“…Thus the water accumulated in the tank after monsoon should percolate at the earliest, without much evaporation losses [82] . These structures are built mainly to impound monsoon runoff over a large area to augment groundwater recharge [79] . Moderate to high porosity of soil and/ or underlying rocky strata is the main criteria for the choice of percolation tanks [37] .…”

Groundwater is an essential component of the environment and economy which sustains the flow in our rivers and plays an important role in maintaining the fragile ecosystems. The groundwater dependence of agrarian states like Karnataka is high. Major water sources are under serious threat due to gradual increase in population, climatic change, over withdrawal of groundwater, immense agricultural practices, deforestation and from other sources around the world. Recent studies indicate that 26% of the area of Karnataka State is under over exploited category and number of blocks is under critical category. Within the state, the irrigated agriculture planking further stress on the groundwater system and desires appropriate management of the resources. The present study aims to augment groundwater resources in stressed areas of Mysuru taluk for groundwater sustainability. Survey of India (SoI) topomap, IRS-1D, PAN+LISS-III and ASTER G-DEM satellite data are effectively utilized through GIS environment. Efforts have been made to evaluate the thematic layers of geology, geomorphology, drainage density, lineament density, soil, slope, land use/ land cover, rainfall and overlay weightage analysis using GIS environment. The derived thematic layers have been assigned suitable ranks and weightages using Analytical Hierarchy Process (AHP) depending on the features Sustainable… Manjunatha et al.

“…This local recharge cannot be generalized to the entire watershed but was consistent due to the proximity of piezometric wells and the sparse hydrographic network of the study area. Similar technologies were developed in some countries not to practice SI, but rather to contribute to the groundwater recharge by harvesting rainwater [37] [38]. Thus, the implementation of the ten thousand basins construction initiated by the Burkinabe government and its partners in the Sudano-Sahelian zone would inevitably affect the hydrology of watersheds.…”

This study was carried out in the Burkinabe Sahel aimed at studying contribution of the practice of supplemental irrigation (SI) via excavated rainwater harvesting basin (RWHB) for mitigating effect of rainfall variability on agricultural production and impact of these RWHB on the dynamics of the water table. This study was conducted during two growing seasons (2013 and 2014) and used a test plot cultivated in corn and fitted out with measuring instruments to analyze water transfer in the soil-plant-atmosphere system on the one hand and the atmosphere-RWHB-water table system on the other hand. Four treatments-one under rainfall regime (T0) and three under SI (T1, T2, and T3)-were used in the experimental design to assess the contribution of the RWHB in improving corn yield. These SI were applied during the mid-season of corn (flowering, pollination, and grain filling). Water flow beneath a partially waterproofed RWHB was assessed using HYDRUS-2D/3D program. Results showed that water stored in the RWHB allowed applying up to three SI, and increased corn yield up to 24% and 26% respectively in 2013 and 2014. However, SI targeting flowering and grain filling were the best scenarios to mitigate effect of dry spell in rainfed agriculture. Water flow under RWHB during the simulation period showed that dynamic of the saturated front depended on the magnitude of the water depth in the RWHB and the hydrodynamic characteristics of the underlying layers. Deep drainage was observed around 25th day after sowing (DAS) in 2013 and 45th DAS in 2014 according to water profile. This caused the decrease of the infiltration rate in the RWHB that was associated with a significant rise of 4% of the water table level ten days later in 2014. Recharge rate was estimated at 0.5 mm•d −1 during the mid-season and the late season of corn. V. C. Doto et al.1319
