摘要

灌溉是从可用水源向农业地区提供、调节和分配水以满足作物需求。灌溉在实现和提高国民粮食水平方面发挥着非常重要的作用，如D.I Cingkariang Banda Patah Nagari Padang Lua灌溉通道。Banda Patah Nagari Padang Lua灌溉网络的第三通道灌溉面积为±100公顷的稻田。班达巴塔农业用地的用水需求无法得到适当满足。在灌溉网规划中，必须进行设计分析，包括雨量分析、流量计算、渠道尺寸等。对班达巴塔三级河道进行评价的主要目的是确定班达巴塔农业区的用水需求和充足程度。通过对管网的升级改造，可以根据需要充分提供所需的水。在规划通过降雨过程得到的通道尺寸时，采用Haspers法和Gumbel法。野外三级河道尺寸计算结果为1.03 m³/s，规划尺寸计算结果为5.42 m³/s。评价结果表明，现有班达坝灌溉网三级通道的尺寸不能满足最大流量，规划通道的尺寸可以满足最大流量。关键词:流量，沟道尺寸，降雨，甘贝尔，哈斯，三级沟道

EVALUASI SALURAN TERSIER D.I CINGKARIANG BANDA PATAH NAGARI PADANG LUA KECAMATAN BANUHAMPU KABUPATEN AGAM

Irrigation is the provision, regulation and distribution of water from available water sources to agricultural areas for crop needs. Irrigation is very important in the fulfillment and improvement of national food, such as the irrigation channel D.I Cingkariang Banda Patah Nagari Padang Lua. The tertiary channel of the Banda Patah Nagari Padang Lua irrigation network irrigates a rice field area of ± 100 ha. The water needs for Banda Patah's agricultural land cannot be met properly. In the Irrigation Network Planning, design analysis must be carried out which includes analysis of rainfall, calculation of discharge, and channel dimensions. The main objective of the evaluation of the Banda Patah tertiary channel is to determine the need and adequacy of water in the Banda Patah agricultural area. By upgrading the network, water needs can be provided adequately according to needs. In planning the channel dimensions obtained through the rainfall process using the Haspers method and the Gumbel method. The results of calculations from the tertiary channel dimensions in the field obtained a discharge of 1.03 m³/s and the results of the planned dimensions obtained a discharge of 5.42 m^3/s. Based on the evaluation, the dimensions of the tertiary channel of the existing Banda Patah irrigation network cannot accommodate the maximum discharge, and the dimensions of the planned channel can accommodate water at the maximum discharge.Keywords : Discharge, channel dimensions, rainfall, gumbel, haspers, tertiary channel
