon activity decreases and is stably controlled by the subtropical high pressure and the cold high ridge on the ground, resulting in long summers and short winters. The temperature distribution gradually decreases from southeast to northwest. The annual average temperature is about 19.8℃ in Weizheng Town and Jianglin area of ​​Jianggu Town in the north, about 21.5℃ in Dasha Town in the south, and about 20℃ in other areas. Rainfall decreases and autumn drought is prone to occur. Winter: The beginning of winter is a severe cold. Affected by the cold air and cold wave from the north, the climate is dry, the temperature drops, there is frost from time to time, and there is occasional ice in the northwest mountainous area. Under the influence of strong cold air, minor cold to major cold are the extremely cold periods of the year. In 2022, the climate in Sihui City will be inconsistent. The overall characteristics of the weather and climate throughout the year are: floods start early, "dragon boat water" is strong, extreme, and local floods are severe; the first typhoon is late, and there are many landfalling typhoons; there are many high-temperature days with high intensity Strong; the weather is obviously droughty in autumn. The annual average temperature is 21.9°C, basically the same as normal. There were 43 high-temperature days (daily maximum temperature ≥35°C) throughout the year, 14.7 days more than normal. Among them, the highest temperature was recorded on July 30 at 38.8°C. The number of sunshine hours was 1701.0 hours, 89.0 hours more than normal. The flood season started on March 24, which is earlier than normal (April 8). The annual rainfall is 1984.2 mm, about 10% more than normal. May 21st to June 20th is the period of concentrated rainfall ("Dragon Boat Water"), with a cumulative rainfall of 356.1 mm, 19% more than the same period in normal years (299.0 mm). There were 4 typhoons that affected Sihui City during the year, one of which was a tropical depression, and the others were Typhoon No. 2203 "Siamba", Typhoon No. 2207 "Mulan", and Typhoon No. 2209 "Ma'an". Among them, Typhoon No. 2203 "Siamba" "It has a serious impact on Sihui City, which has the characteristics of "strong typhoon intensity, wide impact range, large accumulated rainfall, and high disaster risk". Affected by this, from 08:00 on July 2 to 08:00 on July 6, heavy to heavy rainfall occurred in Sihui City. The average rainfall in the city was 194.8 mm. The maximum cumulative rainfall was 237.4 mm at Jianggu Reservoir in Jianggu Town. The maximum daily rainfall was at Huangtian Town Water Conservancy. The maximum wind speed was 135.1 mm (occurred on July 2); the maximum wind speed was 17.6 m/s (level 8, occurred at 18:13 on July 2) in Dengcun Neighborhood Committee, Zhenshan Street.
