Flood and Renewable Energy Humanitarian Engineering Research: Lessons from Aggitis, Greece and Dhuskun, Nepal

Abstract

Climate and energy crises are increasing worldwide. Community-led humanitarian engineering interventions for localized sustainable development and disaster resilience could support populations at risk. This article presents findings from a study that investigated flood response and energy needs of two riparian communities in Greece and Nepal. The findings indicate that the co-development of a hybrid unit for hydropower generation and flood warning is most preferred. This prototype could find applications in different riparian areas as either a main or supplementary system.

Assessment of Flood-Induced Geomorphic Changes in Sidere Creek of the Mountainous Basin Using Small UAV-Based Imagery

“…The lateral channel morphological changes were mostly affected by factors such as channel confinement, channel slope, and sinuosity index (SI) [8,14]. The channel bed deposition and incision were affected by the channel slope, channel bed type (alluvial, semialluvial, or bedrock), and flow volume [7,8,11,74]. Any quarry activities and channel widening distribute suspended sediments to the streams.…”

River Flow Measurements Utilizing UAV-Based Surface Velocimetry and Bathymetry Coupled with Sonar

“…In the whole floodplain area of the Aggitis Basin, there is an extensive surface drainage/irrigation network including the drainage ditch of the Tenagi Philippon [81]. Flood events are a frequent phenomenon in the Aggitis Basin [82], especially in the area of Tenagi-Philippoi, but also in the floodplains of the local torrents which are the dominant water course type in the area. The specifically studied cross-section is located near Simvoli Village; the name "simvoli" (in Greek) means "confluence" (Figure 3) to describe the conjunction of Aggitis River with Agia Barbara stream and Xiropotamos stream (the last is the irrigation channel of Tenagi Philippon and the Doxato stream).…”
