“…and by those studies that include groundwater recharge from dam seepage (Ramireddygari et al, 2000;Barber et al, 2009;Smout et al, 2010;Shinde et al, 2010;Perrin et al, 2012). Therefore, seepage fluxes from each reservoir should not be aggregated to estimate the loss at the basin scale and thus for the estimation of the cumulative impacts of small dams on hydrology.…”

“…These approaches mostly focus on infiltration tanks, for which part of the stored volume recharges the aquifer. In such cases, only the impacts on the aquifer due to the loss from the reservoirs are represented, either without simulation of the groundwater (Martín-Rosales et al, 2007;Hughes and Mantel, 2010), with a simplified representation of the aquifer (Smout et al, 2010;Shinde et al, 2010;Perrin et al, 2012), or even more seldom, with a 2-D hydrogeological model (Ramireddygari et al, 2000;Barber et al, 2009).…”

The number of small reservoirs has increased due to their reduced cost, the availability of many favourable locations, and their easy access due to proximity. The cumulative impacts of such small reservoirs are not easy to estimate, even when solely considering hydrology, which is partially due to the difficulty in collecting data on the functioning of such reservoirs. However, there is evidence indicating that the cumulative impacts of such reservoirs are significant. The aim of this article is to present a review of the studies that address the cumulative impacts of small reservoirs on hydrology, focusing on the methodology and on the way in which these impacts are assessed. Most of the studies addressing the hydrological cumulative impacts focused on the annual stream discharge, with decreases ranging from 0.2% to 36% with a mean value of 13.4% ± 8% over approximately 30 references. However, it is shown that similar densities of small reservoirs can lead to different impacts on stream discharge in different regions. This result is probably due to the hydro-climatic conditions and makes defining simple indicators to provide a first guess of the cumulative impacts difficult. The impacts also vary in time, with a more intense reduction in the river discharge during the dry years than during the wet years. This finding is certainly an important point to take into consideration in the context of climate change. Two methods are mostly used to estimate cumulative impacts: i) exclusively data-based methods and ii) models. The assumptions, interests and shortcomings of these methods are presented. Scientific tracks are proposed to address the four main shortcomings, namely the estimation of the associated uncertainties, the lack of knowledge on reservoir characteristics and water abstraction and the accuracy of the impact indicators.

“…In addition to small reservoirs temporarily storing excess rainwater, they also play an important role in regulating downstream flows and can provide protection against flooding (Poolman, 2005). Another important contribution of these infrastructures is to contribute to the recharge of underground aquifers, thus increasing the base flow in the downstream section of the catchment area (Adwubi, et al, 2009;Habets et al, 2018;Shinde et al, 2011).…”

Small reservoirs play a key role in agricultural development in the Brazilian Savannah (Cerrado) region. They contribute to diminish rural communities’ vulnerability to drought and improve the livelihood of rural populations. Thousands of small reservoirs have been built in the last few decades in the Cerrado, but efficient water management and sound planning are hindered by inadequate knowledge of their water dynamics. Studies related to small reservoir water dynamics are generally scarce in the world hydrological literature. The main objective of this study was to develop a dynamic simulation model based on the system dynamics model to evaluate the water dynamics in small reservoirs over time, and the risk of not meeting the predicted water demand. Daily data on reservoir inflows were obtained for the period from October 2009 to September 2011, and extended to June 2015 through modeling. The developed model was calibrated and validated with historical data. The main variables which have impact on the water volume were evaluated through sensitivity analysis. The results indicated that reservoir inflow was the variable which had the highest impact on water volume in the reservoir, followed by the reservoir surface area and by evaporation and infiltration, which together represented 14.4% of reservoir inflow. The risk assessment of not meeting the predicted water demand showed that the water in the reservoir was above the critical level 85.9% of the time and that 81.6% of the reservoir water was available to meet water demand. Small dams pose a risk of not meeting the community’s water demand at least 18% of the time.
