In this study, a methodology has been proposed that can be used to estimate the peak unit discharge for all the watersheds in the northern part of Cyprus. Thus, the Soil Conservation Service method was used to determine the unit hydrographs of 366 watersheds available in the study area. Through the Digital Elevation Model with a spatial resolution of 12 m the watershed characteristics such as watershed boundaries, area, slope, and streams were defined. Runoff curve number maps for each watershed were created by the integration of the land use/land cover and soil data within a Geographic Information System technique. In the end, through genetic algorithm optimization, a dimensionally homogenous formula as a function of basin parameters was developed. The developed function can be used to estimate the unit discharge at ungauged watersheds of the northern part of Cyprus with a high degree of accuracy. Furthermore, an empirical equation based on morphometric watershed characteristics was also formulized to replace the time of concentration with parameters that directly affect the time, such as Bifurcation ratio and drainage density. The proposed empirical equation estimates the unit discharge in all the watersheds with the mean relative error of 11.97%.

在这项研究中，提出了一种方法，可用于估算塞浦路斯北部所有流域的峰值单位流量。因此，土壤保护服务方法用于确定研究区域内366个流域的单位水位图。通过具有12 m空间分辨率的数字高程模型，可以定义流域特征，例如流域边界，面积，坡度和河流。通过在地理信息系统技术中整合土地利用/土地覆盖和土壤数据，创建了每个流域的径流曲线数图。最后，通过遗传算法优化，开发了尺寸均一的公式，作为盆地参数的函数。所开发的函数可用于高度准确地估算塞浦路斯北部未开垦的流域的单位流量。此外，还建立了一个基于形态学分水岭特征的经验方程，用直接影响时间的参数（例如分叉比和排水密度）代替集中时间。提出的经验公式估算了所有流域的单位流量，平均相对误差为11.97％。
