Analisis Ketersediaan Debit Aliran SUB DAS Sungsang dan Stanum dengan Metode Nreca

---

Humans have a fundamental need for water that must be met in terms of quantity, quality, and continuity. In line with the increasing population every year, the demand for clean water also increases. This population growth affects the balance between water needs and availability. Therefore, to determine the balance between water needs and availability in the Stanum Watershed, it is necessary to analyze the availability and water needs for both domestic and non-domestic sectors in Bangkinang District in the future year 2033. The NRECA method can be used to determine water availability. The NRECA model is a rainfall-discharge simulation method with a deterministic conceptual model. The available discharge is calculated using a probability calculation by taking 80% of the calculated discharge from 2012 to 2022. The recapitulation of 80% available discharge is calculated from January to December. The results of this visual test show that the Q80 reliable flow has a maximum reliable flow rate in November of 2740.48 L/sec. Meanwhile, the minimum reliable flow occurs in July, which is 3.25 L/sec. With an average reliable flow rate Q80 of 283.591 L/sec. The calculation of clean water needs depends on the number of residents. From the analysis of the population in Bangkinang District, it was found that in 2033 there will be 50.182 people (10-year projection). After analyzing the water needs in Bangkinang District in 2033, it is 122,70 L/sec. Based on the results of the water balance analysis, it is known that the water availability using the NRECA method is 283.591 L/sec and the water needs in the 2033 projection year are 122,70 L/sec. So, water availability ? water needs, so water availability is sufficient (surplus) for the 2033 population projection.
