SHP Assessment for a Run-of-River (RoR) Scheme Using a Rectangular Mesh Sweeping Approach (MSA) Based on GIS

This work proposed a base method for automated assessment of Small Hydro-Power (SHP) potential run-of-river (RoR) scheme using geographic information systems (GIS). The hydro-power (HP) was represented through comprehensive methodology consisting structured raster database. A calibrated and validated hydrological model (Soil Water Assessment Tool—SWAT) used to estimate monthly streamflow as the Mesh Sweeping Approach (MSA) driver. applied upper part Huazuntlan River Watershed in Los Tuxtlas Mountains, Mexico. MSA divided study area into rectangular mesh. Then, at every location within mesh, SHP obtained. main components RoR were intake, powerhouse, surge tank. tank located cells where calculated reference later locate intake powerhouse by maximizing discharge head. calculation performed sweeping under different values penstock’s length, headrace’s length. maximum permissible lengths these two variables generation locations. Results showed that length major contribution estimation. Additionally, 2000 m 1500 penstock headrace considered thresholds there is no significant increment after increasing any values. availability on representation has advantages further data analysis processing.
