“…There is a significant number of studies that assess the potential of hydropower using GIS based approaches [31,[34][35][36][37][38][39][40][41][42][43][44][45][46][47]. The majority of these studies however, are focused on a particular hydrological unit (basin, sub-basin) or on a country level.…”

“…In addition to that, the addition of a geo-spatial component in such assessments can help answering questions regarding proper site selection and lead to better allocation of (usually) scarce financial resources.Geographic Information Systems (GIS) and modern remote sensing techniques convey useful information that can add significant value in hydropower assessments. Their integration can provide useful insights to policy makers and developers regarding the future deployment and spatial distribution of distributed generation systems, including among them new hydropower plants [20].There is a significant number of studies that assess the potential of hydropower using GIS based approaches [31,[34][35][36][37][38][39][40][41][42][43][44][45][46][47].

A Geospatial Assessment of Small-Scale Hydropower Potential in Sub-Saharan Africa

et al. 2018

Sub-Saharan Africa has been at the epicenter of an ongoing global dialogue around the issue of energy poverty. More than half of the world's population without access to modern energy services lives there. It also happens to be a sub-continent with plentiful renewable energy resource potential. Hydropower is one of them, and to a large extent it remains untapped. This study focuses on the technical assessment of small-scale hydropower (0.01-10 MW) in Sub-Saharan Africa. The underlying methodology was based on open source geospatial datasets, whose combination allowed a consistent evaluation of 712,615 km of river network spanning over 44 countries. Environmental, topological, and social constraints were included in the form of constraints in the optimization algorithm. The results are presented on a country and power pool basis.Energies 2018, 11, 3100 of 21Recent studies indicate that the decentralization (typically of a scale less than 10 MW) of energy systems can help in addressing energy poverty [9][10][11][12][13][14]. Off-grid or mini-grid systems can be a viable near-term alternative to grid extension in many parts of Sub-Saharan Africa [15]. The prospect for decentralized energy supplies are further enhanced by the continent's abundant renewable resources. Further, the local employment is developed for deployment and maintenance of local renewable electricity generating equipment [5]. A cornerstone in the movement towards renewables is hydropower [16,17]. Role of HydropowerHydropower is a technically mature and economically competitive renewable energy source that can provide significant advantages in the operations and stability of energy systems [16]. Across Africa, hydropower is responsible for 74.2% of all non-fossil fuel electricity use [18]. In 2017 the total installed hydropower capacity in Africa was 35.34 GW [16], producing approximately 131 TWh of electricity; hydropower accounts for about 21% of the total installed capacity in the continent [16,18,19]. Focusing on Sub-Saharan Africa, the installed hydropower capacity (as in 2017) was estimated at 30.4 GW [16]. Despite this, around 92% of the 300 GW potential still remains untapped [20].The opportunities for expanding hydropower are considerable and could help support electricity provision in remote African communities, especially when developed in a small, decentralized scale [21,22]. Given favorable hydrological conditions, hydropower offers a relatively low levelized cost, continuous generation without storage requirements, and the ability to operate both in isolated or interconnected (to a national grid) mode [23]. It is estimated that the installed capacity of small-scale hydropower (below 10 MW) in Sub-Saharan Africa surpasses 476 MW [24,25].According to [21,24], the small-scale hydropower resource potential in the region is estimated at 12,197 MW, with the eastern part of the continent showing the highest potential. Szabo et al. [9] consider small-scale hydro as a very suitable option for rural electrification in Africa, showing high poten...

“…Both GIS and RS techniques have been used in the past for the assessment of hydropower potential: Pokharel (2000) performed spatial analysis using GIS to develop location-specific energy resource and consumption profiles in rural areas of Nepal; Ramachandra and Shruthi (2007) applied GIS to map the renewable energy potential of taluks (subdistrict administrative units) in Karnataka State, India; Belmonte et al (2008) applied GIS in the territorial planning of Lerma Valley (Salta, Argentina) for mapping potential energy resources, taking into account environmental diversity and site conditions (topographic, natural resource, infrastructure and service availability, social and economic); Coskun et al (2010) determined the hydro-electric water potential of a poorly-gauged basin (Solakli) in the eastern Black Sea region of Turkey using RS and GIS; and Kusre et al (2010) assessed the hydropower potential of Kopili River basin in Assam, India using GIS and the Soil and Water Assessment Tool (SWAT) model. Ramchandra et al (2004) developed a spatial decision support system (DSS) for assessing the hydropower potential of micro-, mini-scale and small projects.…”

In this study, a hydrological model and spatial technologies have been employed to assess water availability in the Mat River basin, southern Mizoram, India. Furthermore, the results obtained from the SWAT (Soil and Water Assessment Tool) model, satellite data and GIS tools were utilized to identify the hydropower potential in the basin. Thirty three sites with hydropower potential were identified within 147 km 2 of the Mat River basin. A total of 3039, 1127 and 805 kW can be harnessed with 50, 75 and 90% dependability, respectively. The study revealed that the hydropower potential of a river basin can be correctly assessed by employing a digital elevation model, stream network data and a hydrological model, such as the SWAT model, within a GIS framework.

“…Due to the above-mentioned facts, the use of geomorphology GIS, remote sensing GIUH for rainfall-runoff models for poorly gauged basins has attracted the attention of many researchers and presently a lot of work is being published in this regard (Ahmad et al 2010;Dave et al 2010;Coskun et al 2010;Cao et al 2010;Ahmad 2009;Rai et al 2009;Nguyen 2008;Sarangi et al 2007). Bhaskar et al (1997) showed that temporal distribution of rainfall excess has no marked effect on GIUH simulation.…”

Hill torrents cause a lot of environmental and property damage in Pakistan every year. Proper assessment of direct runoff in the form of hill torrents is essential for protection of environment, property, and human life. In this paper, direct surface runoff hydrograph (DSRH) was derived for a large catchment using the geomorphologic instantaneous unit hydrograph concept. The catchment with hill torrent flows in semi-arid region of Pakistan was selected for this study. It was divided into series of linear cascades and hydrologic parameters required for Nash's conceptual model, and were estimated using geomorphology of the basin. Geomorphologic parameters were derived from satellite images of the basin and ERDAS and ArcGIS were used for data processing. Computer program was developed to systematically estimate the dynamic velocity, its related parameters by optimization and thereby to simulate the DSRH. The data regarding rainfall-runoff and satellite images were collected from Punjab Irrigation and Power Department, Pakistan. Model calibration and validation was made for 15 rainfall-runoff events. Ten events were used for calibration and five for validation. Model efficiency was found to be more than 90% and root mean square error to be about 5%. Impact of variation in model parameters (shape parameter and storage coefficient) on DSRH was investigated. For shape parameter, the number of linear cascades varied from 1 to 3 and it was found that the shaper parameter value of 3 produced the best DSRH. Various values of storage coefficient were used and it was observed that the value determined from geomorphology and the dynamic velocity produced the best results.
