The main hydrological center in Nigeria is the Jos Plateau. The Jos Plateau is located in central Nigeria and is characterized by high elevation, cooler temperatures, and abundant rainfall. The plateau is the source of several rivers, including the Kaduna, Gongola, and Niger rivers, which are important for irrigation, transportation, and hydroelectric power generation. In addition to its role in Nigeria's water supply, the Jos Plateau is also known for its rich mineral deposits, including tin, limestone, and iron ore, which have contributed to the region's economic development. Overall, the Jos Plateau plays a crucial role in Nigeria's hydrology, providing water resources for agriculture, industry, and domestic use.
